Abstract

The invention discloses a method for scouring and bleaching a silk fabric. The method comprises the following steps: performing pretreatment, namely soaking the silk fabric in a first scouring tank, wherein 1-2g / L of sodium carbonate and 0.2-0.5g / L of penetrating agent JFC are contained in the first scouring tank; scouring, namely putting the silk fabric in a second scouring tank, wherein 8-15g / L of silk scouring agent, 1-3g / L of synthetic detergent, 1-3g / L of liquid sodium silicate and 0.2-0.5g / L of liquid sodium hydroxide are contained in the second scouring tank; washing, namely putting the scoured silk fabric into a third scouring tank for washing; performing enzyme scouring, namely putting the washed silk fabric into a fourth scouring tank, wherein 0.4-1g / L of alkaline protease, 0.5-1g / L of ethylene diamine tetraacetic acid and 1-3g / L of sodium carbonate are contained in the fourth scouring tank; bleaching, namely putting the silk fabric subjected to enzyme scouring into a fifth scouring tank, wherein 6-10g / L of peroxysulphate and 2-4g / L of sodium pyrophosphate are contained in the fifth scouring tank; and repeatedly washing, airing or drying, and finishing scouring and bleaching of the silk fabric.

Description

technical field [0001] The invention relates to a method for producing real silk fabrics, in particular to a method for hanging and bleaching real silk fabrics. Background technique [0002] In addition to the main fibroin of the fiber, real silk also contains natural impurities such as sericin, wax, pigments, inorganic substances and carbohydrates, as well as artificial impurities such as impregnation aids added for weaving. The existence of these impurities not only damages the good qualities of silk such as softness, brightness and whiteness, but also affects the subsequent dyeing and finishing of real silk fabrics. Therefore, silk fabrics need to be scoured and bleached. The commonly used techniques for hanging silk are soap-alkali method, special silk scouring agent method, enzyme-synthetic detergent method and synthetic detergent-alkali method. Soap-alkaline scouring is prone to defects such as white mist, soap stains, and unclear water. The special scouring agent me...
