Weft Knitting Manufacture. Weft knitting is a knitted piece of fabric where the stitches run from left to right horizontally across the fabric. It is usually knitted with one piece of yarn, and can be made either by hand or using a knitting machine.
âWarp,â on the other hand, comes from an Old Norse word, varp, which means âthe cast of a net.â The warp of a fabric, in other words, acts like a net to capture the weft, holding these threads firmly so that they will not escape, causing the textile to unravel. Collectively, the warp and weft compose a piece of fabric.
