Geometrical Modelling of Plain Weft Knitted Fabrics

In order to produce the fabric with maximum cover factor with the minimum weight, it’s only possible when GH is the distance between the loops in a horizontal direction and KJ is the correct length between the loops in a longitudinal direction. In this article Dr Vojislav explains geometrical pattern of knitted fabrics.

Textile Fabric Types by Fiber Sources

Generally, a set number of yarns are used for the formation of fabrics. Also, a number of techniques are used for producing fabrics such as weaving, knitting, and felting. The type of fabrics varies by the fibers, the fabric formation techniques, machinery used for producing them, and finishing techniques. Fabrics also made differently based on the end-usage.

Yarn guide in Knitted fabric formation

In warp knitting a yarn guide wraps the yarn around the needle hook, thus forming a loop. However, to form a fabric, the yarn guide must wrap the yarn around a different needle during the next course. The yarn guides, therefore, must be displaced laterally during knitting. Different warp knitted structures are produced by varying the magnitude of their lateral displacement. Therefore warp knitted structures can be described by noting the guide bar displacement.

Knitting Lapping Diagrams

With the exception of the very simplest structures, it is too time consuming to represent warp knitted fabric using stitch or loop diagrams. For this reason two methods of fabric representation are commonly used a. Lapping diagrams, b. Numerical representation.

Warp Knitting

Warp knitting is the sequential formation and interlinking of loops in an axial direction on a lateral array of needles with at least one separate thread being supplied to each needle. The loops are joined together in a width-wise direction by moving the threads back and forth between adjacent needles.
