Description

Method of deodorant finishing for acetate fiber

The present invention relates to a method for deodorizing acetate fibers, and more particularly, to deodorizing characteristics, while maintaining the fastness of dyeing, physical properties and water repellency to acetate fibers commonly used as lining paper for high-quality clothing or as a substitute for silk fiber. It is about how to give.

Acetate fibers are artificial fibers obtained from pulp, which is a natural material, using acetic anhydride and glacial acetic acid as subsidiary materials to transform cellulose into cellulose acetate esters, and then acetone as a solvent. Acetate fibers are highly hygroscopic, light and soft to the touch, and are highly regarded as excellent textile materials due to their elegant luster like silk and color development when dyed, and are used for high-end clothing such as ties, gowns, pajamas, shirts, suits and dresses. It is often used as lining material.

As garments, which were made mainly for the function of protecting the body, have improved the living standard of human beings, various functionalities such as aesthetics and comfort are required, and various high value-added functional products are being developed to satisfy them. In this regard, there is a growing interest in deodorizing fibers that can remove various odors that are unpleasant to people around them, such as body odor or tobacco smell.

Until now, the deodorant processing technology of textiles has been researched mainly in Japan. In the early stages of the deodorization, ammonia, hydrogen sulfide, trimethylamine, methyl mercaptan, etc., which are representative odors, have been attracting attention for deodorization of human body such as cigarette smell and sweat odor. The method of imparting odor to the fiber is a method of attaching a fragrance component to the fiber, a method of attaching a compound capable of chemically decomposing odor component gas to the fiber, and an inorganic substance capable of physically adsorbing odor component gas to the fiber. There is a method of attaching. Deodorants capable of removing odor components chemically or physically have been developed, but have been difficult to apply them effectively to textile products to have durability.

As a specific example of the deodorizing technology, there is a method using a photocatalyst titanium oxide. However, photocatalyst titanium oxide has a problem that it is impossible to use it directly in textile products because the oxidation power is too strong to decompose organic fibers or dyes together. In addition, a method in which a deodorant carrying polyethyleneimine and a nonionic hygroscopic organic substance is applied to acrylic fibers (Japanese Patent Laid-Open Publication No. H3-146064), and after imparting metal porphyrin containing an amino group to the swollen gel fiber in the acrylic fiber manufacturing step, the fiber Manufacturing method of acrylic fiber dried and densified (Japanese Patent Laid-Open Publication No. 62-141128), air cleaning filter combining a plurality of carriers impregnated with a deodorant active ingredient against a plurality of malodors (Japanese Patent Laid-Open Publication No. Hei 2-22673) Although there are proposals such as these, they have a disadvantage in that it is difficult to use them as a garment material because they are not satisfactory washing durability or dyeing durability.

In the deodorant processing technology for textile products used in clothing, a method of attaching a deodorant capable of removing odor components to fibers using a binder such as a urethane resin or an acrylic resin is mainly used. In this regard, the development of deodorizing fibers by treating chitosan or modified chitosan, carboxylic acid polymers, zinc oxide and binder resins to fibers, and attaching them to fibers using inorganic compounds and anionic polymer binders have been developed in Japan. In Korea, a method of coating a microcapsules made of joiner extract on fibers with a binder (Korean Patent 1996-0023398) has been proposed.

However, most of these deodorizing techniques have been developed for application to natural fibers and some synthetic fibers such as cotton, and the deodorizing method of acetate fibers has not been developed yet. Deodorization processing of textile products should satisfy the durability against washing and other treatments, no change in color fastness, and little change in physical properties such as tensile strength. In view of this aspect, when applied to apparel acetate fibers, there is no change in color, color fastness and physical properties and satisfactory washing durability has not been developed yet.

Therefore, the technical problem to be achieved by the present invention is to provide a deodorant processing method of acetate fibers excellent in washing durability without color change, color fastness and mechanical properties to solve such problems.

Figure 1 shows a scanning electron microscope (SEM) photograph immediately after the deodorizing process of the acetate fiber deodorized according to Example 1 of the present invention.

2 shows scanning electron microscope (SEM) photographs after 20 times of dry cleaning after deodorization of acetate fibers deodorized according to Example 1 of the present invention.

