Description

  The present invention relates to a fiber structure and a manufacturing method thereof. More specifically, the present invention relates to a fiber structure capable of preventing yellowing of an elastic fiber due to an oxidizing air pollutant and preventing generation of discoloration and chlorine odor due to chlorine, and a method for producing the same.

Conventionally, it is known that a fiber structure such as a fiber fabric and a fiber product obtained by sewing the fiber fabric may cause yellowing while being stored in a warehouse or displayed in a store. Such a trouble occurs frequently when the fiber structure is dyed in a fluorescent color or a light color system. One of the causes of yellowing is that a yellowing substance is generated on the fiber surface when an oxidizing air pollutant such as NO _x (nitrogen oxide) gas is adsorbed on the fiber structure.

Among these, yellowing due to nitrogen oxides is particularly remarkable in elastic fibers such as polyurethane elastic fibers, and measures are taken at the raw yarn production stage. For example, Patent Documents 1 and 2 disclose polyurethane elastic fibers excellent in NO _X yellowing resistance obtained by spinning a polyurethane composition composed of polyurethane and hydrazine-based compounds. However, elastic fibers are mixed in an appropriate amount in order to give an appropriate stretch property to the fiber structure, and are not themselves the main constituent of the fiber structure. Therefore, even if the polyurethane elastic fiber has NO _X yellowing resistance, there is a problem that yellowing of the entire fiber structure cannot be prevented.

  In addition, it is known that swimsuits frequently used in pools may cause discoloration due to oxidative decomposition of dyes by chlorine for disinfection. Therefore, in order to improve the fastness of chlorine, for example, when the fiber structure is mainly made of a nylon material, the fiber structure is treated using various synthetic fixing agents or natural tannin-based fixing agents. . Among them, the method using a natural tannin-based fixing agent is regarded as the most effective means at present. However, since natural tannin itself is brown, there is a problem that the fiber structure is easily discolored and it is particularly difficult to obtain a clear color.

  Usually, polyurethane elastic fibers are used in a bathing suit. In order to prevent chlorine deterioration of polyurethane, a metal oxide-containing one is used. However, when it is treated with a natural tannin-based fixing agent, there is a problem that its ability to prevent deterioration is impaired.

Another harmful effect of chlorine is the generation of chlorine odor. When active chlorine remains in a fiber structure such as a swimsuit, an unpleasant chlorine odor is generated over a long period of time, and a method for preventing this is strongly desired. At present, various deodorizing and deodorizing processing methods have been proposed in the market, but most of them deal with bad odors that occur in daily life, such as body odor, rot odor, and tobacco odor. As a method for deodorizing, for example, Patent Document 3 discloses that an inorganic substance having an adsorptivity such as zeolite and a hydrazine derivative are fixed to the surface of a fabric made of cotton, polyester, or acrylic. In addition, titanium oxide and a hydrazine compound are imparted to the surface of the polyester fabric. Patent Document 5 discloses that an inorganic substance having an adsorptivity such as zeolite and a hydrazine derivative are mainly applied to a pile portion of a nylon carpet. Each grant is described. However, these methods use an adsorbent composed of an inorganic substance together with a hydrazine derivative, and this adsorbent adsorbs not only active chlorine but also NO _x gas, so that the fastness of the fiber structure is increased. There is a problem that it falls.

  Furthermore, even when the fiber structure contains polyester (sometimes referred to as regular polyester) or cationic dyeable polyester, an effective method for improving chlorine fastness has not been developed yet.

  The present invention has been made in view of such a current situation, and an object of the present invention is to prevent yellowing of a fiber structure due to an oxidizing air pollutant that may occur during storage in a warehouse or during display at a store. In addition, without being limited by the material, hue, and dye used, the fiber structure capable of maintaining sufficient chlorine fastness and imparting the ability to deodorize chlorine, and a method for producing the same Is to provide.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor applied a hydrazine-based compound as an antioxidant to a fiber structure containing elastic fibers together with a binder, and coated the fiber surface thereby. The present inventors have found that yellowing due to an oxidizing air pollutant in a fibrous structure containing the fiber structure, discoloration due to chlorine, and generation of chlorine odor can be effectively prevented, and the present invention has been completed based on this finding.

