Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 USC §119 to Korean Patent Application No. 10-2023-0022217 filed with the Korean Intellectual Property Office on February 20, 2023, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL AREA

The following disclosure relates to a multi-ply towel having excellent absorbency for double dyeing in a bath, and more particularly to a multi-ply towel capable of being dyed in various patterns by double dyeing a fabric having a terry structure by alternately arranging a first pile yarn and a second pile yarn in a bath.

BACKGROUND

Recently, studies on highly functional composite textiles with various functions have been actively carried out in the textile industry. In particular, the technological development of yarns and fabrics aims at differentiation and has been carried out to further advance the functionality of clothing, and the development of functional materials involving safe, healthy and high-quality products has been carried out to improve people's quality of life. The development of such functional materials has been carried out in various fields of the textile industry, and the field of daily necessities is no exception.

For daily necessities that come into direct contact with the skin, such as towels, it is important that they be soft, have excellent absorbency, and maintain cleanliness. In addition, the towels are required to be resistant to washing because they need to be washed frequently for the purpose of use. For this reason, cotton fiber is mainly used as the material for towels. The cotton fiber has high hygroscopicity, but because the cotton fiber contains a large amount of hydroxyl group (-OH), which is a hydrophilic group, in the main chain of cellulose which is the main component, absorbed moisture is not quickly removed and softness is deteriorated by repeated washing.

In addition, towels, which are generally used to remove moisture or sweat generated after bathing or exercising, should be able to quickly absorb the moisture or sweat remaining on the skin without causing skin irritation, although there is a limit when 100% cotton yarn is used.

To solve this problem, a blended yarn of synthetic fiber and natural fiber or a blended yarn of bamboo fiber and synthetic fiber can be used. However, due to the difference in dyeability and fastness of the synthetic fiber and the natural fiber, there will be a color difference of the final product, and the towel will look partially white due to repeated washing and rubbing.

Furthermore, the singular forms used in this description can also include plural forms, unless the context clearly indicates otherwise.

In addition, unless expressly stated otherwise, “comprehensive” any Components is understood to mean the further inclusion of other Components and not the exclusion of other Components.

In addition, terms such as first, second, (A), (B), (a), (b), and the like may be used in describing components of the present invention. These terms are used only to distinguish one component from other components, and features, sequences, or the like of corresponding components are not limited by these terms.

The term “filament thread” used in this description means that each filament consists of one or more continuous fibres in the form of filaments which are distributed over the entire length of a thread. The term "strand" can be understood to mean that it is formed by twisting several filament threads together.

The term "terry fabric" used in the present invention is generally referred to as a warp pile fabric and is a fabric in which a lower part (ground fabric) is made with warp and weft threads and then additional pile warp threads are arranged to form piles or tufts on the fabric surface. More specifically, the terry fabric means a warp pile fabric with a multi-layer structure in which loops are formed in the lower part with a special warp, the so-called terry pile.

Hereinafter, a multi-ply towel and a method for producing the same according to the present invention will be described in detail.

The present invention provides a multi-ply towel, and the multi-ply towel according to the present invention is obtained by first winding ground warp threads and pile threads on separate beams respectively and then setting the ground warp threads with strong tension and the pile threads with weak tension in a weaving machine equipped with a weft beating device. In this case, the ground warp threads and the pile threads are arranged alternately. The multi-ply towel comprises a terry fabric in which loops are formed on both surfaces of a base by inserting a first weft thread between the warp threads, shooting the first weft thread, inserting a second weft thread between the warp threads and then shooting the second weft thread so strongly that the pile warp threads are pushed forward.

The terry cloth can be dyed in different patterns by subjecting it to primary dyeing with a disperse dye and secondary dyeing with a reactive dye.

The lower part (ground fabric) may be formed by weaving ground warp threads and weft threads. The ground warp threads and the weft threads may contain cotton fibers, and the ground warp threads and the weft threads may be cotton spun fiber threads produced by a usual cotton spun fiber spinning process using cotton fibers. A fineness of the cotton spun fiber thread may be a cotton yarn number of 20 to 40. The use of the cotton spun fiber thread having the above fineness is preferable for ensuring the weavability and mechanical strength for producing the multi-ply towel, the dimensional stability of the produced multi-ply towel, and the excellent absorbency of the multi-ply towel.

The pile threads may comprise a first pile thread and a second pile thread.

The first pile thread may contain cellulosic fibers, and the cellulosic fibers may comprise one or more fibers selected from the group consisting of cotton fibers, hemp fibers, rayon fibers, lyocell fibers, and blended yarn of polynosic fibers and cotton fibers. The cotton fibers or lyocell fibers may be included for dimensional stability, absorbency, and dyeing in various patterns of the multi-ply towel. The first pile thread may be a spun fiber thread containing cellulosic fibers, and the spun fiber thread may have been subjected to a conventional spinning process.

The second pile thread may include one or more threads selected from the group consisting of a blended yarn of polyester fibers and cotton fibers, a blended yarn of polyester fibers and regenerated cellulose fibers, and a polyester yarn, and splittable nylon/polyester composite fibers. The second pile thread may include a blended yarn of polyester fibers and cotton fibers and splittable nylon/polyester composite fibers for absorbency, softness, and dyeing in various patterns of the multi-ply towel.

