Environmentally friendly textile auxiliaries developed in China

There are many varieties of environmentally friendly Textile Auxiliaries developed in China. It involves various processing steps of textile printing and dyeing. Among them, environmentally friendly pretreatment new additives include scouring agent zS-95, scouring agent KC301+, chelating agent s, hydrogen peroxide stabilizer GJ-201, etc. For example, scouring agent zS-95 is a kind of cotton. High-performance low-foaming scouring agent for fabrics, fully biodegradable within 48h, alkali resistant to 150g/L, treated fabric with excellent water absorption and good wettability and cleansing properties The whiteness is also free of phosphorus and alkylphenol. It can be used in alkali-oxygen bleaching-bath cold bleaching process and steaming process, especially suitable for short-flow pretreatment; for example, hydrogen peroxide stabilizer GJ-201 is composed of copolymer of saccharide compound and carboxylic acid compound, which is excellent. It has the characteristics of affinity and biodegradability, good alkali resistance, large activation energy and no decomposition within 100 °C, and its performance is similar to that of alkyl glycosides. In the environmental protection printing and dyeing new additives, there are formaldehyde-free fixing agent DUR, formaldehyde-free fixing agent ZS-201, paint printing adhesive CS, low-temperature crosslinking agent LE-780, thickener CTF and so on. For example, formaldehyde-free fixing agent DuR is a polyquaternary ammonium linear compound, which can improve the fixing and soaping fastness of reactive dyes and direct dyes, and has no color change. Another example is low-temperature cross-linking agent LE-780. It is an imine-based formaldehyde-free cross-linking agent with good color fastness and can be used in the temperature range of 100-200 °C. Since it is suitable for low temperature crosslinking, it also has no effect on the hand and fastness of the fabric.

In the environment-friendly finishing of new additives, there is no formaldehyde-free finishing agent PC, durable pressing finishing agent DGZ-28, RS series silicone softener, waterproof finishing agent H (dissolution medium HA), antibacterial and deodorant finishing agent HM98 , Chitosan antibacterial deodorant and moisturizing agent; for example, formaldehyde-free finishing agent PC is a carboxylic acid type non-iron finishing agent, after which the fabric has high washing water flatness, good wrinkle recovery performance and high strength retention rate. And no yellowing tendency, etc., the finishing effect is similar to that of butane tetracarboxylic acid; and the antibacterial and deodorant finishing agent HM98 is synthesized, refined and compounded by triethoxy octadecylsilane quaternary ammonium salt and broad-spectrum bactericidal drugs. It is safe, non-toxic, non-irritating, and has a bacteriostatic rate of over 98%. After 50 times washing, the bacteriostatic rate is still over 90%.
