Description

Stretch fabric

    The present invention relates to stretch fabrics having antimicrobial and deodorant properties.

    In recent years, the demand for comfort in the daily life has been increasing, attracting attention as well as the comfortable elasticity of the garment fabric (cloth fabric, knitted fabric, textile structure, etc.) as well as deodorant.

For example, modified cellulose fibers obtained by graft copolymerization of methacrylic acid to cellulose fibers such as cotton fibers are known as being excellent in odor removal to odors such as ammonia and manure odor. (See, for example, Japanese Patent Laid-Open No. 6-184941). On the other hand, as the aging society with respect to the odor removal properties, in particular, the odor removal function of the middle-aged body odor is required. In general, the middle-aged body odor is considered to be composed of each of the odor components such as ammonia, acetic acid, isogil acetic acid and nonenal, and in accordance with the evaluation criteria of "odor removal processing" published by the Textile Evaluation Technical Council According to the present invention, the function of removing all components of ammonia, acetic acid, isogyl acetic acid and non-nal is essential for removing the middle-aged body odor.

Several attempts have been made to obtain fabrics having various odor removing functions, and the fabrics obtained by knitting raw fibers having titanium oxide photocatalysts attached thereto (see Patent Document 2, for example), and the fabric product itself are treated with photocatalysts. The method of inject | pouring into a liquid and processing (for example, refer patent document 3) etc. is known.

However, it has been reported that no fabric has been reported to be able to obtain a fabric having excellent middle-age odor odor removal.

On the other hand, various attempts have been made to obtain a fabric having elasticity, and a stretch fabric provided with elasticity by mixing various elastic fibers is known (for example, see Patent Documents 4 to 7). However, since these stretch fabrics process the stretch fabric itself by a post-processing method, the fabrics provided with odor removing properties have a problem of insufficient washing durability and stretchability after washing.

In particular, lyocell is widely used as a medical material because of its soft texture and excellent hygroscopicity.

In the present invention, the cellulose-based fiber containing a carboxyl group is preferably a modified cellulose fiber obtained by graft copolymerization of methacrylic acid to the cellulose fiber. Since the modified cellulose fiber is excellent in adsorption to basic odorous substances such as ammonia, amine, and manure odor, it is preferable to use the odor removing fiber from the viewpoint of showing a synergistic effect on the odor removal property. In addition, a method for producing the modified cellulose fiber is disclosed in Japanese Patent No. 3239146 (Japanese Patent Laid-Open No. 6-184941) owned by Japan Hair Dyeing Co., Ltd. For example, radiation is immersed in an aqueous solution of cellulose based fiber products in an aqueous methanol solution containing a mixture of monomers produced from acrylic acid and sodium vinyl sulfonate or a mixture of monomers produced from acrylic acid and vinylbenzyl trimethyl ammonium chloride (VBTAC). It is a method of graft polymerization.

As the absorbent quick-drying polyester fiber, a large number of smaller holes are provided on the wall surface of the hollow fiber, and many gaps or holes are provided in the surface of the fiber, and the water absorbency is a minute hole of these fibers themselves, a gap in the surface of the fiber. For example, a fiber having a release cross-sectional shape such that moisture is absorbed into the voids between the fibers and the yarns can be used by synthetic fiber manufacturers as various absorbent quick-drying fibers. For example, the absorbent quick-drying polyester fibers include "Cool Max" made by Invista Co., Ltd. and "Seo" made by Toray Co., Ltd.

"," Werkiei "made by Teijin Fiber," Dry First "made by Toyo Spinning, and" Techno Fine "made by Asahi Kasei Fiber.

To impart absorption quick-drying, as described above, the aggregate itself such as polyester fiber or acrylic fiber is formed into a hollow fiber state using a material having less hygroscopicity, and has a shape of a fiber in which many smaller holes are provided in the wall surface thereof. Many gaps or holes are provided in the surface of the fiber, and the water absorbency is absorbed by moisture such as microporous holes of the fiber itself, fibers of a heterogeneous cross-sectional shape in which water is absorbed into the gaps between the fiber surfaces, the space between the fibers, and the yarns. Microporous holes and voids are mentioned.