  That is, this invention relates to the fiber structure containing the elastic fiber which has the mixture film which consists of a hydrazine type compound and a binder on the fiber surface.

  The elastic fiber is preferably a polyurethane elastic fiber or a polyester elastic fiber.

  The hydrazine-based compound is preferably at least one compound selected from hydrazine salts, hydrazides, hydrazones and carbazides.

  The binder is preferably one or more compounds selected from acrylic resins, silicone resins, and fluorine resins.

  The fiber structure is preferably a woven fabric, a knitted fabric or a non-woven fabric.

  Moreover, it is related with the manufacturing method of the fiber structure containing the elastic fiber including the process of forming the mixture film which consists of a hydrazine type compound and a binder on the fiber surface.

  According to the fiber structure and the manufacturing method of the present invention, it is possible to prevent yellowing of the fiber due to the oxidizing air pollutant. Therefore, the fiber structure for all uses requiring prevention of yellowing during storage or display. Can be applied to. In addition, it is possible to prevent discoloration due to chlorine and generation of chlorine odor without being limited by the material, hue, and dye used, so that it can be used for applications that come in contact with high concentrations of chlorine, such as swimwear. Can also be preferably applied. In addition, since the performance can be maintained for a long time, it is extremely useful.

  The fiber structure of the present invention is made of fiber, and is a fabric such as raw cotton, tow, yarn, woven fabric, knitted fabric and non-woven fabric, or a final fiber product (sewn product such as clothes).

  The elastic fiber used in the present invention refers to a fiber having elasticity such as rubber, and is mixed in an appropriate amount for the purpose of imparting stretchability to the fiber structure.

  The elastic fiber is usually composed of a high melting point high crystalline part (hard segment) and a low melting point amorphous part (soft segment) in a block copolymer having high elasticity, and various elastic fibers can be obtained by this combination. . If the connection between the hard segment and the soft segment is a urethane bond, it is called a polyurethane elastic fiber (also called a urethane elastic fiber), and if it is an ester bond, it is called a polyester elastic fiber (also called an ester elastic fiber).

  In addition, fibers obtained by fiberizing a thermoplastic elastomer by melt spinning can also be used. A thermoplastic elastomer is a resin that exhibits intermediate physical properties between rubber and plastic, or properties close to rubber, and exhibits the same thermoplasticity as plastic. Examples of the type include polyesters, polyamides, polyurethanes, and polyolefins.

  Among these, polyurethane elastic fibers or polyester elastic fibers are preferably used in that appropriate stretchability and recoverability can be obtained for each application.

  The polyurethane elastic fiber is not particularly limited, such as polyether, polyester, and polycarbonate. Specifically, Lycra (registered trademark) manufactured by Toray DuPont Co., Ltd., Roika (registered trademark) manufactured by Asahi Kasei Co., Ltd., ESPAR (registered trademark) manufactured by Toyobo Co., Ltd., and Fuji Spinning Co., Ltd. Fujibo Spandex (registered trademark), Lubel (registered trademark) manufactured by Kanebo Synthetic Co., Ltd., Mobilon (registered trademark) manufactured by Nisshinbo Co., Ltd., and Spantel (registered trademark) manufactured by Kuraray Co., Ltd.

  As the polyester elastic fiber, a polyether ester type is representative, and specific examples include Lexe (registered trademark) manufactured by Teijin Limited and Success manufactured by Unitika Limited.

  It is also possible to use a combination of two or more of these elastic fibers.

  The fiber structure of the present invention may be mixed with other materials.

