Polyester-fiber dyeing auxiliary agent

Abstract

A disclosed polyester-fiber dyeing auxiliary agent is composed of the following raw materials in parts by weight: 12-15 parts of guar gum, 7-10 parts of carboxymethylcellulose sodium, 1-3 parts of a surfactant, 1-3 parts of anhydrous sodium sulphate, 4-8 parts of a water softener, 0.5-1 part of branched isomerous alcohol ether, 2-4 parts of barium chloride, 3-5 parts of ammonium chloride, 0.1-0.5 part of goose feather protein, 0.1-0.3 parts of a cross-linking agent, 3-5 parts of a chelating agent, 5-10 parts of an emulsifier, 0.5-3 parts of a stabilizing agent, 8-10 parts of sodium silicate, 3-6 parts of magnesium sulfate, and 2-8 parts of fatty alcohol polyoxyethylene ether. The auxiliary agent helps to effectively improving the dyeing degree and the color fixing rate of polyester fiber, shorten dyeing time and improve the handfeel of polyester fiber textiles subjected to dyeing.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a polyester fiber dyeing auxiliary. Background technique [0002] Polyester fiber fabric is a synthetic fiber obtained by spinning polyester, which is formed by polycondensation of organic dibasic acid and dibasic alcohol. It has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation performance, and sunlight resistance. It is resistant to friction, mildew and moth, has a certain ability to resist dilute and strong acids, and has poor resistance to strong alkali, but the dyeing performance is poor. Generally, additives must be added to improve the colorability. The traditional method is to add a large amount of inorganic salts to promote dyeing. , but the biggest disadvantage of adding a large amount of inorganic salts to promote dyeing is that it will make the textile feel rough and may cause scratches on the dyed textile. At...
