Spandex scientific name polyurethane fiber, also known as polyurethane elastic fiber, the international collectively referred to as spandex, is a fiber-forming polymer containing more than 85% of the polyurethane chain produced by the high elasticity of the special chemical fiber.
The main raw materials of spandex are polytetramethylene ether glycol (PTMEG) and diisocyanate (MDI).
Spandex is a linear block **** polymer, the molecular structure contains two kinds of chain segments, soft chain segments to give the fiber to the elasticity of the hard chain segments to give the fiber to the intermolecular interaction force, to ensure that the fiber has a certain degree of strength. Spandex fiber can stretch 5-8 times, elastic recovery rate is higher than 95%, the elasticity is better than any kind of fiber, and has a fine fiber, small specific gravity, aging resistance, dyeing and color fastness, etc., it is a new type of textile raw materials with excellent comprehensive performance. Fabrics only need to add 2-5% of the content, you can reflect the fit, comfort, drape and other characteristics, is the weaving of sportswear, swimwear, women's underwear, hosiery, ribbons, casual wear, high-grade suit fabrics essential textile raw materials, and in the field of medical and health care products, automotive interiors and other industrial textiles are getting more and more use.
