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.
Another type of weave is the satin weave, whose weaving method is quite a contrast to the twill weaves. Usually, the weft thread is made to pass under four pieces of warp thread, but goes over just one piece of warp thread. This results in a very delicate and loose fabric that can easily catch a rip.
