Sportswear Low-resistance Sports Fabric

In swimming and ski jumping competitions, due to fierce competition, the gap is often within 0.01 seconds. Therefore, for the needs of such athletes, low-resistance functions have emerged. For swimming suits, there are Nylon Superfine Dan High-needle (32G) double-sided warp knitted fabrics blended with nylon yarn and elastic yarn, such as Toray's Acquapin fabric, can reduce frictional resistance in water by 10%. Another product, Acquaspec, has better functionality and can reduce resistance by 15%. It is made of polyester superfine denim through surface finishing. Other companies such as Descente use corrugated processed silk to form very fine grooves on the surface of the fabric to reduce frictional resistance in water. The same design concept is used for air fluid to reduce the resistance of ski jumpers in the air. The Dimplex fabric is a joint collaboration between Descente and Eschler. The corrugated fabric is used to form a convex shape on the surface of the ski jump fabric, so that the athletes can minimize the air resistance during the start, take-off and air flight stages.
