Abstract

The eight weavable singles yarns studied in Part 1 of this paper were all woven plain weave and the end breaks identified by cause and recorded. End breaks were found to be due to failed splices, abrasion failure and thin places. The incidence of thin-place breaks was found to increase with increasing irregularity (CV%) of the yarn, and as the linear density of the yarn decreased. It is primarily the thin-place end breakage rate which determines the yarn count limit for acceptable weavability, and this is shown to depend on the evenness of the yarn. It is shown how to predict the thin-place end breakage rate from the yarn, fabric and loom parameters.
