The Effect of Mixing Ratio Against Material Properties of Knitted Fabric Made by Blended Yarn with Polypropylene and Cotton

Abstract

The purpose of this study is to investigate relationship between material property and mixing ratio about blended yarn made from polypropylene(PP) and cotton. Material properties were measured by Kawabata Evaluation Sysytem(KES), Japan industrial Standards(JIS) and BOKEN standards. Hardness of fabric was increased by blending of cotton to PP. Resilience of fabric against mechanical defomation was decreased by blending of cotton to PP. Friction of surface was increased by blending PP to cotton because of cross-section of shape of fiber. Water transport ability and thermal insulation performance of fabric were encouraged by blending PP to cotton. The presence of optimal blending ratio for human has been suggested about fabric made by PP and cotton.
