| Different kinds of yarns have different structures and performance because of different spinning type. A rotor-spun composite yarn spinning system was developed which produces different kinds of composite yarns containing filament on a modified rotor spinning frame. a supply bobbin by means of a tension device Sirofil yarns were produced by modified ring spinning machine. And longitudinal views, abrasion resistance, hairiness and breaking strength of, separately, rotor-spun composite yarn and Sirofil yarns were tested and analyzed. The conclusion that compared with sirofil, rotor-spun composite yarn had a smoother surface, less hairiness, higher abrasion resistance, lower breaking strength and better evenness was achieved. |
