Mechanism and Confirmation in Compact Spinning with Suction Groove

Compact spinning eliminated the harmful effects of spinning triangle, as the edge fibers are incorporated into the yarn due to the elimination of the spinning triangle. The compact yarns possess less hairiness, higher breaking strength and breaking elongation compared with the conventional ring-spun yarns. In this article, we study the mechanism of compact spinning with suction groove and analyze the compact action in twisting fiber strip. Some quality parameters of wool compact spinning with suction groove are compared with those of wool conventional ring-spun yarns. The changes of hairiness are analyzed in the different spinning conditions. This provides related data for improving compact spinning system with suction groove.
