Characteristics of Novel Triplet Spun Yarns Made from Fibers of Differing Fineness

Abstract

In order to reduce the hairiness of ring spun yarns and to develop novel multilayered spun yarns, we investigated the properties of triplet spun yarns made from the same size of three rovings with different fiber fineness using an experimental ring spinning frame. The results were: (1) different fiber fineness triplet spun yarn, a new yarn made by combination staple fibers of three different fineness into one twisting process; (2) although triplet spun yarn had a side-by-side structure in the cross-section, the central angle made by the assembly of finer fibers was smaller than that of coarser fibers; and (3) in comparison with single yarn, triplet spun yarn had less hairiness and greater strength because of the lower spinning tension of each strand and the twist propagation in each strand.
