Problems solved by technology

At present, the scouring usually adopts the soap-alkali method. The treated fabric can meet the standard requirements, the fabric has good smoothness and bright luster, but it needs to consume a large amount of alkali agent, the cost is high, the whiteness is poor, and the scouring time is long. High temperature increases energy consumption

Abstract

The invention discloses a real silk fabric scouring process which includes the steps: preparation of scouring agents; peracid pretreatment; primary scouring; finishing scouring; post-treatment. The real silk fabric scouring process has the advantages that scouring effect is good, and fabric damage is low by the aid of the self-made scouring agents. Peracid pretreatment agents are added in the scouring process of real silk fabrics, scouring is effectively accelerated, scouring temperature is reduced, scouring is performed by the aid of the scouring agents and surface active agents, so that the scouring process is simple, scouring effect is improved, and scoured fabrics are high in strength, good in hand feeling and capillary effect, excellent in whiteness and low in cost.

Description

technical field [0001] The invention belongs to the technical field of textile processing, and in particular relates to a scouring method for real silk fabrics. Background technique [0002] Silk is composed of silk fiber and sericin. Silk has whiteness and soft luster, good dyeing performance, good elasticity and softness, good moisture absorption performance, and is known as the queen of fibers. Sericin is the wrapping A layer of protective colloid on the outside of silk fibroin has a dull color and a rough handle. Most of the waxes, pigments and inorganic substances in silk are contained in sericin, which will affect the color of silk and make it difficult to print and dye. So silk fabrics need to be refined. [0003] Scouring is an important process in the process of silk fabric processing. The purpose of scouring is to remove most of the sericin except silk fibroin. At present, the scouring usually adopts the soap-alkali method. The treated fabric can meet the standar...
