Problems solved by technology

Easing shrinkage can be slightly removed through relaxation treatment during fabric processing or continuous compression finishing in the final process, but it is not easy to prevent shrinkage caused by yarn bulking because it is the nature of cellulose fibers

Abstract

The invention discloses an anti-crease finishing process of cotton fabric after dyeing, belonging to the technical field of a fabric dyeing and finishing process. The anti-crease finishing process comprises the steps of drying dyed grey fabric, adding clean a specified amount of water into a reactor, then adding a finishing agent, stirring continuously, adjusting the PH value to be 5-6, reacting completely, then sizing and rolling liquid, crosslinking, baking, cleaning, softening, dewatering, coating a smooth softening agent, stentering and hot-sizing, checking and packaging, wherein, the finishing agent is prepared from the following components by weight percent: 70-80% of citric acid, 15-25% of maleic anhydride and 5-8% of nano TiO2, and meanwhile, 20-40% of the finishing agent is contained in clean water. The cotton fabric processed by the anti-crease finishing process disclosed by the invention has soft handfeeling, is smooth, and extremely good in air permeability and has a strong anti-contraction and anti-crease capability.

Description

technical field [0001] The invention discloses an anti-wrinkle finishing process for dyed cotton fabrics, belonging to the technical field of dyeing and finishing processes for textile fabrics. Background technique [0002] Because cellulose fiber has excellent water absorption, hygroscopicity, moderate strength and easy dyeing, it is the main material for underwear and shirts, especially natural fibers such as cotton and hemp. But fabrics made from these natural fibers inevitably crease and shrink when washed. At the same time, the regenerated cellulose fiber that appeared in the early 20th century, due to its low wet strength and the shrinkage and wrinkles during washing exceeded the allowable limit, made the creases and shrinkage during washing more serious. To solve this problem, anti-wrinkle finishing has appeared for cotton knitted fabrics. [0003] Anti-wrinkle finishing, also known as easy care, durable press finishing, wrinkle resistance, washability, non-ironing,...
