Traditional silk satin handmade quilt technology

First of all, it is necessary to find out what causes silk to harden. There are sericin and mucus on the surface of silk, which can help silkworm babies build nests and cocoons. Because silk is an animal fiber, with the passage of time, fatty protein will decompose, as well as coagulated fat adhesion, which are the main reasons for quilt hardening. Mechanical cocoon peeling is rolled with water in the dry state of silkworm cocoons, which can realize simple working procedures and large output, and is suitable for mass demand. The disadvantage is that the fiber is short, and the quilt will harden in about 3 years. In the market, most of what you see in shopping malls is this type. A cocoon peeling machine costs tens of thousands of yuan, and anyone can afford it. Before artificial cocoon peeling, it is necessary to sort and select the dried cocoons, put them into cloth bags, add a proper amount of soda ash to the cauldron, cook them in boiling water for more than half an hour, and then clean them in flowing water. The purpose is to remove the coagulated fat and sericin in the cocoon, realize the comfort, warmth and durability of the silk quilt, and avoid turning over in ten years. The process of manual cocoon peeling is labor-intensive and inefficient, and young people under 50 can't stand such suffering. The price of semi-finished products peeled by machine in the market is 30-60 yuan lower than that peeled by hand, which shows that the quality of silk peeled by hand is good and precious. People who lobby for a good machine cocoon peeling have ulterior motives.