The present invention to achieve the above technical problem,

(a) preparing a deodorizing agent in which a binder resin selected from the group consisting of zinc oxide, silver, silica and urethane resin, acrylic resin, polysiloxane resin, fluorine resin and melamine resin is dispersed in water;

(b) impregnating and drying the dyed acetate fibers in the deodorant; And

(c) heat treating the dried acetate fiber to provide a method for deodorizing acetate fiber, comprising fixing the active ingredient of the deodorant agent to an amorphous region of the acetate fiber.

In the method for deodorizing the acetate fiber of the present invention, a component that exhibits deodorizing characteristics is durable through acetate fiber by impregnating and drying a mixture containing zinc oxide, silver, silica and a urethane resin, and then heat-treating the acetate fiber. It is attached. That is, according to the deodorizing processing method of the acetate fiber of the present invention, due to the synergistic deodorizing properties of zinc oxide, silver and silica, it is possible to impart high deodorizing performance to 100% acetate fiber, and the resin firmly By combining, the deodorant laundry durability is excellent. In addition, the color and mechanical properties of the dyeing before and after the deodorizing process does not change, washing or friction and sweat fastness are also maintained. Hereinafter, unless otherwise indicated in the description of the present invention,% means weight%.

Hereinafter, each step of the deodorizing processing method of the acetate fiber according to the present invention will be described in detail.

(1) Preparation process of deodorant processing agent

Deodorant processing agent used in the deodorant processing method according to the present invention is zinc oxide; silver; Silica; And a binder resin selected from the group consisting of urethane resins, acrylic resins, polysiloxane resins, fluorine resins, and melamine resins is preferably uniformly dispersed in water.

The deodorant is 0.1 to 2% of zinc oxide, 0.1 to 0.5% of silver, 0.1 to 2% of silica and 5 to 20% of the binder resin is uniform in the remaining amount of water to make the total amount of the deodorant to 100% To be dispersed or dissolved. If the content of zinc oxide, silver, and silica is used below the above range, there is a concern that the deodorizing property may not be sufficient, and if it exceeds the above range, it is difficult to obtain a uniformly dispersed deodorizing agent. When the content of the binder resin is less than the above range, it is difficult to effectively attach the deodorant to the acetate fiber, and when the content exceeds the above range, there is a problem that the physical properties such as the stiffness of the acetate fiber becomes stiff.

The zinc oxide is preferably about 0.1 to about 10 ㎛ average particle size. If the average particle diameter is less than about 0.1 μm, the effect is excellent, but there is a problem that the product price rises sharply. If the average particle diameter exceeds about 10 μm, it is difficult to manufacture the processing liquid and the touch of the deodorant fabric is hardened. Zinc oxide is a white powder obtained from metal zinc. It is non-toxic and is an inorganic substance used as a raw material for white pigments, pharmaceuticals, and cosmetics, and can be chemically decomposed by oxidizing organic substances such as odors.

The silver powder preferably has an average particle size of about 10 nm to about 100 nm. If the average particle diameter is less than about 10 nm, the effect is excellent, but the product price is rapidly increased, there is a problem in commercialization, if it exceeds about 100 nm, there is a problem in dispersibility when preparing the processing liquid. The silver powder may be added to the deodorizing agent as it is, but may be commercially available as a colloidal liquid in a sol state. Using colloidal silver has the advantage of better dispersibility. Silver powder acts as an antimicrobial to remove the odor generated by the bacteria.

The silica powder is a colorless transparent solid, preferably porous silica having an average particle size of about 0.1 to about 10 μm. If the average particle diameter is less than about 0.1 ㎛ exhibits an excellent effect by increasing the surface area, but there is a problem that the price rises, and if it exceeds about 10 ㎛ there is a problem that the durability of the laundry is lowered. Porous silica powder is a fine pore to collect the odor component.

As the binder resin, a polymer resin selected from the group consisting of urethane resins, acrylic resins, polysiloxane resins, fluorine resins and melamine resins can be preferably used. Industrially water-soluble polyurethane resins are particularly preferable in terms of imparting a soft touch to the deodorizing fabric. Do.

It is preferable that the average particle size after mix | blending a deodorant is about 10 micrometers or less. When the average particle size of the deodorizing agent exceeds about 10 ㎛, the dispersion state of the processing agent is lowered, processing efficiency is lowered, and it is difficult to form a durable bond with the acetate fiber.

