METHOD AND COMPUTER-ASSISTED PROGRAM FOR FORECASTING WORKABILITY YARNS IN THE WEAVING

Summary/Abstract: Weaving process efficiency is influenced by several factors including a significant proportion have characteristics of processed yarns. This paper presents a method of forecasting foundation and processing of warp and weft yarns on unconventional projectile weaving machines. Workability is appreciated on physical and mechanical properties of the yarns purchased. It aims at estimating the number of breaks of warp yarns and the number of weft yarn breaks in the weaving of a meter of woven fabric. The number of breaks is significantly influenced by deficiencies of quality yarns, the yarns tension system on the weaving machine and the variation of tensile strength / tensile yarns (coefficient of variation). Method exposed in the paper is focused on mathematical modeling of specific phenomena and the weaving process using a suitable computer program, computer-based simulation that allows multiple threads specified characteristics and provides scientifically elements weaving technology forecasting their workability. Elements provided by computer-aided design software allows analysis, interpretation and proper adoption of the optimal solution for a given situation so that decision rejecting inappropriate lots of yarns to be done before placing on technological flow.
