3-D Modelling of Basic Weft-Knitted Fabric Structures

Abstract

Based on the structural analysis of sample knitted fabrics and the knit geometric theory, we have built an algorithm that can make three-dimensional structure models for weft knitted fabrics such as welt stitches, tuck stitches, cross stitches, rib stitches and purl stitches. In order to reduce computational complexity, we have set the anchoring point on the diametral plane of yarn in the knitting chart. Drawing from the beginning knitting point to the finished knitting point, a smooth knit curve model can be obtained with the cardinal spline curve. Using this algorithm, we have developed the weft knit three-dimensional structure modeling software that can display the three-dimensional model of knitted fabrics including welt stitches; tuck stitches, cross stitches, rib stitches and purl stitches.Our work confirms 3-D modeling of three foundation knits of weft knit (plain stitches, purl stitches, rib stitches), tuck stitches, welt stitches and cross stitches with a commercially available PC. This software can be used by someone with no understanding of knitting to gain an understanding of the knitting process, and determine the structure of a knitted fabric product.