The blended yarn of polyester fiber and cotton fiber may be a spun yarn obtained by blending 70 to 80 wt% of polyester fiber and 30 to 20 wt% of cotton fiber and subjected to a co-spinning process. The blended yarn of polyester fiber and cotton fiber may contain, but is not limited to, 70 wt% of polyester fiber and 30 wt% of cotton fiber for absorbency and dyeing in various patterns of the multi-ply towel.

The weight ratio of nylon to polyester in the splittable nylon/polyester microfibers can be 2:8 to 3:7. The microfibers can be formed by ultra-refining in a splitting process, and the splitting process may be carried out during the dyeing process. The splitting process is carried out by reducing the weight of polyester in the splittable nylon/polyester composite fibers. The reduced weight of the polyester may be 5 to 7 wt%, and if the reduced weight of the polyester exceeds 7 wt%, the strength of the microfibers may be reduced.

A common weight reduction process can be used for the weight reduction process. For example, an alkaline weight reduction process can be used, but the weight reduction process is not limited to this. It is preferable that alkali dissolution is minimized to prevent dissolution of components other than eluting resin in terms of the strength of the fiber.

The splittable nylon/polyester microfibers consist of 30 to 70 filaments and undergo ultra-refining to achieve a thickness of 0.01 to 1 denier/filament by splitting filament threads with a total fineness of 40 to 100 denier. Since fine gaps are formed between the fibers after the splitting process, an area of the fibers is increased and thus a water absorption capacity is greatly increased.

The blended yarn of polyester fibers and cotton fibers can have a primary twist of 300 to 500 TPM. The primary twist can be an S-twist or a Z-twist.

After the primary twist, a high-pressure steam treatment is performed to fix the twist. The fixed blended yarn of polyester fiber and cotton fiber is subjected to a untwisting process. The blended yarn that has undergone the untwisting process has a secondary twist in a direction opposite to the direction of the primary twist. For example, when the primary twist is in the S direction, the secondary twist is adjusted to be in the Z direction, and when the primary twist is a Z twist, the secondary twist is adjusted to be an S twist.

The splittable nylon/polyester microfibers can have the same primary twist and secondary twist as those of the blended yarn made of polyester fibers and cotton fibers.

The second pile yarn may have a tertiary twist obtained by combining and twisting the blended yarn of polyester fibers and cotton fibers and the splittable nylon/polyester microfibers with the same twisting direction and number of twists in the same direction. The blended yarn of polyester fibers and cotton fibers and the splittable nylon/polyester microfibers are formed into a strand shape when they are combined and twisted. That is, a strand comprising the blended yarn of polyester fibers and cotton fibers and the splittable nylon/polyester microfibers can be obtained.

A number of rotations of the primary rotation (T1) may be greater than a number of rotations of the secondary rotation (T2) and the number of rotations of the secondary rotation (T2) may be greater than a number of rotations of the tertiary rotation (T3).

(wobei T1 die Anzahl von Drehungen der Primärdrehung darstellt und T2 die Anzahl von Drehungen der Sekundärdrehung darstellt).The primary rotation and the secondary rotation can satisfy the following expression 1:
[Expression 1]
$$0.5\le \text{T2}/\text{T1}<1$$

(where T1 represents the number of turns of the primary rotation and T2 represents the number of turns of the secondary rotation).

T2/T1 can be 0.8 or less, and when 0.5 ≤ T2/T1 ≤ 0.7, a fixed curl shape of the primary twist can be maintained at 80% or more.

(wobei T1 die Anzahl von Drehungen der Primärdrehung darstellt und T3 die Anzahl von Drehungen der Tertiärdrehung darstellt).The primary rotation and the tertiary rotation can satisfy the following expression 2:
[Expression 2]
$$0.005\le \text{T3}/\text{T1}\le \text{0}\text{,09}$$

(where T1 represents the number of turns of the primary rotation and T3 represents the number of turns of the tertiary rotation).

T3/T1 may preferably be 0.01 or more and 0.05 or less, and when T3/T1 is 0.01 or more and 0.02 or less, a curl shape of the primary twist and the secondary twist can be maintained at 80% or more.

When T2/T1 and T3/T1 satisfy the above numerical ranges, rotational voids or rotational grooves are formed in a vertical direction of the pile threads, so that moisture can be absorbed or removed by only the pile threads. The pile threads satisfying the above numerical ranges are difficult to leak out of the weave structure of the terry cloth, so that the shape can be maintained even after repeated washing when the multi-layer towel is used. Therefore, the pile threads can solve the problem that the towel looks white due to repeated washing and rubbing in use. In addition, the absorption rate of the multi-layer towel made by using the terry cloth with the pile threads satisfying the above numerical ranges can be 40 to 60% or 45 to 55%.

In a method for producing a multi-layered towel according to the present invention, first, ground warp threads which are cotton staple fibers, a first pile thread and a second pile thread which is a tertiary twisted strand are wound on separate beams, respectively, and then, in a weaving machine equipped with a weft beating device, the ground warp threads are inserted with strong tension and the first and second pile threads are inserted with weak tension. In this case, the ground warp thread and the first pile thread are arranged side by side, and the ground warp thread and the second pile thread are arranged side by side to arrange the ground warp threads and the pile threads alternately. The method comprises: producing a terry fabric by inserting a first weft thread between the warp threads, shooting the first weft thread, inserting a second weft thread between the warp threads and then shooting the second weft thread so tightly that the first and second pile threads are pushed forward to form loops on both surfaces of a base having a front surface on which loops are formed by the first pile thread and a back surface on which loops are formed by the second pile thread, and dyeing the produced terry fabric.

