Problems solved by technology

[0003] In research at home and abroad, most of the fabric style finishing agents are organosilicon polymers. Because of the large Si-O-Si bond angle on the main chain of the organosilicon, the Si-O bond is long and the bond energy is high, the intermolecular interaction Small force, excellent low-temperature smoothness, fabrics treated with silicone have a unique soft, smooth, plump style, such as the Chinese patent application number 201510740051.2 "a block polyether elastic silicone softener and Its preparation method and application", the block polyether elastic silicone prepared by the epoxy addition reaction of amino polyether and epoxy-terminated silicone oil can endow the fabric with a soft and fluffy comprehensive hand feeling, but it has poor hydrophilicity, Easy yellowing at high temperature, great damage to fabric strength, reduced fabric wet rubbing fastness and pilling resistance; therefore, some scholars modify silicone and introduce polyurethane structure to obtain polyurethane modified silicone style finishing agent, such as the application number 200810053726.6 of the Chinese patent "anionic polyurethane and amino silicone oil composite water dispersion and its preparation and application", using polyether polyol, anionic diol chain extender and diisocyanate reaction to prepare anionic polyurethane, and then The anionic water-dispersed microemulsion prepared by blending with amino silicone oil endows the fabric with elasticity and softness, and the wet rubbing fastness, anti-pilling and hydrophilicity of the fabric treated with it are better than those of fabrics treated with silicone softeners. However, high temperature yellowing and strong damage cannot be solved, which greatly limits its application and development

Abstract

The invention relates to a textile style finishing agent composition and a preparation method thereof. The textile style finishing agent composition is an aqueous dispersion containing polyurethane formed by using long-chain fatty amide and poly(ethylene glycol)(methyl) acrylate to hybridly block polyurethane prepolymer. Textiles finished by the textile style finishing agent composition prepared by the invention have excellent handle, elasticity and drapability, and cannot become yellow under high temperature, hydrophilicity and strength are remarkably increased in comparison with the hydrophilicity and strength of raw cloth, and moreover, the rubbing fastness and anti-fuzzing and -piling property of textiles are not affected.

Description

technical field [0001] The invention relates to a fabric finishing agent composition and a preparation method thereof, in particular to a fabric style finishing agent composition and a preparation method thereof. Background technique [0002] T / R fabric, that is, polyester / viscose blended fabric, is widely accepted by people because of its high elasticity, crispness, resilience and good hygroscopicity and softness of viscose. With the increasing demand for clothing fabrics, A single style is far from enough, and the diversification of fabric styles presents an increasingly obvious market demand. Style finishing agents are a very important way to endow fabrics with stylized processing and finishing. Therefore, the development and application of style finishing agents, has become increasingly important. [0003] In research at home and abroad, most of the fabric style finishing agents are organosilicon polymers. Because of the large Si-O-Si bond angle on the main chain of the...
