The Polyester Yarn has a spring-like appearance. After the fabric is dyed and finished, the elastic crimping property (Self Crimp) is increased, which gives the fabric good elasticity, elastic recovery and fluffiness. It has low temperature dyeable properties and can be used in combination with natural fibers such as Cotton and Acetate, or for applications such as Hard core wrapping. After the dyeing and finishing, the Polyester Yarn has a natural turning phenomenon, so that the surface of the fabric has a natural appearance and is suitable for knitting and woven fabrics.
