Abstract

The invention involves a organic and inorganic composite self-cleaning finishing agent and its application method on fiber products, the organic and inorganic composite self-cleaning finishing agent includes 40% component A and 60%B component (weight percentage), its application method on fiber products includes: (1) freshly preparing component A and B organic and inorganic composite self-cleaning finishing agent, (2) slop padding work solution and fiber products, drying and curing, (3) characterizing the self-cleaning property of textiles through the water repellency, oil repellency and soil release property. The organic and inorganic composite self-cleaning finishing agent in the invention has good stability and repeatability, it has good water repellency, oil repellency and soil release property when it is applied in fiber products, it can meet the needs of developing various fiber high-grade self-cleaning rib fabrics.

Description

technical field [0001] The invention belongs to a self-cleaning finishing agent for fiber products, in particular to an organic-inorganic composite self-cleaning finishing agent and its application. Background technique [0002] Dirt on fabrics includes water-soluble dirt, oily dirt, and dust. Water-soluble dirt and oily dirt are caused by the contact between clothing and human body, or contamination caused by foreign oil (food oil or machine oil, etc.); dust is mainly generated by electrostatic action. Antifouling and easy decontamination are two different concepts, and there is an intrinsic connection between the two. Textiles will be stained gradually during use. Antifouling means that clothing textiles will not be stained by water-based dirt and oily dirt during use, and will not absorb dry dust or particles on fibers or fibers due to static electricity. fabric surface. Finishes that impart stain-repellent properties to textiles are known as stain-repellent finishes. ...
