Spandex fabric is a new type of synthetic fiber that has many advantages. First of all, spandex fabric has good elasticity and can fit the curves of the human body well, improving the comfort of human clothing. Secondly, spandex fabric has good antibacterial and anti-odor properties, which can effectively prevent the growth of bacteria and avoid stains and odors on clothing. In addition, spandex fabric has good wear resistance, which can extend the service life of clothing and make clothing more durable. Finally, spandex fabric has good breathability, which can effectively reduce the temperature of clothes and keep people comfortable.
Spandex is a kind of elastic fiber and a polymer composed of amino compounds and ester compounds Compound is an elastic fiber among chemical fibers. Spandex is produced by reacting urethane with other amino compounds. Compared with ordinary nylon yarn, the abrasion resistance and heat resistance of spandex yarn have been significantly improved, and it has good elasticity, anti-wrinkle and no ironing, comfortable wearing, and has good resilience and fluffiness.

Good elasticity
Spandex yarn has good elasticity. Its elasticity is the best among all synthetic fibers. Its elasticity can be Reaching 2.5 times or even higher than ordinary nylon yarn. Spandex yarn has good resilience, its resilience can reach 2.5 times or even higher than ordinary nylon yarn, and its wear resistance is also better than ordinary nylon yarn. This is because there are some active groups such as hydroxyl or amino groups in the molecular structure of the spandex yarn. These groups give the spandex yarn good rigidity and dimensional stability, so that the spandex yarn can produce a greater degree of stretch during weaving. This degree of stretch makes the spandex yarn have better wrinkle resistance, thus avoiding wrinkles caused by ordinary spandex during wearing. During the wearing process, this stretchability can also increase the friction between clothing and skin, thereby reducing damage to the skin such as scratches.
Good wear resistance
Spandex has excellent wear resistance , its wear resistance is 30 times higher than ordinary nylon yarn. The wear resistance of spandex can be enhanced as its length increases. Over a longer distance, the wear amount is only 50%-60% of the wear amount of nylon yarn. This is because there is a large amount of curling space in the molecular chain of spandex fiber, so the fiber surface is smooth and smooth. Compared with nylon, spandex yarn has more curling space in the same length. The surface of spandex yarn is smooth, while the nylon fabric has more fine hairs and impurities, so it has good wear resistance; the spandex fabric has a rough surface, while the nylon fabric is smooth and smooth, so it has better wear resistance.

Good high temperature resistance
Spandex has excellent high temperature resistance, and its heat resistance can reach about 150℃. When spandex is blended, interwoven, or used as a composite fabric with other fibers, the anti-wrinkle and iron-free performance of the fabric can be improved. In people’s daily life, spandex has a wide range of applications. For example, the clothes we wear, whether underwear or outerwear, must be worn on the body; the work clothes and various safety protective clothing worn at work also need to use it; it is also used in many sports equipment; outdoor products such as tents and sleeping bags It is even more indispensable.
In daily life, the fibers we use have certain heat resistance, low temperature resistance and light resistance, which determines our choice of fibers. When it comes to clothing fabrics, you tend to choose that has good heat resistance and light-fast fibers to meet our daily needs for clothing fabrics. Spandex fabric is a fiber with good heat resistance and light resistance (the more it is exposed to sunlight, the more shiny it becomes).

Good moisture absorption and breathability
Spandex fabric has good moisture absorption and breathability, and is suitable for sports underwear, casual clothing, and casual wear., children’s clothing, etc., such as elastic vests, elastic sports socks, etc. Spandex fabric not only has good elasticity, but also has good breathability. Under normal circumstances, it can dissipate the waste heat generated by the human body. Therefore, spandex yarn has good moisture absorption and breathability properties.
Spandex fabrics are generally yarn products spun from high-elastic nylon or lyocell fiber as raw materials. This type of product has good elasticity and resilience, feels soft, plump and elastic, and can be blended or interwoven with other fibers for the production of knitted products. Therefore, both high-elastic nylon and lyocell fiber can be used to make spandex fabric clothing products. However, it should be noted that the spandex fiber fabric should not be too thin, otherwise it will also affect the overall quality and moisture absorption and breathability of the fabric.
In short, spandex fabric has good elasticity, antibacterial, anti-odor, wear resistance and breathability, which can improve the comfort of human clothing and make people more comfortable and healthier.
