Abstract:In view of the problem of C 14.58 tex yarn with a lot of neps，the practice of technical research in the whole process of spinning is described from the aspect of process control，that is， improving the operation rate of blowing process，excluding impurities as much as possible，reducing the speed of the fan and reducing the blow；optimizing cotton card clothing，and increasing negative pressure；reasonable configuration of the drafting multiple in drawing；in the spinning process，extended top cradle is adopted，and its front impact power，roving twist coefficient and the gauge of the yarn jaws are adjusted.It is pointed out that after technical breakthrough，the number of neps in per kilometer of C 14.58 tex yarn has dropped from about 400 to less than 200，and the evennness，fine ends and slubs have been improved obviously，the break of the post-spinning process has been reduced，the efficiency has been increased，and the fabric style is good.
Key Words:nep；operation rate；negative pressure；back stationary flat；drafting multiple；extended top cradle
