  Abstract:In view of the problems existing in 100% fine cotton spinning C 9.7 tex yarn，such as poor evenness quality，too many knots and low strength of yarn，the practice of technical research in the whole spinning process is described from the aspects of raw material selection，process flow and process control，including:the blowing process can reduce the blow，discharge more impurities and improve the operation；in the carding process，the gauge should be calibrated，the negative pressure should be increased，and the new card clothing machine should be optimized；the drawing ratio should be allocated reasonably in the drawing and roving processes；pressure bar spacers should be use in the spinning process，the cots should be treated with UV light，twist should be increased appropriately in the spinning process；low speed，low tension technology configuration are adopted in winding process.It is pointed out that raw material is the foundation，cotton carding is the key，the drawing process adopts the principle of forward drafting process and reasonable drafting multiple distribution，and the spinning process should select the textile accessories，improve the yarn evenness，reduce the knots and increase the strength，and the yarn quality can be significantly improved and reached the excellent level of GB/T 398-2018.
Key Words:fine cotton；compact spun yarn；micronaire value；forward draft；pressure bar spacer；cot；surface treatment；evenness；yarn quality
