Airflow Characteristics During the Rotor Spun Composite Yarn Spinning Process
Journal Title: Fibres and Textiles in Eastern Europe - Year 2017, Vol 25, Issue 5
Abstract
Rotor spun composite yarn shows compound performances when combined with staple fibres and filaments, such as excellent hand feeling as well as extreme elasticity and strength. Air characteristics including pressure and speed are critical factors of the rotor spun composite yarn spinning process. In this paper, air flow characteristics in a rotor composite yarn spinning unit are simulated and analysed by Ansys, and then verified by experiments. The results show that with the same spinning conditions, static pressure within the filament guide tube is lowest: -9 kPa and in rotor around -5 kPa. The speed of the airstream accelerates from the transfer channel inlet to the outlet, and reaches the largest value of 386 m/s at the outlet. As the rotor speed increases, the airflow velocity increases; the static pressure decreases; the breaking strength and CV of the composite yarn increase, and the breaking elongation and hairiness decrease according to the experiment results.
