Studies on tensile properties of eri/acrylic blended yarn

Abstract

Eri/acrylic blended yarn has been prepared at different blend ratio in ring spinning system following draw-frame blending technique. The Box and Behnken design for three variables and three levels has been used to study the influence of count of the yarn spun (Ne), twist multiplier and proportion of eri fibre in the blends on some important tensile properties of the yarns produced. The chosen level of variables remaining within the industrially acceptable limits shows that fibre parameters and yarn parameters are the determining factors to influence yarn tensile properties.
