“…Shed is produced in the weaving process by the abrasion of yarn against yarn, and yarn against metal. This also causes yarn rupture as a sufficient number of fibres are rubbed off (Abrams et al, 1956).…”

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.

The effect of certain variables (size add-on, degree of polymerization of size, and temperature of application) in sizing was determined in relation to simulated weaving for a cotton yarn sized with poly(ethylene oxide). Increasing the size add-on decreased the tendency of the sized yarns to shed fibers and size. The effect of resin DP varied with size add-on. At low add-ons an increase in DP was accompanied by an improvement in weavability which was attributed to the concomitant increase in toughness of the resin; after very high values of DP were reached, however, weaving became unsatisfactory, apparently because of poor anchoring of resin to yarn. At high add-ons an increase in resin DP resulted in improved weaving performance for all ranges of DP, and this effect was attributed both to the increase in toughness of the resin film and to the increase in film coverage of the yarn surface and in film thickness achieved at high add-ons. As the temperature of application was raised, penetration of size through yarn increased. This resulted in poor weavability at low DP's; at high DP's, however, weavability was improved, apparently because the increase in temperature permitted better anchoring of size to yarn.

Earlier work at ATIRA has shown that there exists a quantitative relationship between warp-breakage rate and grey cotton yarn quality. This work attempts to restructure the earlier formula in such a way that it can be used to predict individually the relative contributions of three factors: the general inadequacy of yarn to withstand the load, stretch, and abrasion imposed on it during weaving; the obstruction or tensile/abrasive failure of thick places; and the failure or obstruction of knots and other miscellaneous faults. The formula has also been extended to blend yarns, and the accuracy of prediction is quite high.
