Abstract

Due to the change in lifestyle, new sensible materials for sportswear and outdoor are needed. This study is conducted in order to obtain the data for sensible materials through nylon twist process. 1-step nylon twisting machine was used to set the optimum twist process. DSC measurements of twisted nylon yarn showed crystallization temperatures around 170℃ and melting temperatures around 220℃. Nylon 40D/13F DTY and Nylon 50D/48F DTY showed optimal results at 160℃, 1,500 T/M(Turns per meter), and Nylon 70D/68F DTY at 160℃, 1,200 T/M(Turns per meter) after 1-step twist process. Also, Nylon 40D/13F DTY was confirmed to have inter-layer property deviation of ±5 percent.
