Comparative Analysis of Cotton Yarn Properties Spun on Pneumatic Compact Spinning Systems

The article presents a comparative analysis of the properties of cotton yarn spun on three pneumatic compact spinning systems Rieter (R) K-44, Suessen (R) Elite and Toyota (R) RX-240. Combed compact cotton yarn with a linear density of 10 tex was spun on these compact spinning systems using medium staple cotton. The roving processed had the same technological and kinematical parameters. The quality parameters such as mass irregularity, the imperfection index (IPI), hairiness and tensile behavior of the compact spun yarns were tested and analysed. The results revealed that K-44 compact spun yarn had less mass variation, a low IPI value, less hairiness and high tensile properties compared to the other compact spinning systems employed in the present work.
