Abstract

PURPOSE:To obtain a deodorant antimicrobial fiber material not irritating skin, having excellent fitness to skin. CONSTITUTION:Fibers are treated with a fiber treating agent obtained by combining a protein material such as collagen with a fiber treating agent, or silk fibroin is used instead of collagen to readily provide a product having appearance of natural silk which has been regarded difficult to make.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a functional fiber and a fiber product, and more particularly to a fiber material and a fiber product treated with a fiber treating agent containing chitosan and a polypeptide.

[0002]

2. Description of the Related Art It is well known that recent advances in fiber materials have been remarkable and various new fiber materials have been developed. However, the characteristics of natural fiber materials, especially the texture of silk and cotton, water absorption, etc. Such properties are irreplaceable, and many attempts have been known to impart the properties of these natural fiber materials to synthetic fiber materials, but satisfactory results have not yet been obtained.

[0003]

The present invention therefore has the properties of natural and synthetic fiber materials,
Moreover, it is intended to obtain various fiber materials and fiber products having excellent texture, strength and hydrophilicity of which functional characteristics can be easily and arbitrarily changed, and a novel fiber treatment agent therefor. To provide.

[0004]

As a result of continuous research on the characteristics of various fiber materials for textile products, the present inventors have found that
Based on chitosan and polypeptides, we found that adding a reactive resin to them did not impair the feel of textiles, but rather markedly improved dyeing and dyeing properties. By combining protein materials, we succeeded in obtaining novel fiber materials and fiber products having excellent texture, dyeability, and dyeability as well as strength and hydrophilicity.

According to the present invention, a combination of chitosan and a polypeptide is further combined with a reactive resin such as silicon and urethane, and a bactericide, a deodorant and a dyeing agent are added to the mixture to treat various fibers and fiber products. To do.

The polypeptide used in the present invention, particularly collagen, accounts for 1/3 of the total protein weight of the human body and is indispensable for the human body and has an excellent moisturizing effect. Chitosan is a crustacean or fungus. It is a polysaccharide of a natural polymer extracted from, etc., has sterilization and deodorant properties, and since both are components that are well suited to the human body, especially to the bare skin, in the medical field, artificial skin and surgical suture thread are also used. In the food field, it is already widely used as a plant fiber health food and a food storage stabilizer, and it has excellent moisture retention, antibacterial properties, deodorant properties, water absorption, durability, and safety. It is characterized by its soft texture and can be used as a woven or knitted material such as cotton, polyester, nylon, etc., as a material for underwear, bedding, uniforms, stockings and the like.

Further, in the present invention, by using silk protein (quibroin) as a polypeptide instead of collagen, it is possible to obtain a fiber material and a fiber product having an appearance very similar to that of silk, which is multifaceted according to the product application. Product deployment is possible

EXAMPLES Examples of the present invention will be shown below, but it should be understood that these examples are only for facilitating the understanding of the present invention and do not limit the present invention. .

Example 1 A polyester original fabric was CAP (Calfa Chemical Co.) 20
20% double dilution solution, 1% chitosan aqueous solution (Kataoka Tickerin CTA-1, lactic acid) 50%, Collagen W-52 (Seiwa Kasei) 20%, Dime Shoe 5002 (Dainichi Seika Kogyo)
As a result of treatment with a mixed solution of 10% of the treatment liquid of the present invention and Marvas (manufactured by Komatsu Seiki) so that 5% of the cloth weight was adhered, this treated product was as good as Marvas Medical. It has excellent durable water absorption, durable SR property, durable antistatic property, and durable antibacterial property.

Example 2 Nylon pantyhose was diluted with CAP (Calfa Chemical Co., Ltd.) 10 times diluted solution 10%, 1% chitosan aqueous solution (Kimitsu Chemical LLWP, lactic acid) 20%, collagen W-
42 (Seiwa Kasei) 5%, Dime Shoe 5002 (Dainichi Seika Kogyo) 5%, Aminosilicon PS-2 50%, water 1
The product treated with 0% of the treatment liquid of the present invention showed excellent antibacterial properties after washing 10 times.

Example 3 Tencel (cellulose fiber) was subjected to padding treatment with a 10-fold dilution of the treatment liquid of the present invention and 80% squeezing, followed by a dry heat treatment at 160 ° C. for 2 minutes. A broth suspension of test bacteria was added to this sterilized sample, and the viable cell count after culturing at 37 ° C. for 18 hours in a closed container was measured. .2, and the difference between the increased and decreased values was 5.4.

Example 4 CAP 10-fold diluted solution 10%, 1% chitosan aqueous solution (Kimitsu Chemical LLWP, lactic acid) 20%, collagen W-42
(Seiwa Kasei) 5%, Dime Shoe 5002 (Dainichi Seika Kogyo) 5%, Amino Silicon W (Ohara Palladium) 50
%, 10% water to dilute the treatment liquid of the present invention 10 times with water, and perform a padding treatment on the woolen fabric.
After drying at 30 ° C., antibacterial test (after 10 times of dry washing), deodorizing test (after 10 times of dry washing), and antistatic test (after 3 times of dry washing) were performed. The test results by the Japan Spinning Inspection Association showed excellent results.

Example 5 CAP 10-fold diluted solution 10%, 1% chitosan aqueous solution (Kimitsu Chemical LLWP, lactic acid) 20%, collagen W-42
(Sowa Kasei) 5%, Dime Shoe 5002 5%, Viplet SV (Bayer aqueous urethane) 30%, PORON SR-CONC (Shin-Etsu Chemical, hydrophilic silicone oil) 10
% And 20% of water, the treatment solution of the present invention was diluted 10 times with water to dip the cotton fabric. Excellent results were obtained in antibacterial properties, deodorizing properties, water absorption properties, and moisture release properties.

[0014]

As described above, according to the present invention, since collagen, chitosan and other natural materials of the same quality as human bare skin are used, moisturizing and sterilizing without causing any damage to the skin, Deodorization can be achieved. Further, by using silk protein instead of collagen in the present invention, it has become possible to obtain a fiber material and a fiber product having the advantages of silk, synthetic fiber and cotton, which have been heretofore difficult.
