What is antibacterial finishing?

The existing antibacterial finishing has a wide range, and its basic mode of action includes: acting with cell membranes, acting in the process of metabolism or acting in the core material. Oxidants such as acetaldehyde, halogens, and peroxides first attack the cell membranes of microorganisms or penetrate the cytoplasm to act on their enzymes. Fatty alcohol acts as a coagulant to irreversibly denature the protein structure in microorganisms. Chitin is a cheap and easy-to-obtain antibacterial agent. The protonated amino groups in the gum can bind to the surface of negatively charged bacterial cells and inhibit bacteria. Other compounds, such as halides and isotriazine peroxides, are highly reactive as free radicals because they contain one free electron.

Quaternary ammonium compounds, biguanamines, and glucosamine exhibit special polycationicity, porosity and absorption properties. When applied to textile fibers, these antibacterial chemicals bind to the cell membrane of microorganisms, breaking the structure of the oleophobic polysaccharide, and ultimately leading to puncture of the cell membrane and cell rupture. The silver compound is used because its complexation can prevent the metabolism of microorganisms. However, silver is more effective against negative bacteria than positive bacteria, but less effective against fungi.
