Abstract

The invention discloses an environment-friendly scouring agent which comprises the following components: sorbitan fatty acid ester polyoxyethylene ether, alkyl polyoxyethylene ether sulfate, natural fatty alcohol polyoxyethylene ether, alkylethoxyglucoside, alcohol ether carboxylate, a chelating dispersant, an activating agent, an organic silicon defoamer and water, wherein the saponification value of sorbitan fatty acid ester polyoxyethylene ether is 80-120, and the proportion of sorbitan fatty acid ester polyoxyethylene ether of which the saponification value is 85-110 is 80 mol or above, the scouring agent has high concentration alkali resistance, so that the process time can be reduced, and the production efficiency is improved; the raw materials and by-products are environment-friendly, and do not cause water body nutrification problem; processed fabric can obtain the satisfying capillary effect and whiteness so as to meet follow-up process requirements of dyeing, printing and the like.

Description

technical field [0001] The invention relates to the field of pretreatment auxiliary agents for textile printing and dyeing. More specifically, the present invention relates to an environmentally friendly scouring agent. Background technique [0002] Scouring agent mainly refers to all kinds of anionic, nonionic surfactants and appropriate additives, which are obtained through a certain proportioning method, which mainly has a cleaning effect and has synergistic effects such as penetration, emulsification, dispersion, and complexation. compound. The scouring agent plays a very important role in the process of retreating, boiling and bleaching. At present, some raw materials of domestically produced scouring agents, such as alkylphenol polyoxyethylene ether, sodium dodecylbenzenesulfonate, sodium tripolyphosphate, ethylenediaminetetraacetic acid, etc., will produce chemical substances harmful to human body and ecological environment It has been listed as a non-environmental...
