DETAILED DESCRIPTION

Preferred embodiments of the present invention will be described in detail with reference to the attached drawings.
FIG. 1 is a schematic sectional view illustrating an overall process for manufacturing a perspiration-absorbing, quick-drying fabric according to the present invention, FIG. 2 is a partial enlarged sectional view illustrating formation of a water repellent layer and water absorbing holes in the fabric, using Gravure rolls illustrated in FIG. 1, FIG. 3 is a sectional view of a perspiration-absorbing, quick-drying fabric which has been water repellent finished according to the present invention, and FIG. 4 is a partial enlarged view illustrating an exemplary mesh structure of a water absorbing and repelling part formed in the perspiration-absorbing, quick-drying fabric illustrated in FIG. 3.
For the convenience of description of the perspiration-absorbing, quick-drying fabric according to the embodiment of the present invention, a pre-processed perspiration-absorbing, quick-drying fabric will be referred to as a fabric body, and a processed perspiration-absorbing, quick-drying fabric will be referred to as a perspiration-absorbing, quick-drying fabric.
Referring to FIGS. 1 to 4, a perspiration-absorbing, quick-drying fabric body 20 according to an embodiment of the present invention includes a surface 52 being a first surface formed in an outward direction and a rear surface 54 being a second surface formed in an opposite direction to the first direction.
The fabric body 20 is a fabric yet to be processed for manufacturing of the perspiration-absorbing, quick-drying fabric according to the embodiment of the present invention. The perspiration-absorbing, quick-drying fabric according to the embodiment of the present invention may be finished by processing the fabric body 20 in a predetermined process described below.
The fabric body 20 may be a hydrophilic fabric, and the water absorption of the hydrophilic fabric may be maximized through hydrophilic processing of the fabric.
Further, the water absorption and water-absorbing speed of the fabric body 20 may be maximized by maximizing an electrical potential difference between a hydrophilic part and a hydrophobic part. For example, the hydrophilic fabric may be manufactured so as to have a physical water absorbing function based on the capillary phenomenon of a non-circular cross-section fiber or a chemical water absorbing function using a natural fiber having an official regain of 8%, such as cotton, wool, or rayon.
A water absorbing and repelling part 55 may be formed on the rear surface 54 through water-absorption processing of the fabric body 20. The water absorbing and repelling part 55 may include a water repellent layer 56 and water absorbing holes 58. The water repellent layer 56 may be formed according to a pattern defined by the water repellent layer 56 and the water absorbing holes 58.
The water repellent layer 56 may be formed in a fully connected mesh structure. In this case, a single water repellent layer 56 may be provided, and a plurality of water absorbing holes 58 may be provided.
Or the water absorbing holes 58 may be fully interconnected in a mesh structure according to the shape of the pattern. In this case, the water absorbing holes 58 may be fully interconnected and thus provided as a single layer, and a plurality of water repellent layers 56 may be provided.
The above-described mesh structure may be designed to be regularly or irregularly arranged.
Preferably, the water repellent layer 56 is formed to have a surface area being 50 to 97% of the total surface area of the rear surface 54, in a relationship with the water absorbing holes 58. If the surface area of the water repellent layer 56 is less than 50% of the total surface area of the rear surface 54, water may be absorbed and spread slowly through the water absorbing holes 58, thus weakening the effect of moisture elimination. On the contrary, if the surface area of the water repellent layer 56 is larger than 97% of the total surface area of the rear surface 54, it is difficult to form the mesh structure. Accordingly, it is preferred that the surface area of the water repellent layer 56 is 50 to 97% of the total surface area of the rear surface 54.
The water repellent layer 56 is embedded to a predetermined depth from the rear surface 54 toward the surface 52 of a perspiration-absorbing, quick-drying fabric 50.
For example, when the water repellent layer 56 is formed by coating a water repellent forming solution 36 using Gravure rolls 30 and 31, the fabric 20 may be pre-heated at a dry temperature of 110 to 160° C. for 10 to 40 seconds, using a fabric pre-heater 10 in order to embed the water repellent layer 56 to a predetermined depth, and the water repellent forming solution 36 may be composed of a 10 to 100 g/l water repellent agent, a 5 to 200 g/l thickener, and water as a solvent.
