Abstract:

Based on the numerical control ring spinning frame with a coupling drafting system, a kind of multiple-component rainbow segment-color yarn were presented. By analyzing the relationship of fabric width, colored yarn period, and segment length, the theoretical models of lengthways, transverse, crossed and punctate pattern were designed. The mechanism of structure design of weft knitting by using the rainbow segment-color yarn was studied. A simulation software for designing weft knitting pattern were developed by using Java. The simulation software includes file operation, forward deducing form, backward deducing form and help. The forward deducing form means that the fabric pattern of weft knitting can be deduced from segment length, fabric width, loop length, etc.

Key words: numerical control ring spinning frame, segment color yarn, fabric pattern, simulation software