The deodorant processing agent used in the present invention having the above-described constitution can exert excellent deodorizing properties to the acetate fibers by synergistic effect of the deodorizing components of zinc oxide, silver and silica. In addition, when the acetate fiber is processed using the deodorant processing agent, not only the excellent deodorant characteristics but also the laundry durability of the deodorant characteristics, almost no change in color before and after processing, and have excellent mechanical properties and various fastnesses.

Next, the compounding method of the deodorizing agent used by this invention is demonstrated.

First, 0.1 to 2% of zinc oxide powder, 0.1 to 0.5% of silver powder, 0.1 to 2% of silica powder and 5 to 20% of urethane resin are added to water in an amount of 100% of the total composition, and about 5 to about Stir for 10 hours. Then, it is possible to obtain a deodorizing agent having a small particle size distribution in which each of the above components is uniform in water and has an average particle size of about 10 μm or less.

(2) Impregnation and drying process of deodorizing agent to acetate fiber

The dyed acetate fibers are then impregnated into the deodorant and dried. This allows the deodorant to penetrate into the amorphous region of the acetate fibers. Subsequently, the dried acetate fiber is heat-treated to fix the active ingredient of the deodorizing agent to the amorphous region of the acetate fiber.

The acetate fibers include 100% acetate fibers as well as rayon fibers, cotton fibers, wool fibers, hemp fibers, polyester fibers, nylon fibers, acrylic fibers, PVA fibers, polyvinylchloride fibers, polyvinylidene chloride fibers and modacryl fibers. It is to be understood that it also includes fibers selected from the group consisting of acetate fibers and mixed fibers. The acetate fiber is a concept that includes not only cellulose triacetate rayon fiber but also cellulose acetate rayon obtained by partially hydrolyzing an acetate group thereof.

Although the said rayon fiber is not specifically limited, The high-performance viscose rayon etc. which are marketed by brand names, such as a cordura, tenasco, a durafil, as well as general-purpose viscose rayon, polynosic rayon, copper ammonium rayon, are mentioned as a specific example.

Although the said polyester fiber is not specifically limited, A polyethylene terephthalate fiber, a polytrimethylene terephthalate fiber, a polybutylene terephthalate fiber, etc. are mentioned as a specific example.

Specific examples of the nylon fibers include aliphatic polyamide fibers such as nylon 6, nylon 66, nylon 610 and nylon 612, as well as aromatic polyamide fibers sold under trade names such as Kevlar and Nomex.

The acrylic fiber is obtained by polymerizing a monomer system formed by mixing one or two kinds of vinyl monomers such as at least 85% of acrylonitrile and the remaining amount of methyl acrylate, methyl methacrylate, vinyl acetate or sodium p-styrenesulfonate. It will not specifically limit, if it is a fiber manufactured from a polymer.

The modacryl fiber is not particularly limited as long as it is a fiber made from a polymer obtained by polymerizing a monomer system formed by mixing 35 to 85% of acrylonitrile and one or two of vinyl chloride, vinylidene chloride, and vinyl bromide. Do not.

The acetate fibers may be in any shape, such as yarn, woven fabric, knitted fabric or nonwoven fabric, but in the case of deodorizing in a continuous manner using a tenter or the like, the acetate fibers are preferably in the shape of knitted fabric or nonwoven fabric.

In the impregnation process, the dyed acetate fiber is impregnated with the deodorant agent of about 5 to about 20 times its own weight, and then the pick-up rate of the deodorant agent is about 50 to Adjusted to be about 80%. The impregnated acetate fibers are then dried at about 90 to about 120 ° C. for about 1 minute to about 10 minutes.

(3) heat treatment step

The dried acetate fibers are then heat treated at about 120 to about 180 ° C. for 1 to 10 minutes. Thereby, the active ingredient of the deodorizing agent impregnated in the amorphous region of the acetate fiber is fixed by the binder. Finally, the deodorized finished acetate fibers are washed with water at about 10 to about 50 ° C. and dried.

The drying and heat treatment step of (2) and (3) may be carried out in a separate process or may be carried out at the same time.