Since the components used as materials for the ground warp thread, weft thread and pile threads are the same as described above, the specific details thereof are omitted.

The method may further comprise twisting the pile yarns prior to producing the terry fabric, and the twisting may comprise a primary twisting process, a secondary twisting process and a tertiary twisting process.

In the primary twisting process, a blended yarn of polyester fibers and cotton fibers and splittable nylon/polyester microfibers may be twisted to have an S twist or a Z twist of 300 to 500 TPM. When the above number of twists is maintained, rotation voids or rotation grooves are easily formed in a vertical direction of the second pile yarn, so that the strength of the second pile yarn can be maintained.

The method may further comprise performing a high-pressure steam treatment after the primary twisting process to fix the twist. In the high-pressure steam treatment, any device capable of performing a high-pressure steam treatment can be used without limitation, and the high-pressure steam treatment is preferably performed at a temperature of 130 to 150°C for a time not exceeding 10 minutes at most. If the temperature in the high-pressure steam treatment exceeds 150°C, thermal deformation of the polyester and cotton fiber blend yarn and the splittable nylon/polyester microfibers may occur, which may cause a reduction in strength. If the time for the high-pressure steam treatment exceeds 10 minutes, excessive shrinkage of the fibers will occur, which may cause an uneven appearance of the final product.

After the twisting shape is fixed, a untwisting process is carried out to untwist the blended yarn of polyester fibers and cotton fibers and the nylon/polyester fibers. After the untwisting process, a secondary twisting process is carried out to twist the blended yarn of polyester fibers and cotton fibers. sers and the splittable nylon/polyester microfibers is carried out in a direction opposite to a direction in the primary twisting process. In this case, the secondary twisting process is carried out so that a curl shape of the fixed twist is maintained at 80% or more. If a tension is applied in the secondary twisting process to maintain less than 80% of the curl shape, the curl disappears from the filament yarn, so that the water absorption and water removal capabilities are reduced.

(wobei T1 die Anzahl von Drehungen in dem primären Drehprozess darstellt und T2 die Anzahl von Drehungen in dem sekundären Drehprozess darstellt).The secondary twist in the secondary twisting process is formed by twisting the blended yarn of polyester fibers and cotton fibers and the splittable nylon/polyester microfibers in a direction opposite to a direction of the twist formed in the primary twisting process. The number of twists in the secondary twisting process may be smaller than that in the primary twisting process and may satisfy the following expression 3:
[Expression 3]
$$0.5\le \text{T2}/\text{T1}<1$$

(where T1 represents the number of rotations in the primary rotation process and T2 represents the number of rotations in the secondary rotation process).

T2/T1 can be 0.8 or less, and when 0.5 ≤ T2/T1 ≤ 0.7, a fixed curl shape of the primary twist can be maintained at 80% or more.

The primary twisting process and the secondary twisting process are carried out for the blended yarn of polyester fibers and cotton fibers and the splittable nylon/polyester microfibers, respectively.

The blended yarn of polyester fibers and cotton fibers and the splittable nylon/polyester microfibers subjected to the secondary twisting process are combined and subjected to a tertiary twisting process in the same direction as that in the primary twisting process.

A number of rotations in the tertiary rotation process may be less than the number of rotations in the secondary rotation process and may be less than the number of rotations in the primary rotation process.

(wobei T1 die Anzahl von Drehungen bei dem primären Drehprozess darstellt und T3 die Anzahl von Drehungen bei dem tertiären Drehprozess darstellt).The tertiary turning process can be performed to satisfy the following expression 4:
[Expression 4]
$$0.005\le \text{T3}/\text{T1}\le \text{0}\text{,09}$$

(where T1 represents the number of rotations in the primary rotation process and T3 represents the number of rotations in the tertiary rotation process).

When T2/T1 and T3/T1 satisfy the above numerical ranges, rotational voids or rotational grooves are formed in a vertical direction of the pile threads, so that moisture can be absorbed or removed by only the pile threads. The pile threads satisfying the above numerical ranges are difficult to leak out of the weave structure of the terry cloth, so that the shape can be maintained even after repeated washing when the multi-layer towel is used. Therefore, the pile threads can solve the problem that the towel looks white due to repeated washing and rubbing in use. In addition, the absorption rate of the multi-layer towel made by using the terry cloth containing the pile threads satisfying the above numerical ranges can be 40 to 60% or 45 to 55%.

After the terry fabric is produced, the second pile thread is primarily dyed. The dye used in the primary dyeing is not limited as long as it can dye the splittable nylon/polyester composite fibers contained in the second pile thread. It is preferable to use a disperse dye in view of the fastness of the multi-layer towel. Since a disperse dye is usually insoluble or difficult to dissolve in water, when the disperse dye is used in the primary dyeing, a pretreatment may be carried out to promote dyeing. In the pretreatment, a pretreatment solution prepared by mixing dye water with a Agent is obtained which contains a rinsing agent, a carrier, a dispersant and a leveling agent. The dyeing water is purified water and preferably has a water hardness of 30 to 100 ppm, but is not limited thereto.

