ABSTRACT
Two sets of yarns, namely warp and weft, are needed for the formation of a woven fabric. Warp yarns are usually stronger and more compact than the weft or filling yarns. In view of its relative softness, the weft yarn is expected to flatten out in the woven fabric and fill up the open space that arises out of gaps between yarns. Hence, the weft yarn is also termed as the “filling” yarn. Warp is supplied in the form of a sheet, wrapped around a barrel that is known as a weaver’s beam, to a weaving machine called a loom. A warp sheet is stretched along the length of a loom and taken through various guiding elements to the weaving zone. The weft yarn is supplied in a suitably packaged form, which is carried to the weaving zone by a shuttle. A shuttle passes through splits created in the warp sheet, dragging the weft yarn along.
