Chemical fiber auxiliary agent for improving chroma of chemical fibers

Abstract

The invention discloses a chemical fiber auxiliary agent for improving the chroma of chemical fibers. A non-foam detergent agent NP-2 is used so that a chemical fiber textile has good anti-staining performance and the problem that a chemical fiber product is easily stained by other colors in a polyester recycling technology is solved; the pure color of the chemical fiber product is ensured and thechroma of the chemical fiber product is improved; an efficient oil-removing agent is added, so that oil in polyester wastes can be effectively removed; tartaric acid is used as an anti-oxidization synergist, a set retarder, a tanning agent and a chelating agent to effectively ensure that the color on the surface of the chemical fiber product is pure and not lost; an oxygen bleaching stabilizer isa compound of organic carboxylic acid and a special auxiliary agent and has the advantages of high temperature resistance, strong alkali resistance, oxidization resistance and no toxicity; the stabilization effect of the oxygen bleaching stabilizer on hydrogen peroxide exceeds that of sodium silicate, and silicon scales which are difficult to remove are not generated; after the textile is subjected to oxygen bleaching, the whiteness is high and the hand feeling is soft; the chemical fiber auxiliary agent for improving the chroma of the chemical fibers has relatively strong alkali resistance,permeability and a certain emulsifying capability and is applicable to a pre-treatment technology of the polyester wastes and the high-quality chemical fiber products with high chroma are obtained.

Description

technical field [0001] The invention relates to the technical field of chemical fiber additives, in particular to a chemical fiber additive for improving the chroma of chemical fibers. Background technique [0002] Chemical fiber is a fiber with textile properties made from natural polymer compounds or artificially synthesized polymer compounds through the preparation of spinning dope, spinning and post-treatment processes. The length, thickness, whiteness and gloss of the fibers Such properties can be adjusted in the production process, and have the advantages of light resistance, wear resistance, easy washing and drying, no mildew, no insects, etc., widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, etc. , fishing nets, electrical insulation wires, medical sutures, tire cord fabrics and parachutes, etc. Generally, polymer compounds can be made into solutions or melts, pressed out from the pores of the spinneret, and then solidi...

Problems solved by technology

[0003] The object of the present invention is to provide a kind of chemical fiber auxiliary agent that improves the chromaticity of chemical fiber, by adopting non-foaming soap oil NP-2 to make chemical fiber fabric have good anti-staining performance, solve the problem of chemical fiber products in the polyester recycling process of manufacturers. Contamination of other colors ensures the pure color of chemical fiber products and improves the chroma of chemical fiber products. The addition of high-efficiency degreasing agents can effectively remove grease in polyester waste. Tartaric acid is used as an antioxidant synergist, retarder, Tanning agents and chelating agents have low solubility in water at low temperatures and form insoluble calcium salts, which can effectively protect the pure color of the surface of chemical fiber products without loss. Oxygen bleaching stabilizers can be dissolved in cold water and hot water. Organic carboxylic acids and special auxiliary Agent complex, high temperature resistance, strong alkali resistance, anti-oxidation, non-toxic new non-silicone bleaching stabilizer, the stabilization effect on hydrogen peroxide exceeds sodium silicate, and will not produce "silicon scale" that is difficult to remove, fabric oxygen bleaching With high whiteness and soft hand feeling, the chemical fiber additives for improving the chroma of chemical fibers have strong alkali resistance, permeability and certain emulsification ability, and are suitable for the pretreatment process of polyester waste, so that high-quality products with high chroma can be obtained. Chemical fiber products to solve the problems raised in the above-mentioned background technology
