Natural pure cotton crease-resistant finishing agent

Abstract

The invention discloses a natural pure cotton crease-resistant finishing agent. The finishing agent comprises the following ingredients, by weight, 2-4 parts of soybean powder, 3-7 parts of peanut leaf extract product, 2-5 parts of buckwheat extract product and 0.7-1.2 parts of corn stigma extract product. The crease-resistant finishing agent meets environment protection and green ecology requirements, contains no formaldehyde, is beneficial for health and environmentally friendly, and is cheap in price. Through enhancement of lateral acting force among fiber molecules, the pure cotton fabric has good crease-resistant and shrinkproof performances, has washing fastness, a strong retention value and good hand feeling, and has good market popularization values and economic benefits.

Description

Technical field: [0001] The invention belongs to the application field of textile auxiliaries, and relates to a natural pure cotton anti-wrinkle finishing agent. Background technique: [0002] Anti-wrinkle finishing agents can give textiles, especially cellulose fiber fabrics, a smooth and crisp appearance, and can also make them washable and wearable or durable for pressing. [0003] At present, the main anti-wrinkle finishing agent on the market is N-methylolamide anti-wrinkle finishing agent, which is currently the most used anti-wrinkle finishing agent, but it has the problem of releasing formaldehyde; polycarboxylic acid anti-wrinkle finishing agent It can improve the wrinkle resistance and dimensional stability of cotton, viscose and linen fabrics, such as citric acid wrinkle-resistant finishing agent, but a key problem hindering the development of fabric citric acid wrinkle-resistant finishing is the yellowing of the finished fabric, which causes the fabric whiteness ...

Problems solved by technology

[0003] At present, the main anti-wrinkle finishing agent on the market is N-methylolamide anti-wrinkle finishing agent, which is currently the most used anti-wrinkle finishing agent, but it has the problem of releasing formaldehyde; polycarboxylic acid anti-wrinkle finishing agent It can improve the wrinkle resistance and dimensional stability of cotton, viscose and linen fabrics, such as citric acid wrinkle-resistant finishing agent, but a key problem hindering the development of fabric citric acid wrinkle-resistant finishing is the yellowing of the finished fabric, which causes the fabric whiteness to be obvious decrease, especially when the baking temperature is increased; glyoxal anti-wrinkle finishing agents can undergo cross-linking reactions with cotton fibers under acidic conditions, but the reactivity is low and high-efficiency catalysts are required, and the strength of the finished fabrics The loss is serious, and the processing cost is also high; the polyurethane finishing agent does not contain formaldehyde after washing, and has good film-forming properties and elasticity, but its high temperature resistance is poor, and it is prone to yellowing, especially the aromatic polyurethane. Seriously; the anti-wrinkle finishing agent of polyol condensate has good resilience of the fabric after finishing, and can give the fabric the desired soft and smooth elastic feel, without the problem of chlorine loss, and the use method is still padding method, which is simple Convenience, although its formaldehyde conversion rate is high and free formaldehyde content is low, the presence of formaldehyde still has adverse effects on the human body and the environment; chitosan anti-wrinkle finishing agent is a natural anti-wrinkle finishing agent, and its main components can not only be used as Dyeing accelerator can also be used for anti-wrinkle finishing of fabrics, and has good washing resistance, has no effect on fabric strength, the most important thing is that there is no formaldehyde release problem, and chlorine resistance is good, but its processing and preparation costs are high, which improves the process. processing cost
