Forecast of Yarn Breakages During The Weaving Process

Abstract

Weaving process efficiency is determined by factors that take into account the technical condition of the weaving machine, the quality of the used yarns, the workers’ qualification and the climatic conditions. The breakage number of warp and weft yarns for every one metre of woven fabric or during unit time exerts a significant influence on a weaving machine's efficiency. Forecasting breakage number can be determined using different methods. Some of these methods are applied after assembling the article on the weaving machine, while others are applied before that stage.. The forecast of yarn behaviour on the weaving process can be expressed using calculated indexes considering specific elements of yarn stress distribution and breaking strength. The values of these indexes allow one to forecast warp and weft weaving processability and make better decisions in refusing yarnsthat cannot guaranty suitable efficiency.
