Abstract

The invention relates to the technical field of textile finishing agents, in particular to a formaldehyde-free durable crease-proof finishing agent which is prepared by adopting the following raw material proportions: 20.0%-40.0% of acetal crosslinking agent, 28.0%-50.0% of polymeric carboxylic acid, 5.0%-10.0% of polysiloxane, 8.0%-15.0% of catalyst and 8.0%-16.0% of deionized water; the finishing agent is characterized in that an crease recovery angle of the cellulosic fiber fabric treated by the finishing agent can reach above 299 degrees, and maintain above 287 degrees after the cellulosicfiber fabric is washed for 5 times; the whiteness of the fabric after being finished is above 78.2%, and the tear strength retention rate is 68%-75%; and the composition is applicable to cotton fiber, bast fiber, bamboo pulp fiber (Lyocell), viscose fiber, Modal fiber and tencel fiber.

Description

Technical field: [0001] The invention relates to the technical field of textile finishing agents, in particular to a formaldehyde-free durable non-ironing finishing agent and its preparation method and application. Background technique: [0002] Cellulose fiber fabrics have the advantages of soft touch, soft luster, good warmth retention, wear resistance, strong sweat absorption, and comfortable wearing. Ironing and other shortcomings, in order to improve its performance and commercial value, usually by adding non-ironing finishing agent for finishing processing. The non-ironing finishing agents used mainly include urea-formaldehyde, melamine-formaldehyde, dimethylol dihydroxyethylene urea, dimethylol carbamate, N-methylol amide resin initial shrinkage and etherification etc. The finished fabric has high dry and wet wrinkle resistance, and the seams and stitches formed during the pressing of the garment remain unchanged after washing, achieving an effect equivalent to that ...