  The fiber material mixed with the elastic fiber is not particularly limited. For example, natural fibers such as cellulose (cotton, linen, etc.) and protein (wool, silk, etc.), regenerated fibers such as cellulose (rayon, cupra, etc.) and protein (casein fibers, etc.), cellulose (diacetate) , Triacetate, etc.) and semi-synthetic fibers such as protein (promix, etc.), polyamide (nylon 6, nylon 66, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, cationic dyeable polyethylene terephthalate) Etc.), polyolefins (polyethylene, polypropylene, etc.), polyacrylonitriles, polyvinyl alcohols, and polyvinyl chlorides, etc., and two or more of these are combined. Good.

  The mixing ratio of the elastic fibers varies depending on the required stretch properties and is not particularly limited, but is generally preferably 5 to 50% by weight. If the elastic fiber is less than 5% by weight, the stretch recovery property tends not to be sufficiently exhibited, and if it exceeds 50% by weight, the characteristics of the mixed fiber material tend not to be exhibited.

  After the elastic fibers are used alone or in combination with the other materials, a mixture film composed of a hydrazine compound and a binder is formed on the surface thereof.

  The fiber form when forming the mixture film may be any form such as raw cotton, tow, yarn, fabric (woven fabric, knitted fabric, non-woven fabric, etc.) or final fiber product (sewn product such as clothes). Among these, fabrics such as woven fabrics, knitted fabrics, and nonwoven fabrics are preferable in that a uniform mixture film can be formed on the fiber surface.

  The fiber structure of the present invention may be dyed with various dyes or may be undyed. Especially, it is preferable that it is what was dye | stained at the point which can exhibit the effect of this invention more notably. In addition, it is preferable that the elastic fiber is dyed to such an extent that when it is made into a fabric or a final fiber product, it is pulled with both hands and does not cause eye strain.

  As the dye, a known dye can be used without particular limitation depending on the fiber material mixed with the elastic fiber. Specific examples include direct dyes, reactive dyes, acid dyes, cationic dyes, chromium dyes, metal complex dyes, disperse dyes, and fluorescent dyes (fluorescent brighteners). It may be.

  Further, when a nylon material is mixed, it may be processed with various synthetic fixing agents or natural tannin-based fixing agents as long as the quality is not affected. By combining the mixture film composed of a hydrazine-based compound and a binder used in the present invention and the fixing agent, it is possible to drastically prevent discoloration due to chlorine.

The hydrazine-based compound used in the present invention acts as an antioxidant. That is, fiber structure of the present invention, during storage in a warehouse, or even oxidizing air pollutants such as NO _X gas during the exhibition in the shop is adsorbed by the antioxidant effect of the hydrazine compound, oxidizing air pollution Since the substance is inactivated, the formation of a yellowing substance can be prevented. Similarly, since the fiber structure of the present invention inactivates residual active chlorine, it can prevent discoloration due to chlorine and generation of chlorine odor.

Hydrazine compounds include hydrazine salts and hydrazides in that they have an antioxidant effect that sufficiently inactivates NO _x gas and active chlorine, and have a low degree of coloration when applied to fibers. , Hydrazones and carbazides are preferred, and two or more of these may be combined. More preferably, it is a compound having two or more hydrazide groups. Specifically, adipic acid dihydrazide, azelaic acid dihydrazide, succinic acid dihydrazide, glutaric acid dihydrazide, oxalic acid dihydrazide, suberic acid dihydrazide, sebacic acid dihydrazide, dodecanedioic acid dihydrazide, pimelic acid dihydrazide, malonic acid dihydrazide, malonic acid dihydrazide, Examples include terephthalic acid dihydrazide and polyacrylic acid hydrazide. Among them, sebacic acid dihydrazide, dodecanedioic acid dihydrazide, and isophthalic acid dihydrazide are preferable because of excellent washing durability.

  Since the hydrazine compound is hardly soluble in water, it is preferably used in a form emulsified and dispersed with a surfactant.

