WEAVING Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth . The warp threads run lengthways of the piece of cloth, and the weft runs across from side to side. In general, weaving involves using a loom to interlace two sets of threads at right angles to each other: the warp which runs longitudinally and the weft (older woof) that crosses it. One warp thread is called an end and one weft thread is called a pick.
YARN PREPARATION PROCESS FOR WEAVING
WARPING The warping process transfers the yarn from multiple packages to a section beam. To produce a quality beam suitable for weaving, the following must be accomplished: 1) no lint, fly, wild yarn 2 ) no high or low selvage 3 ) maintain warper speed 4 ) maintain braking systems 5 ) no crossed or loose ends 6 ) uniform tension across beam 7 ) uniform tension beam to beam 8 ) smooth section beams, rollers
OPERATIONS INVOLVE IN WEAVING In order to interlace warp and weft threads to produce fabric on any type of weaving machine, three operations are necessary : Shedding: Separating the warp threads, which run down the fabric into two layers to form a tunnel known as the shed Picking: Passing the weft thread, which traverses across the fabric, through the shed Beating-up: Pushing the newly inserted length of weft, known as the pick, into the already woven fabric at a point known as the fell
