Silk, a textile, with silk or synthetic fibers, rayon, short silk and other woven; with pure silk or rayon woven or interwoven fabric of the general term.
In ancient times, silk was silk (mainly silk, but also a small amount of tussah silk and cassava silk) woven textiles. Modern Due to the expansion of textile raw materials, all the longitude using artificial or natural filament fiber woven textiles, can be called a broad sense of silk. The pure silk weaving silk, also known as "real silk."
Silk is a specialty of China. The ancient Chinese working people invented and mass-produced silk products, opening the first large-scale business exchange between the East and the West in world history. Starting from the Western Han Dynasty, China's silk has been shipped abroad in large quantities and became a world famous product. At that time, the road from China to the West was called "the Silk Road" by Europeans, and China was also called a "silk country."
1: to wear comfortable. Silk is composed of protein fibers and has good biocompatibility with the human body. Combined with smooth surface, the coefficient of frictional stimulation of human body is the lowest among all kinds of fibers, only 7.4%.
2: suction, put wet good. Silk fibroin is rich in amino groups (-CONH), amino (-NH2) and other hydrophilic groups, and because of its porosity, easy diffusion of water molecules, so it can absorb moisture in the air or water, and Maintain a certain amount of moisture Under normal temperature, it can help the skin to maintain a certain degree of moisture, not to make the skin is too dry; in summer wear, but also the body's sweat and heat quickly distributed, people feel cool.
Silk not only has good heat dissipation, there is a good warmth. Its thermal insulation benefits from the porous fiber structure. There are many tiny fibers in the silk fiber, which are composed of more fine fibers. Therefore, more than 38% of seemingly solid silk is actually hollow, and there is a lot of air in these voids, preventing the heat from being dissipated and giving silk a good warmth
3: Sound absorption, vacuuming, flame retardant. Silk fabric has a higher porosity, which has good sound absorption and suction, so in addition to making clothing, but also can be used for interior decoration. As the silk has moisture absorption, moisture release and moisture retention, aspiration and porosity, but also adjust the indoor temperature and humidity, and can be harmful gases, dust, microorganisms sucked off. In addition, the thermal denatured silk fiber is small, relatively heat-resistant, heated to 100 ℃, only about 5-8% of embrittlement, and most of the synthetic fiber thermal deformation 4-5 times larger than the silk. Silk burning temperature 300-400 ℃, is a flame retardant fiber, and synthetic fiber combustion temperature 200-260 ℃, that is flammable and fusible. Therefore, the use of silk fiber as a raw material for interior decoration, not only can play a sound-absorbing, vacuuming, heat preservation, but also play a flame retardant function.
4: health care. Silk fiber health care function is irreplaceable, which contains the human body must have 18 kinds of amino acids, amino acids contained in human skin is almost the same, so there are human "second skin" reputation. Wear silk clothes, not only to prevent UV radiation, defense of harmful gases intrusion, to resist harmful bacteria, but also enhance the vitality of body surface skin cells and promote skin cell metabolism, while some skin diseases have a good adjuvant therapy.
Easy wrinkles, easy to inhale, not strong enough, fast fading, not warm.