If necessary, a polyester conductive fiber may be used as the antistatic soluble fiber. As a conductive material of the conductive fiber, for example, a composite polyester fiber using carbon black (for example, "Beltron" made by Kanebo Fiber Co., Ltd.), white copper iodide (Copper (I) iodide) or a metal complex oxide Composite polyester fibers using (for example, TiO ₂ · SnO ₂ · Sb ₂ O ₂ ), and the like, but are not limited thereto.

The polyester fibers used in the present invention preferably have a fiber surface area of 0.1 m 2 or more or a short fiber fineness of about 3 denier or less, more preferably a surface area of 0.12 m 2 or more or a short fiber fineness of about 3 denier or less per gram of woven fabric. . Since the action of attaching or absorbing the antimicrobial agent to the fiber depends on the surface area of the fiber or the short fiber fineness of the fiber, the antimicrobial activity has a high industrial washing durability in fibers having a surface area of 0.1 m 2 or more or short fiber fineness of about 3 denier or less. A fibrous structure (cloth) can be obtained.

For example, spun yarns made of 100% by weight of modified lyocell fibers modified by graft polymerization of 5% by weight of methacrylic acid by the above-described method for lyocell fibers, and metabolism by methism for lyocell fibers. 90% by weight of modified cotton modified by graft-polymerizing 10% by weight of methacrylic acid by conventional method for spun yarn made of 30% by weight of lyocell fiber and 70% of polyester fiber. And spun yarn consisting of 10% by weight of polyester fiber and the like. Most preferred is a spun yarn consisting of 75 to 60% by weight of modified lyocell fibers and 25 to 40% by weight of polyester fibers modified by graft weighting 10% by weight of methacrylic acid by releasing the lyocell fibers.

Furthermore, from the viewpoint of fabric feel and the like, by mixing cellulose fibers which have not been attempted to modify the above-mentioned materials, (A) adjusting the blending content of cellulose fibers containing carboxyl groups in the spun yarn to the above content rate It is preferably done. For example, a spun yarn made of 10% by weight of modified lyocell fiber and 90% by weight of lyocell fiber modified by graft polymerization of 5% by weight of methacrylic acid by the conventional method on lyocell fiber, and methacrylic by the method on lyocell fiber. 30% by weight of modified cotton modified by graft-polymerizing 10% by weight of methacrylic acid by the method for spinning yarn made from 30% by weight of modified lyocell fiber and 70% by weight of graft polymerized by graft polymerization of 10% by weight of acid. Spinning yarn composed of 70% by weight of cotton, spun yarn composed of 50% by weight of modified rayon and 50% by weight of rayon modified by graft polymerization of 10% by weight of methacrylic acid according to the conventional method for rayon, and cupra (copper ammonium rayon) 80% by weight of modified cupra (copper ammonium rayon) and 20% by weight of rayon were modified by graft polymerization of 12% by weight of methacrylic acid. And spun yarn composed of 10% by weight of modified lyocell fiber, 60% by weight, 30% by weight of polyester fiber, and the like. have.

(A) When the cellulose fiber containing a carboxyl group in the yarn is less than 5% by weight, the odor removal effect is significantly lowered. In addition, (A) the spun yarn consists of 100 to 5% by weight of cellulose-based fibers containing carboxyl groups and 0 to 95% by weight of polyester fibers, and also contains several synthetic fibers other than polyester fibers, for example, Polyamide fibers, polyacrylonitrile fibers, and natural fibers such as wool, silk, and the like may be combined in a proportion of less than 50% by weight.

