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.

Embodiment 1

[0038] A kind of method for raising silkworms by adding food to nano-zinc oxide for preparing high-performance silk, at first preparing compound feed, specifically:

[0039] (1) dissolving nano-zinc oxide with a size range of 40 to 200nm in water to make a nano-zinc oxide solution;

[0040] (2) Ultrasonic the nano-zinc oxide solution for 15 minutes to disperse the nanoparticles evenly, stir the nano-zinc oxide solution and silkworm feed evenly, then put it into a microwave oven and heat it for 3 minutes. Feed; Wherein, the quality of water is 2 times of silkworm feed;

[0041] Then add nano-zinc oxide to silkworm artificial feed, that is, silkworm feed, and feed silkworms. The silkworm absorbs nano-zinc oxide and enters the silk gland, and finally combines nano-zinc oxide into silk during the spinning process to obtain high-performance silk;

[0042] Specifically: the silkworms were fed silkworm feed without adding nano-zinc oxide from the first to the fourth instar, and the ...

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 silkworm breeding method for preparing high-performance silk by adding food to nano-zinc oxide 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, which need to be further improved in practical application. Silk itself has a certain ability of anti-ultraviolet and antibacterial, but it is not significant. For example, untreated natural silk did not show obviou...