The rinsing agent is used to remove various contaminants adhering to the fiber surface, and a nonionic activator such as polyoxyalkylene alkyl ether or a mixture of the nonionic activator and an anionic activator such as an alkylbenzenesulfonic acid salt or a sulfuric acid ester salt of an aliphatic alcohol is preferably used.

The dispersant is an agent for removing various contaminants adhering to the fiber surface. Preferably, an aqueous dispersant such as a sodium naphthalenesulfonate-formalin condensate, sodium alkylnaphthalenesulfonate or a condensate thereof, a formalin condensate of sodium phenolsulfonate and sodium naphtholsulfonate, sodium alkyldiphenyl ether disulfonate, sodium ligninsulfonate, polyoxyethylene alkylallyl ether which is a nonionic surfactant, a mixture of a nonionic surfactant and an anionic surfactant, a sulfonated nonionic surfactant, sodium polyacrylate, an olefin-sodium maleate copolymer, a condensed phosphate or carboxymethyl cellulose; and a non-aqueous dispersant such as alkylbenzene naphthalene sulfonate, sodium dioctyl sulfone maleate, a partially amidated or partially esterified product of a styrene-maleic anhydride copolymer, a fatty acid amide, polyoxyethylene alkylamine, alkylamine acetate or fatty acid salt, a secondary (tertiary) alkylamine or amide, or alkylimidazoline.

The carrier serves to increase the water solubility of the fiber by a swelling action that relaxes a fiber structure forming the ground warp threads, the weft threads, and the first and second pile threads. In addition, when a general disperse dye is used, the temperature of the dye solution varies depending on the kind of the fiber, but dyeing is usually carried out at 120°C or higher because at the above temperature or higher, voids are formed in the fibers and the dye can penetrate into these voids. However, in a case where a carrier as in the present invention is used, there is an advantage that the dyeing process is effectively carried out although less energy is consumed.

As a carrier that can be used in the present invention, it is preferable to use trichlorobenzene, methylnaphthalene, ortho-phenylphenol, N,N-dimethyl sulfoxide, N-methyl-2-pyrrolidone or the like.

The retarding agent is an agent that inhibits rapid dyeing to prevent color offset in the primary dyeing, and sodium sulfate, sodium chloride, sodium carbonate or the like is preferably used.

In addition, the pretreatment solution may further contain an acid and the acid serves to further lower a pH value of the pretreatment solution in order to improve the color of the dye. An acid commonly used in industry can be used as the acid.

The pretreatment solution preferably contains 1 to 2 wt.% of a rinsing agent, 0.1 to 1 wt.% of a carrier, 0.1 to 1 wt.% of a dispersant, 1 to 2 wt.% of a leveling agent and a balance of water, and preferably further contains 0.01 to 0.1 wt.% of an acid.

If the pretreatment is carried out by immersing the terry cloth in a bath containing the pretreatment solution at 90 to 110°C, and preferably 95 to 100°C, for 10 to 30 minutes, the threads can be shrunk and the penetration of the disperse dye can be promoted, which is preferable.

As a dyeing method in the primary dyeing, any dyeing method known in the related art may be used, but is not limited thereto.

The disperse dye is a dye containing one or more chromophores, and an azo dye, an anthraquinone dye, a quinophthalone dye, a naphthalimide dye, a naphthoquinone dye, a nitro dye and the like can be used. Examples of disperse dyes include CI Dispersion Yellow 3, CI Dispersion Yellow 5, CI Dispersion Yellow 64, CI Dispersion Yellow 160, CI Dispersion Yellow 211, CI Dispersion Yellow 241, CI Dispersion Orange 29, CI Dispersion Orange 44, CI Dispersion Orange 56, CI Dispersion Red 60, CI Dispersion Red 72, CI Dispersion Red 82, CI Dispersion Red 388, CI Dispersion Blue 79, CI Dispersion Blue 165, CI Dispersion Blue 366, CI Dispersion Blue 148, CI Dispersion Violet 28, and CI Dispersion Green 9.

Furthermore, the disperse dye can be selected from an appropriate database (e.g., "Color Index"). Details or further examples of the disperse dye are described on pages 133 to 158 of "Industrial Dyes" edited by Klaus Hunger, Wiley-VCH, Weinheim, 2003. Therefore, the selection can be made by referring thereto. Furthermore, two or more kinds of disperse dyes can be used in combination.

Furthermore, in order to provide other functions, an additive such as an antioxidant, a pH adjuster, a surface tension reducer, a thickener, a humectant, a color deepening agent, a preservative, an antifungal agent, an antistatic agent, a sequestering agent or a reduction inhibitor may be used in addition to the disperse dye in a primary dye solution composition.

The primary dye solution composition preferably contains 1 to 3 wt.% of a disperse dye, 1 to 5 wt.% of an additive and the balance water.

When primary dyeing is carried out at 90 to 110°C, preferably at 95 to 100°C, and most preferably at 96 to 98°C, dyeing is carried out more uniformly and fastness is improved, which is preferable because a core thread in the pile threads is shrunk and an irregular part of the filament constituting the core thread is expanded by the support. In addition, when primary dyeing is carried out for 1 to 2 hours, uniform dyeing is carried out, which is preferable.

