ABSTRACT

In warp knitting machine, unlike weft knitting machine, yarn comes from warp beams. Individual yarns are wrapped on beam. Each needle is fed individually, and sheet of knitted fabric is formed, which is then wound on take-down roller. Warp yarn passes through guides. Guide is a thin metal plate having a hole at one end through which warp yarn passes. Guides are placed on a lead piece of 1 inch. For fabric formation on warp knitting machine, there is need to feed the yarn to the individual needle as well as to connect the adjacent wales, and the guides of a guide bar execute a compound lapping movement. There are two main factors of warp knitted structure representation: the first one is the way each guide bar is threaded, and the second one is the lapping movement of each guide bar. Lapping diagram is used to show actual guide bar movement around needles.
