Spandex Fabric The Biggest Advantage Is Good Elasticity

Changzhou Haoyuyang Textile Co.,Ltd | Updated: Oct 24, 2017

Spandex is a polyurethane fiber, because of its excellent elastic, it is also known as elastic fibers, clothing fabrics have been a lot of applications. The main features of spandex fabric are:

⑴ spandex elasticity is very high, the general product does not use 100% polyurethane, more in the fabric mix 5 to 30% ratio, the various spandex fabrics are 15% to 45% comfortable elasticity.

⑵ spandex fabric is often made of composite yarn, that is, spandex for the core, with other fibers (such as nylon, polyester, etc.) made of cortex made of core yarn elastic fabric, its good adaptability to the body, it is suitable for tights, No pressure.

⑶ spandex stretch fabric appearance and performance and coated with the outer layer of fabric similar to the similar products.

Spandex fabric varieties

Spandex fabric is mainly used for tight clothing, sportswear, body and the soles of the manufacturing. Its variety according to the needs of the use, can be divided into warp elastic fabric, weft stretch fabric and latitude and longitude two-way elastic fabric.

Spandex fabric use

1, the quality of fabrics and clothing depends mainly on the textile and garment technology, with the raw material fiber is not. Such as some nylon clothing more than ten dollars, and some thousands of dollars. There is no grade between the raw materials of the points.

2, underwear fabrics generally do not use nylon or spandex, and often blended with other fibers and intertwined. Especially spandex, the general content of about 5%.

Spandex fabric the biggest advantage

Spandex fabric is the biggest advantage of good elasticity, can stretch 5-8 times, not aging, spandex can not be individually woven, are generally woven with other raw materials, spandex ratio of about 3-10%, swimwear fabric spandex The proportion reached 20%. Spandex fibers have high elongation at break (more than 400%), low modulus and high elastic recovery rate of synthetic fibers. Multi - block Polyurethane Fiber Chinese Product Name. Also known as elastic fibers. Spandex has high extensibility (500% to 700%), low elastic modulus (200% elongation, 0.04 to 0.12 gpd) and high elastic recovery rate (200% elongation, 95% to 99%). In addition to the larger intensity, the other physical and mechanical properties and natural latex silk is very similar. It is more resistant to chemical degradation than latex silk, with moderate thermal stability, softening temperature of about 200 ℃ or more. Most of the dyes and finishing agents used in synthetic fibers and natural fibers are also suitable for dyeing and finishing spandex. Spandex sweat, resistant to seawater and resistant to all kinds of dry lotion and most sunscreen. Long-term exposure to sunlight or in the chlorine bleach will fade, but the degree of fade with the type of spandex different, very different.
