Problems solved by technology

However, the existing technology research also shows that the enzymatic cross-linking modification of wool fiber itself by MTG can only improve a few properties such as strength, anti-felting, and anti-wrinkle, and cannot endow wool with more functions.

Abstract

The invention provides a biological enzyme and adsorption coupled method to improve the flame retardancy of wool, and in particular provides a function finishing method for wool by using fire retardant complexing agent. The fire retardant complexing agent includes a transfer TGase (MTG), a fire retardant, a penetrating agent, a softener, industrial phosphoric acid, formic acid, citric acid, a buffer, and the balance of water. The prepared fire-retardant yarn can effectively prevent yarn from combustion.

Description

Technical field: [0001] The invention relates to a flame retardant and a flame retardant process for carpet yarn, belonging to the field of flame retardant and flame retardant process manufacturing, in particular to a flame retardant for wool carpet yarn and its processing technology. Background technique: [0002] Most of the textile fiber products currently produced and used (yarns, fabrics, clothing, decorative items, etc.) do not have flame retardant function and are flammable items, and these textile fiber products are widely used in homes, hotels, institutions, Schools, transportation vehicles (aircraft, trains, automobiles, etc.) public places and other fields, which put forward special quality requirements for the function (flame retardancy) of textile fiber products. [0003] Wool yarn is often used as the main raw material in carpet products, especially high-grade carpets. Wool belongs to the fibrous protein of keratin, contains more cysteine, cystine, methionine,...
