摘要:

为纺制恒线密度双色变换段彩纱,找出双色变换段彩纱共混段长度、强度的影响因素及规律,采用双通道环锭纺技术纺制双色变换段彩纱。分析了双色变换段彩纱共混段的成纱机制。同时,借助纱线连续采集装置采集连续纱线图片,结合人工识别,测出双色变换段彩纱共混段长度。研究了后区牵伸倍数和粗纱喂入提前量对共混段长度及强力的影响规律。结果表明:共混段长度随着粗纱喂入提前量的增大而增大,随着后区牵伸的增大略有减小;共混段强度随着粗纱喂入提前量增大而增大,本文实验条件下,后区牵伸倍数从1.1增大至2.3,共混段强度最大值出现在后区牵伸倍数为1.7时。

关键词: 双色变换段彩纱, 共混段, 牵伸分配, 粗纱喂入提前量

Abstract:

In order to spin the two-color transformation segment color yarn with constant linear density, and find out the influencing factors of the length and strength of the blend fragment, the yarns were spun by a double-channel ring spining machine with an improved compact device. Meanwhile, the length was measured by artificial recognition based on the image acquisition device. The forming mechanism of the blend fragment was analyzed. The intluence of the break draft and the roving feeding advance on the length and strength of the blend fragment were investigated. The results show that the mean length of the blend fragments increases with the increase of roving feeding advance, and decreases with the increase of break draft; and the yarn breaking tenacity also increases with the increase of roving feeding advance. When the break draft is 1.7, the yarn has the max breaking tenacity.

Key words: two-color transformation segment color yarn, blend fragment, draft configuration, roving feeding advance