First, the drying and heat treatment steps will be described as separate steps.

That is, using a tenter (drying and heat treatment) at about 90 to about 120 ℃ for about 1 minute to about 10 minutes, more preferably from about 2 minutes to about 4 minutes to completely remove the moisture present inside the fiber Remove it. If the temperature is too low or dried for a short time, there is a fear that the heat treatment may not be effectively performed after the moisture inside the fiber is not completely removed. In addition, if the temperature is too high or dried for a long time, the deodorization rate may be lowered. In this case, the tenter preferably has 4 to 6 drying chambers. The dried fiber is heat-treated using the tenter again at about 120 to about 180 ° C. for about 1 to about 10 minutes, more preferably about 2 to about 4 minutes, thereby firmly attaching the deodorizing agent to the fiber. As in the drying step, if the heat treatment for too low temperature or for a short time does not adhere to the fiber effectively, there is a fear that the laundry durability of the deodorant properties are poor. In addition, the fiber may become brittle if the temperature is too high or heat treatment for a long time. When the heat treatment is completed, the deodorized acetate fiber is washed with water at about 10 to about 50 ° C. and dried.

As described above, in the deodorizing process of the present invention, it is preferable that the fibers are completely dried and then heat treated. However, the drying and the heat treatment may be performed simultaneously. In this case, the acetate fiber impregnated with the deodorizing agent is used for about 1 minute to about 20 minutes, more preferably about 2 to about 10 minutes, most preferably about 2 minutes to about 120 to about 180 ° C using a tenter. It is subjected to drying and heat treatment at the same time for about 4 minutes, but the deodorizing property may be slightly lower than that of the fiber which is completely dried and then heat treated. After the drying and heat treatment are completed, the deodorized acetate fiber is washed with water and dried in water at about 10 to about 50 ° C.

Hereinafter, the deodorizing processing method of the acetate fiber of the present invention will be described in more detail with reference to Examples and Comparative Examples.

Referring to Table 1, in Examples 1, 2, and 3 according to the present invention, which were deodorized by a compound prepared using zinc oxide, silver, silica, and urethane resin, the deodorization ratios were all 86% to 93%. When the processing agent is not treated (Comparative Example 1); When processed with a compound prepared except any of zinc oxide, silica or urethane resin (Comparative Examples 2, 3, 4); And when treated with beta-cyclodextrin used as a deodorant (Comparative Example 5).

When processed with the formulation prepared except the urethane resin used as a binder (Comparative Example 4), after 20 times dry cleaning, the degree of deodorization decrease is large, it can be seen that the laundry durability is poor. On the other hand, in Examples 1 to 3 according to the present invention, the retention rate of the deodorizing property was high even after 20 times of dry cleaning, so that the durability of washing was excellent. I could see. At this time, if the color difference is less than 1.5, it means that the color is not changed because it is not recognized by the human eye. In the case of fastness, grades 4-5 are lower than grade 5, but are considered excellent grades considering the fastness of commercial textile products.

When the results of Example 2 were compared with those of Example 1, it was confirmed that the deodorization rate was better when the concentrations of zinc oxide, silver, and silica used as the deodorant were increased. In the case of Example 3, which was simultaneously dried and heat treated during the deodorizing process, the deodorizing property and the fastness were slightly lowered.

1 and 2 show scanning electron microscope (SEM) photographs after deodorizing and deodorizing 20 times after deodorizing the acetate fiber according to Example 1, respectively. 1 is a SEM photograph at 1000 times magnification after deodorization, and FIG. 2 is a SEM photograph at 1000 times magnification after 20 times of dry cleaning. Comparing FIG. 1 with FIG. 2, it can be seen that the processing agent is attached to the fiber not only after the deodorizing process but also after 20 dry cleanings, and it can be confirmed again that there is washing durability.

As described above, according to the deodorizing processing method of the acetate fiber of the present invention, by preparing a mixture containing zinc oxide, silver, silica, urethane resin and the like, the color before and after processing by impregnating, drying, and heat treating the acetate fiber However, it is possible to obtain a product exhibiting excellent deodorizing properties with durability of washing without changing mechanical properties. In particular, it is excellent in sweat fastness and can remove odors such as sweat, thereby contributing to the production of high value-added functional acetate fiber products.
