Why We Call Silk “the Queen of Fiber”
From www.finesilk.topIt is known to all that silk has always been taken as a kind of noble fabric since ancient times. Why is it so popular till now? Today we are going to know more about its characteristics and health care functions.
1. the composition and structure of silk fiber
In order to illustrate that we shall begin with the composition and structure of silk fiber. Silk is mainly composed of fibroin and sericin, accounting for 70-90% of the total. It also contains a small amount of pigments, oils, waxes, sugars and inorganic substances.
The molecular chain of silk is composed of two types of chain segments, a part of which is mainly composed of glyoxyline and serine residues, and many ammonia chains are formed between the chains, forming the crystal zone in the fiber. The other part is composed of amino acid residues with large and complex side chains. The blocking effect of branch chain makes the structure form loose amorphous region.
Silk fiber is composed of two parallel monofilaments, the main body of which is fibroin, which is surrounded by sericin.
The cross section of silk fiber is triangular, the three sides are similar, and the angle is slightly round and blunt.
2. health care functions of silk fiber
Because of the special composition and structure of silk fiber, it has a variety of merits that is beneficial to our healthy. It contains 18 kinds of amino acids which are of great nutritional value to human body and its benefits will be stated as follows:
2.1 The protein fiber of silk has excellent biocompatibility with human body, the lowest friction and stimulation coefficient for human body among all kinds of fibers, and has a good feeling of skin affinity and comfort. It is known as "the second skin of human body".
2.2 Silk has a variety of hydrophilic genes. Because of its porous nature, it is easy for water molecules to diffuse. It can absorb and dissipate water in our body to keep the skin in a certain humidity. The fibroin contains a substance called "hydrophilic side chain amino acid", which can help to remove the sweat and heat to make people feel particularly breathable and cool, especially for those who are with rheumatism, arthritis or periarthritis of shoulder.
2.3 Tryptophan and chromic acid in silk can absorb ultraviolet rays, which is of good anti ultraviolet function in skin protection.
2.4 Serine, threonine and leucine in silk can promote cell metabolism, accelerate wound healing and prevent skin aging.
2.5 Silk is the softest and lightest fiber in the world. It is warm in winter and cool in summer, and has little pressure on human blood vessels, which is conducive to human microcirculation. The fine molecules (sleep factors) emitted by 18 kinds of amino acids can ease human nerves and improve sleep quality.
2.6 Sericin of silk can nourish the skin and prevent the growth of mites and bacteria, especially for those who are skin allergic.
