Description
Technical Field
The invention relates to a silkworm breeding method for improving the moisture absorption performance of silk, and belongs to the technical field of silkworm breeding.
Background
The silk fiber is mainly composed of two major parts of fibrous silk fibroin and spherical sericin. The sericin is secreted from the middle silk gland of silkworm body, and when silking cocoons, the silk fibroin fibrils in the back silk gland pass through the middle silk gland, the sericin is attached to the surface of the silk fibroin to lubricate, bond and protect the silk fibroin. In the raw silk fiber, the sericin content is about 20-30%, and phosphorus-shaped particle sheets are irregularly coated on the surface of the silk fiber. The dissolubility of each layer of sericin is gradually reduced from outside to inside, wherein the dissolubility of the sericin at the outermost layer is the best, and the moisture absorption performance is also the best. However, silk fabrics with sericin retained have the problems of poor gloss and uneven dyeing, poor fabric softness, poor wearing comfort and the like, so that in the production process of silk textiles at home, silk reeling, refining and other operations are required to almost remove sericin on the surface of silk. Although the water absorption of the degummed silk fiber is still higher than that of the cotton fiber, the silk is a nearly thin fabric due to the high price of the silk, the total water absorption of the fiber is low, and the defect of insufficient moisture absorption performance still exists.

The first purpose of the invention is to provide a silkworm breeding method for improving the moisture absorption performance of silk, which is realized by adjusting the temperature and the humidity of the silkworm in the 5 th larva stage of the silkworm, specifically, the temperature is controlled to be 24-25 ℃ and the humidity is controlled to be 60-65% on the 1 st-3 rd day of the silkworm with the 5 th age; controlling the temperature at 30-32 deg.C and humidity at 65-70% on the 4 th-5 th day of 5 years old; controlling the temperature at 22-23 deg.C and humidity at 60-65% on 6-8 th day of 5 years old.
According to the invention, the temperature and the humidity are adjusted in the 5-year stage, the secretion of sericin is adjusted, and especially the expression of sericin in the middle-rear silk gland cells is adjusted, so that part of sericin can be mixed with fibroin and coated in the sericin secreted by the front silk gland cells, and finally, the degummed silk fiber has better hygroscopicity and does not influence the toughness, the serviceability and the glossiness of the silk fiber.
