"Woven fabrics are made by interlacing two sets of yarns at right angles to each other"
The lengthwise yarns are known as "warp yarns" (or "ends") The widthwise yarns are known as "filling yarns" (or picks). 2. Basic Function of A Weaving Loom a simplified sketch of a two harnesses loom Basic Components of A Loom
Warp beam Harness Heddle Reed Shuttle or other filling insertion device Cloth bean 3. Basic Weaves: (1) Plain Weave Each warp yarn passes alternately over one and then under one filling yarn for the whole length of the fabric. Basic Weaves: (2) Twill Weave The simplest twill is created by warp yarn crossing over 2 filling and under 1, over 2 and under 1... (2/1 twill). The sequence begins one yarn up. Performance of Twill Weave Fabrics Greater packing of yarns (higher yarn count), fewer interlacing High tensile strength High wind resistance Low wrinkle resistance Low soil resistance Low air permeability Uses of Twill Weave Fabrics Suits Jackets and jeans Sportswear Outwear Working clothing ...