The water repellent agent may be, but not limited to, a fluorinated water-repellent agent. As far as it is available for formation of a water repellent layer, any water repellent agent may be used.
When the water repellent forming solution 36 used to acquire the perspiration-absorbing, quick-drying fabric 50 is coated on the rear surface of the pre-processed fabric 20, the water repellent forming solution 36 tends to be absorbed to the opposite surface from the rear surface of the pre-processed fabric 20 due to the property of water as a solvent.
Since the pre-processed fabric 20 has been pre-heated at the dry temperature of 110 to 160° C. for 10 to 40 seconds before it is provided to the Gravure rolls 30 and 31, the solvent (water) of the water repellent forming solution 36 coated on the rear surface of the pre-processed fabric 20 evaporates immediately from the lower Gravure roll 31 due to heat remaining on the fabric 20 as soon as the water repellent forming solution 36 is coated. Therefore, the perspiration-absorbing, quick-drying fabric 50 having the water repellent layer 56, which is just embedded to a predetermined depth from the rear surface 54 without spreading to the surface 52 may be acquired.
Thus, the perspiration-absorbing, quick-drying fabric 50 has the water repellent layer 56, which is just embedded to a predetermined depth from the rear surface 54 without spreading to the surface 52. After the water repellent layer 56 is processed, the water repellent layer 56 is heated at a dry temperature of 150 to 190° C. for 10 to 50 seconds in a fabric heater 40. As a result, the solvent contained in the water repellent forming solution 36 is completely evaporated and thus the stably bound water repellent layer 56 may be formed.
Herein, it is also possible to form the water repellent layer 56 through heating without performing the pre-heating.
As the water repellent layer 56 is formed by coating and embedding the water repellent agent in the above manner, the water absorbing holes 58 with no water repellent agent coated therein are formed. That is, the water absorbing holes are formed on the water repellent layer 56 formed by embedding the water repellent agent. Since the water repellent layer 56 and the water absorbing holes 58 are formed on the rear surface 54, the perspiration-absorbing, quick-drying fabric 50 has the water absorbing and repelling part 55.
Because the fabric body 20 is hydrophilic, the remaining part of the perspiration-absorbing, quick-drying fabric 50 except for the water repellent layer 56 is a hydrophilic part 60.
The method for embedding the water repellent layer 56 into the rear surface is not limited to coating using the gravure rolls 30 ad 31. Rather, any method for embedding the water repellent layer 56 may be used. That is, a water repellent layer may be embedded into the rear surface by printing based on a thermal transfer paper with a printed water repellent layer formed thereon.
A process for perspiration absorption and quick drying of the perspiration-absorbing, quick-drying fabric 50 having the above structure according to the present invention will be described below.
The perspiration-absorbing, quick-drying fabric 50 quickly absorbs moisture such as sweat generated from the skin of a wearer through the water absorbing and repelling part 55. That is, the water repellent layer 56 blocks and suppresses transfer of the moisture from the skin of the wearer to the hydrophilic part 60. That is, since moisture remains in a potential area with a low potential difference, transfer of the moisture is blocked by the water repellent layer 56.
If an outlet is provided to the blocked and suppressed moisture, the moisture gathers to the outlet. Therefore, the moisture is transferred to and absorbed in the hydrophilic part 60 through the water absorbing holes 58 faster and more efficiently than in an environment wholly opened for free moisture transfer. Once moisture is absorbed in areas where the water absorbing holes 58 are formed in the hydrophilic part 60, the moisture is then spread to the remaining part of the hydrophilic part 60. Thus, the moisture is evaporated into the air through the surface 52 of the perspiration-absorbing, quick-drying fabric 50.
As described above, the perspiration absorption and quick drying effect may be maximized because the water absorbing and repelling part 55 is provided on the rear surface 52, the water repellent layer 56 or the water absorbing holes 58 are formed in a mesh structure, and the surface areas of the water repellent layer 56 and the water absorbing holes 58 may be appropriately controlled in their relationship, in the perspiration-absorbing, quick-drying fabric 50.
