Abstract:

In order to simply predict the pattern shape of flat-knitted fabric with a given section dyed yarn, the characteristics of segment color distribution and the knitting way of the fabric were analyzed. The distribution regularity of segment color in the fabric was defined and could be simulated using the triangle wave. A simulation program for pattern of the flat knitted fabric with given section dyed yarn was deveolped by using MatLab program. The predicted results are in good agreement with the fabric samples. The result showed that changeable patterns can be formed as the characteristics of segment color distribution combined with the knitting way of the fabric. The apttern shape is closely related to the length of color segment cycle and yarn used in a course of the fabric. The prediction of pattern can be easily realized by the MatLab program.  The required pattern can be obtained by changing the number of knitting needles and by selecting or designing the section dyed yarn.

Key words: section dyed yarn, flat-knitted fabric, pattern prediction, segment color distribution regularity
