Example Embodiment

[0028] The preparation method of composite acrylic fiber base material includes the following steps:

[0029] (1) Take the nutrient solution in the fermenter, and add the yeast powder with 1~4% of the nutrient solution quality to the fermenter, stir and mix, and let stand at a constant temperature of 28~32℃ for 12~20 days. During the fermentation process, every Add the pretreated loofah with 6~10% of the total mass of the materials in the fermentor every 3~5 days. After the fermentation is over, heat and sterilize at 90~100℃ for 12~20min to obtain the fermented material. Take the fermented material according to the mass ratio of 20~ 30:3~7:1 Add reagents and mix with the six-ring stone that has passed through a 120-mesh sieve for 30~55min, move it into an ultrasonic oscillator, and vibrate ultrasonically for 25~40min at an ultrasonic frequency of 45~50kHz to obtain a dispersion, and take the dispersion Suction filtration, collect the filter residue and treat it in a freeze dryer ...

Example Embodiment

[0036] Example 1

[0037] Nutrient solution: Take 1 part agar, 8 parts bagasse powder, 10 parts wort, 2 parts yeast extract, 2 parts glucose, 2 parts potassium dihydrogen phosphate, 1 part casein, and 700 parts water in parts by weight. Get the nutrient solution.

[0038] Conditioning agent: At 30℃, take fatty alcohol polyoxyethylene ether according to the mass ratio of 3:15 and add 12% triethanolamine solution and mix to obtain a mixed solution. Take the mixed solution and add hydroxyethyl fiber according to the mass ratio of 10:1:2. Mixing of vegetarian and polylactic acid, the regulator is obtained.

[0039] Additives: At 20°C, take casein, add hexamethylenetetramine and water at a mass ratio of 7:1:30, heat up to 65°C, keep stirring for 25min, heat up to 70°C, add caprolactam with 25% casein mass Mix and stir for 35 minutes and cool to room temperature naturally to obtain a reaction material. At 30° C., take the reaction material and add the carbamate to the mixture at a mass r...

Abstract

The invention discloses a complex antibacterial acrylic fiber, and belongs to the technical field of preparation of special synthetic fibers. According to the complex antibacterial acrylic fiber, saccharomycete is adopted for fermentation, in the process, loofah sponge is supplemented, through the cooperation of plant fibers and bacterial fibers which both are subjected to enzymolysis and fermentative degradation treatment, a fiber adsorption film is formed, disadvantage factors can be combined with negative ions to be adsorbed by the synthetic fiber film with good adsorption performance, andthus a stable bacteriostatic effect is provided; methyl methacrylate, acrylic acid and the like are taken as monomers and the like and prepolymerized to form emulsion with film-forming performance, then adipic dihydrazide is added to form stable emulsion, hydrophilic groups generate inner crosslinking on the molecular structure, and the stability of water resistance is improved; casein is taken asa raw material of an additive for modification, and can be better combined with macromolecule water-resistance components and synthetic fiber components, and the water resistance effect and the retaining performance on the antibacterial components are reinforced. According to the complex antibacterial acrylic fiber, the problems that the water resistance of antibacterial acrylic fibers which arecommonly used at present is poor, antibacterial components in the fibers easily shed during washing, and thus the antibacterial effect is weakened are solved.

Description

technical field [0001] The invention relates to a composite antibacterial acrylic fiber, which belongs to the technical field of preparation of special synthetic fibers. Background technique [0002] Acrylic fiber is soft to the touch and known as "artificial wool". More and more attention is paid to the health care function of fabrics, among which antibacterial fabrics with bactericidal or antibacterial functions are very popular, such as antibacterial underwear, antibacterial socks, etc. Antibacterial fabrics are usually made of antibacterial functional fibers with antibacterial properties. Acrylic fibers have good warmth retention and moisture permeability, and are easy to blend with wool and cotton. They are suitable for making underwear, socks and other close-fitting fabrics. Therefore, antibacterial acrylic fibers are very The development of ideal antibacterial functional fibers has also attracted much attention. At present, the methods of manufacturing antibacterial...
