Problems solved by technology

The disadvantages of the alkali scouring method are: the softness, whiteness, luster and hand feeling of silk fabrics are very poor; high concentration of lye or too long scouring processing time will easily damage the structure of silk fibers and reduce the strength of silk fibers. elongation; the advantage of open-width rapid refining is that it can quickly remove sericin without damaging silk fibers, but the composition of the compound scouring agent is complex, which is not conducive to the purification and recovery of sericin; high-temperature and high-pressure refining equipment has high requirements for equipment
[0003] The protease refining in the prior art is mainly aimed at silk fiber, and the refining effect on wool fiber is relatively poor. The specific performance is that the scale layer on the surface of wool fiber is too damaged, which is not conducive to ensuring the strength of wool fiber and the bursting force of fabric.

Abstract

The invention discloses a wool silk fabric cold pressing refining process. The wool silk fabric cold pressing refining process comprises the steps including padding protease solution cold pressing andrefining, which are implemented step by step by, firstly, immersing fabric inside protease solution so that protease can be fully attached to the surface of wool fabric, heating the wool fabric to open the scale layer of the wool fabric and cracking the scale layer through the protease during cold pressing. The wool silk fabric cold pressing refining process is low in damage to fabric obtained through one-bath refining and meanwhile have low damage to the scale layer of wool.

Description

technical field [0001] The invention relates to the technical field of wool refining, in particular to a cold pile refining process of wool and silk fabrics. Background technique [0002] Wool and silk belong to protein fibers. Wool is a slender solid cylinder in a curled shape. The fiber structure is divided into three layers, namely the scale layer, the cortex layer and the medulla layer. Silk is mainly composed of silk fibroin and sericin coated outside, and also contains a small amount of impurities. The refining methods of wool silk fabrics in the prior art include soap refining, protease refining, open width rapid refining and high temperature and high pressure refining. The disadvantages of the alkali scouring method are: the softness, whiteness, luster and hand feeling of silk fabrics are very poor; high concentration of lye or too long scouring processing time will easily damage the structure of silk fibers and reduce the strength of silk fibers. Elongation; the a...
