A STUDY ON THE MECHANISM OF FABRIC “WAVE” PLASTICITY

Test of pulling out yarns from fabrics was designed to study the mechanism of fabric “wave” plasticity. F that frictional forces per area in the warp and weft interlacing unit was proposed to characterize the frictional forces between yarns in fabrics. Results showed that the values of F of the fabrics with better fabric “wave” plasticity were bigger. Furthermore, in order to further understand the mechanism of fabric “wave” plasticity and test the application value of F, correlation analysis was carried out between F and fabric’s mechanical index which could represent fabric “wave” plasticity. It was found that F and the mechanical index had a high positive correlation. Therefore, it can be concluded that fabric “wave” plasticity is the reflection of frictional forces in fabrics. Moreover, the values of F could be used for characterizing the frictional forces in fabrics
