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

[0029] (1) Take the nutrient solution in the fermenter, add 1-4% yeast powder into the fermenter, stir and mix, and ferment at a constant temperature of 28-32°C for 12-20 days. During the fermentation process, every Add pretreated loofah with 6-10% of the total mass of materials in the fermenter every 3-5 days. After the fermentation is completed, heat and sterilize at 90-100°C for 12-20 minutes to obtain the fermented material. Take the fermented material according to the mass ratio of 20-20 30:3~7:1 Add the reagent, mix the hexacyclite passing through the 120 mesh sieve for 30~55min, move it into the ultrasonic oscillator, and oscillate ultrasonically for 25~40min at the ultrasonic frequency of 45~50kHz to obtain the dispersion, take the dispersion Suction filtration, collect the filter residue and treat it in a freeze dryer at -20~-10°C for 4~8 hours to obtain a freeze-dried materi...

Embodiment 1

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

[0038] Regulator: At 30°C, take fatty alcohol polyoxyethylene ether and add 12% triethanolamine solution in a mass ratio of 3:15 to mix to obtain a mixed solution. Take the mixed solution and add hydroxyethyl cellulose in a mass ratio of 10:1:2 Mixing element and polylactic acid to obtain regulator.

[0039] Additives: At 20°C, take casein and add hexamethylenetetramine and water in a mass ratio of 7:1:30 to mix, heat up to 65°C, keep stirring for 25 minutes, heat up to 70°C, add caprolactam with 25% casein mass Mix and stir for 35 minutes, and cool naturally to room temperature to obtain the reaction material. At 30°C, take the reaction material and add carbamate in a mass ratio of 12:1 and mix to o...

Embodiment 2

[0053] Nutrient solution: in parts by weight, mix 3 parts of agar, 10 parts of bagasse powder, 15 parts of wort juice, 4 parts of yeast extract, 4 parts of glucose, 4 parts of potassium dihydrogen phosphate, 4 parts of casein, and 900 parts of water, That is the nutrient solution.

[0054] Regulator: At 40°C, take fatty alcohol polyoxyethylene ether at a mass ratio of 7:15 and add triethanolamine solution with a mass fraction of 12% for mixing to obtain a mixed solution. Take the mixed solution and add hydroxyethyl cellulose at a mass ratio of 10:4:5 Mixing element and polylactic acid to obtain regulator.

[0055] Additives: At 40°C, take casein and add hexamethylenetetramine and water in a mass ratio of 10:1:40 to mix, heat up to 75°C, keep stirring for 50 minutes, heat up to 85°C, add caprolactam with 40% casein mass Mix and stir for 60 minutes, cool naturally to room temperature to obtain the reaction material, at 45°C, take the reaction material and add carbamate at a mas...

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...
