Problems solved by technology

[0002] With the acceleration of people's life rhythm, more and more clothes with non-ironing effect are favored by all kinds of people. Non-ironing clothes can save a lot of time, but At present, the non-ironing clothes produced on the market, no matter the non-ironing fabric or the non-ironing process of garments, the resin crosslinking agent used in the production process mostly uses formaldehyde as the initial raw material. These finishing agents are synthesized from other amides. Although these finishing agents are modified and etherified in the later use to reduce the content of free formaldehyde, due to the reversibility of the modification and etherification reactions, they cannot be completely modified and etherified. Therefore, when they are used for non-ironing finishing of cotton fabrics and subsequent fabric storage, production, sale, and consumer use and wearing, formaldehyde gas will be continuously released, which is not conducive to people's health

Abstract

A durable press finishing agent comprises components in parts by mass as follows: 15-25 parts of polyurethane resin, 25-35 parts of polyhydric alcohol, 3-8 parts of a metal-salt catalyst, 1-5 parts of poly-methylsiloxane silicone bodies and 20-35 parts of water, wherein the metal-salt catalyst adopts basic aluminum chloride or aluminum chloride hexahydrate; and polyhydric alcohol adopts ethylene glycol or diethylene glycol. The provided durable press finishing agent doesn't take formaldehyde as a resin cross-linking agent for synthesizing raw materials, no formaldehyde is left over when the durable press finishing agent is used for processing clothes, and the use is safe.

Description

technical field [0001] The invention belongs to the technical field of textile processing, and in particular relates to a non-ironing finishing agent. Background technique [0002] With the acceleration of people's life rhythm, more and more clothes with non-ironing effect are favored by all kinds of people. Non-ironing clothes can save a lot of time. Ironing is still a non-ironing process for garments. Most of the resin crosslinking agents used in the production process are synthesized from formaldehyde as the initial raw material with urea, cyclic urea, carbamate or other amides. Modification and etherification treatment to reduce the content of free formaldehyde, but due to the reversibility of the modification and etherification reaction, completely modified and etherified products cannot be obtained, so they are used for non-ironing finishing of cotton fabrics and subsequent Formaldehyde gas will continue to be released during storage, production, sale, and consumer u...
