Pneumatic splicing was examined for various yarns spun from different fibers on different spinning systems. The retention properties of the spliced yarns compared to normal yarn are discussed; the results indicate that wet splicing gives better property retention than dry splicing. Retention of yarn properties in decreasing order was for yarns spun from polyester, polyester-rich blends, viscose, cotton, and wool, respectively. Coarse yarn, particularly that spun on a ring spinning system, contributes the most to better spliced yarn properties.
