Antibacterial mechanism Organic quaternary ammonium salts have excellent antibacterial and antibacterial properties, which have been proven through practice. Studies have shown that using it for the finishing of pure cotton fabrics, it was found that the inhibition rates of Staphylococcus aureus, E. coli and Candida albicans reached 98.12%, 96.86% and 95.14% after 24 hours, showing a broad-spectrum antibacterial effect. It has a high antibacterial rate, and is safe, non-toxic and non-enzyme. Huang Zuoxin [3] studied the adsorption performance of polysiloxane with side groups of benzyldimethylsilylammonium chloride on pure cotton bedding and its bactericidal activity against Escherichia coli and Staphylococcus aureus. The results show that the bactericidal activity is very strong. The Japanese patent reports the use of trimethoxysilyl substituted isocyanurate compounds, trimethoxysilane containing C 10-30 quaternary ammonium group (quaternary ammonium group) and CH 2 Cl 2 as finishing agents to treat polyester Fabric. After heat treatment at 100°C for 10 minutes, the fabric has excellent antibacterial and washing resistance. Organic silicon quaternary ammonium salt (quaternary ammonium salt) is a new type of cationic surfactant. It has high temperature resistance, washing resistance and long-lasting effects. It has a wide range of antibacterial properties and can effectively inhibit Gram-positive bacteria, Gram-negative bacteria, yeasts and fungi. . Its bactericidal mechanism is: using organosilicon as a medium, the ammonium cation group with bactericidal properties is strongly adsorbed on the surface of the bacteria, changing the permeability of the bacterial cell wall, and overflowing enzymes, coenzymes and metabolic intermediates in the bacteria. Make the microorganisms stop breathing and die, so as to achieve the effect of sterilization and bacteriostasis, that is, “contact death” occurs. In the structure, R is an active group, such as OCH 3, OC 2 H 5, etc., which can be hydrolyzed into easily crosslinked silanol groups, dehydrated and condensed with hydroxyl groups on the surface of the fabric. Covalent bonds attach and fix it on the surface of the fabric. Through the graft polymerization of organosilicon, a strong membrane that can kill and inhibit bacteria is formed. The film is non-toxic, non-irritating, harmless to the human body, safe and reliable. R1 is a hydrocarbyl group, an oxygen-containing or nitrogen-containing group, such as (CH2)3NHCH2CH2, CH2COCH2CH2, CH2, etc.; R2 is a hydrocarbyl group containing 1-20 carbon atoms; X is an acid radical anion.
