Heat Sensitivity: Whilst spandex can withstand An array of temperatures, extreme warmth can result in deformation or injury, influencing its elasticity.
The percentage of set defines the organic elasticity of spandex fiber. Consider a fiber AB elongated to posture C by pulling, and it reaches point D. When the pull is introduced, we observe the fiber doesn’t absolutely return to posture B, demonstrating a Restoration of less than 100%. Therefore
The elasticity and power (stretching up to five instances its size) of spandex is integrated into an array of garments, specifically in pores and skin-tight garments.

The Main spandex is covered to a very good extent as well as Main publicity is a lot less, and since the outer wrapped filaments are wrapped with reverse spiral angles symmetrically throughout the core filaments, the elasticity in the wrapped yarn is well well balanced and will frequently be processed during the afterwards process without shaping cure, even so the processing price of double wrapped yarn is larger. It is mainly used for elastic fabrics like leg guards, elastic belts, sock openings and tights.
