How to Identify Real Silk and Chemical Fiber Silk
1. Observe the gloss. The luster of real silk is soft and uniform, bright but not dazzling. Although the luster of artificial silk fabric is also bright, it is not soft and smooth to the eye. Although the luster of polyester yarn is uniform, it has a shiny or shiny texture. Nylon silk fabric has poor luster, as if coated with a layer of wax.
2. Hand touch sensation. When touching real silk fabrics, there is a feeling of pulling hands, while other chemical fiber products do not have this feeling. Artificial silk fabrics are smooth and soft, but not crisp. Cotton silk fabric feels harder but not softer by hand.
3. Carefully examine the creases. When the hand tightly grips the silk fabric and then releases it, it has good elasticity and no creases. Artificial silk fabrics have obvious creases after being released, and the creases are difficult to restore to their original state. Although nylon silk has creases, it can slowly recover to its original state, so do not be fooled by its false appearance. Therefore, do not be deceived by its false appearance.
4. Test fiber tension. Extract a few fibers from the edge of the fabric and wet it with your tongue. If it is easy to break at the wetting point, it indicates artificial silk. If it is not broken at the wetting point, it indicates real silk. If the fiber has good strength in both dry and wet conditions, it is nylon or polyester silk that is not easy to break.
5. Listen for friction sounds. Due to the silk surface being protected by sericin and resistant to friction, dry silk fabrics will make a sound when they rub against each other, commonly known as "silk chirping" or "silk chirping"; However, other chemical fiber products showed no sound.
The company was established in April 2003. It mainly produces various products such as nylon "6" high-speed spinning POY, elastic yarn DTY, network yarn HOY, conventional spinning draft yarn, etc., widely used in chemical fiber stretching, weaving, clothing, etc. There are currently 20 sets of advanced equipment with an annual output of over 20000 tons. With strong technical strength and strict quality management, we are committed to producing high-quality products. And has won unanimous praise from a large number of customers, and has developed into a well-known enterprise in the industry. On the basis of consolidating traditional products, the company continuously develops new products, pursues innovation, strives for progress, is based on integrity, and puts service first. We warmly welcome domestic and foreign customers to come for cooperation and trade negotiations.
Polyamide, also known as nylon silk, is mainly used for synthetic fibers. Its most prominent advantage is that its wear resistance is higher than all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to blended fabrics can greatly improve their wear resistance; When stretched to 3-6%, the elastic recovery rate can reach 100%; Can withstand tens of thousands of twists and turns without breaking.
Nylon can maintain the bending deformation formed during heating. Its long filaments can be made into elastic filaments, while its short filaments can be blended with cotton and acrylic fibers to improve their strength and elasticity. In addition to being used in underwear and decorations, it is also widely used in industrial fields such as cord threads, transmission belts, hoses, ropes, fishing nets, tires, parachutes, etc. Its wear resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber, making it extremely durable.
Nylon is the trade name for polyamide fibers, also known as nylon. The focused state structure of nylon is closely related to the stretching and heat treatment during the spinning process. Nylon twisted yarn is mainly made of long fibers, and there are also a small amount of nylon short fibers. Nylon twisted yarn is suitable for knitting and weaving, covering all fields of textiles.
China is a major producer of nylon civilian fibers, and the future development space is still very broad. However, compared to its position as a major producer of nylon, China's nylon industry still urgently needs to enhance its strength in areas such as product application development, brand expansion, and cultural construction. The era of nylon industry expansion relying on scale and quantity has come to an end, and changes in labor and other related factors have led the industry into a new era that requires changes in development methods, structural adjustments, and transformation and upgrading. It needs to rely on technology, culture, brand, and innovation to drive the overall upgrading of the industrial chain value.
In July and August of this year, polyester filament manufacturers generally gained a lot. Due to tight supply, FDY products have a high profit level per ton. DTY and POY products have relatively weak returns. DTY products benefit from the lag in price changes, and their profit level decreases slowly during the period of POY price decline. Although POY began to turn losses into profits in early July, it fell to the edge of profit and loss in mid to late September.