In general, the diameter of a raindrop is 100 in misty rain and 3000 in a shower, whereas the molecular diameter of vapor is merely 0.004. Thus, a general water repellent finishing method is to simultaneously achieve moisture permeability and water repellency by forming a coating layer with fine holes having a diameter of about 0.1 to 10 on a surface of a fabric contacting the atmosphere.
However, since the rear surface 54 contacting the skin of a wearer is subjected to water repellent finishing in the present invention, there is no need for forming a coating layer with fine holes having a diameter of about 0.1 to 10.
The size of each of the water absorbing holes 58 formed on the perspiration-absorbing, quick-drying fabric 50 according to the present invention may be equal to or larger than the diameter of a raindrop. This is done not for the original purpose of the water repelling function for preventing introduction of external moisture such as raindrops to the skin of a wearer, but for the purpose of evaporating moisture by fast transferring and spreading the moisture from the skin to the hydrophilic part 60 in which the water repellent layer 56 is not formed.
A general water repellent layer may further be formed on the surface 52 of the perspiration-absorbing, quick-drying fabric 50. That is, in order to prevent introduction of external moisture such as raindrops, a surface water repellent layer (not shown) may be formed on the surface 52 of the perspiration-absorbing, quick-drying fabric 50. As the atmosphere-contacting surface of the fabric is additionally water repellent finished, a triple perspiration-absorbing, quick-drying fabric is obtained. In the triple perspiration-absorbing, quick-drying fabric, the water repelling function, the water absorbing and spreading function, and the water repelling and absorbing function may be simultaneously exerted on the outer surface of the perspiration-absorbing, quick-drying fabric 50, in the middle hydrophilic part 60, and on the rear surface 54, respectively.
A method for manufacturing a perspiration-absorbing, quick-drying fabric according to an embodiment of the present invention is performed as follows. First, the afore-described hydrophilic fabric 20 is pre-heated at a dry temperature of 110 to 160° C. for 10 to 40 seconds. For example, the hydrophilic fabric 20 may be pre-heated at the dry temperature of 110 to 160° C. for 10 to 40 seconds using the fabric pre-heater 10 such as a tenter.
The pre-heated pre-processed fabric 20 passes between a pair of Gravure rolls 30 and 31. As described later, the lower Gravure roll 31 has a predetermined pattern thereon to form the water absorbing and repelling part 55 (refer to FIG. 3) that includes the water repellent layer 56 and the water absorbing holes 58. The Gravure rolls 30 and 31 are used for general Gravure printing. The upper and lower Gravure rolls and 31 are brought into contact with each other and a plurality of grooves apart from each other by a predetermined interval are formed on the outer circumferential surface of the lower Gravure roll 31. Ink or a solution is accommodated in the grooves so that when an object to be printed is pressed, the ink or solution is attached to the object.
A predetermined pattern is designed on the lower Gravure roll 31. While grooves are shown as parts onto which the water repellent forming solution 36 is attached from a reservoir 34, the grooves may be replaced with protrusions. Preferably, the pattern of the water absorbing and repelling part 55 may be formed in a mesh structure.
The bottom of the lower Gravure roll 31 contacts the water repellent forming solution 36 contained in the reservoir 34 and thus the water repellent forming solution 36 is attached to the grooves of the lower Gravure roll 31. After the lower Gravure roll 31 with the attached water repellent forming solution 36 rotates a predetermined number of times, the water repellent forming solution 36 is coated on the rear surface (the bottom surface in FIG. 1) of the fabric 20.
The water repellent forming solution 36 is composed of a 10 to 100 g/l fluorinated water-repellent agent, a 5 to 200 g/l thickener, and 700 to 985 mm of water as a solvent. The thickener may be an ammoniac material, a urethane material, or an acrylic material. To enhance the tactile feeling and functions of the fabric, another additive may further be added.
