A kind of degumming method of mulberry silk fabric

Abstract

The invention relates to a degumming method of mulberry silk fabric. The method comprises the following steps of: rolling: uniformly rolling to-be-boiled green silk; boiling-off liquid injection: putting the rolled green silk into a beam dyeing machine and uniformly injecting the prepared boiling-off liquid onto the rolled silk so that the rolled silk completely absorbs the boiling-off liquid; stacking: taking the rolled silk absorbing the boiling-off liquid out of the beam dyeing machine, wrapping the outer layer with a film, and stacking in a uniform rotation frame; washing: putting the stacked rolled silk into the beam dyeing machine, and washing; bleaching: bleaching the washed rolled silk; washing: washing the bleached rolled silk; and drying: unrolling and drying the washed clean rolled silk to obtain the fabric. According to the invention, the degumming of mulberry silk is performed by a method of boiling-off liquid injection and stacking; and compared with an existing degumming method, the degumming method provided by the invention has the advantages that the water consumption and energy consumption are remarkably reduced, and the problem of environmental pollution can be effectively solved.

Description

technical field [0001] The invention relates to the textile field, in particular to a degumming method for mulberry silk fabrics. Background technique [0002] Mulberry silk gray silk woven from raw silk contains more impurities, most of which are inherent sericin in the fiber material itself, in addition to silk-holding sizing applied during the weaving process and coloring dyes applied to identify the twist direction. These natural and foreign impurities exist on gray silk, which not only damages the unique soft feel and pleasing luster of silk fabrics, but also hinders the smooth progress of dyeing and finishing. Therefore mulberry silk fabrics must be degummed except for special varieties. The purpose of degumming is mainly to remove sericin, and at the same time, other impurities attached to the sericin are also separated from the fabric along with the removal of the sericin. [0003] At present, the commonly used equipment for degumming of mulberry silk fabrics is ma...

Problems solved by technology

During the degumming of the hanging training tank and the star frame refining equipment, the fabric is suspended and dipped in the solution in the form of circle code and S code for degumming. The time is long, the bath ratio is large, the water consumption is high, and the environmental pollution is serious.

During the degumming of the open-width scouring machine, the fabric is in the open-width state and under a certain tension. Although the time is short, the liquor ratio is still relatively large, the water and energy consumption is still high, and the environmental pollution is also serious.
