manufacture example 1

[0030] Dissolve the acrylonitrile polymer composed of 91.1% of acrylonitrile, 8.6% of methyl acrylate and 0.3% of sodium methallylsulfonate prepared by conventional polymerization in 45% of sodium thiocyanate (Rodanso- Da) aqueous solution to prepare a spinning dope with a polymer concentration of 12%. Use a known spinneret to extrude the stock solution into a 10% sodium thiocyanate aqueous solution at -3°C, wash with water, stretch, and heat-treat to make acrylic fiber (fiber A), and then, for the fiber Introduce silver into the medium, use 1% nitric acid aqueous solution to adjust 1000ml of silver nitrate aqueous solution adjusted to 20m·mol / l to pH3, put 100g of fiber A into the solution, treat at 98°C for 10 minutes, wash with water, dry, then put into In 1000 ml of sodium oxalate aqueous solution adjusted to 10 m·mol / l, it was treated at 98° C. for 10 minutes, washed with water, and dried to prepare an acrylic fiber (fiber B) containing a silver compound.

manufacture example 2

[0032]Except using AN95%, the acrylonitrile polymer of vinyl acetate 5% composition, with the treatment time of silver nitrate aqueous solution being 30 minutes, other make the acrylonitrile fiber manufacture example 1 that contains silver compound similarly to contain silver acrylic fiber (fiber C) based on a compound.

[0033] After soaking the acrylic fibers (fibers B and C) containing silver-based compounds prepared above in an aqueous solution whose pH is adjusted with nitric acid, remove the moisture, put them into an autoclave (when the heat treatment temperature exceeds 100°C) or dry them with hot air. machine (when the heat treatment temperature is below 100°C), heat treatment is carried out at the pH and temperature shown in Table 1, and six kinds of fibers of fiber No. 1-5 and 8 are made, and fiber No. 6 and 7 are silver-containing compounds respectively. The acrylic fiber (fiber A) of Production Example 1 and the acrylic fiber (fiber B) itself containing a silver-b...

Embodiment 1

[0048] Embodiment 1, comparative example 1

[0049] As the silver-loaded acrylic fiber, the above-mentioned fiber No. 2 was 10% by weight, the acrylic fiber "K85-1.3T51" manufactured by Nippon Exchlan Industry Co., Ltd. was 40%, and the water-absorbent acrylic fiber "K626-1.7" manufactured by the company was T51 " 50% by weight is blended, spins out the monofilament of metric count 1 / 10S according to the common method of spinning and weaving of synthetic fiber 2 inches, after continuing double-filament processing, makes the yarn of weight 250g according to creel perimeter 200cm. The yarn was bulked at 100° C. for 15 minutes in an atmospheric box type steam treatment apparatus. The bulky yarn is rewound, and the weight per unit area is about 600g / m with a 3-gauge automatic flat knitting machine 2 Plain weave knitted fabric sample (Example 1). In Comparative Example 1, a knitted fabric sample was prepared in the same manner as in Example 1, except that the silver-carrying acry...

Abstract

Provided is a fibrous structural material having an anti-trichophyton activity against trichophyton which is a kind of fungus, and further having an anti-trichophyton spore activity against the spores of the trichophyton. This anti-trichophyton fibrous structural material contains a silver-loaded acrylonitrile-based fiber obtained by heat-treating the acrylonitrile-based fiber containing a silver-based compound in pH 1-6 range, as an active ingredient. The anti-trichophyton fibrous structural material has an excellent anti-trichophyton activity against the trichophyton, and further anti-trichophyton spore activity against the spores of the trichophyton. Further it has an anti-bacterial property against bacteria, and in addition, a so-called photo-catalytic activity function capable of improving the antibacterial activity by the irradiation of light.

Description

[technical field] [0001] The present invention relates to an anti-white tinea fiber structure in which silver-loaded acrylic fibers are an active ingredient. [Background technique] [0002] Trichophyton is a kind of fungus, is the pathogenic bacterium of beriberi, takes human or animal chitin protein as nutrition source and parasitizes on skin, hair, claw etc. Many people are very troubled by this disease now, and expect that there will be anti-phytophyte fiber products. In particular, since Trichophyton is fond of high temperature and high humidity, it is often detected from floor mats in bathrooms. Because this white tinea fungus survives for a long time by forming spores, it becomes the source of infection of beriberi in the family. Therefore, there is a desire for a fiber product that is effective against spores of Trichophyton spp. and has anti-Tychophyton spores. [0003] Therefore, as a method of imparting anti-white ringworm property to fibers, a method of imparti...
