Abstract:

Producing yarn from natural fibres without creating irregularities in structure or having fibres protruding from the surface, remains the goal of spinners. This is a shortcoming, as structural irregularities such as hairiness, unevenness affect subsequent fabric manufacturing processes and the aesthetics of the final fabric. Sustainability of a noble false twister device and its influence on physical properties of staple cotton yarn has been studied in this research. A false twister has been installed in the ring frame to modify the yarn path of conventional ring spinning system to improve physico-mechanical characteristics of cotton ring spun yarn. This work therefore focused on investigating the effects of varying the spindle speed of a ring spinning frame on the structure of yarn (i.e., its surface regularity and hairiness), its strength with a view to optimizing the spindle speed with this novel false twister. For this, yarns with counts of 15, 20, 25, and 30 tex were produced from 785 tex roving at five different spindle speeds ranging from 6,500 to 8,000 rpm with an interval of 2,000 rpm. All other parameters were kept constant, including the draft for a particular count, the type and weight of the traveller, and the diameter of the ring. Yarn strength, irregularity (u %), coefficient of variation (CV %), actual count (Tex) and actual twist (T/10cm) has been investigated, analysed by YG173A yarn Hairiness Tester, YG133B/M Evenness Tester 4 and YG (B) 021DX tensile strength tester. The results from numerical simulations of modifies spinning system indicate that, physicomechanical characteristics of cotton ring spun yarn has been improved in a considerable value. Thus points the speeding up of productivity of the yarn manufacturing.
