Problems solved by technology

Flame retardant finishing agents for cotton fabrics are high value-added products, but most of the durable flame retardants for cotton are made of methylol groups generated from formaldehyde as reactive groups to cross-link with cellulose fibers, and there is a problem of free formaldehyde release in finishing fabrics ; And the flame retardant without methylol has poor washability, so the development of washable, aldehyde-free and efficient durable flame retardants for cotton has become a research difficulty and hot spot

Abstract

The invention discloses a cotton fabric flame-resistant finishing liquid. The finishing liquid is prepared from 2-30 parts of high-polymeric ammonium phosphate, 1-8 parts of octadecanamide / imvite aqueous dispersion, 4-20 parts of resin cross-linking agent, 0.5-3 parts of organic phosphate and 50-90 parts of water. The high-polymeric ammonium phosphate can be disintegrated at the high temperature to generate polyphosphoric acid to accelerate dehydration of fibers, and meanwhile, the initial decomposition temperature of the fabric is reduced, wherein a lower initial decomposition temperature is beneficial to generation of char residues and reduction of generation of combustible gas products; the octadecanamide and imvite nanometer material can remarkably improve the char forming efficiency, reduce the combustible gas products and enable the fabric to have better flame-resistant properties. The invention further discloses a finishing method of the cotton fabric flame-resistant finishing liquid.

Description

technical field [0001] The invention relates to the technical field of finishing liquid compositions, in particular to a flame-retardant finishing liquid for cotton fabrics and a finishing method thereof. Background technique [0002] Cotton fabric is the fabric with the highest usage rate so far, with excellent hygroscopicity, moisture retention, heat resistance, alkali resistance and hygiene. The main reason is: cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb water into the surrounding atmosphere, and its moisture content is 8-10%. Therefore, it touches human skin and makes people feel soft and soft. Not stiff. In addition, cotton fiber is a poor conductor of heat and electricity, and its thermal conductivity is extremely low. When it is below 110°C, it will only cause the moisture on the fabric to evaporate without damaging the fiber. However, among many natural fibers, cotton has the lowest limiting oxygen index, only 18, which is...
