Warp breakage mechanism of friction spun yarns

Abstract

Warp breakage mechanism of Dref, ring, and rotor spun yarn is discussed using five different techniques,which include Weibull distribution, fatigue behavior, scanning electronmicroscopy studies, and analysis of structural distortion by digital image processing. In all types of yarn, failure occurs at minimum diameter. Interfibre slippage is a dominant factor for warp breakage and the slippage length is found to be highest for Dref yarns.
