By the evaporation of the liquid in the deodorant liquid and the contraction after expansion of the thermally expandable microcapsule, an infinite number of spaces are generated near the deodorant composition, thereby increasing the probability of contact with the odor and the deodorant composition, and eliminating the deodorant. A reduction in odor performance is suppressed. Thus, it is possible to manufacture a deodorant fabric in which a decrease in deodorizing performance is suppressed.

  The deodorant liquid according to the present invention contains an amine compound, an inorganic porous material, a metal oxide, and a metal hydroxide, a thermally expandable microcapsule, and a binder resin. It is characterized by By adopting this configuration, the deodorant composition can be firmly attached to the fabric when it is applied to a fabric, so it exhibits deodorizing performance with excellent durability, and also deodorant performance by the binder resin.

  The concentration of the thermally expandable microcapsule is preferably 1 to 8% by mass. In this case, even when applied to a fabric, the reduction in deodorizing performance is sufficiently suppressed, and excellent deodorizing performance can be exhibited. More preferably, it is 1.5-6.5 mass%.

In this case, it is possible to suppress the falling off from the fabric, and it is possible to maintain the deodorizing performance over a long period of time, being excellent in the washing resistance and the abrasion resistance.

  In the deodorant fabric according to the present invention, the deodorant composition and the thermally expandable microcapsule contained in the deodorant liquid adhere to at least a part of the fabric by the binder resin. Thus, it is possible to provide a deodorant fabric which exhibits a sufficient deodorizing effect while suppressing the deterioration of the deodorizing performance.

  The fiber product according to the present invention is characterized in that at least a part of the deodorant cloth is provided. This fiber product can exhibit excellent deodorizing performance.

  In the present invention, examples of the amine compound constituting the deodorizing composition include a hydrazine derivative or an inorganic silicon compound carrying a polyamine compound. Examples of the hydrazine derivative include those obtained by reacting a hydrazine compound and a long chain aliphatic compound, and those obtained by reacting a hydrazine compound and an aromatic compound. Among them, one or two or more compounds selected from the group consisting of hydrazine and semicarbazide, and a group consisting of a monocarboxylic acid having 8 to 16 carbon atoms, a dicarboxylic acid, an aromatic monocarboxylic acid, and an aromatic dicarboxylic acid. Selected from the group consisting of one or two compounds selected from the group consisting of hydrazine and semicarbazide and a monoglycidyl derivative having 8 to 16 carbon atoms and a diglycidyl derivative selected from the group consisting of hydrazine and semicarbazide The reaction products with one or more of the compounds mentioned are suitable.

  By using such a hydrazine derivative, it is possible to cause a chemical reaction with respect to aldehydes to exhibit an excellent adsorption action and to ensure malodor removal performance. Specific examples of the reaction product include sebacic acid dihydrazide, dodecanoic acid dihydrazide, isophthalic acid dihydrazide and the like. The solubility of such a hydrazine derivative in water is preferably 5 g / L or less at 25.degree. If the solubility in water is within this range, the hydrazine derivative is prevented from being dissolved in the water and flowing out, even when it comes in contact with the water by washing or the like.

  The inorganic silicon compound carrying a polyamine compound is not particularly limited, and examples thereof include porous silicon dioxide carrying a polyamine compound, aluminum silicate carrying a polyamine compound, and the like.

  The polyamine compound is not particularly limited, and examples thereof include aliphatic polyamines, aromatic polyamines, alicyclic polyamines and the like. Specifically, for example, diethylenetriamine, tetraethylenepentamine and the like can be mentioned.

  The polyamine compound is particularly effective for deodorizing an aldehyde gas, and the inorganic silicon compound is effective for deodorizing a basic gas, and an inorganic porous material, a metal oxide, and a metal hydroxide are used in combination. By this, various odors can be effectively deodorized.

