    Silk is a natural protein fiber prepared by silkworm, and then carefully compiled from the textile, silkworm attack usually starts from the mulberry when the germination, silkworm attack is called the green period, to the air Circulation, proper temperature and humidity indoor maintenance 12-13 days. The antworm that hatched and hatched from the silkworm was as long as 3 mm long and 0.5 mg in weight. After mulberry leaves were raised for 25-28 days, the silkworm was 7.5-9 cm long before it matured. About 4-5g in weight, during the entire larval rearing period, on humidity aeration, feeding leaves, removing silkworm excreted silkworms and broken leaves, to silkworms after silkworms are mature, is a series of more detailed processes.

   After the silkworms are cooked on the tufts, the next step is to wind the filaments. To prevent cocoons from cocooning moths during storage, simple bake-killing devices use heat to kill live cockroaches in the cocoon cavity and remove the right amount of water. There are many ways to reel silk, according to different types of cocoon cocoon ups and downs, it can be divided into three types: floating, semi-floating and sinking. The sinking of cocoon mainly depends on the amount of water absorbed in the cocoon cavity after cooking. The boiled raw silk will be passed through the process of processing, arranging the thread, arranging the thread, expelling sheath, collateralizing, coiling, and boring. After silkworms are made into raw silk by twisting, they enter the silk stage. A silkworm's life-spanning spit is 1,000 meters long. It takes 111 cocoons to make a tie, and 630 cocoons are required to make a lady's coat.

  Silk is the fiber that silkworms spit on mulberry trees. Silk is an ecologically non-polluting natural fiber. With other fibers and processed products have no alternative common performance and unparalleled vitality. After dyeing and weaving a variety of colorful silk fabrics, it is easier to sew and process various high-grade clothing and interior decorations, tourist souvenirs and many arts and crafts. No wonder foreign consumers hailed silk as the source of beauty.
