碩士 === 國立臺灣科技大學 === 高分子系 === 95 === For the optimum drafting conditions of the Bamboo Charcoal Fiber yarn (BCF yarn) spinning, the application of the drafting force has to be studied. In this work, we precede the experiment of the drafting force based on the BCF roving to investigate the influence of the roller gauge, and draft ratio on the drafting force. We understand the drafting force of the BCF roving follow the same trend as for the regular Polyester and Cotton blend roving. However, the character of the drafting force reveals some difference between them. To correlate the CV% of the drafting force and the yarn properties, Besides, we evaluated the yarn quality with CV%、IPI(Imperfection Indicator) and investigate the best yarn quality in conjunction with the drafting ratio. The results show that we can obtain the best BCF yarn quality based on the drafting conditions of 1.3 break draft ratio and 54mm back roller gauge in conjunction with the roving of T70/C30 and 1.2 break draft ratio and 54mm back roller gauge in conjunction with the roving of R40/C60.
