example 1

[0017] First, in parts by weight, take 40 parts of agar, 30 parts of yeast extract, 18 parts of starch, 1 part of disodium hydrogen phosphate, 0.8 part of sodium dihydrogen phosphate and 16 parts of sucrose, stir well, and use a mass fraction of 20% phosphoric acid Adjust the pH of the solution to 6.0, and sterilize it under an ultraviolet lamp to obtain the culture medium. Streptomyces is inoculated on the culture medium according to the inoculum size of 10%; then the above inoculated culture medium is moved to a constant temperature box, and Set the temperature at 28°C, the rotational speed at 160r / min, cultivate for 18 hours, rinse the surface of the culture medium with sterile water until there is no mycelium on the surface of the culture medium, collect the eluent, and obtain a suspension of mycelia, according to the mass ratio of 5:2: 1:1, take mycelia suspension, starch, emulsifying oxidase and sodium hydrosulfide into a mixer, and mix evenly at 50°C to obtain a modified...

Abstract

The invention discloses a preparing method of high-water-absorption antibacterial acrylic fiber, and belongs to the field of acrylic fiber preparation. The provided preparing method includes the steps that a culture medium is inoculated with streptomycete, modified hyphae are obtained through screening and modifying, then the modified hyphae are mixed with starch and the like to prepare a modified matrix, the modified matrix is mixed with polyacrylonitrile and formaldehyde, the pH value is adjusted, N,N-methylene bisacrylamide is used as initiator for carrying out graft modification reaction, air is exhausted, the product is stirred and cooled to the room temperature, and then the high-water-absorption antibacterial acrylic fiber is obtained through discharging, drying, curling, cutting and packaging. The method is unique and novel, as the microorganism is added to serve as antibiont, starch is modified for graft modification, the prepared acrylic fiber has high water absorption and antibacterial performance, and own defects of the acrylic fiber are overcome; the preparing process is simple and easy to implement, the raw materials are simple and easy to obtain, cost is low, and the acrylic fiber is suitable for large-scale application and popularization.

Description

technical field [0001] The invention discloses a preparation method of highly water-absorbing antibacterial acrylic fiber, which belongs to the field of acrylic fiber preparation. Background technique [0002] Acrylic fiber is the trade name of polyacrylonitrile fiber in our country. Acrylic has excellent performance, soft and warm to the touch, and has good elasticity. Light fastness and weather resistance are particularly good. Generally made into short fibers. Can be spun pure or blended with wool. It is used to make textiles, knitwear, blankets, tents, curtains and filter cloths, etc. Because its properties are close to wool, it is called "synthetic wool". Flat acrylic fiber is a kind of acrylic fiber whose cross-section is rectangular or close to rectangular. Flat acrylic fiber has special luster, bulkiness and anti-pilling performance, and has good post-processing effect. It feels like touching feathers and animal fur, so it is mainly used as artificial fur, plush...
