Abstract

The invention discloses a scouring method of a real silk fabric. The scouring method comprises the following steps: (1) pre-treating raw silks in an acid liquid at the temperature of 50-60 DEG C to swell the silks; (2) performing primary scouring with a scouring agent, namely a composite of an alkali scouring agent and a surfactant scouring agent; (3) performing secondary scouring, wherein a bleaching agent is added into a secondary scouring agent; and (4) after-treating, namely treating the scoured real silks from step (3) in water at 45-55 DEG C after swelling. The scouring method is simple, enhances the scouring effect of the scouring agents, and effectively solves the problem of unclean effluent of the alkali scouring agent; meanwhile, the scoured silks have the characteristics of high strength, good capillary effect, soft handfeel, excellent whiteness and low cost, and the product quality is ensured.

Description

technical field [0001] The invention relates to a method for refining silk fabrics, belonging to the technical field of textile engineering. Background technique [0002] Refining is an important process in the production and processing of silk fabrics. The success of refining is closely related to the quality of silk fabrics. In addition to dissolving most of the sericin wrapped around the silk fibers during the refining process and keeping the silk fibers from being lost as much as possible, the capillary effect of the silk fibers should also be improved to increase the affinity for dyeing materials, which will be used later. Create a good foundation for dyeing and finishing processing. The current refining method adopts the soap-alkali method, that is, the pretreated silk fabric is obtained after the initial scouring, secondary scouring, second heat soaking, washing and dehydration processes. The physical indexes of the above-mentioned soap-alkaline refining are basical...