In the present invention, (A) spun yarn is a blend yarn of a cellulose-containing cellulose-containing fiber (preferably modified lyocell fiber) and polyester fiber, in particular an absorbent quick-drying polyester fiber, from the viewpoint of improving the absorbency. It is preferable to, and it can be made into the blended yarn of the cellulose group fiber containing carboxyl group and antistatic polyester conductive fiber.

In addition, (A) the spun yarn can be prepared according to a known method, for example, that obtained by a manufacturing method selected from one or more selected from the group consisting of a ring traveler method, an open end method, a binding method and a square school method. desirable.

In the present invention, the fineness of (A) the spun yarn is not particularly limited, but 6 to 60 Young's number is preferable. Number means the unit of the thickness of the thread, the larger the number is the thinner the thread. In the present invention, both the singular and the bimodal in the above range of thickness can be suitably used.

In addition, the use of a yarn thicker than the number 6 is not preferable because the fabric is too thick and lacks softness, and the use of a thread thinner than the number 60 is not preferable because it becomes too thin and easily damaged.

In the present invention, the polyurethane elastic fiber may be any elastic fiber of polyurethane and polyurethane urea.

The urethane group concentration of the polyurethane constituting the polyurethane elastic fiber is preferably about 0.1 mol / kg or more and 3.5 mol / kg or less, more preferably about 0.4 mol / kg or more and 1.0 mol / kg or less. The urethane group concentration is calculated as (polymer diol (mol) contained in the polyurethane resin) x 2 / (polyurethane resin weight (kg)).

In addition, the effective terminal amine concentration of the polyurethane constituting the polyurethane elastic fiber is preferably 15 to 50 meq / kg. The effective terminal amine concentration is calculated by the following method. First, a solution of polyurethane or polyurethaneurea is diluted with N, N-dimethylacetamide (hereinafter abbreviated as "DMAc") to a concentration of 25 ml of a 2% by weight solution, and para-toluenesulfonic acid (0.01 The potentiometric titration is carried out with N) to obtain the sum of the contents of the primary and secondary amines (a). Next, salicylic aldehyde is added to this solution to determine the primary amine and secondary amine concentrations (b). The effective terminal amine concentration is calculated by the following equation.

Effective terminal amine concentration (meq / kg) = (a)-(b)

Polyurethane urea elastic fiber is preferably a polyalkylene ether diol having a number average molecular weight of about 250 to 10000 containing about 5 to 25 mol% of the structural unit a and about 95 to 75 mol% of the structural unit b Polyurethane urea obtained by polymerizing a diisocyanate compound and a symmetric diamino compound, more preferably a symmetric aromatic diamino compound, is an elastic fiber produced by spinning the polyurethane urea by a conventional spinning method.

[Structural unit a]

[Structural unit b]

In the structural units a and b, R 1 represents a straight chain alkylene group having preferably 1 to 3 carbon atoms, and R 2 represents hydrogen or preferably an alkyl group having 1 to 3 carbon atoms.

The structural unit a is for introducing a side chain into the polyalkylene ether diol, and is represented by, for example, a structural unit derived from 3-methyltetrahydrofuran or a structural unit derived from neopentyl glycol. Especially, the structural unit whose R <1> is a C2 straight-chain alkylene group and R <2> is hydrogen is especially preferable in said formula.

This polyalkylene ether diol has a side chain in a molecular chain, and thus has high flexibility and high recovery. Moreover, the polyurethaneurea elastic fiber manufactured using the polyetherdiol having such a side chain has enhanced durability against high temperature dyeing and high temperature heat set, so that a decrease in recovery stress is significantly suppressed.

In addition, the copolymer produced from the structural unit a and the structural unit b is preferably block copolymerization or random copolymerization, but it is particularly preferable that the structural unit a is abundantly present in the terminal portion of the molecular chain. That is, the ratio of the structural unit a (terminal a ratio) occupying the terminal of the molecular chain is larger than the ratio of the structural unit a (total a ratio) of the entire molecular chain, for example, the terminal a with respect to the total a ratio. It is preferable that a ratio value is 2 times or more. By doing so, it is possible to further increase the protection and maintenance of the recovery stress of the elastic fiber, especially during high temperature dyeing.