  Next, the inorganic porous material constituting the deodorizing composition of the present invention has a large surface area because of its porosity, and is excellent in the ability to adsorb malodor. For example, as such an inorganic porous material, porous silica, activated carbon, zeolite, silica gel, barley stone, etc. may be mentioned. Among them, it is preferable to use a zeolite having an excellent adsorption ability to acetic acid, ammonia gas and the like. In addition, zeolite is good because it is white and has less influence on the color of the fabric than activated carbon when supported on fibers. Zeolite has a framework structure in which silicon and aluminum are three-dimensionally linked via oxygen. This skeleton is very useful as an adsorbent because holes (pores) at the molecular level open and various molecules such as water and organic molecules are incorporated into the skeleton.

  There are various types of zeolite, and among them, MFI-type artificial zeolite is very effective as an adsorbent because two kinds of pores derived from crystal structure are connected three-dimensionally. It is recognized as a thing. In the present invention, when MFI-type zeolite is used as an adsorbent, it exhibits excellent adsorption ability to basic gases such as ammonia and trimethylamine, and also adsorbs trace amounts of neutral gases such as aldehydes and 1-nonene. Demonstrate excellent effects.

  In the present invention, examples of the metal oxide constituting the deodorizing composition include metal oxides such as copper oxide, alumina, titanium oxide, zinc oxide, iron oxide, zirconium oxide and the like. It is not limited.

  In the present invention, examples of metal hydroxides constituting the deodorizing composition include metal hydroxides such as zirconium hydroxide, magnesium hydroxide, aluminum hydroxide, ferrous hydroxide, copper hydroxide and the like. It is not particularly limited to the illustrated ones.

  In the present invention, as thermally expandable microcapsules to be mixed with the deodorant liquid, capsules in which liquid hydrocarbon is contained in a shell of a thermoplastic resin can be mentioned. The average particle size of the thermally expandable microcapsules is 5 μm to 50 μm, and particularly preferably 8 μm to 18 μm. The hydrocarbon changes to a gas at a temperature below the softening point of the thermoplastic resin that constitutes the shell, and the thermally expandable microcapsules begin to expand from the expansion start temperature by raising the temperature to form a balloon. However, after reaching the maximum expansion temperature, the expansion ratio becomes maximum.

  In the present invention, the maximum expansion temperature of the thermally expandable microcapsule is preferably in the range of 105 ° C to 165 ° C, and more preferably 105 ° C to 145 ° C. Within this range, the thermally expandable microcapsule can be relatively easily brought to the maximum expansion ratio by heating with a known dryer or heat treatment apparatus. The expansion ratio of the thermally expandable microcapsule is 2 to 12 times, and more preferably 2.5 to 5.5 times.

  The softening temperature of the thermoplastic resin as a shell of the thermally expandable microcapsule is 100 ° C. to 150 ° C. As a thermoplastic resin having a softening point in this temperature range, for example, acrylonitrile, vinyl acetate, vinyl chloride, vinylidene chloride , Styrene, methyl methacrylate and the like.

  Examples of the liquid hydrocarbon in the shell of the thermally expandable microcapsule include normal butane, propane, propylene, butene, isobutane, isopentane, neopentane, normal pentane, hexane, heptane, petroleum ether and the like.

  In the present invention, any resin may be used as the binder resin to be blended in the deodorizing solution. For example, self-crosslinking acrylic resin, methacrylic resin, urethane resin, silicone resin, glyoxal resin, vinyl acetate resin, vinyl acetate resin, vinylidene chloride resin, butadiene resin, melamine resin, epoxy resin, acrylic-silicon copolymer resin, ethylene- Examples include vinyl acetate copolymer resin, isobutylene maleic anhydride copolymer resin, ethylene-styrene-acrylate-methacrylate copolymer resin, and the like. In addition, two or more of these resins may be mixed to form a binder resin. The solid content concentration in the deodorant liquid of the binder resin is preferably 20 to 35% by mass, and by setting the solid content concentration in this range, the deodorant composition and the thermally expandable microcapsule are firmly attached to the fabric via the binder resin. be able to. In this way, it is possible to suppress the falling off from the fabric, and it is possible to maintain the deodorizing performance over a long period of time, being excellent also in the washing resistance and the abrasion resistance.

  In the present invention, the compounding ratio of the amine compound contained in the deodorant composition, the inorganic porous material, the metal oxide, and the metal hydroxide is not particularly limited, but the compounding amount of the metal oxide such as titanium oxide increases Also, the probability of bonding of the metal oxide to the fiber fabric increases, which causes the fiber fabric to deteriorate. Moreover, when the compounding quantity of inorganic porous materials, such as a zeolite, increases, a cloth will whiten unpreferably.

