What are the benefits of spandex clothes?
- Jun 12, 2018 -

The biggest advantage of spandex fabric is its good elasticity, which can be stretched 5-8 times without aging. Spandex can not be woven alone. Generally it is woven together with other raw materials. The proportion of spandex is between 3-10%. The proportion of up to 20%, spandex fiber with high elongation at break (above 400%), low modulus and high elastic recovery of synthetic fibers. The multi-block polyurethane fiber is the Chinese trade name, also known as elastic fiber. Spandex has high extensibility (500% to 700%), low elastic modulus (200% elongation, 0.04 to 0.12 g/denier), and high elastic recovery (200% elongation, 95% to 99%).

In addition to its high strength, other physical and mechanical properties are very similar to natural latex filaments. It is more chemically resistant than latex filaments, has moderate thermal stability, and has a softening temperature above about 200°C. It is used for synthetic fibers and natural fibers. Most dyes and finishing agents are also suitable for the dyeing and finishing of spandex.

Spandex is resistant to sweat, seawater, and a variety of dry cleaners and most sunscreens. Exposure to sunlight or chlorine bleach may also fade, but the degree of discoloration varies with the type of spandex.
