Abstract
Application technologies of Rieter ring spinning system were discussed. According to features of Rieter ring spinning system,gauges and speeds in opening and picking process were optimized,neps increase rate in feed web and short fiber content were reduced. In carding process,a series of measures were adopted to increase fiber transfer and reduce fiber injury such as optimization each gauges, reducing lick-in speed and increase cylinder lick-in linear speed ra tio properly. In drawing processing configuration, fiber straightness, draft distribution and roller gauge were set rationally. In roving process,spinning tension was controlled well, processing parameter was set rationally to improve roving inner quality. In spinning process, knitting yarn processing of larger roving twist factor & larger spinning back zone gauge and less nip gauge & less spinning back zone draft was adopted. Then distance between front rubber-covered roll and medium iron roller was optimized, finally quality index of C 14. 6 tex yarn can reach 2007 Uster Statistics 5% level.关键词