Thus, in order for the structural unit a to be abundantly present in the molecular chain terminal portion, the structural unit a is formed in the end of the step of polymerizing a unit forming the structural unit a and a unit forming the structural unit b. What is necessary is just to take the superposition | polymerization method of supplying and reacting the unit further to make it react. The proportion of structural units a present in the terminal can be controlled to a desired level depending on the amount of additional units to be supplied, the timing of supply, and the like.

In addition, in the case where 3-methyltetrahydrofuran and tetrahydrofuran are used as the two units described above, a strong acid obtained by ring-opening, for example, tetrahydrofuran, for example, sulfonic acid chloride or 2-fluorosulfo Polyalkylene ether diol consisting of the structural unit a and the structural unit b can be prepared by copolymerization at a temperature of about 0 to 50 ° C. in the presence of a nate, perchloric acid, or the like.

In the polyalkylene ether diol, the proportion of the structural unit a is 5 to 25 mol%, preferably 8 to 20 mol%. The structural unit b is the remaining ratio. By including the structural unit a in such a ratio, dyeing at a high temperature is more appropriately possible.

Polyurethane elastic fibers preferably used in the present invention is composed of a polyurethane urea polymerized by using the above-mentioned specific polyalkylene ether diol as a polyol, the elastic fibers of the elasticity is high, the strength is high, and moreover Dyeing is also possible, and even after dyeing, high elasticity can be preserved.

Examples of the symmetric diamino compound which is an example of the diamino compound used in the present invention include ethylenediamine, hexamethylenediamine, diaminodiphenylmethane, p-phenylenediamine, and the like. Phenylmethane (hereinafter abbreviated as "MBA") is preferred.

Moreover, as a diisocyanate compound, a normal thing is used, For example, diphenylmethane diisocyanate (it abbreviates as "MDI" hereafter) is used.

Polyurethaneureas can be prepared, for example, by chain stretching a prepolymer obtained from about 1 mole of polyalkylene etherdiol and about 2 moles of diisocyanate compound with a symmetric aromatic diamino compound. In the polyurethane urea, there is a structural unit containing a urethane bond (-NHCOO-) formed from a terdiol and a diisocyanate compound in a polyalkylene, and further, a urea bond formed from a symmetric aromatic diamino compound and a diisocyanate compound ( There is a structural unit with -NHCONH-). In addition, when MDI is used as a diisocyanate compound and MBA is used as a symmetric aromatic diamino compound, the reaction which adds water in DMDI solution of MDI and produces | generates MBA can also be used. That is, instead of adding MBA as a chain extender, water can be added to react the remaining MDI with water to generate MBA in the system, and the MBA can act as a chain extender to produce polyurethaneurea.

It is estimated that the structural unit (urea structural unit) which has a urea bond which exists in a polyurethane urea generally has a high heat resistance in many hydrogen bonds. However, in practice, fibers of polyurethane urea containing urea structural units formed from MDI and MBA are higher than those of polyurethane urea containing urea structural units formed from MDI and ethylenediamine. In addition, deterioration of the polymer during the dry heat treatment is suppressed to be small, the recovery stress preservation rate of the elastic fibers after the treatment is high, and the residual distortion reduction rate is increased. The reason for this is not accurate. However, when a large number of hydrogen bonds exist, water penetrates easily into the molecule, whereas a compound having an aromatic ring is difficult to penetrate into the molecule. Thus, as a chain extender, a symmetrical aromatic system having an aromatic ring like MBA In the case of using a diamino compound, it is believed that the penetration of water into the molecule is suppressed to a lesser degree, and that the hot water resistance of the resulting polyurethaneurea is improved.

