Problems solved by technology

These two patents need to screen and process the functional particles used in the feeding process. Due to the large particle size, it is easy to affect the feeding growth of silkworms, resulting in a decrease in silk quality and yield
The results also show that more functional particles exist in sericin, and when silk is used, most of it needs to be degummed, so its modification effect is negligible
Moreover, both of them did not give the mechanical properties of the obtained silk, but only indicated that the obtained silk had some functions of the added particles, and the scope of application was narrow.

Abstract

The invention relates to a graphene oxide-feeding silkworm rearing method for preparing high-strength silk and a product of the silk. Specifically, graphene oxide is added into artificial feed for domestic silkworms and enters silk glands of the silkworms by utilizing absorption and conversion functions of the silkworms, and the silkworms spin cocoons to obtain the graphene oxide-containing high-strength silk. According to the method, the silk is modified on the premise of not damaging the natural quality of the silk to obtain the silk with more excellent mechanical properties.

Description

technical field [0001] The invention belongs to the field of silk fiber and its modification, and relates to a method for raising silkworms by adding food to graphene oxide for preparing high-strength silk and its products. Background technique [0002] The spinning solution composed of protein secreted by the silk gland when the silkworm cocoons, coagulates in the air to form a continuous long fiber called silk. As a biological fiber, silk not only has good gloss and comfortable touch, but also has strong mechanical properties and good biocompatibility, and is widely used in textile, medicine, cosmetics and biological fields. [0003] The breaking strength of degummed silk is about 400MPa, and the breaking elongation and breaking energy are about 15% and 30J / g respectively. In practical application, its performance still needs to be further improved, so it is necessary to modify silk. [0004] There are studies to enhance the performance of silk by coating particles on th...