  Moreover, in the prior art, when the compounding quantity of binder resin increased, the binder resin will cover the surface of a porous substance or a metal oxide, and the fall of deodorizing performance was seen. In the present invention, in the deodorant composition containing the deodorant composition and the thermally expandable microcapsule and the binder resin, even if it is applied to a fabric, the deterioration of the deodorant performance is suppressed and the deodorant performance can be exhibited.

  As a particle size of the said deodorizing composition, the deodorizing composition whose average particle diameter is 10 nm-100 micrometers is preferable. Since the average particle diameter is 10 nm to 100 μm, deodorant fabrics having a favorable feeling can be obtained without receiving a rough feeling when supported on a fabric.

The application amount of the deodorant is preferably 10 to 1000 g / m ² . By setting the content in this range, it is possible to manufacture a deodorant fabric in which the deterioration of the deodorizing performance is sufficiently suppressed and the deodorizing performance is remarkably excellent. If it is less than 10 g / m ² , sufficient performance can not be obtained, which is not preferable. Moreover, there is no big improvement even if it exceeds 1000 g / m < ² >, and cost will be increased needlessly.

  In the method of preparing a deodorant liquid according to the present invention, first, a deodorant composition containing an amine compound, an inorganic porous material, a metal oxide, and metal hydroxide, a thermally expandable microcapsule, and a binder resin And deodorizing liquid in which water is uniformly dispersed. At this time, it is preferable to disperse the deodorizing composition, the thermally expandable microcapsules, and the binder resin as well as possible, and for the binder resin, it is more preferable to form an emulsion state with water. In addition, it is preferable to disperse the binder resin after dispersing the deodorant composition in water before blending, since the deodorant composition and the binder resin can be dispersed more uniformly.

  In the deodorant liquid, various additives such as a surfactant, a dispersing agent, and a thickener may be appropriately blended to improve various characteristics. When flame retardancy and flameproofness are required, processing with a flame retardant and a flameproof agent is appropriately performed.

  Examples of the surfactant include, for example, a hydroxyethylidene phosphonate, an alkyl sulfosuccinate, an alkyl sulfonate, a monoalkyl phosphate and the like as an anionic surfactant. The anionic surfactant adsorbs to the dispersed particles to give a negative charge, and stabilizes the liquid by the repulsion between the negative charges. The blending amount of the anionic surfactant is preferably 0.1 parts by mass to 5 parts by mass with respect to 100 parts by mass. If the amount is less than 0.1 parts by mass, the stability of the dispersion is not effective, which is not preferable. In addition, even if it exceeds 5 parts by mass, there is no significant improvement in the stability of the dispersion to the input amount, and the viscosity of the deodorant composition is undesirably increased.

  The dispersant is not particularly limited, but in order to improve the liquid stability of the deodorant, it is preferable to contain 0.1 to 5 parts by weight of an anionic dispersant with respect to 100 parts by weight of the deodorant composition. In the case of dispersing agents other than anionic dispersing agents, aggregation may occur depending on the conditions (pH value, temperature, etc.), which is not preferable, but the generation can be suppressed by adjusting the pH. In addition, when the amount of the anionic dispersant is less than 0.1 parts by weight, the effect is small, and even if it is added in excess of 5 parts by weight, the effect corresponding to the amount of addition can not be obtained.

  Examples of the thickening agent include daibutan gum, guar gum, xanthan gum, wera gum, zeta sea gum, polyethylene oxide, polyvinyl pyrrolidone, polyvinyl alcohol and sodium polyacrylate.

  The flame retardant is not particularly limited, and phosphorus-based flame retardants (melamine polyphosphate, phosphate esters, ammonium polyphosphate etc.), inorganic flame retardants (thermally expandable graphite, zinc borate, barium metaborate, oxidized) Aluminum, zinc oxide, iron oxide, aluminum hydroxide, magnesium hydroxide and the like), nitrogen-based flame retardants (melamine cyanurate, melamine oligomer condensation and the like) can be used.

