本實驗為中空錠－環錠二階段式紡粗節紗之拉伸物性研究，其實驗結果為芯紗由芯紗羅拉喂入再經由前羅拉送出的成紗拉伸較好，前羅拉線速度/輸出羅拉線進度之比值為1.20及粗節間距越小時，其拉伸物性最好。而增加撚度對拉伸強力則沒有太明顯的影響，但其拉伸伸度則有下降的趨勢。
This thesis was to study the tensile properties of slub yarn sproduced in a hollow spindle-ring spindle two steps spinning system. From the experiments, there were some results as follow: the slub yarns would have the better physical properties, while the core yarn was passed through the core yarn roller, and then the front rollerin spinning. The strength and elongation of the slub yarns would have the best effect, while the ratio of the front roller speed/the delivery roller linearspeed was 1.20 and the pitch between the slubs was 5.5cm. The effect of the yarn twist on its strength was not significant. But, the elongation would decrease with the increase of the yarn twist.
