Method for producing silk quilt by utilizing sericin

Abstract

The invention relates to a process for producing a silk quilt by utilizing sericin, which comprises the following steps of: sequentially carrying out vacuum penetration and cocoon cooking on raw material cocoons; then carrying out one-particle hemming to form a yarn sheet; carrying out sericin fixation processing on the yarn sheet to enable the sericin to be fixed; and after carrying out post-treatment, drawing to form a silk quilt inner tube. The process is characterized in that in both the vacuum penetration and cocoon cooking processes, a raw silk softener is added; the yarn sheet is timely dried by infrared light or hot air after one-particle hemming is carried out to form the yarn sheet; before the sericin is fixed, the yarn sheet has sericin content of 15 percent to 26 percent; and the sericin is fixed by a cross-linking agent. According to the invention, the sericin can be reserved to the greatest degree; and denatured proteins of the silk quilt can be reduced, and silk fibers containing the sericin not only are soft, but also have stable performance.

Description

technical field [0001] The invention relates to a method for making a silk quilt, in particular to a method for producing a silk quilt using sericin. Background technique [0002] Silk is composed of sericin and silk fibroin. Silk fibroin is the main part of silk. Sericin is on the periphery of silk fibroin and has a certain protective effect on silk fibroin. Sericin is composed of 18 kinds of amino acids needed by the human body such as glycine and serine. It is very similar to human keratin and collagen. It has good compatibility with human skin and is a high-quality polymer material. However, due to the active properties of sericin, during the use of silk quilts, the water, salts and acidic components evaporated from the human body are gradually absorbed in the silk quilts, and the remaining sericin in the silk quilts gradually denatures, resulting in the hardening and yellowing of the silk quilts. , affecting the bulkiness and warmth retention of silk quilts. In additi...

Problems solved by technology

The above method only proposes a method for arranging silkworm cocoons into ordered silk sheets, without analyzing and studying the softness of cocoon silk and the performance stability of sericin, etc., so the silk quilt made has the problem of hard strands. Moreover, after long-term use, the sericin in the silk is easy to absorb water and stick to cause problems such as the hardening of the silk quilt, which affects the quality of the silk quilt to a certain extent.
