Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a formaldehyde-free anti-wrinkle finishing agent and its finishing method, to provide a formaldehyde-free and phosphorus-free cotton fabric anti-wrinkle finishing agent and its finishing method, and to solve the problem of traditional unsaturated carboxylic acid finishing agents. Fabric yellowing, low strength, poor polymerization effect, etc., and can also reduce the harm of phosphorus-containing wastewater to the environment, which is conducive to environmental protection and industrial production. After anti-wrinkle and durable pressing finishing, the treated fabric has good anti-wrinkle resistance, shape memory and washing resistance

Abstract

The invention discloses a novel formaldehyde-free crease-resist finishing agent. The novel formaldehyde-free crease-resist finishing agent is prepared from acryloyl succinic acid monomers, iso-octyl acrylate, styrene, methyl methacrylate, high-density polyethylene wax emulsion, dimethyl silicone oil, a non-phosphorus catalyst, N-beta-aminoethyl-gamma-aminopropyl methyl dimethoxy silane, etherified dihydroxyl ethylene urea, chitosan, polyethylene glycol and itaconic acid. The invention provides a formaldehyde-free phosphorus-free crease-resist finishing agent for a cotton fabric and a finishing method of the finishing agent. The problems that a traditional unsaturated carboxylic acid finishing agent is prone to yellowing, low in power, poor in polymerization effect and the like are solved, damage of phosphorus-containing wastewater to the environment can further be reduced, environment protection and industrial production are facilitated, and after crease-resist and durable pressing finishing is conducted, a treated fabric has good crease resistance, shape memorizing property and washing fastness.

Description

technical field [0001] The invention relates to a textile finishing agent, in particular to a formaldehyde-free anti-wrinkle finishing agent and a finishing process thereof. Background technique [0002] Cotton fabrics have many excellent wearing properties, such as softness, comfort, breathability, good hygroscopicity, excellent wearing performance and cheap price, which make them favored by people. However, cotton fabrics are easy to wrinkle during wearing and washing, cannot maintain a flat appearance, and need to be ironed frequently, thus bringing many inconveniences to people's lives. In order to overcome the wrinkling defects of cotton garments during wearing, it is necessary to perform anti-wrinkle finishing on cotton fabrics. [0003] Most of the existing fabric finishing agents used in the textile industry contain very high concentrations of formaldehyde, especially the fabric anti-wrinkle and anti-wrinkle finishing agents are mostly textile auxiliaries based on f...