After primary dyeing, the dye solution is removed from the bath, and rinsing and bleaching are carried out directly in the same bath. Rinsing and bleaching are common processes for the fibers constituting the ground part and the fibers constituting the pile warp threads, and by rinsing and bleaching, foreign substances and an unabsorbed dye can be removed and the absorbency can be improved.

The disperse dye is a dye containing one or more chromophores, and an azo dye, an anthraquinone dye, a quinophthalone dye, a naphthalimide dye, a naphthoquinone dye, a nitro dye, and the like can be used. Examples of disperse dyes include C.I. Disperse Yellow 3, C.I. Disperse Yellow 5, C.I. Disperse Yellow 64, C.I. Disperse Yellow 160, C.I. Disperse Yellow 211, C.I. Disperse Yellow 241, C.I. Disperse Orange 29, C.I. Disperse Orange 44, C.I. Disperse Orange 56, C.I. Disperse Red 60, C.I. Disperse Red 72, C.I. Disperse Red 82, C.I. Dispersion Red 388, C.I. Dispersion Blue 79, C.I. Dispersion Blue 165, C.I. Dispersion Blue 366, C.I. Dispersion Blue 148, C.I. Dispersion Violet 28, and C.I. Dispersion Green 9.

In addition, the disperse dye can be selected from an appropriate database (e.g., "Color Index"). Details or other examples of disperse dyes are described on pages 133 to 158 of "Industrial Dyes" edited by Klaus Hunger, Wiley-VCH, Weinheim, 2003. Therefore, the selection can be made by referring thereto. In addition, two or more kinds of disperse dyes can also be used in combination.

Furthermore, in order to provide further functions, an additive such as an antioxidant, a pH adjuster, a surface tension reducer, a thickener, a humectant, a color deepening agent, a preservative, an antifungal agent, an antistatic agent, a sequestering agent or a reduction inhibitor may be used in addition to the disperse dye in a primary dye solution composition.

The primary dye solution composition preferably contains 1 to 3 wt.% of a disperse dye, 1 to 5 wt.% of an additive and water as a balance.

When primary dyeing is carried out at 90 to 110°C, preferably at 95 to 100°C, and most preferably at 96 to 98°C, dyeing is carried out more uniformly and fastness is improved because a core thread in the pile threads is shrunk and an irregular part of the filament constituting the core thread is expanded by the support, which is preferable. In addition, when primary dyeing is carried out for 1 to 2 hours, uniform dyeing is achieved, which is preferable.

As the rinsing agent used in rinsing and bleaching, an inorganic rinsing agent or an organic rinsing agent commonly used in the art can be used, and preferably sodium hydroxide (NaOH), sodium carbonate (Na ₂ CO ₃ ), sodium bicarbonate (NaHCO ₃ ), sodium sesquicarbonate (Na ₂ CO ₃ NHCO ₃ 2H ₂ O), sodium silicate (xNa ₂ Si ₄ O ₉ + yNa ₂ Si ₂ O ₃ + zH ₂ O), calcium oxide (CaO), calcium hydroxide (Ca(OH) ₂ ) or the like is used.

A bleaching agent used in rinsing and bleaching acts to decompose dyes by an oxidation-reduction process, and for example, a chlorine-based bleaching agent such as bleaching powder (Ca(OCl) ₂ ), sodium hypochlorite (NaClO) or sodium chlorite (NaClO ₂ ), a peroxide-based bleaching agent such as hydrogen peroxide (H ₂ O ₂ ), sodium peroxide (Na ₂ O ₂ ), sodium perborate (NaBO ₃ .4H ₂ O) or potassium permanganate (KMnO ₄ ), or a sulfurous acid-based bleaching agent such as sulfurous acid gas (SO ₂ ), sodium bisulfite (NaHSO ₃ ) or sodium hydrosulfite (Na ₂ S ₂ O ₄ ) is preferably used.

In addition, a chelating agent such as an aminopolycarboxylic acid (ethylenediaminetetraacetic acid (EDTA)), a hydroxypolycarboxylic acid (citric acid), aminomethylphosphonic acid (ethylenediaminetetramethylphosphonic acid (EDTMP)), a polycarboxylic acid (oxalic acid) or sodium hexametaphosphate, or a stabilizer such as a polysilicate or a polyacrylate may be added to a treating solution composition used in rinsing and bleaching.

The rinsing and bleaching is carried out at 90 to 98°C, preferably at 95 to 98°C, and particularly preferably at 96 to 98°C. If the temperature is outside the above range, the foreign substances and the unabsorbed dye cannot be sufficiently removed, and the core thread dyed by the primary dyeing may be discolored.

The treating solution composition preferably contains 1 to 5 wt.% of a rinsing agent, 1 to 5 wt.% of a bleaching agent, 0.1 to 5 wt.% of an additive and the balance water.

After rinsing and bleaching, secondary dyeing is carried out.

The secondary dyeing can be carried out in the same bath by only changing the treating solution as in the rinsing and bleaching. In particular, in the method for producing a multi-ply towel according to the present invention, after the second pile yarn is dyed with a disperse dye in the primary dyeing, a residue of the disperse dye is discharged through a rinsing process using sodium hydroxide, a dyeing process suitable for cellulose fibers, and a variety of post-treatment processes, so that the fastness of the second pile yarn can be increased.

