Modern fabric technology has come a long way to help people keep cool, and it's become a huge part of the athletic apparel industry. You've probably heard of fabrics that "wick away moisture," but you may not know what that means. Just like a candle draws wax up the wick to the flame, wicking fabric pulls moisture from the body to the exterior of the shirt where it can evaporate more easily.
Many wicking fabrics are made from polyester blends. Synthetic materials don't retain moisture like natural fabrics do. Polyester holds on to only about 0.4 percent of moisture; cotton just 7 percent. Unlike regular polyester, though, wicking fabrics are woven in such a way that the moisture is forced into and through the gaps in the weave so it can find the outer shell of the material. The weave itself makes the material highly permeable.
These materials help to cool down the temperature of the body, ensure skin breathing and make sweating invisible.
These materials we are using to produce our sportswear.