The fabric water-repellent-finished by coating the water repellent forming solution 36 is dry-heated in the fabric drier 40.
The dry heating condition may be set to, but not limited to, a temperature of 150 to 190° C. and 10 to 50 seconds.
The above pre-heating step may not be performed and the water repellent layer 560 may be formed just by dry heating.
Now, a method for manufacturing a perspiration-absorbing, quick-drying fabric according to another embodiment of the present invention will be described below.
FIG. 5 is a partial enlarged sectional view of a thermal transfer paper used to manufacture a perspiration-absorbing, quick-drying fabric according to another embodiment of the present invention, and FIGS. 6A and 6B are partial enlarged sectional views illustrating an operation for manufacturing a perspiration-absorbing, quick-drying fabric using the thermal transfer paper illustrated in FIG. 5.
Referring to FIGS. 5, 6A, and 6B, a thermal transfer paper is used for a fabric body 80 having the hydrophilic property according to another embodiment of the present invention.
Printing ink is produced by decreasing the viscosity of a water repellent forming solution to 200 to 500 cps, which is composed under the same condition as for the perspiration-absorbing, quick-drying fabric according to the embodiment of the present invention, illustrated in FIGS. 1 to 4. A printed water repellent layer 76 is printed on a general transfer release paper 74 provided on a carrier sheet 72, so as to have the same porosity and pattern as described in relation to the Gravure scheme according to the foregoing embodiment of the present disclosure, and then heated at a low temperature of 40 to 90° C. In this manner, the thermal transfer paper 70 is provided.
The thermal transfer paper 70 passes between a pair of rollers 78 and 79, together with the fabric body 80. As the upper roller 78 is at 180 to 210° C., the printed water repellent layer 76 formed on the thermal transfer paper 70 is transferred to the fabric body 80 by thermal pressing.
Subsequently, the fabric having the transferred printed water repellent layer 76 passes through a heater 82, thus providing a perspiration-absorbing, quick-drying fabric 84 having a water repellent layer 83.
A detailed description will be given of methods for manufacturing a perspiration-absorbing, quick-drying fabric according to embodiments of the present invention. The embodiments are presented to describe the present invention in detail, not limiting the present invention.

Embodiment 1

In a method for manufacturing a perspiration-absorbing, quick-drying fabric, a fabric prepared before manufacturing is fabricated in a process for fabricating a general Ponte De Romma circular knitted fabric body 20. In the process for fabricating the general Ponte De Romma knitted fabric 20, for example, the fabric is woven as the Ponte De Romma knitted fabric being a circular double knit fabric using two types of yarns, that is, a rayon yarn of yarn number 30, and a nylon yarn covered with 70 denier nylon and 40 denier spandex. The shape of the fabric is stabilized by heating the fabric at 200 T for 30 seconds in a tenter, scoured, and dyed. Further, the fabric may be processed in a 20 g/l water absorbing agent solution by padding in the tenter and thermally bound at 180° C. for 30 seconds. This is an example of the hydrophilic-processed fabric. Thus, it is apparent to those skilled in the art that any general hydrophilic fabric may be used.
The above-described fabric body 20 is pre-heated by dry heat. That is, the prepared fabric body 20 is pre-heated at 130° C. for 30 seconds by operating the fabric pre-heater 10.
A water repellent forming solution is coated on one surface of the pre-heated fabric by pressure so that a coated portion and a plurality of non-coated portions at a plurality of positions may be formed. Then, the water repellent forming solution coated on the coated portion is coated even at a position apart from an opposite surface to the surface, as it is evaporated by the heat of pre-heating.
That is, a water repellent forming solution containing a 20 g/l fluorinated water-repellent agent and a 50 g/l thickener is applied to a Gravure roll having a design of a mesh structure and coated on the rear surface of the fabric. The design of a mesh structure is engraved, including mesh lines corresponding to coated and non-coated portions of the water repellent forming solution.
Therefore, the coating is performed so that when the fabric passes through the Gravure rolls, the coated portion of the water repellent forming solution may be formed as the water repellent layer 56 and the non-coated portions may be provided as the plurality of water absorbing holes 58.
