Abstract

The invention relates to a method for performing formaldehyde-free non-ironing treatment on a fabric by using ionic liquid as a catalyst for concerted catalysis. The method comprises the steps as follows: a finishing bath is prepared at the room temperature, and comprises 5-100g / L of a formaldehyde-free non-iron finishing agent, 0.05-1g / L of ionic liquid and 5-50 g / L of a catalyst; the fabric is respectively immersed and rolled for two times, the water retention is 50-100 percent, and the fabric is dried at 85-100 DEG C for 3-8 minutes, and is finally baked at 50-180 DEG C for 0.5-5 minutes. The method is simple to operate, and the realization of industrial production is facilitated. An obtained non-iron production has a fabric wrinkle recovery angle, which is improved over 10 DEG C compared with a common formaldehyde-free non-iron product, and the fabric strength of the non-iron product is equal to that of the fabric subjected to common formaldehyde-free non-iron finishing.

Description

technical field [0001] The invention belongs to the field of non-ironing finishing of fabrics, and in particular relates to a formaldehyde-free non-ironing method for fabrics through synergistic catalysis using ionic liquid as a catalyst. Background technique [0002] Cotton fiber has excellent wearability and is an ideal clothing and home textile fabric. However, cotton fiber has poor elasticity, and the fabric is easy to wrinkle after washing. In order to improve the washability and wearability of cotton fabrics, researchers have carried out the research on wrinkle-free finishing technology of cotton fabrics, and made great progress. At present, wrinkle-free finishing technology has become one of the important links in the dyeing and finishing process of cotton textiles. [0003] Traditional anti-wrinkle finishing agents are mainly N-methylolamide compounds, which will release a large amount of formaldehyde during fabric finishing, seriously affecting the health of operat...
