Problems solved by technology

Regenerated protein fiber mainly includes casein fiber, silk protein fiber and soybean protein fiber, its output is very small, and there are three main processes in the regeneration process of regenerated silk. Residual and purified EG reuse processing flow, the production of regenerated silk has become a trend at present, but the traditional raw silk production method is complicated and difficult to operate, so we propose a regenerated silk processing method

Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] The invention provides a technical solution: a method for processing regenerated silk, the specific steps of which are:

[0018] (1) Collect and classify the waste cloth and place it in the treatment box for degumming pretreatment. After treatment, add low-concentration salt into the treatment box to dissolve it in an organic solvent, and then filter the treated material through a filter device. Remove unnecessary impurities;

[0019] (2) Pour the filtered material in...

Abstract

The invention discloses a method for processing a regenerated filament in the field of regeneration technologies. According to the method, waste cloth is collected and placed into a processing box ina classified manner; as waste gases are generated due to chemical reactions when the waste cloth is processed, suction pumps are arranged at the tops of the processing box, a mixer, a reaction kettleand a precision filter, and the suction pumps are equipped with large gas collection cylinders. The waste cloth is processed into granulates, so as to solve the problem that the waste cloth cannot beconveyed in the prior art, and realize the environmental protection concept of using waste clothing as a raw material indeed, which are impracticable in a physical regeneration process. Because material production is carried out in a closed production line, personal safety hazards are eliminated; because the material is produced by self, and foreign matter sorting is performed from waste cloth purchasing to material production, the quality of the material is ensured, mixing of metal impurities is avoided, and the production process of the material meets the requirement of environmental protection.

Description

technical field [0001] The invention relates to the technical field of recycled materials, in particular to a processing method for recycled silk. Background technique [0002] Regenerated silk is also called regenerated fiber. Regenerated fiber is a fiber made of materials containing natural cellulose polymers such as cotton linters, wood, reeds, etc. Regenerated fibers can also be made from raw materials containing protein. Regenerated cellulose fibers mainly include viscose fibers, cupro fibers and acetate fibers. Regenerated protein fiber mainly includes casein fiber, silk protein fiber and soybean protein fiber, its output is very small, and there are three main processes in the regeneration process of regenerated silk. Residual and purified EG recycling processing flow, the production of regenerated silk has become a trend at present, but the traditional raw silk production method is complicated and difficult to operate, so we propose a regenerated silk processing met...
