The calculation of raw material requirement and its utilization for given set of production is an important factor of every industry. In woven fabric manufacturing it is required to measure accurate length of the warp required to produce ordered length of the fabric. Many times actual fabric produced from prepared warp is more or less. In weaving many factors decide the length of war consumed for given set of fabric length such as, warp and weft count, EPI, PPI, loom rpm, weaving tension, yarn softness and stiffness etc. This project aims to find the effect of loom speed on the warp contraction percentage of Plain, Twill and Satin weave fabric.
