43—HIGH-SPEED OPEN-END ROTOR-SPINNING

Abstract

High-speed open-end rotor-spinning is discussed in relation to the properties of yams spun in the speed range from 30,000 to 100,000 rev/min. The design of the rotor and its modified driving unit is described in detail. The properties of the yarns with respect to strength and strength variation, extension at break, and short-term yarn evenness are discussed.
