Weavability limit is a significant factor to determine whether or not a particular fabric construction can be produced on a loom. In this study, the weavability limit of finer cotton yarns is assessed for two different fabric structures (plain, twill). For this purpose, the acceptable weavability limit of three different cotton yarns (60 Ne, 72 Ne,and 80 Ne) are determined. The maximum weft density that can be achieved for a specific structure upto frequent breakage is defined as the weavability limit for that particular count. Indeed, the yarn count plays a significant role in determining the weavability limit. The finer the yarn, the more weavability limit can be attained. The reason behind this phenomenon is that more PPI can be inserted in a given space in case of finer yarns rather than the coarser yarns. Moreover, the weavability limit varies for different fabric structure. This variability of the weavability limit values for plain and twill structure is demonstrated andrationalized by fabricgeometry analysis.
