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 has some functions of the added particles, and the applicable range is narrow.

Abstract

The invention relates to a nano-zinc oxide feeding silkworm rearing method for manufacturing high-performance silk and a product thereof. The nano-zinc oxide feeding silkworm rearing method includes steps of adding nano-zinc oxide into artificial feed of silkworms, feeding nano-zinc oxide into silk gland of silkworms by an absorbing and converting function of the silkworms and cocooning to obtain high-performance silk containing nano-zinc oxide. On the premise of not damaging natural quality of the silk, the silk is modified and has better mechanical performance and better sterilization and ultraviolet resistance property.

Description

Technical field [0001] The invention belongs to the field of silk fiber and its modification, and relates to a method for preparing high-performance silkworm silk by adding nano-zinc oxide feeding and breeding silkworm and its products. Background technique [0002] The spinning solution composed of protein secreted by the silk glands when the mature silkworm forms cocoons, and the continuous filament formed by solidification in the air is called silk. As a biological fiber, silk not only has good gloss and comfortable touch, but also has strong mechanical properties and good biocompatibility. It is widely used in textiles, medicine, cosmetics and biological fields. [0003] The breaking strength of degummed silk is about 400MPa, the breaking elongation and breaking energy are about 15% and 30J / g, which need to be further improved in practical applications. The silk itself has certain anti-ultraviolet and antibacterial ability, but it is not significant. For example, the untreated...