The fabric coated with the water repellent forming solution is dry-heated. That is, after the water repellent forming solution is coated on the fabric, the fabric is dried at a dry temperature of 130° C. for 30 seconds in order to assure prevention of spreading of the water repellent forming solution from the rear surface 54 of the fabric to the surface 52 of the fabric. A water repellent agent may be bound on the fabric by dry-heating the fabric at 180° C. for 30 seconds in the tenter being a heater.
When a drop of distilled water was placed on a surface of the above-processed perspiration-absorbing, quick-drying fabric using a spuit, it was observed to the eyes of an observer that the water drop was sucked into the water absorbing holes 58 corresponding to non-water repellent finished parts and there was no moisture remaining on the water repellent layer 56. It was also observed that the water drop absorbed and transferred to the hydrophilic part 60 through the water absorbing holes 58 was spread fast across the whole hydrophilic part 60.
It was also observed that moisture coming out onto the surface of the perspiration-absorbing, quick-drying fabric did not permeate to the rear surface again. Although the surface was fully wet, the partially water repellent finished rear surface was dry.

Embodiment 2

After a water repellent forming solution is made of a 20 g/l water repellent agent, a 4 g/l foam surfactant, and a 3 g/l foam stabilizer, the foam water repellent forming solution is sprayed on a surface of the perspiration-absorbing, quick-drying fabric acquired in Embodiment 1, coated to a predetermined thickness on the surface of the perspiration-absorbing, quick-drying fabric by means of a blade, and thermally bound at 180° C. for 30 seconds in a tenter.
Thus, a triple perspiration-absorbing, quick-drying fabric is fabricated, in which the water repelling function occurs on the outer surface of the perspiration-absorbing, quick-drying fabric 50, the water absorbing and spreading function occurs in the middle hydrophilic part 60, and the water repelling and absorbing function occurs in the rear face 54. It was observed that when a drop of distilled water was dropped on the perspiration-absorbing, quick-drying fabric, the water drop fell down from the surface without being permeated to the rear surface. The water repellency of the center and four corners of the fabric was 100. A water drop placed on the rear surface, that is, the water repelling and absorbing part that was partially water repellent finished was sucked into the water absorbing holes being non-water repellent finished parts and thus the surface was dry.
This embodiment is intended to render a uniform of a field operator working outdoors in summer to be water repellent and anti-soil against a cool and external contamination source. A worker may not wear a thin uniform due to safety in a place like a shipyard or a construction site. Therefore, since sweat is not actively discharged, a wet uniform serves as an obstacle to activities, thus impairing safety in many cases.
With the use of the fabric with both surfaces which have been appropriately water repellent finished, introduction of a contaminant and moisture is prevented on an outer part of the fabric contacting the atmosphere, and sweat is fast discharged on a skin-contacting part of the fabric. Since the skin-contacting rear surface of the fabric is always dry without moisture, the clothes are not sticky to the body.

Embodiment 3

The same part as in the manufacturing method of Embodiment 1 will not be described herein and only the difference between Embodiment 3 and the foregoing embodiments will be described below.
A fabric prepared in the method for manufacturing a perspiration-absorbing, quick-drying fabric is knitted as a double fabric out of a polyester perspiration-absorbing, quick-drying yarn (Hyosung: AEROCOOL™ with a square fiber cross section) which is a 75 denier and 72 pillar Drawn Textured Yarn (DTY) yarn, that is, a yarn having a maximized capillary phenomenon in a circular knitting machine. After this fabric is scoured in a general method, dyed at 130° C. for 40 minutes in a common bath of a disperse dye, a dispersion leveling agent, a PH control agent, and a water absorbing agent with an owf concentration of 2.0%, cleansed, centrifugally dehydrated, and thermally bound at 180° C. for 30 seconds. Thus, a water absorption-processed fabric is fabricated. That is, Embodiment 3 is an embodiment in which a general perspiration-absorbing, quick-drying fabric is water-repellent-finished in the method for manufacturing a perspiration-absorbing, quick-drying fabric according to the present invention.
