1. The scientific name of nylon (nylon) polyamide fiber is the general name of polyamide fiber produced in China. Internationally called nylon. High strength, abrasion resistance, good resilience. Nylon is generally used to make jacquard threads. It can be dyed better and has good refractive index. Nylon has good elasticity and can better absorb knitted fabrics on hosiery.
2. Polyester is the main important variety in synthetic fibers, and it is the polyester fiber in my country
The name of the product has a smooth surface, good heat resistance and good wear resistance. The abrasion resistance is second only to the nylon with the best abrasion resistance and poor dyeability
3. Spandex, hydrogen fiber is the abbreviation of polyurethane fiber, and the trade name is Lycra. Spandex is a synthetic fiber whose composition contains more than 85% polyurethane.
There are two varieties of spandex fibers. One is an inlaid copolymer composed of aromatic diisoamidase and hydroxyl-containing polyester segments (polyester spandex for short), and the other is composed of aromatic diisocyanate and hydroxyl-containing polyether Segment mosaic copolymer (referred to as polyether spandex). Spandex fiber, elastic polyolefin fiber and elastic composite fiber are collectively referred to as elastic fiber.
Spandex is generally not used alone, but is incorporated into the fabric in a small amount. This fiber has both rubber properties and fiber properties. Most of the yarn covered with spandex as the core yarn is called elastic core-spun yarn. The surface of this yarn can get a good feel and writing appearance. The outer fiber composed of natural fiber has good wetness.
