Abstract:In order to improve the quality of semi-products，cotton yarn and fabric，the carded sliver，combed sliver，cotton yarn and fabric quality under different passages of slivers and number of combined slivers of the drawing frame with auto-levelling system and the drawing frame without auto-levelling system are compared by test,and the different effects on yarn defects are analyzed and the solutions are proposed.It is pointed out that the development of spinning equipment and spinning accessories has promoted the development of online spinning control technology，which provides guidance for the control of cotton yarn defects in post-process,the spinning mill needs to determine the drawing process according to the actual production.There is a close relationship between uneven dyeing and stripiness and the passages of slivers and the number of combined slivers of drawing frame.No matter whether the drawing frame has auto-levelling system or not，using process with two passages of six combined slivers or eight combined slivers is conducive to reducing fine yarn defects and controlling uneven dyeing and stripiness of fabric.Under the good condition of equipment，the optimization of the passages of slivers and the number of combined slivers is the fundamental to stabilize the quality of cotton yarn and fabric in post-process.
Key Words:drawing frame；combining number；yarn defect；uneven dyeing；stripiness；carded sliver；combed sliver；cotton yarn；fabric；weight unevenness；evenness
