Problems solved by technology

Due to the influence of factors such as cocoon loading rate, cocoon layer rate and unwinding rate, in the existing silk reeling technology, the silk yield of fresh cocoons is generally only 14% to 16%, which leads to an increase in the production cost of silk. Therefore, some It is necessary to propose a high-efficiency spinning method for silkworm cocoons

Abstract

The invention discloses an efficient silk drawing method for a silkworm cocoon. The method specifically comprises the following steps: (1) soaking the silkworm cocoon in deionized water, and adding 20-30 g / I of white vinegar solution with 3-5% of concentration for processing; (2) taking out the silkworm cocoon soaked and treated in step (1), washing by clear water and drying; (3) placing the silkworm cocoon washed in step (2) in soaking solution prepared by sodium acetate, sodium dihydrogen phosphate, dietary alkali, polyethylene wax, sodium stearate, sodium metasilicate, carbolic acid and water, soaking for 3-4 h; (4) taking out the silkworm cocoon soaked and treated in step (3) and performing hot-washing treatment, wherein a hot water temperature is 60-70 DEG C, and washing for 15-20 min; (5) placing the silkworm cocoon hot-washed in step (4) in cold water for washing; and (6) finally, performing silk reeling operation on the cold-washed silkworm cocoon by using a silk reeling machine. The method is simple in treatment technology process, rational in soaking treatment design of the silkworm cocoon, and beneficial to remove a sericin layer of the silkworm cocoon, and reinforce toughness of a silk, and beneficial to improve a silk drawing rate, wherein the silk drawing rate can be improved to 10.3-10.7%.

Description

technical field [0001] The invention relates to the technical field of silk production, in particular to a high-efficiency spinning method for silkworm cocoons. Background technique [0002] The process of extracting silk from cocoons is called silk reeling. Silk reeling technology originated in ancient China and has a long history. Silk has the advantages of being light and slender, with good luster, comfortable to wear, smooth and plump to the touch, poor heat conduction, moisture absorption and breathability, etc. With the maturity of silkworm breeding technology and silk reeling technology, silk fabrics have really entered the homes of ordinary people. [0003] The traditional silk spinning process includes threading of boiled cocoons, threading, thread collection of cocoon threads, sheath sheathing, reeling, thread addition and threading when part of the cocoon threads are reeled or broken in the middle, and threading of raw silk. Coiled and dried. Due to the influenc...
