The method of converting yarn into fabric by intermeshing loops, which are formed with the help of needles, is known as knitting. There are two basic forms of knitting technology: Weft Knitting and Warp Knitting.
Weft knitting is done with hands, and with machines. Warp knitting is done by machines only. In weft knitting, only a single yarn Is required and the fabric consists of horizontal parallel courses of yarn. On the other hand, warp knitting requires one yarn for every stitch in the row, that is the course, and these yarns make vertical parallel Wales. Warp knitting is resistant to runs, and is commonly used as a lingerie fabric. Weft knitted fabrics can be produced in either tubular or flat form. Weft knitted Fabric is usually highly elastic and highly droppable, which makes it suitable for a wide range of apparel applications. The main advantage of warp knitted fabric is that it is not easy to unravel like weft knitted fabric. However, this fabric is not as elastic as weft knitted fabric. Let us now study in detail the two basic types of knitting:
