Polyester jacquard lining, polyester spinning, nylon spinning – introduction to silk properties and uses
Features
, comfort. Real silk is composed of protein fibers and has excellent biocompatibility with the human body. In addition, its surface is smooth, and its frictional stimulation coefficient to the human body is the lowest among all types of fibers, only 7.4%. Therefore, when our delicate skin meets smooth and delicate silk, with its unique soft texture, it follows the curves of the human body, considerately and safely caring for every inch of our skin.
Second, it has good moisture absorption and release properties. Silk protein fiber is enriched with many hydrophilic groups such as amine groups (-CHNH) and amino groups (-NH2). Because of its porosity, it is easy for water molecules to diffuse, so it can absorb or emit moisture in the air, and Stay hydrated. Under normal temperatures, it can help the skin retain a certain amount of moisture and prevent the skin from being too dry; when worn in summer, it can quickly dissipate sweat and heat discharged from the human body, making people feel extremely cool. It is precisely because of this performance that silk fabrics are more suitable for direct contact with human skin. Therefore, people regard silk clothing as one of the necessary summer clothes.
Silk not only has good heat dissipation properties, but also has good warmth retention properties. Its thermal insulation properties are due to its porous fiber structure. There are many very small fibers in a silk fiber, and these small fibers are composed of even smaller fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow. There is a large amount of air in these gaps. This air prevents the dissipation of heat and makes the silk have good warmth retention properties.
Third, sound absorption, dust absorption, and heat resistance. Silk fabric has a high porosity, so it has good sound absorption and air absorption. Therefore, in addition to making clothing, it can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall coverings, etc. Decorating a room with silk decorations will not only make it spotless but also keep it quiet. Because silk has moisture absorption and release properties, as well as moisture retention, breathability and porosity, it can also adjust indoor temperature and humidity, and absorb harmful gases, dust and microorganisms. In addition, silk fiber has little thermal denaturation and is relatively heat-resistant. When it is heated to 100°C, it only embrittles about 5 to 8%, while the thermal deformation of most synthetic fibers is 4 to 5 times greater than that of silk. The burning temperature of silk is 300~400°C, which makes it a flame-retardant fiber, while the burning temperature of synthetic fiber is 200~2600°C, which is flammable and fusible. Therefore, using silk fiber as a raw material for interior decoration can not only play the role of sound absorption, dust collection, heat preservation, but also have flame retardant function.
Fourth, UV resistance. The tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has good anti-ultraviolet function. Ultraviolet rays are very harmful to human skin. Of course, after silk absorbs ultraviolet rays, it will undergo chemical changes, making silk fabrics prone to yellowing under sunlight.
Usage
Silk is an ecologically non-polluting natural fiber. It has unique properties and unparalleled vitality that are irreplaceable by other fibers and processed products. Various colorful silk fabrics made by dyeing and weaving are easier to sew and process into various high-end garments, interior decorations, tourist souvenirs and many arts and crafts. No wonder foreign consumers regard silk as the “source of beauty”. Silk clothing made of real silk has a health-care effect on the human body.
