Problems solved by technology

The process is complicated and inefficient. The reported strength of regenerated silk fibers is generally much lower than that of natural silk fibers. From these experiments and reports, it can be seen that there is still a long way to go for commercial breakthroughs in regenerated silk fibers. technology gap

preparation example Construction

[0034] The preparation process steps of the present invention are as follows: 1) Coating treatment: the silk thread obtained by pulling and twisting is passed through a polyethylene glycol bath for coating treatment, after coating treatment, it is wound on the feeding roller, the temperature of the polyethylene glycol bath controlled at room temperature to 80 0 Between C; 2) Stretching heat setting treatment: the silk thread wound on the feeding roller is stretched and wound on the heating roller for heat setting treatment; the stretching ratio is controlled by controlling the linear speed of the feeding roller and the heating roller, The stretch ratio is controlled between 1.05 and 1.3; the temperature of the feeding roller is controlled at room temperature to 110 0 C; the temperature of the heating roller is controlled at 150 0 C ~230 0 C; the silk thread is wound on the heating roller for 0.5 to 5 seconds; 3) cooling and collection, the silk thread after being heat-set by...

Abstract

A technology method for obtaining high-strength silk fibers includes the following steps that step1, according to coating treatment, silk threads obtained through throwing are coated by penetrating through a PEG bath box, and the coating temperature ranges from indoor temperature to 800 DEG C; step2, according to drawing and heat setting treatment, drawing and heat setting treatment is performed on the coated silk threads, the drawing ratio is 1.05-1.3, the drawing temperature ranges from indoor temperature to 1100 DEG C, the heat setting temperature ranges from 1500 DEG C to 2300 DEG C, and the heat setting time ranges from 0.5 second to 5 seconds; step3, according to cooling and collecting, the silk threads after drawing and heat setting are cooled at indoor temperature and then collected. The silk threads wound around a raw material thread wheel penetrate through the PEG bath box, and then are sequentially wound around a feeding rolling wheel, a heating rolling wheel and a collecting thread wheel, drawn by the feeding rolling wheel and the heating rolling wheel and collected on the collecting thread wheel through cooling after heat setting is performed through the heating rolling wheel. The device is simple in structure and suitable for industrial and large-scale production, and the high-strength silk threads can be obtained.

Description

technical field [0001] The invention relates to the textile industry, in particular to a process method and preparation equipment for improving the strength of mulberry silk fibers. Background technique [0002] Silk is a valuable raw material in the high-end textile industry. The inherent properties of silk fibroin are also important research objects in biotechnology and biomedicine. The predecessors have done a lot of research especially on the spinning and structural characteristics of silk. A key property of silk fiber is its tensile strength. According to literature reports, the tensile strength of natural silk is about 370MPa. In the weaving process of modern silk fabrics, because the tensile strength of silk fibers is not very high, it is easy to break, resulting in low weaving efficiency. Researchers have tried different methods to increase the strength of silk fibers to meet the requirements of high-efficiency textile production and its application in the field ...
