THE IMPACT OF NEW SPINNING TECHNOLOGIES ON THE EGYPTIAN COTTONS

Abstract The yarns spun on the compact spinning system are characterized by higher tenacity, higher elongation at break, smaller mass irregularity measured at short segments, and significantly lower hairiness in comparison with yarns spun on the conventional ring spinning frame. For the Long Staple Egyptian cotton varieties, the breaking force or single yarn strength of the compact yarn (with a nominal linear density of 15tex spun from Long-Staple cottons) was 17.63% higher than the conventional ring spun yarn, while for the Extra-fine carded yarns spun from Extra-Long Staple varieties (it was around 7.0%). This means that, the compact spinning system is more useful for Long Staple cottons and coarse and medium counts than for the Extra Long Staple cottons and finer counts.
