Embodiment 1
[0019] The formula of the scouring agent used for the scouring and processing of real silk is composed of the following parts by weight:
[0039] The structure of the used N,N'-bis-fatty acyl ethylenediamine sodium dipropionate is as follows:
[0040]
[0041] The structure of sodium alkyl polyoxyethylene ether carboxylate used is as follows:
[0042] C 14 H 29 O(CH 2 CH 2 O) 5 CH 2 COONa
[0043] The maleic acid / acrylic acid copolymer used is a conventional industrial product, and the molecular weight can be between 1000 and 2000.

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 finishing processing technology, in particular to a scouring agent for scouring and processing real silk, and 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 silky smooth feel and good quality of real silk, it is necessary to carry out scouring processing for the main purpose of degumming. The scouring process also includes removing pigments, ash, oil wax and other dirt on silk fibers, improving the feel and hair effect of silk. Generally, the scouring process is carried out under weak alkaline conditions, and the sericin is expanded, swelled, and hydrolyzed under alkaline conditions. , and finally removed. In addition to alkali agents, scouring agents need to be added in the scouring process to help smooth degumming, and to ensure that the pH value is stabilized within a certain range duri...
