A Novel Compact Spinning with Lattice Apron Achieved through Airflow Simulations

Abstract

Compact spinning with a lattice apron is commonly used in commercial yarn spinning despite the high energy consumption due to high negative pressure generated during operation. In the current study, a numerical and experimental approach is used to study the impact of airflow behavior on yarn properties. Three-dimensional (3-D) printed guiding devices were used to control the airflow mechanism and negative pressure. Airflow analysis showed a significant decrease in the negative pressure and the rise in the total airflow velocity and streamlines distribution. This phenomenon eliminated the spinning triangle thus enhancing the spun yarn qualities and energy efficiency. The novel design is thus commended for further improvement and commercialization.
