Normally the fabric is formed vertically and the loops are formed horizontally. It is the most common fabric formation technique for knitted fabric. It is usually knitted with one piece of yarn, and can be made either by hand or using a knitting machine. Weft knitting is the most common form of knitting as it is simpler than warp knitting, the other form of knitting. There are four basic weft knitted fabric structures: interlock, purl, plain, and rib. The action of the needle during loop formation produces all these distinct weft knitted structures. On the basis of the type of weft knitting machine, the weft knitted fabric can be classified as single jersey or double jersey. Warp knitting: The second knitting method is termed warp knitting, though its share in the production of knitted fabric is low compared to weft knitting but it is used in technical areas. In warp knitting, the yarn runs zigzag along the length of the fabric. It requires the preparation of a warp sheet for further use on machine. The most common warp knitted designs or structures are raschel and tricot.
