Abstract:In order to realize the spinning of high quality yarn with lower grade cotton，medium cotton and long-staple cotton combed noil are used as raw materials to spin combed yarn.According to the physical indexes of raw materials，the spinning process is developed，and the main technological parameters and technical measures of the processes of cleaning，carding，drawing，roving and spinning are described in detail.By comparison of test spinning，it is found that 18.2 tex carded yarn is spun with 25% and 35% long-staple cotton combed noil and 8% recycled medium cotton，and 14.6 tex carded yarn is spun with 10% long-staple cotton combed noil and 8% recycled medium cotton.The yarn quality index is in GB/T 398—2018 second class yarn index.It is pointed out that choosing appropriate process route is very important when using long-staple cotton combed noil spinning yarn.The key of using high proportion of combed noil is to reduce fiber damage in carding process，control short fiber movement in drawing and roving process，improve the opening and impurity removal effect of medium cotton fiber in carding  process，improve the mixing effect of sliver and reduce accidental drafting in roving process，adopt compact spinning technology in spinning process to improve the degree of fiber agglomeration，and give full play to the function of accessories and parts.