In the secondary dyeing, the ground warp yarns, the weft yarns, and the first pile yarn are dyed, preferably using a dyeing method and a dye for cellulose fibers. For example, it is desirable to use one or two or more dyes selected from a direct dye, a sulfur dye, a vat dye, an azo dye, an acid dye, a basic dye, and a reactive dye, and a reactive dye is preferably used as the dye used in the secondary dyeing in view of the fastness of the multi-ply towel, but the type of the reactive dye is not limited as long as it is a reactive dye that can be used in dyeing by a dyeing method to be used, such as a dip dyeing method, a cold pad batch (CPB) dyeing method, or a continuous dyeing method.

The reactive dye is composed of a chromogen and a reactive group, and generally the same reactive group has a property that an adsorption rate varies greatly depending on a molecular structure of the chromogen. Therefore, it is desirable to use a reactive dye obtained by combining a chromogen having excellent fastness with a specific reactive group. It is desirable to use a reactive dye containing two or more functional groups rather than a reactive dye having a monofunctional group because it can prevent the phenomenon that the towel looks white due to friction generated during use and repeated washing.

As the reactive group, a vinylsulfone-based or triazine-based reactor is preferable because it is inexpensive, is not limited to one dyeing method, forms a stable bond between the fibers and the reactive dye, and has excellent fastness and uniformity.

As the reactive dye used in the present invention, for example, Lanasol CE, Yellow light, Orange light, Blue light, Navy light, Red light, Rose light, Lemon light, Sky light, Cibacron FN, Red FN-3G, Red FN-G, and Cibacron LS manufactured by CIBA Specialty Chemicals; Blue P-NFB liquid 50, yellow P-N3R liquid 33, and Red P-4BN liquid 25 manufactured by NIPPON KAYAKU Co, Ltd; Sumifix HF type manufactured by Sumitomo Chemical Co. Ltd; Sirius plus, Realan and Reanova CA manufactured by DyStar; Remazol RU-N manufactured by Hoechst Mitsubishi Kasei Co. Ltd; Procion CX manufactured by Zeneca Group PLC; Optizal-based dyes manufactured by Clariant AG; and the like can be used. All of these dyes have a high fixing rate of 80% or more and excellent wet fastness and are suitable for the present invention. Two kinds of reactive dyes can also be used in combination.

One or more dyes are selected from the reactive dyes described above, and the amounts of the auxiliary agent and dye to be used are determined according to a degree of darkness of the color even when a method is selected from a dip dyeing method, a CPB dyeing method and a continuous dyeing method. Then, an alkaline auxiliary solution containing 5 to 10 g/L of sodium carbonate and 80 to 120 g/L of sodium silicate can be prepared, and a dye solution can be prepared by mixing 10 to 30 g/L of the reactive dye and distilled water. In this case, the sodium silicate serves as a buffer that adjusts the pH of the dye solution to a constant value and reduces a difference in color concentration of the fabric. A medium color tone can be reproduced using a secondary dye solution composition containing the auxiliary solution and the dye solution in a volume ratio of 4:1.

When dyeing a fabric in a dark color (hue), 30 g/L or more of the reactive dye, 80 to 120 g/L of sodium silicate and 10 to 20 g/L of sodium carbonate can be used. The auxiliary solution containing sodium silicate and sodium and the dye solution prepared by dissolving the reactive dye in distilled water can be used in amounts where the volume ratio (auxiliary solution:dye solution) is 4:1.

The terry cloth fabric is immersed in a dye solution composition at 50 to 90 °C for 1 hour or more so that the reactive dye can be fixed to the ground warp threads, the weft threads and the first pile thread of the terry cloth fabric.

If an unfixed dye remains in the terry cloth for 1 hour or more, the fastness of the multi-layer towel deteriorates. In order to decompose and remove the unfixed dye and also to form a covalent bond between the fiber and the reactive dye fixed to the fiber, the terry cloth after dyeing is immersed in a 5 to 10 wt% sodium hydroxide aqueous solution at 90°C for 1 to 10 minutes or 3 to 7 minutes, washed with running water to remove sodium carbonate and sodium hydroxide, and then dried at 100 to 130°C for 60 to 90 seconds, thereby completing the secondary dyeing.

The composition of the secondary dye solution may also contain a mordant and a rinsing agent.

The mordant serves to promote color development and to attach the dye to the fiber. Preferably, an aluminum mordant such as alum (potassium aluminum sulfate, AlK(SO ₄ ) ₂ ·12H ₂ O), aluminum acetate or aluminum chloride, a copper mordant such as copper acetate or copper sulfate, or a sodium mordant such as sodium sulfate anhydrous (sodium sulfate) is used, but the mordant is not limited to these, and any mordant can be used as long as it is commonly used by those skilled in the art.

The rinse agent serves to remove impurities so that the dye can be well adsorbed by the fiber. It is desirable to select one or a mixture of two or more from the group consisting of alkyl sulfate, alkyl phosphate, alkyl sulfonate, alkyl polyoxyethylene ether sulfonate and alkyl polyoxyethylene ether phosphate, but the rinse agent is not limited thereto.

The mordant and the rinsing agent may be present in the secondary dye solution composition in amounts of 1 to 5 wt% and 1 to 5 wt%, respectively.

After secondary dyeing, a soaping process can also be carried out.

The soaping process is a process for removing an unfixed dye remaining after dyeing and is preferably carried out at a temperature of 90 to 110°C for 20 minutes to 1 hour.

