Silk originated in China. It was said that in the Yellow Emperor era more than four thousand years ago, it began to teach people to raise silkworms and make clothes.

Silk generally refers to silk, including mulberry silk, tussah silk, castor silk, cassava silk and so on. Silk has been favored by people from all ages through its unique charm. Silk belongs to protein fiber. Silk fibroin contains 18 kinds of amino acids which are beneficial to human body. It can help skin maintain the metabolism of the surface lipid membrane, so it can keep the skin moist and smooth.

　　 silk It is the only natural filament fiber that has been applied in practice and solidified by the modification of the silkworm mucus. Silkworm fiber is divided into different kinds of silkworms because of their eating habits, including mulberry leaves, mulberry silk fibers, tussah silk fibers formed by eating oak leaves, and other wild silk fibers formed by cassava leaves, horse mulberry leaves and castor leaves. Mulberry silk fiber and tussah silk fiber can keep the form of filament fiber in the filament yarn formed by cluster. Other kinds of wild silk fibers can only be changed into short fibers for textile processing. In the filament yarn formed by mulberry silk fiber and tussah silk fiber, mulberry silk fiber Filament yarn Most importantly, the majority of natural filament yarn.

1. Silk is made up of sericin and silk fibroin. It consists of 18 amino acids in different proportions and space. It is a kind of protein fiber. Sericin is closely linked to silk fibroin. Sericin is loose in structure and rough in hand, so it needs to be degumming, and its silk structure is compact. Hikaruzawa Youwa and Liang Liang have pearl like luster.

2. The handle is soft, smooth, thick, plump and elastic.

3. It has good moisture absorption and breathability, and has skin care function. Silk is protein fiber and silk carpet woven with silk has good UV absorbency. Silk is a porous fiber, so it has good thermal insulation, moisture absorption, moisture dissipation and breathability, and has a certain protective effect on the skin.

4, silk is relatively delicate, should be carefully care, avoid gravitational friction twist or drag in rough places, resulting in protein fiber damage.

Silk fabric, it is the best in the world. Spin Raw materials, clothes made of it, the price is also very expensive. To get silk powder, we must learn to identify the good or bad silk, or get the price very expensive, but the quality of the clothes are not good, no one has been criticized.

Here are some simple ways to distinguish silk from good or bad.

90% off: hand tighten the fabric and then let go. The silk is basically elastic without any creases. The artificial silk has obvious creases and is difficult to recover quickly.

2. touch: silk feels like a handle, and chemical fiber has no such feeling. Although artificial silk feels smooth and soft, it is not smooth.

3. pull: pull out a few yarns, moisten part of it with water, and then pull it off. For example, artificial silk is broken from wet place, and the broken ends are all silk like products with different lengths.

4. grasp (grinding): the friction between the two layers of fabric will produce "silk" or "Silk sounding", while the fabric of other materials is not.

5. combustion: part of the yarn burning, silk can not see the naked flame, burning hair taste, black particles, can be kneaded by hand, the simulation silk fire flame, plastic smell, after the fire extinguished after leaving the hard rubber block.

If we want to buy real silk, we need to know the real way.
