Abstract

The invention relates to a spinning scouring agent. The spinning scouring agent can be used for solving the problem that permeability and wettability of a spinning and scouring agent with a phosphate ester and fatty alcohol polyether system are poor. According to the technical scheme, the spinning scouring agent comprises the following components in parts by weight: 100 parts of phosphate ester and 5-20 parts of fatty alcohol ether, wherein the fatty alcohol ether has the general molecular formula, R-O-[(PO)n / (EO)m]-(EO)t-H, wherein R is C8-18 alkyl, [(PO)n / (EO)m] is a copolymerization chain segment composed of PO and EO, the number n of PO units in the copolymerization chain segment is 2-5, the number m of EO units in the copolymerization chain segment is 2-8, and the number t of EO structural units at a molecular tail end of the general molecular formula is 2-5. The technical problem is solved, and the spinning scouring agent can be used in a printing and dyeing pre-treatment process of various textile fabrics of cotton, fur, fibre, natural silk, synthetic fibers and the like.

Description

technical field [0001] The present invention relates to a textile scouring agent, in particular to a textile scouring agent comprising phosphoric acid ester and polyether. Background technique [0002] The scouring process is a complex chemical and physical chemical process of textiles at a certain temperature with alkali and scouring agents, which includes penetration, cleaning, puffing, emulsification, saponification, dispersion, chelation and decolorization, among which penetration and purification Washing is a relatively important function. The first step in the scouring process is that under the action of surfactants, the scouring liquid penetrates into the fiber to make the fibers and impurities expand; the second step is the cleaning function, that is, after the fiber is fully wetted, its Impurities are removed by heat and chemical soaping, emulsification, extraction, dispersion, etc. The role of the scouring agent is to help the lye penetrate into the fiber, promote...
