Abstract

An automatic stiff and smooth finishing method of a cotton fabric comprises the following steps: dipping a boiled and bleached cotton fabric in an aqueous N-methylmorpholine-N-oxide solution having a mass concentration of 15-25%, and cleaning to obtain a stiff and smooth cotton fabric. The stiff and smooth property of the finished cotton fabric is 2-3 times the original stiff and smooth property of the cotton fabric; and in the finishing process, N-methylmorpholine-N-oxide is removed through washing, and the cotton fabric contains no solvents. N-methylmorpholine-N-oxide is an environmentally-friendly new solvent, and can be recycled.

Description

technical field [0001] The invention relates to the technical field of textile engineering, in particular to a cotton fabric self-straightening finishing method. Background technique [0002] Cotton fabric has good hygroscopicity, air permeability, antistatic property, biocompatibility and wearing comfort, and is widely loved by consumers. However, cotton fabric is not crisp and has poor wrinkle elasticity. Therefore, cotton fabrics especially need to be stiffened and wrinkle-resistant. [0003] The current cotton fabric crisping treatment generally adopts polymer slurry for finishing, such as polyvinyl alcohol, starch, polyvinyl glycidyl ether, urea-formaldehyde resin, etc. After these treatment agents are treated, a layer of polymer film will generally be produced on the surface of the fabric. Therefore, when the crisp cotton fabric is used as underwear, these polymer films have a great chance of contacting human skin, and the biocompatibility and skin friendliness of c...