  In that case, it is preferable that the hydrazine compound is contained in the emulsified dispersion in an amount of 5 to 40% by weight, more preferably 10 to 30% by weight. If the amount of hydrazine compound is less than 5% by weight, it is necessary to use a large amount of the emulsified dispersion, which tends to cause chalk marks. If the amount exceeds 40% by weight, the stability of the emulsified dispersion tends to be impaired. It is in.

  Moreover, it is preferable to use 0.1-20 weight% of hydrazine type compounds with respect to the fiber structure which provides a liquid mixture, More preferably, it is 0.2-10 weight%. When the amount used for the fiber structure is less than 0.1% by weight, it tends to be difficult to sufficiently exert the effect of the hydrazine-based compound. Even if it is used in excess of 20% by weight, an effect exceeding it tends not to be obtained, which is not practical. Furthermore, the problem that the texture of a fiber structure hardens also arises.

  Hereinafter, when expressing the usage-amount of the agent with respect to the fiber structure which provides a mixture liquid, it describes with% owf.

  In order to fix the hydrazine compound to the fiber structure, a binder is used in the present invention. The binder is not particularly limited. Among these, acrylic resins, silicone resins, fluorine resins, and the like are preferable because they are widely available in the market and are excellent in handleability, and two or more of these may be combined. Of these, acrylic resins are preferred because of excellent washing durability. By using a binder in combination, the effect of the hydrazine compound can be maintained over a long period of time.

  It is preferable that the usage-amount of a binder is 1-500 weight part with respect to 100 weight part of hydrazine compounds, More preferably, it is 10-200 weight part. When the amount used is less than 1 part by weight, a sufficient amount of hydrazine-based compound cannot be fixed and washing durability cannot be obtained. When the amount used exceeds 500 parts by weight, the texture of the fiber structure is cured.

  In the method for producing a fiber structure of the present invention, the mixture liquid containing the hydrazine compound and the binder is applied to the fiber structure containing the elastic fiber, and then dried and heat-treated. A mixture film made of a binder is formed.

  Water is used as a solvent for the mixture liquid. If necessary, an emulsifying dispersant, a pH adjusting agent, a penetrating agent, a texture adjusting agent, or the like can be added to the mixture liquid.

  As a method for applying the mixture liquid to the fiber structure, a conventionally known method can be adopted, and examples thereof include a padding (mangle-pad) method, a spray method, a coating method, and a gravure method. What is necessary is just to select suitably considering the form etc. of a fiber structure.

  For example, when the form of the fiber structure is a fabric such as a woven fabric, a knitted fabric, or a non-woven fabric, a padding method is preferably used. According to the padding method, the mixture liquid can be applied to each fiber while maintaining the gap between the fibers, so that a uniform film can be formed. The amount of the hydrazine compound and binder used for the fiber structure is as described above, and these are given to the fiber structure in an appropriate amount by adjusting the concentration of the treatment liquid and the amount of the treatment liquid applied to the fiber structure. Is done.

  When using the padding method, the pickup rate is preferably 20 to 80%, more preferably 30 to 60%. If the pick-up rate is less than 20%, the concentration of the treatment liquid must be increased, and it tends to be difficult to apply uniformly, and if it exceeds 80%, the moisture content is high and uneven drying tends to occur. There is a tendency.

  The formed mixture film has a dry film thickness of preferably 5 to 100 μm, more preferably 10 to 30 μm. If the coating is thinner than 5 μm, the antioxidant effect tends to be reduced, and if it exceeds 100 μm, chalk marks tend to be generated.

  Next, the fiber structure provided with the mixture liquid is dried. The drying is not particularly limited as long as the moisture does not remain. In general, the reaction is performed at 110 to 140 ° C. for 1 to 5 minutes.

  Furthermore, when using self-crosslinking binders, it is necessary to heat-treat them under conditions sufficient for their crosslinking after drying. Generally, it is carried out under conditions of 150 to 190 ° C. and 1 to 5 minutes, although it varies depending on the type of binder. It is also possible to perform drying and heat treatment in one step.

  Thus, a mixture film comprising a hydrazine compound and a binder can be formed on the fiber surface.
