Influencing parameters of rotor and wrapping fiber depends on
No. of wrapping fiber depends on: 1. The position at which the fibers laid on the rotor wall. 2. The length of the binding-in- zone. 3. The ratio of fiber length to the rotor circumference. 4. The false twist level. 5. The rotor speed. 6. Fiber fineness. Influencing parameters of rotor • Rotor is the main spinning element of the rotor spinning machine. Yarn quality, yarn character, working performance, productivity, costs etc. all depend chiefly on rotor. • Influencing parameters of rotor: 1.The rotor form 2.The groove 3.The diameter 4.The rotational speed 5.The rotor bearing 6.Co-efficient of friction between the fiber and rotor wall. 7.The airflow inside the rotor 8.Liability to fouling.