A soap solution composition used in the soaping process can be prepared by adding a soaping agent to ordinary water having the above temperature, and it is recommendable to use PROTEPON RSA or PROTEPON NRC manufactured by Protex Korea Co, Ltd or the like as the soaping agent, but the soaping agent is not limited to this. When the soaping agent is added in an amount of 1 to 5 g based on 1 L of water, reattachment of impurities is prevented while blocking of metal ions is maintained, so that the fastness of the dye can be increased, which is desirable.

After the soaping process, the soap solution composition is removed from the bath, and a softening treatment may be further carried out in the same bath. The softening treatment is carried out to impart elasticity, smoothness, fluffiness and softness to a towel to be produced, and the softening treatment may be carried out by a method conventional in the art. In addition, the softening treatment is preferably carried out with a softening solution composition at 20 to 60°C for 10 to 60 minutes.

Any plasticizer can be used in the plasticizing solution composition as long as it is commonly used in the art. As the plasticizer, for example, CSE-920 manufactured by CHEONG SAN CHEM TECH Co., Ltd. can be used, but is not limited to it, and is preferably added in an amount of 1 to 5% based on the over weight of fiber (owf).

After the softening treatment is finished, the treatment solution, moisture and the like remaining in the terry cloth are removed by water washing and drying processes, and then the terry cloth is cut according to the sales conditions, so that a towel according to the present invention can be manufactured.

After the dyeing is finished, a process of attaching a herbal medicinal extract can be further carried out.

As the herbal medicine extract according to the present invention, one or a mixture of two or more of Schisandra Chinensis, Coptis Chinensis, Houttuynia Cordata, Anemarrhena Asphodeloides, Taraxaci Herba, Peony, Forsythiae Fructus, and Honeysuckle can be used. These herbal medicines can impart a unique natural fragrance to the produced towel and can minimize skin irritation. In addition, they can produce a stronger antibacterial effect in combination with the antibacterial effect of bamboo fiber.

As an extraction method of the herbal medicinal extract, a usual method can be used, and for example, a herbal medicinal extract can be extracted by heating or using a solvent and can be used after being concentrated if necessary.

It is preferable to use a binder to attach the herbal medicinal extract to the fiber surface. The binder is hydrophilic and is not specifically limited as long as it does not greatly affect the physical properties of the towel to be produced.

As the binder, a polycarboxylic acid such as an aliphatic polycarboxylic acid, an alicyclic polycarboxylic acid, an aromatic polycarboxylic acid, a saturated aliphatic dicarboxylic acid, an unsaturated aliphatic dicarboxylic acid, an aromatic dicarboxylic acid or an alicyclic dicarboxylic acid; or a glycol polymer such as polyethylene glycol or polypropylene glycol is preferably used.

As an attachment method for the herbal medicinal extract, a conventional method that can be used in the art, for example, a dipping method, a spraying method, a coating method or the like, can be used, and a dipping method is preferably used.

The herbal medicinal extract and the binder may be attached in the form of a liquid containing a solvent, and in this case, the herbal medicinal extract and the binder may be added in amounts of 1 to 10% and 5 to 20% owf, respectively. In addition, as the solvent, a common solvent capable of dissolving all of the binder and the herbal medicinal extract may be used, but is not limited to this.

After the treatment as described above is completed, the moisture that may remain in the terry cloth is removed, and then the terry cloth is cut into different sizes according to the sales conditions, so that a multi-layer towel is produced.

Below, the physical properties in an example and comparative examples were measured as follows.

Example 1

Production of ground warp threads and pile threads

After an S-twist of 300 TPM was applied to 45D/30F N/P splittable microfibers, the S-twisted N/P splittable microfibers were treated with high pressure steam at a temperature of 130°C for 5 minutes and then untwisted. A Z-twist of 180 TPM was applied by applying a tension so that a curl shape of the twist was maintained at 80%.

After an S-twist of 300 TPM was applied to a blended yarn of polyester fibers and cotton fibers containing 70 wt% of polyester fibers and 30 wt% of cotton fibers, the S-twisted blended yarn was treated with high pressure steam at a temperature of 130°C for 5 minutes and then untwisted. A Z-twist of 180 TPM was made by applying a tension so that a curl shape of the twist was maintained at 80%.

An S-twist of 5 TPM was applied to each of the splittable N/P microfibers to which the secondary twist was applied and to the blended yarn of polyester fibers and cotton fibers to which the secondary twist was applied to form a strand, thereby preparing a second pile yarn.

Cotton spun threads, which have a cotton yarn count of 30 and contain 100% cotton fibres, were manufactured and used as ground warp threads, weft threads and a first pile thread.

Making a terry cloth

The ground warp threads, the first pile thread, and the second pile thread were each wound on separate beams, and then the ground warp thread and the first pile thread, and the ground warp thread and the second pile thread were arranged alternately. In a loom equipped with a weft beating device, the ground warp threads were inserted with strong tension and the pile threads with weak tension. A terry fabric was formed with loops on both surfaces of a ground piece by inserting a first weft thread between the ground warp threads, shooting the first weft thread, inserting a second weft thread between the ground warp threads, and then violently shooting the second weft thread so that the pile threads were advanced.

