Abstract

The invention discloses a treatment process for improving moisture absorption performance of silk fibers and relates to the technical field of silk treatment. The process comprises the following steps: (1) dissolving xylan in a solvent, preparing a xylan solution, and adding maleate to obtain a mixed solution; (2) adding triethylamine into the obtained mixed solution, reacting for 2 hours, precipitating the reaction product in ethanol, and filtering, washing and performing vacuum drying, grinding and milling to obtain a modifier; (3) dissolving the obtained modifier into an ethanol solution toobtain a modified solution; (4) adding the silk into the modified solution, introducing inert gases, vacuumizing, impregnating, and filtering the silk. According to the process disclosed by the invention, due to treatment of silk fibers, the moisture absorption performance of silk fibers can be obviously improved, and the dry breaking strength of the silk fibers can be improved to small extent.

Description

technical field [0001] The invention belongs to the technical field of silk treatment, and in particular relates to a treatment process for improving the hygroscopicity of silk fibers. Background technique [0002] Silk is a continuous long fiber formed by the cocooning of silk glands secreted by silk glands when cooked silkworms make cocoons. It is one of the earliest animal fibers used by humans. According to different foods, silk is divided into mulberry silk, tussah silk, celestial silk and castor silk. The thread drawn from a single silkworm cocoon is called cocoon silk, which is made of two single fibers bonded and covered by sericin. The cocoon filaments of several silkworm cocoons are drawn out, and the silk strips formed by bonding and wrapping with sericin are called raw silk. Several raw silks are processed into twisted yarns or braided sutures after processes such as winding, merging, twisting or weaving. As a high-grade textile raw material, silk products are...
