Abstract

The invention relates to a phosphorus-free textile scouring agent, and solves the problem that the conventional phosphorus-free textile scouring agent has poor permeability and wettability. The novel phosphorus-free textile scouring agent comprises components in parts by weight as follows: 5-20 parts of saponin, 5-20 parts of fatty alcohol ether and 100 parts of an anionic surfactant, wherein the fatty alcohol ether has the general formula shown as the following formula (I): R-O-[(PO)n/(EO)m]-(EO)t-H, wherein R is C8-C18 alkyl; [(PO)n/(EO)m] is a copolymerized chain segment formed by PO and EO, the number n of PO units in the copolymerized chain segment ranges from 2 to 5, and the number m of EO units in the copolymerized chain segment ranges from 2 to 8, and the number t of EO structural units at the tail end of the molecule in the general molecular formula ranges from 2 to 5. With adoption of the technical scheme, the technical problem is better solved, and the phosphorus-free textile scouring agent can be applied to dyeing pretreatment processes for various textile fabric such as cotton, wool, linen, silk, synthetic fiber and the like.

Description

technical field [0001] The invention relates to a non-phosphorous textile scouring agent, especially a non-phosphorous textile scouring agent comprising saponin. 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 the sapon...
