双色段彩纱针织物图案的形成机制

为探索过渡段在6cm以内的新型双色等线密度段彩纱编织纬编针织物时色段错位循环图案形成机制，通过实验试纺试织并结合计算机方格填色模拟，揭示织物上菱形图案受段彩纱总循环段长、色段段长比及织物幅宽用纱量的影响。当织物幅宽针数接近n/2倍纱线总循环段长针数时，菱形图案的清晰度高；当幅宽用纱量以纱线总循环段长1/2的整数倍增加时，幅宽内菱形个数成1/2整倍数增加。并给出幅宽针数为n/2±（0～1/8）倍纱线总循环段长针数内时纯色菱形块长宽高计算公式。

Pattern mechanism of double color segment-color yarn knitting fabric

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.