Moreover, the polyurethane elastic fibers preferably used in the present invention are not only hot water resistant but also high dry heat resistance. The reason for this is not clear, but having an aromatic urea group in the polymer increases its cohesiveness, suppresses the movement of the glycol component when the elastic fiber is heated, and consequently, it is estimated that dry heat resistance is improved. Therefore, by using the polyurethane urea obtained by chain extension with the symmetrical aromatic diamino compound, such as diaminodiphenylmethane, it is thought that the heat-and-moisture resistance and the dry heat resistance of an elastic fiber can be improved.

Polyurethane urea elastic fiber used in the present invention is subjected to a condition that is exposed to hot hot water or high temperature steam in the high temperature dyeing process, or in addition to the stretching or tension is added, but the reduction of the recovery stress received by the elastic fiber under this condition It is assumed that it is not necessarily proportional to the number of hydrogen bonds. When the stretched elastic fiber is treated with hot water or steam, it is considered that thermal decomposition or hydrolysis of the polymer occurs and the recoverability of the elastic fiber is lowered. However, the elastic fibers preferably used in the present invention are lower than the elastic fibers before the treatment of the residual distortion of the elastic fibers treated under such wet heat treatment conditions.

It is preferable that the polyurethaneurea elastic fiber used for this invention also has the following characteristics. That is, the preservation rate (reservation rate compared with the recovery stress of the untreated yarn, hereinafter referred to as the hydrothermal preservation rate) of the yarn treated for 60 minutes with a suit in hot water at 130 ° C. is 55% or more and at the same time remaining by the treatment. It is preferable to have the characteristic that a distortion falls. Here, the hydrothermal retention rate is the recovery stress at 200% elongation that is preserved by heat treatment for 60 minutes while the elastic fibers are doubled. The recovery stress at 200% elongation is the recovery stress at the fifth recovery when the elastic fibers are repeatedly recovered five times, and the residual distortion is the value obtained by dividing the deformation after the repeated elongation by the original length. The hydrothermal preservation rate of the polyurethane urea elastic fiber is preferably 55% or more, particularly preferably 58% or more.

In addition, it is preferable that the residual distortion of the elastic fibers after such hydrothermal treatment is lower than that of the yarn before the treatment. Especially preferably, the residual distortion of the elastic fiber after the treatment is lowered by 1% or more than the residual distortion of the elastic fiber before the treatment. The smaller the residual distortion, the better the elastic recovery characteristics. Therefore, the lower the residual distortion means that the polymer constituting the yarn has excellent recovery characteristics even after the hydrothermal treatment. When the polyurethaneurea elastic fiber having such a hydrothermal preservation rate value or residual twisting property is applied to the yarn (A) of the present invention, it is subjected to high temperature and wet heat treatment during the dust-absorbing or supporting processing of the antimicrobial agent used in the present invention and during dyeing. The stretchable fiber structure thus obtained is a stretch fabric of the present invention having high recoverability and rich elasticity of the fabric.

In addition, the more preferable polyurethane urea elastic fiber, the retention rate of the recovery stress of the yarn treated with a suit for 1 minute in steam at 130 ° C (preservation rate compared to the recovery stress of the untreated yarn, hereinafter referred to as the steam retention) 85 % Or more, and at the same time, the residual distortion caused by the steam treatment is reduced. More preferred as a fiber having such a property is that the steam retention is 90% or more, and at the same time, the residual distortion of the yarn during the treatment is at least 1% lower than the untreated yarn. By fabricating a fabric as an elastic fiber structure using such an elastic fiber having a steam storage rate value or residual twisting property in the yarn (A), a stretch fabric having less trouble occurrence in hot dyeing or repeated dyeing can be produced.

More preferably, the polyurethane urea having a preservation rate (more specifically, a preservation rate in comparison with the recovery stress of an untreated yarn, hereinafter referred to as a dry heat preservation rate) of a yarn treated with a suit for 1 minute in air at 200 ° C. is 50% or more. Elastic fibers are used. It is more preferable that dry heat preservation rate is 55% or more. In the case of such an elastic fiber, even if it is mixed as an elasticity imparting material in the fabric using the yarn (A) which needs to be thermally set at a high temperature during dyeing processing, it can be thermally set without any problem, so that a good stretch fabric can be obtained.

