Elastomeric yams applications

Looking back on the history of sportswear evolution, it is easy to see that not only professional athletes but also average sports enthusiasts have searched for wearable clothes that enable them to elevate their body strength and realize their sports potential. The invention of elastic fiber has delivered multiple advances in the sportswear industry. Nowadays, sportswear characteristics with elastic fiber, including compression, freedom of movement, and comfort, are essential for athletes in most sports. Recently, some new elastic fibers with improving properties and functions have been developed, applied, or have large potential applications in the sportswear industry. In this chapter, the recent developments of elastomeric fibers, elastomeric yams, and fabrics used in sportswear are introduced and discussed. 

Common varieties of elastomeric yams in sportswear include covered and core elastomeric yam for high stretch requirements and textured yam for low to medium elasticity applications. The processing technology for making elastomeric yams is mainly based on conventional methods such as core spinning, cover twisting, and air texturing.
