What are the characteristics of silk?
In nature, silkworms have the characteristics of spining a cocoon. The Chinese found that collecting and tidying silk can be woven into a silk that is comfortable, light, and hygroscopic. Wearing silk clothing has become a symbol of wealth and status. Although silk is expensive, it is still selling well in Europe and Asia, so that the road to transport it is called the silk Road. However, do you know what’s the strengths and weaknesses of silk?
Comfortable to wear. The silk is composed of protein fiber, which has good biocompatibility with the human body and has a smooth surface. Its friction coefficient to the human body is the lowest among all kinds of fibers, only 7.4%.
Good hygroscopicity and moisture release. At normal temperatures, it helps the skin retain a certain amount of moisture without leaving the skin too dry. When you wear it in the summer, you can quickly dissipate the sweat and heat from the body, making you feel cool. silk not only has good heat dissipation performance, but also has good thermal insulation. Actually, more than 38% of the seemingly solid silk is hollow. There is a large amount of air in these gaps, which prevent the heat from being emitted and makes the body warm.
Sound absorption, vacuuming, and flame retardant. Silk fabrics have a high void ratio and thus have good sound absorbing and air absorbing properties, so they can be used for interior decoration in addition to clothing. Because silk has moisture absorption, moisture release performance, moisture retention, air permeability and porosity, it can also adjust indoor temperature and humidity. What's more, it can absorb harmful gases, dust and microorganisms.
Anti-UV. The tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has a good anti-ultraviolet function. Ultraviolet rays are very harmful to human skin. However, after absorbing ultraviolet rays, the silk itself undergoes chemical changes, so that the silk fabric is easily yellowed under the illumination of sunlight.
Health care. The health function of silk fiber is irreplaceable. It contains 18 kinds of amino acids necessary for human body, which is similar to the amino acid contained in human skin. Therefore, it has the reputation of human second skin. Wearing silk clothes not only can prevent harmful gas from invading, resist harmful bacteria, but also enhance the vitality of skin cells on the surface, promote the metabolism of skin cells, and have a good auxiliary therapeutic effect on certain skin diseases.
Silk is easy to wrinkle. Because it has a smooth surface, the folds will destroy the beauty. In addition, silk is easily stuck to the body, fragile, and faded easily.
Silk is popular because of its material characteristics. Therefore, silk products can be found in people's lives frequently, such as silk pillowcases, silk pajamas, silk eye mask.
