Prediction of Weavability of Warp Yarns: A Critical Review

Abstract

Warp yarns undergo various types of complex stress during the weaving process; namely tensile, cyclic-extension, compression, bending and abrasion. The capacity of the yarns to withstand these stresses is termed as their weavability. The prediction ofweavabilityis exploited to extract first-hand information about the expected performance of yarns in weaving. This critical review article discusses several approaches that are adopted by the researchers for the prediction of warp breakages in weaving; namely, empirical, statistical and instrumental. The recent developments in the field of prediction of warp breakage rate in weaving are summarized. The research work that is currently being pursued in the attachment of a microprocessor based shedding device in a constant tension transport (CTT) instrument for the prediction of the weavability of spun yarns is highlighted.
