Abstract

Weaving efficiency is affected by a number of factors of which the main being warp breakage rate. These warp breakages can be reduced by sizing the warp yarns with either natural or synthetic sizing agents. Most industries in Ethiopia uses maize starch as sizing agents affecting their weaving efficiency and the quality of fabric they produced. In the present work, polyvinyl alcohol (PVA) and maize starch sizing agents were compared on quality of sized yarns, weaving efficiency and the cost of sizing recipe. Cotton yarns were sized using both sizing agents after which different yarn and fabric properties were tested. Desizing was done enzymatically and its outcome also tested for both sizing agents. The ease of size removal, cost of the size recipes and weaving efficiency were also compared. From all factors considered, PVA sizing agent confirmed to be superior to maize starch in respect to yarn quality produced and the cost of size recipe.
