Embodiment 1

[0028] The preparation of textile compound antibacterial agent of the present invention:

[0029] Step 1: Wash the soybeans, add 3 times the weight of pure water, soak them at 40°C for 24 hours, peel them, and then use a crushing device to crush them into a slurry;

[0030] Step 2: filter the above muddy substance with 80 mesh filter cloth to obtain white emulsion;

[0031] Step 3: Add 4 times the volume of pure water to the white emulsion, then add 800mg / L chitosan (average molecular weight 7.3×10 5 Da, deacetylation degree 87%) for flocculation, after filtration and separation, a transparent liquid was obtained;

[0032] Step 4: After diluting the above transparent liquid (soybean extract) 50 times, add 1% N-dodecyl-β-alanine sodium, 1% Tween-80, 0.5 % methyl acrylate polymer (molecular weight is 2580Da), 0.4% 3-(trisilanol) propyl dimethyl octadecyl ammonium chloride, the balance is water, and the textile composite antibacterial compound of the present invention can be o...

[0035] The preparation of textile compound antibacterial agent of the present invention:

[0036] Step 1: Wash the soybeans, add 2 times the weight of pure water, soak them at 30°C for 48 hours, peel them, and then use a crushing device to crush them into a slurry;

[0037] Step 2: filter the above-mentioned muddy substance with a 60-mesh filter cloth to obtain a white emulsion;

[0038] Step 3: Add 5 times the volume of pure water to the white emulsion, then add 1500mg / L chitosan for flocculation, filter and separate to obtain a transparent liquid;

[0039] Step 4: After diluting the above transparent liquid (soybean extract) 40 times, add 2% N-dodecyl-β-alanine sodium, 2.5% Tween-80, 2 % methyl acrylate polymer (molecular weight is 2580Da), 0.1% 3-(trisilanol) propyl dimethyl octadecyl ammonium chloride, after completely dissolving, obtain the composite antimicrobial agent for textiles of the present invention.

[0040]

Embodiment 3

[0042] The preparation of textile compound antibacterial agent of the present invention:

[0043] Step 1: Wash the soybeans, add 3 times the weight of pure water, soak them at 60°C for 12 hours, peel them, and then use a crushing device to crush them into a slurry;

[0044] Step 2: filter the above-mentioned muddy substance with a 160-mesh filter cloth to obtain a white emulsion;

[0045] Step 3: Add 6 times the volume of pure water to the white emulsion, then add 1000mg / L chitosan (average molecular weight 7.3×10 5 Da, deacetylation degree 87%) for flocculation, after filtration and separation, a transparent liquid was obtained;

[0046] Step 4: After diluting the above transparent liquid (soybean extract) 50 times, add 0.05% N-dodecyl-β-alanine sodium, 0.5% Tween-80, 0.5 % methyl acrylate polymer (molecular weight is 2580Da), 4% 3-(trisilanol) propyl dimethyl octadecyl ammonium chloride, promptly obtain textile compound antibacterial agent of the present invention after dis...

Abstract

The invention discloses a textile composite antibacterial agent and a preparation method thereof. The textile composite antibacterial agent with high safety and strong antibacterial capability and broad-spectrum antibacterial action is obtained by uniformly mixing a soybean extract, a zwitterions surfactant of sodium N-lauryl-Beta-amino propionate, a methyl acrylate polymer, a nonionic surfactant of Tween-80 and 3-(trisilanol) propyl dimethyloctadecyl ammonium chloride.

Description

technical field [0001] The invention relates to the preparation of an antibacterial agent, in particular to a composition of a textile composite antibacterial agent and a preparation method thereof. [0002] Background technique [0003] Preventing pathogenic bacteria from invading the human body is one of the key measures to prevent the occurrence and prevalence of infectious diseases, and effectively avoiding or reducing the contact between the human body and pathogenic bacteria is an important way to reduce the chance of being infringed. [0004] Infectious diseases caused by pathogenic microorganisms have always been a major threat to human health since human social activities began. In the past 20 to 30 years, the incidence of infectious diseases has increased significantly, and some unheard of severe infectious diseases have continued to break out and become popular. Some infectious diseases that were once effectively controlled have revived around the world. Accordi...
