To evaluate the mechanical influence of grooved collector geometry and drafting process parameters on friction forces and yarn quality in a multi-principle ring spinning system.
Developed a mathematical model of the front gathering zone to analyze the effects of collector inlet width, outlet width, and path length on frictional forces.
Applied response surface methodology to model and optimize break draft ratios, front roller gauges, and back roller gauges for spinning 18.4 tex yarns.
Numerical analysis showed collector outlet width and path length significantly determine friction forces, whereas inlet width variation exhibits minimal effect.
Experimental spinning confirmed outlet width significantly affects yarn tenacity and hairiness without substantially impacting yarn evenness or imperfections.
Response surface optimization identified ideal parameters (1.2 break draft ratio, 32.5 mm back roller gauge, 17.5 mm front roller gauge) that achieved 10.57% yarn unevenness compared to the predicted 10.71%, matching the Uster Statistics 2018 5% benchmark.