Polyurethane urea elastic fibers preferably used in the present invention is preferably produced from the specific polyurethane urea described above, and has the characteristics as described above. Although the manufacturing method of the polyurethaneurea elastic fiber of such a characteristic is not specifically limited, It can manufacture by arbitrarily adjusting the composition, molecular weight, spinning conditions, etc. of a polyurethaneurea.

In addition, various inorganic and organic additives, stabilizers, etc. can be contained in the cellulose fiber, polyester fiber, and polyurethane elastic fiber containing a carboxyl group used by this invention. For example, various minerals represented by hydrotalcite compounds, huntite and hydromagnesite, tourmaline, and the like, oxides, complex oxides, hydroxides of metals represented by Ca, Mg, Zn, Al, Ba, Ti, and the like It may be included as long as it does not lose the effect.

In addition, when these inorganic additives are blended, organic substances such as fatty acids, fatty acid esters, and polyol organic substances, silane coupling agents, titanate couplings, etc. are used for the purpose of improving room dispersion and stabilizing radiation. It is also preferable to use an inorganic chemical surface-treated with a ring agent or a mixture thereof.

In addition, the cellulose-based fiber, polyester fiber, polyurethane elastic fiber containing a carboxyl group used in the present invention, if necessary, may contain various stabilizers, pigments and the like within the scope of not losing the effects of the present invention. . For example, the reaction of divinylbenzene and p-cresol as an additive polymer ("Methacrol" 2390 manufactured by DuPont), t-butyldiethanolamine and methylenebis (4-cyclohexyl isocyanate) Produced by Polyurethane ("Methacroll" manufactured by DuPont (trademark) 2462), a light-resistant agent, an antioxidant, etc., both hindered including various BHT and "smeizer" GA-80 manufactured by Sumitomo Chemical Co., Ltd. Phenolic drugs, benzotriazoles such as "Tinuvin" manufactured by Chiba-Geigi Co., benzophenones, Phosphorus-based drugs such as "Similizer" P-16 manufactured by Sumitomo Chemical Co., Ltd., various hindered amines, titanium oxide Inorganic pigments such as carbon black, fluorine resin powders or silicone resin powders, metal soaps such as magnesium stearate, or fungicides including silver, zinc or compounds thereof, odor removers, lubricants such as silicone and mineral oil, barium lactate,Various antistatic agents, such as cerium oxide, betaine, a phosphate system, etc. may be added, and may be made to react with a polymer and exist. In particular, in order to further enhance durability against light and various nitrogen oxides, a nitric oxide moisturizer such as HN-150 manufactured by Nihon Hydradine Co., Ltd., a thermal oxidation stabilizer such as "Smisorb" manufactured by Sumitomo Chemical Co., Ltd. You may contain light stabilizers, such as 300 # 622.

The antimicrobial agent to be used in the present invention is not particularly limited, and various organic and inorganic non-organic antimicrobial agents may be mentioned. Examples of the antimicrobial agent include inorganic nitrogen compounds containing organic nitrogen sulfur compounds, quaternary ammonium compounds, phosphate ester compounds, and metal ions. It is preferably generated from a compound selected from one or more from the group consisting of.

   Examples of the organic antimicrobial agent include organic antimicrobial agents having antimicrobial metal ions such as organic nitrogen sulfur compounds, phenolic compounds, organic tin compounds, organic copper compounds, and organic silver compounds, various organic silicon quaternary ammonium salts, and quaternary ammonium salts of alkyl phosphate esters. Organic antibacterial agents such as cetyldimethylammonium chloride, benzalkonium chloride, alkylarylsulfonate, halophenol and second mercury acetate, polyphenols, and chitosan.

