Abstract:

Equal linear density segment color yarn with the length of transitional segment less than 6 cm was knitted for plain weft knitted fabric. To explore the staggered color segment pattern formation mechanism, the test spinning, knitting and computer simulation were used, and effect of total segment length, color segment length ratio and fabric width yarn length on fabric pattern was investigated. When the fabric width pin number was close to n / 2 times the length of the yarn total segments pin number, high definition diamond pattern formed. When yarn length of fabric width was equal to n/2 times yarn cyclic segment length, n/2 diamonds were formed on fabric width. When yarn length of fabric width was Within the range of n/2±（0～1/8） times yarn cyclic segment length, pure diamond block length, width and hight formulas were deduced.
