Fiber Migration in Staple Yarns
1969
Gupta, B. S. (Bhupender S.) | Hamby, Dame S.
The effects of spinning tension and spindle speed in fiber migration are studied and discussed. By using a novel experimental technique, staple yarns were prepared at several widely different levels of spindle speed, while holding the tension constant, and at several widely different levels of spinning tension, while holding the speed constant. By using these samples, the effect of spindle speed and spinning tension on the migratory behavior of fibers in staple yarns was studied. It was found that the migration behavior of fibers depends to a large extent upon their squared mean radial position in the yarn cross section. The two processing variables considered are shown to have a significant influence on the rate of fiber migration. The results are analyzed in terms of the buckling strains in a migrating fiber.