In the antimicrobial agent, an amino group is preferred as the antimicrobial active site, aryl amino and diallyl amino are more preferred, and the amine antimicrobial agent specifically includes dimethyl amine and epicrohydrin condensates, diallyl amine derivative polymers, aryl amines and vinyls. Preferred are amine derivative polymers. Primary, secondary and tertiary aryl amine-based polymers in washing durability can further enhance the desired deodorizing effect and do not inhibit the softness of the fabric of the fabric obtained.

In addition, considering the antimicrobial activity is the state that the antimicrobial agent is attached to the surface of the fiber is the highest because of the high frequency of contact with bacteria. However, this condition is easy to peel off the antimicrobial agent and is not preferable from the viewpoint of washing durability. On the other hand, if the antimicrobial agent is uniformly diffused inside the fiber, the antimicrobial property is lowered, but washing durability is improved. As described above, it is considered that the antimicrobial agent is distributed in the link state from the inside of the fiber to the vicinity of the fiber surface or branched and diffused from the ground fiber surface to the inside in terms of antimicrobial activity and laundry durability. Antimicrobial processing by such an organic antimicrobial agent can be generally carried out by a batch treatment in which the antimicrobial agent is continuously padd, dried, or cured to a fabric material by heat treatment, or a heat treatment is performed using a liquid dyeing machine. It is also possible to use the fiber containing an antimicrobial agent previously as a constituent fiber, and it is preferable that it is provided as if an antimicrobial agent is exposed to the surface of a fabric material. Batch treatment is preferred in view of homogeneous odor removal and laundry durability.

Of these metal compounds, zinc hydroxide and basic zinc carbonate are particularly suitable.

In addition, an antimicrobial material prepared by impregnating a cloth in a dispersion obtained by dispersing the fine particle composition supported by silver on a zeolite in a binder, drying, and cutting into a predetermined dimension may be used. As the silver carrier, in addition to zeolite, hydroxyapatite, silica gel, silica alumina, nitconium phosphate, or the like can also be used.

Instead of silver supported on zeolites, antibacterial metals such as copper and zinc or their oxides, hydroxides, or salts, β-tjapricin (hinokithiol), polyphenones, teatrioyl, benzalkonium chloride, benzyl chloride Amphoteric surfactants, such as cationic surfactants, such as a zetonium system, alkylpolyaminoethylglycine hydrochloride, biguanide compounds, such as chlorhexidine chlorinate and polyhexamethylene biguanide hydrochloride, 2- (4-thiazolyl) benzoimidazole, N- (fluorodichloromethylthio) phthalimide, 2,3,5,6-chitochloro-4- (methylsulfonyl) -pyridine, 10,10'-oxybisphenoxyalcin, trimethoxysilyl- Propyloctadecyl ammonium chloride, 2-n-octyl- 4-isothiazolin-3-one, bis (2-pyridylthio- 1-oxide) zinc, dehydro sodium acetate, salicylic acid, paraoxy benzoic acid ester, N -Cocoyl-L-arginine ethyl ester pyrrolidone car Acid salt, it is preferred to employ a composition in which is supported on the carrier or impregnating the at least one of hexachloro-pen were attached using a binder.

Among them, zinc oxide not only expresses the odor removal ability as antibacterial activity but also increases the ability to chemically remove acid gases such as acetic acid and isogil acetic acid due to the decomposition of sweat in the body odor. In addition, zinc oxide is used as a raw material for cosmetics, and has been proved to have high safety for the body, which is excellent as an antibacterial agent and an odor remover of acid gas, which is often in direct contact with skin.

In addition, an antimicrobial agent that is sterilized and antibacterial by the photocatalytic action of the optical semiconductor powder is preferably used. Photocatalytic action is caused by the chemical action of an electrochemical cell in which one electrode is an optical semiconductor powder, which is an optical semiconductor powder, and the other electrode is a metal. As such an optical semiconductor powder, TiO 2, CdS, CdSe, WO 3, Fe 2 O 3, SrTiO 3, KNbO 3, and the like are used, and various metal powders such as gold, silver, platinum, and copper are used as the metal powder.

