Abstract

In this study, experiments were conducted to examine the drafting behavior of non-circular fiber (cross-shaped profiled polyester) to obtain the optimum drafting conditions for spinning polyester/cotton (P/C) blended yarn. The drafting force in the break draft zone was measured and the effects of roller gage, draft ratio and P/C blend ratio on the drafting force were examined. The 20Tex spun yarn was spun with different P/C blend ratios and its quality was evaluated to shed light on the relationship between drafting force and yarn evenness. Experimental results showed that the optimum drafting conditions involved using a roller gage of 62 mm and spinning at a draft ratio of 1.20. In addition, blend yarn of P80/C20 ratio had the best yarn quality.
