Embodiment 1

[0018] Embodiment 1: 2.7 kilograms of chitosan (molecular weight 5~70,000), 1.6 kilograms of acetic acid (by 100%), 15.3 kilograms of diaminosilicone oil (ammonia value 0.3), cetyl benzyl dimethyl ammonium bromide 1.2 kg, 1.5 kg of low-temperature self-crosslinking polyacrylate adhesive, 0.5 kg of acetic anhydride, 0.7 kg of butane tetraacid crosslinking agent, 4 kg of ethanol, and 72.5 kg of water.

[0019] The preparation process is to first dissolve chitosan in the water-alcohol mixture containing an acidifying agent, stir it into a fluid colloid, and then add amino silicone oil, adhesive, cross-linking agent, and acetic anhydride auxiliary agent sequentially under stirring, and stir evenly , ripen and serve.

Embodiment 2

[0020] Embodiment 2: 1.2 kilograms of quaternized chitosan, 0.6 kilogram of acetic acid (by 100%), 0.4 kilogram of citric acid, 8 kilograms of amino silicone oils, 1 kilogram of dodecyl benzyl dimethyl ammonium chloride, butane 0.9 kg of four-acid crosslinking agent, 0.5 kg of sodium hypophosphite, and 87.8 kg of water.

[0021] Dissolve quaternized chitosan in water first, then add acetic acid, citric acid, amino silicone oil, cross-linking agent and other auxiliary agents sequentially under stirring, stir evenly, and mature.

Embodiment 3

[0022] Embodiment 3: 1.8 kilograms of chitosan, 0.5 kilogram of quaternized chitosan, 1 kilogram of acetic acid (by 100%), 12 kilograms of amino silicone oils, 0.5 kilogram of dodecyl benzyl dimethyl ammonium chloride, butyl 1 kg of alkane tetraacid crosslinking agent, 0.4 kg of citric acid, 0.5 kg of sodium hypophosphite, and 82.3 kg of water.

[0023] Dissolve chitosan in water containing an acidulant, stir to form a fluid colloid, then add quaternized chitosan and stir to dissolve, then add amino silicone oil, cross-linking agent, catalyst and other auxiliary agents sequentially under stirring, and mature become.

Abstract

The present invention is chitin-based biomembrane finishing agent for fabric and its preparation process and application process. The present invention features that the biomembrane finishing agent has chitin derivative as the main antiseptic component, and may includes chitin, chitinamine, chitosan, carboxymethyl chitosan and quaternarized chitosan. The biomembrane finishing agent has water or alcohol as solvent and has concentration of 0.02-20 wt%. The preparation process includes dissolving chitin or its derivative in water with acidifying agent or alcohol to form flowable colloid, adding assistants via stirring and maturing. The treated fabric has chitin-based biomembrane formed and thus has antiseptic, water-absorbing and moist maintaining functions.

Description

technical field [0001] The invention relates to a textile finishing agent mainly containing chitin derivatives for producing antibacterial, antibacterial deodorant, antibacterial health care or antibacterial skin care functional textiles, specifically a chitin-based biofilm finishing agent suitable for textiles ( (referred to as JKMO finishing agent) and its preparation and application process. Background technique [0002] The outbreak of SARS (SARS) not only caused great losses to the national economy, but also seriously damaged people's physical and mental health. Facing the sudden outbreak of the epidemic, the Chinese government put forward the slogan "To defeat SARS depends on science and technology". Experts at home and abroad have also put forward the strategic thinking of "prevention is more important than cure" for the long-term prevention and treatment of SARS. In real life, people will inevitably come into contact with various microorganisms such as bacteria and...