In the present invention, the antimicrobial agent is preferably about 0.1 to 10% by weight, more preferably about 0.1 to 5% by weight, or supported on the weight of the entire fabric.

In the stretch fabric of the present invention, it is preferable that the pH of the treatment liquid containing the antimicrobial agent is in the range of 5.0 or more and 6.0 or less when the antibacterial agent is absorbed or supported.

That is, the dust removal or support treatment of the antimicrobial agent to the stretch fabric containing (A) 99 to 70% by weight of the yarn and (B) 1 to 30% by weight of the polyurethane elastic fiber can be performed by a conventional method. For example, batch treatment or continuous treatment may be performed by adding an antimicrobial agent at the same time in the dyeing solution of the fabric. In the case of removing or supporting an independent antimicrobial agent alone, an antimicrobial agent may be used as a solvent (eg, water, Batch treatment method by impregnating the fiber product including the fabric or fabric in the treatment solution dissolved or dispersed in an organic solvent such as methanol) and heat treatment in a liquid dyeing machine, or continuous squeezing by uniformly squeezing dry in mangroves after dipping. And a treatment method. Among them, batch treatment is preferred from the viewpoint of obtaining a homogeneous odor removing ability. In this case, it is preferable that the treatment solution maintains acidity from the viewpoint of protecting the carboxyl groups present in the fabric and expressing good odor removing ability, and the pH of the preferred treatment solution including the antimicrobial agent is suitably in the range of 5.0 or more and 6.0 or less. In this case, a prescribed amount of the antimicrobial agent may be uniformly absorbed into the stretch fabric and be absorbed or supported. In the process performed by adding antibacterial agent at the same time in the dyeing solution of cloth, pH of dark color such as black or indigo is appropriate from 5.0 to 6.0 in terms of color development, and pH of white or cloudy color is odor removal ability and yellowing In view of this, 5.5 to 6.0 are appropriate. In addition, the extraction or dipping process time is usually about 1 ~ 120 minutes is appropriate.

In the present invention, the imparting odor removal property is a polyurethane-based resin having an odor removal ability with respect to nonenal and isogil acetic acid, a carboxyl group having an odor removal property with respect to an alkaline gas such as ammonia, and an acid such as acetic acid and isogil acetic acid. It is provided by the cellulose fiber which has an odor removal property with respect to gas, and is also performed using the antimicrobial agent which suppresses the growth of the bacteria which decomposes manure and sweat and produces a bad smell. In this case, as described above, it is possible to use an antimicrobial agent having both antibacterial and odor removing properties, which decomposes an organic substance by generating active oxygen by ultraviolet irradiation using a photocatalyst such as titanium oxide.

Furthermore, if necessary, for example, activated carbon, silica gel, alumina, activated clay, molecular sieves, amorphous aluminosilicates having a large specific gravity, and the like, substances having high adsorption performance against odor components such as ammonia, methyl mercaptan, hydrogen sulfide ( Deodorant) may be added or adhered to the fiber surface. Of course, it is possible to use fibers in which the deodorant has already been used.

In addition, as an odor remover, ceramic powders such as zeolite, apatite (apatite), activated carbon, activated alumina, activated silica gel, bentonite, or sepiolite, and silk fibers, metal salts such as iron and copper, and mixtures thereof Can be mentioned. Since these odor removers not only have a deodorizing action but also have a hygroscopic action, they can impart both functions of deodorization and moisture absorption to a fabric as one component. Especially, zeolite is mentioned as a preferable thing. Zeolites have a large specific surface area because they have anhydrous micron pores of amorphous or honeycomb shape. Therefore, when it encounters moisture, moisture is absorbed in the pores, and at the same time, moisture is absorbed as well as inorganic gases including four major odors (ammonia, trimethylamine, hydrogen sulfide, methylmercaptan) and organic gases including isogilic acid and phenol. .