The prepared fabric is pre-heated at a dry temperature of 130° C. for 30 seconds. Subsequently, a water repellent forming solution containing a 20 g/l water repellent agent and a 50 g/l thickener is applied to a Gravure roll having a design of a mesh structure and coated on the rear surface of the fabric. The design of the mesh structure is engraved. In other words, the lines of the mesh structure correspond to parts to which the water repellent forming solution is not applied. Then, the fabric is dried at a dry temperature of 130° C. for 30 seconds in order to assure prevention of spreading of the water repellent forming solution from the rear surface of the fabric to the surface of the fabric.
A water repellent agent is bound on the fabric by dry-heating the fabric at 180° C. for 30 seconds in the tenter.
When a drop of distilled water was placed on a surface of the above-processed perspiration-absorbing, quick-drying fabric using a spuit, it was observed to the eyes of an observer that the water drop was sucked into the water absorbing holes corresponding to non-water repellent finished parts and there was no moisture remaining on the water repellent layer. It was also observed that the water drop absorbed and transferred to the hydrophilic part through the water absorbing holes was spread fast across the whole hydrophilic part. It was also observed that moisture coming out onto the surface of the perspiration-absorbing, quick-drying fabric did not permeate to the rear surface again. Although the surface was fully wet, the partially water repellent finished rear surface was dry.

Embodiment 4

The same part as in the manufacturing method of Embodiment 1 will not be described herein and only the difference between Embodiment 4 and the foregoing embodiments will be described below.
A fabric prepared in the method for manufacturing a perspiration-absorbing, quick-drying fabric is knitted as a double fabric from a general polyester perspiration-absorbing, quick-drying yarn (with a circular fiber cross section) which is a 75 denier and 72 pillar DTY yarn in a circular knitting machine. After this fabric is scoured in a general method, the fabric is dyed at 130° C. for 40 minutes in a common bath containing a disperse dye, a dispersion leveling agent, a PH control agent, and a water absorbing agent with an owf concentration of 2.0%, cleansed, centrifugally dehydrated, and thermally bound at 180° C. for 30 seconds. Thus, a water absorption-processed fabric is prepared.
The prepared fabric is pre-heated at a dry temperature of 130° C. for 30 seconds. Subsequently, a water repellent forming solution containing a 20 g/l fluorinated water-repellent agent and a 50 g/l thickener is applied to a Gravure roll having a design of a mesh structure and coated on the rear surface of the fabric.
The coating is performed so that when coated and non-coated portions of the water repellent forming solution may be formed by the Gravure rolls. Then, the fabric is dried at a dry temperature of 130° C. for 30 seconds in order to assure prevention of spreading of the water repellent forming solution from the rear surface of the fabric to the surface of the fabric. A water repellent agent is bound on the fabric by dry-heating the fabric at 180° C. for 30 seconds in the tenter.
When a drop of distilled water was placed on a surface of the above-processed perspiration-absorbing, quick-drying fabric using a spuit, it was observed to the eyes of an observer that the water drop was sucked into the water absorbing holes corresponding to non-water repellent finished parts and there was no moisture remaining on the water repellent layer. It was also observed that the water drop absorbed and transferred to the hydrophilic part through the water absorbing holes was spread fast across the whole hydrophilic part. It was also observed that moisture coming out onto the surface of the perspiration-absorbing, quick-drying fabric did not permeate to the rear surface again. Although the surface was fully wet, the partially water repellent finished rear surface was dry.
That is, no difference was found between Embodiment 4 and Embodiment 3. Therefore, a very effective perspiration-absorbing, quick-drying fabric may be fabricated using a general fiber in the water repellent finishing method of the present invention. Further, perspiration-absorbing, quick-drying clothes may be made conveniently using other types of fabrics in the water repellent finishing method of the present invention.
While the embodiments of the present invention have been described above, those skilled in the art will understand that many modifications and variations can be made to the present invention by adding, changing, or removing components without departing the scope and spirit of the present invention.
