Study on the Rotor Spinning Processing of Spun Silk/CashmereBlended Yarn

This paper studies roto spinning blended yarn producedof spun silk and cashmere. Nine samples were spun, from threedifferent opening rollers and different navels.According to theUster test results of yarn quality prioerties, optimum selection isdane by using analysis method of combining fuzzy decision-makingand fuzzy pattern classification.Expermental plan is designedbased on universal rotated experitmental design, and the method ofconfined optimization is used to optimize the speed of openingtaller, the speed of rotor and twist factor, according to the resultsof yarn quality test by Uster.
