Abstract
The purpose of this study is to evaluate the material properties of the knitted fabric with polypropylene (PP) blended yarn. The material properties were measured by Kawabata Evaluation System (KES), Japan Industrial Standards (JIS) and BOKEN standards. The functionally effect by blending appeared as specific gravity and water & heat transport property. The radius of yarn became smaller and the number of fiber became greater by blending because the weight of PP was light. Resilience against mechanical deformation became greater by blending. Moisture transport property could be added to PP fabric unless spoiling the characteristic of PP such as low thermal conductivity and hydrophobic by blending of the modified cross-section polyester.