Primary dyeing

A primary dye solution composition composed of 3 wt% of a disperse dye (C.I. Disperse Red 60, LG Chem Ltd.), 1 wt% of a carrier (trichlorobenzene) and 98 wt% of water was prepared. The woven terry cloth was added to the primary dye solution composition and primary dyeing was carried out at 98°C for 1 hour.

After the primary dye solution composition was removed from the bath, a rinsing and bleaching treatment solution was immediately added, and then the primary dyed terry cloth was subjected to rinsing and bleaching without washing with water. At this time, the temperature of the treatment solution was 98°C, the treatment time was 30 minutes, and the treatment solution consisted of 1% by weight of a detergent (sodium hydroxide), 1% by weight of a bleaching agent (sodium hypochlorite) and 98% water.

Secondary dyeing

After rinsing and bleaching were completed, the treatment solution was drained from the bath, a secondary dye solution composition was added to the bath, and then secondary dyeing was carried out. At this time, a dye solution in the secondary dye solution composition was prepared by mixing 10 g of a reactive dye (Lanasol CE, CIAB Specialty Chemicals) and distilled water so that a concentration of 10 g/L was achieved.

An alkaline auxiliary solution containing 7 g/L of sodium carbonate and 80 g/L of sodium silicate was prepared, and then the alkaline auxiliary solution and the dye solution were mixed so that the volume ratio was 4:1, thereby preparing a dye solution composition. The terry cloth was immersed in the dye solution composition at 60°C for 1 hour to conduct secondary dyeing. The terry cloth was taken out from the dye bath, and water was then removed. The terry cloth from which the water had been removed was immersed in a 10 wt% sodium hydroxide solution for 7 minutes. At this time, the temperature of the sodium hydroxide solution was adjusted to 90°C. The terry cloth taken out from the sodium hydroxide solution was washed with running water for 10 minutes or more. After the water was removed from the washed terry cloth, a soap solution containing 1 wt% of a soaping agent (PROTEPON RSA, Protex Korea Co., Ltd.) was added and a soaping process was carried out at 98°C for 30 minutes.

After the soaping process was completed, the soap solution was removed, and then a softening solution to which a softener (CSE-920, CHEONG SAN CHEM TECH Co., Ltd.) was added in an amount of 1% owf was added, and softening was carried out at 40°C for 30 minutes. After the softening process was completed, the terry cloth was sufficiently washed with water and dried to prepare a sample. The softness, fastness and absorption rate of the sample were measured. The results of which are shown in Table 1.

The multi-layer towel produced after all the processes has a pattern divided into an area represented by a reactive dye and an area represented by a disperse dye, as shown in 1 shown.

Comparison example 1

The same procedures were carried out in the same manner as in Example 1 except that a tertiary rotation of 15 TPM was applied.

Comparison example 2

The same procedures were carried out in the same manner as in Example 1 except that a tertiary rotation of 1 TPM was applied.

Comparison example 3

The same procedures were carried out in the same manner as in Example 1, except that pile yarns consisting only of splittable nylon/polyester microfibers (ultrafine unit of 60D/72F) were used instead of the first and second pile yarns.

1. Absorption rate test

The absorption rates of the terry cloth fabrics produced in the example and the comparative examples were measured according to the method KS K 0815.

2. Test of authenticity

The wash fastness was measured according to the method KS K 0430.

The rub fastness was measured according to the method KS K 0650. [Table 1] Entries Example 1 Comparison example 1 Comparison example 2 Comparison example 3 Absorption rate (%) 47 35 32 28 Wash fastness pollution Cotton 5 4 4 3-4 PET 5 4 4 3-4 Wool 5 4 4 3-4 Rub fastness Dry 5 4 4 2 Wet 5 4 4 2

As shown in Table 1, in the case where the second pile yarn satisfying Expressions 1 and 2 (or Expressions 3 and 4) was included, the absorption rate was significantly higher than that without it, and the washing fastness and the rubbing fastness were also significantly higher. Particularly, in the case of the multi-layer towel having the terry cloth containing the pile yarns composed of the nylon/polyester blended yarn, it could be found that the absorption rate, the washing fastness and the rubbing fastness were significantly lower than those in Example 1.

This is because by rotating the second pile thread three times, rotational cavities and rotational grooves are formed in the vertical direction of the fibers, thereby increasing the absorption amount and making the dye relatively easy to adsorb, so that the fiber and the dye are more firmly bonded together.

As set forth above, the multi-layer towel with excellent absorbency according to the present invention has excellent moisture absorption and moisture removal, can be dyed in various patterns, and can maintain its softness even after repeated washing.

According to the method for producing a multi-layered towel of the present invention, a multi-layered towel which is excellent in moisture absorption and moisture removal and can be dyed in various patterns can be produced, and double dyeing in one bath can be carried out without interaction between dyeing with the reactive dye and dyeing with the disperse dye. Furthermore, the dyeing processes can be simplified, which can save energy in the manufacturing process.

Although the present invention has been described above by specific matters and limited exemplary embodiments, these have been provided only to aid in the overall understanding of the present invention. Therefore, the present invention is not limited to the exemplary embodiments. Various modifications and changes can be made by those skilled in the art to which the present invention relates based on this description.

Therefore, the scope of the present invention should not be limited to the exemplary embodiments described, but the claims and all modifications that are equal or equivalent to the claims are intended to be included within the scope of the present invention.
