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.
