Abstract

The invention relates to a finishing method of an antibacterial cotton fabric. The finishing method comprises the following steps: performing light-shielded oxidation reaction on cotton fibers put into a sodium periodate solution with certain concentration to obtain oxidized cotton fibers; dipping the oxidized cotton fibers into a chitosan solution with certain concentration for reacting to obtain chitosan grafted cotton fibers; and finally, dipping the chitosan grafted cotton fibers into a silver nitrate solution with certain concentration for a certain period of time, dipping twice and rolling twice, and heating the fibers in a 600W microwave oven for 8 minutes to obtain the antibacterial cotton fabric. According to the invention, the cotton fabric is taken as a base material, and the nano-silver antibacterial cotton fabric is generated by chitosan in situ through a microwave radiation method and is excellent in antibacterial and washable performance.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a method for finishing antibacterial cotton fabrics. Background technique [0002] Although natural cotton products have the advantages of wearing comfort, reproducibility and biodegradability, but in the process of wearing, due to the large specific surface area and strong moisture absorption capacity of cotton fibers, cotton products are very easy to attach microorganisms and Create conditions for its reproduction and propagation, resulting in damage to fiber strength, stains and discoloration, unpleasant odors, and even the spread of diseases, affecting human health. Therefore, in the research of cotton fiber modification, an important research direction is to realize the antibacterial properties of cotton fiber and reduce the invasion of bacteria on the human body. Nano-silver is often used as an antibacterial finishing agent due to its safe, non-toxic and efficient antibacterial pro...
