The ring spindle spinning process includes one roving step and one spinning step, the roving step has roving line density of 600-1200 Tex, and the spinning step has spun yarn in the ratio between drafting multiple and English count of 1.03-2.06 time/ English count. Before the roving step, there are drawing step, combing step and carding step to result in semi-finished goods top with linear density of 5.0-7.5 G/m and silver lap line density of 75-120 G/m. The spinning process includes also scutching step with lap ration of 600-1000 G/m. The technological process of the present invention has improved spun yarn quality, less configured fore-spinning apparatus and lowered comprehensive spinning cost. |