  The means for applying the deodorizing solution in the present invention is not particularly limited, and examples thereof include a spray method, an immersion method, a coating method, and a padding method. For application, for example, in the case of a carpet, the pile yarn, the base fabric, and the backing layer may be applied alone, or the deodorant solution may be applied in the form of a skin layer in which the pile yarn is implanted. It may be applied in a form in which the skin layer and the backing layer are adhesively integrated via the adhesive layer. Alternatively, the deodorant may be mixed with the treatment solution of the filler layer and applied by spraying or roll coating to form a filler layer having a deodorizing function. Moreover, in the case of a curtain, after sewing, you may apply by the spray method etc., and it may apply and dry by the immersion method, the coating method, the padding method etc. in the state of cloth | dough.

  As described above, the deodorant is applied and then dried, but as the drying means, a method of heat treatment is preferable from the viewpoint of drying efficiency.

  In the method for producing a deodorant fabric of the present invention, the coated fabric is heat-treated at a temperature within the range of ± 30 ° C. of the maximum expansion temperature of the heat-expandable microcapsules. By heat treatment within this range, the thermally expandable microcapsules expand to the maximum expansion ratio while the liquid in the deodorant liquid applied to the fabric evaporates, and the deodorant composition in the deodorant liquid is It adheres to the fabric through the binder resin together with the expandable microcapsules. For example, if the maximum expansion temperature of the thermally expandable microcapsule is 130 ° C., the heat treatment may be performed in the range of 100 ° C. to 160 ° C. As the heat treatment proceeds, evaporation of the liquid in the deodorant liquid and expansion of the thermally expandable microcapsule create an infinite number of spaces near the deodorant composition, thereby increasing the probability of contact between the odor and the deodorant composition. The deterioration of the deodorizing performance is suppressed. In this way, the fall of deodorizing performance is controlled and a deodorant cloth can be manufactured.

  Moreover, in the other manufacturing method of the deodorizing fabric of this invention, the fabric after application is heat-treated at temperature 30 degreeC or more higher than the maximum expansion temperature of the said thermally expandable microcapsule. By heat treatment within this range, the thermally expandable microcapsules expand to the maximum expansion ratio while the liquid in the deodorant liquid applied to the fabric evaporates, and then shrinkage occurs, and the deodorant composition in the deodorant liquid The matter adheres to the fabric via the binder resin together with the shrunk thermally expandable microcapsules. For example, when the maximum expansion temperature of the thermally expandable microcapsule is 130 ° C., the heat treatment may be performed at a temperature of 160 ° C. or more. As heat treatment proceeds, evaporation of the liquid in the deodorant liquid and shrinkage after expansion of the thermally expandable microcapsule create an infinite number of spaces in the vicinity of the deodorant composition, thereby contacting the odor with the deodorant composition. The probability is increased, and the deterioration of the deodorizing performance is suppressed. Thus, it is possible to manufacture a deodorant fabric in which a decrease in deodorizing performance is suppressed.

  In general, in addition to deodorizing performance, in many cases, processing is often performed to impart various functions such as flame retardancy, insect repellent, antifouling, etc. The pH value may swing to the acidic side or may shift to the basicity, which may lead to a decrease in the deodorizing effect. If the pH value of the deodorant fabric surface fluctuates to the acid side, the malodor removal rate of the acid gas is reduced, and if the pH value of the deodorant fabric surface fluctuates to the basicity, the malodor removal of the basic gas It will lower the rate. In the present invention, it is important to keep the pH value of the surface of the fabric before deodorizing treatment at 6 to 8, and the pH value of the surface of the fabric may be shifted to the acidic side by processing giving various functionalities. When it fluctuates, it is better to carry out neutralization treatment, and by adjusting the pH value of the fabric surface to 6 to 8 and then applying a deodorant, it works effectively on acid gas and basic gas. The deodorizing cloth can be made to have a good deodorizing efficiency.

