S. Ulku et al., EFFECTS OF OPENING ROLLER SPEED ON THE FIBER AND YARN PROPERTIES IN OPEN-END FRICTION SPINNING, Textile research journal, 65(10), 1995, pp. 557-563
The opening roller system for fiber separation in an open end spinning
process is known to cause considerable fiber breakage. We have invest
igated fiber breakage at different opening roller speeds and the relat
ionship between breakage and the properties of friction spun yarns mad
e from cotton, polyester, viscose, and acrylic fibers. A high level of
fiber damage caused by the opening rollers occurs at high speeds. The
level of damage differs from one sort of material to another. There i
s a great deterioration in properties when yarns are processed at high
opening roller speeds.
