Worsted cashmere top and yarns blended with low or high curvature superfine merino wool

In this replicated experiment, we investigated the impact of cashmere on blends with superfine wools on the quality of tops, rovings, and worsted spun yarns. We also investigated the relative performance of soft, low crimp/low fiber curvature superfine wool when compared with cashmere and also I when compared with traditional high crimp/high fiber curvature superfine wool in pure blended yams. The results indicate both the cashmere blend ratio and fiber curvature/crimp of wool affected processing requirements and the attributes of worsted pure and blended tops, rovings, and yarns. Adding wool to cashmere improved the processing of cashmere roving and reduced faults. Mean fiber curvature was a good predictor of yarn hairiness and yarn tenacity.