  It does not specifically limit as a fabric of this embodiment, For example, a woven fabric, a knitted fabric, a nonwoven fabric can be mentioned. The fibers forming the fabric are not particularly limited, and fibers made of fibers such as polyester fibers, polyamide fibers, polypropylene fibers, acrylic fibers, rayon fibers and the like can be suitably used, and others such as hemp, cotton, wool and the like And the like can also be used. Moreover, as textile products, for example, skin wear fabrics, clothes, wallpaper, shoe insoles, upholstery, vehicle interior materials, car interior materials, vehicle ceiling materials, curtains or carpets can be mentioned. The places where such textile products are used are from those to be worn, to interiors of houses and cars, trains, passenger planes, and the like. Thus, the odor in the air can be deodorized around the textile.

  Next, specific examples of the present invention will be described, but the present invention is not particularly limited to these examples. In addition, although the material used is shown next, the list of the deodorizing liquid of the Example was shown in Table 1. Further, the deodorizing composition, the thermally expandable microcapsules, the adhesion amount of the binder resin to the fabric, and the heat treatment conditions were as shown in Table 2. Table 3 shows the results of deodorizing tests of various gases, that is, the reduction rate of odor and the evaluation results.

  The deodorant solutions of Examples 1 to 8 can efficiently adsorb and remove typical odors of basic gases, sulfur-based gases, acid gases and neutral gases, and they can be treated on fabrics as well. It was a deodorant in which the decrease in odor performance was suppressed. That is, the deodorant fabric to which the deodorant composition contained in these deodorant liquids adhered, the fall of the deodorizing performance intrinsic | native to a deodorant composition was suppressed, and the outstanding deodorizing performance was exhibited.

  On the other hand, in the deodorizing liquids of Comparative Examples 1 and 2, the odors of typical basic gases, sulfur-based gases, acid gases and neutral gases can not be uniformly eliminated, and thermally expandable micro In Comparative Example 3 in which the capsule is not contained, the deodorizing performance was significantly inferior to the original performance of the deodorant composition, and no satisfactory performance was exhibited.

<Deodorant test>
In addition, the measurement of the various deodorizing performance in the said example was performed as follows.
(Ammonia deodorizing performance)
A test piece (10 cm × 10 cm) is placed in a bag having an internal volume of 500 ml, ammonia gas is injected so that the concentration is 200 ppm in the bag, and the remaining concentration of ammonia gas is measured after 1 hour. From the measured values, the total amount from which the ammonia gas was removed was calculated, and from this the reduction rate (%) of the ammonia gas was calculated.

(Hydrogen sulfide deodorizing performance)
The reduction rate (%) of hydrogen sulfide gas was calculated in the same manner as the above ammonia deodorizing performance measurement except that hydrogen sulfide gas was used instead of ammonia gas and injection was performed so that the concentration was 20 ppm in the bag.

(Acetaldehyde deodorizing performance)
The reduction rate (%) of acetaldehyde gas was calculated in the same manner as in the above ammonia deodorizing performance measurement, except that acetaldehyde gas was used instead of ammonia gas to inject a concentration of 80 ppm in the bag.

(Acetate deodorizing performance)
The reduction rate (%) of acetic acid gas was calculated in the same manner as in the above ammonia deodorizing performance measurement, except that acetic acid gas was used instead of ammonia gas and injection was performed so that the concentration was 100 ppm in the bag.

(Formaldehyde deodorizing performance)
The reduction rate (%) of formaldehyde gas was calculated in the same manner as in the above ammonia deodorizing performance measurement, except that formaldehyde gas was used instead of ammonia gas and the concentration was 80 ppm in the bag.

(Trimethylamine deodorizing performance)
The reduction rate (%) of formaldehyde gas was calculated in the same manner as the above ammonia deodorizing performance measurement, except that the concentration was 60 ppm in the bag using trimethylamine gas instead of ammonia gas.

(Methyl mercaptan deodorizing performance)
The reduction rate (%) of formaldehyde gas was calculated in the same manner as the above ammonia deodorizing performance measurement, except that methyl mercaptan gas was used instead of ammonia gas and injection was performed so that the concentration was 40 ppm in the bag.

  Note that those with a removal rate of 95% or more are “◎”, those with a removal rate of 90% or more and less than 95% are “○”, and those with a removal rate of 80% or more and less than 90% are “Δ”, Those having a removal rate of less than 80% were evaluated as "x". Passed "○" or higher.
