Analysis of tensile properties of dref-III blended yarns

Abstract

Efforts have been made to use same blended stock of materials in both core and sheath of dref-III yarn to make the blend percentage independent of core-sheath ratio and to have proper blend homogeneity, Polyester and viscose fibres have been used to prepare their blends at different blend ratios and their tensile characteristics thoroughly studied, It is observed that the Hamburger's model based on stress-strain curves of 100% polyester and 100% viscose yarns can be successfully used to predict the tensile strength of blended yarns, A generalised regression equation has been derived from the Hamburger's model which can predict the tensile strength of blended yarn with high level of accuracy.
