Abstract

The invention relates to a finish process technology for textile, especially a scouring agent for real silk scouring and processing. According to the quality percentage, the ingredients scouring agent is 5-20% double-surfactant N,N'-dialkylamide and carboxylate sodium, 5-20% surfactant alkyl polyoxyethylene ether carboxylate, 2-10% maleic acid / acrylic acid copolymer, 2-10% fibroin protective agent, 1-10% inorganic salts, and water for the rest. The scouring agent take the double-surfactant as the essential component, so the surface activity and the solubility of the scouring agent are improved greatly, and the moistening and the scrubbing effect are strengthened; taking the alkyl polyoxyethylene ether carboxylate surfactant as a complex surfactant, the scouring agent has good emulsification and lime soap dispersing capacity, so as to enhances the scouring effect. At the same time, because amide bond exists in the molecular structure, the scouring agent has good hard water-resistant capacity and lime soap dispersing capacity, and has the advantages of improving the smooth feeling of the scoured textile, and enhancing the capillary effect.

Description

technical field [0001] The invention relates to a textile post-finishing processing technology, in particular to a scouring agent for scouring processing of real silk, which belongs to the technical field of textile printing and dyeing processing. Background technique [0002] In the printing and dyeing process of real silk, in order to reflect the smooth feel and excellent quality of real silk, it is necessary to carry out refining processing with the main purpose of degumming. The scouring process also includes removing pigment, ash, oil wax and other dirt on the silk fiber, improving the feel and hair effect of silk. Generally, the scouring process is carried out under weak alkaline conditions, and sericin is expanded, swollen, and hydrolyzed under alkaline conditions. , and finally removed. In addition to alkali agents, scouring agents need to be added during the scouring process to help smooth degumming, and to ensure that the pH value is stabilized within a certain ra...
