Weaving Technology

Weaving is the most popular way of fabric manufacturing. It is primarily done by interlacing two orthogonal sets (warp and weft) of yarns in a regular and recurring pattern. Actual weaving process is preceded by yarn preparation processes namely winding, warping, sizing, drawing and denting.

Winding converts the smaller ringframe packages to bigger cheeses and cones while removing objectinable yarn faults. Pirn winding is performed to supply the weft yarns in shuttle looms. Figure 1.2 shows various yarn packages used in textile operations (from left to right: ringframe bobbin or cop, cone, cheese and pirn). Warping is done with the objective to prepare a warper’s beam which contains a large number of parallel ends in a double flanged beam. Sizing is the process of applying a protective coating on the warp yarns so that they can withstand repeated stresses, strains and flexing during the weaving process. Finally the fabric is manufactured on looms which perform several operations at proper sequence so that there is interlacement between warp and weft yarns and continuous fabric production.
