Flame-retardant fabrics are fabrics that have been treated with a flame-retardant process. The main function of flame-retardant fabrics is to prevent the spread of flames. Carbonization occurs in the area in contact with the flame. When the fire source is removed, the flame-retardant fabrics will no longer continue to burn.
Coated fabric is a kind of fabric treated with special technology. It can form a uniform layer of covering glue on the surface of the fabric to achieve waterproof, windproof and other functions. Coated fabrics are widely used in sportswear, down jackets, rainproof parkas, jackets, and windbreakers with advanced waterproof and moisture-permeable functions. It can also be used in national defense, navigation, fishing, offshore oil wells, transportation and other fields. The film-forming polymer is directly or indirectly applied to the surface of base fabrics such as woven fabrics, knitted fabrics or non-woven fabrics using devices such as scrapers, rollers or rotary screens, thereby changing the appearance, water permeability, air permeability, and windproofness of the base fabrics. , waterproof and other properties. A transparent coating containing a metal oxide or silicon oxide film, a nanosol of silicon oxide or other metal oxides, and prepared by acidic or alkaline hydrolysis of alkoxides can also be used. The produced nanosol generally contains 3%-20% metal oxide. After coating, a solvent-containing sol layer is formed on the surface of the textile. After drying and heat treatment, the coating solvent containing the xerogel layer is removed to form a porous oxidized structure. Nanosol modification through chemical and physical methods can change the functionality of the coating. Physical modification is to uniformly combine and fix the additives to the metal oxide substrate, so various additives that can increase the functionality of textiles can be used to improve light fastness, fiber stability to ultraviolet rays, and wear resistance. strength, antistatic and flame retardant properties. At present, plasma treatment technology is also used for fiber surface modification, such as changing the chemical properties of the fiber surface, improving fiber strength, and improving the durability of adhesives in finishing and coating.
