Abstract:In order to reasonably control the number of neps in spinning production and improve yarn quality，the causes of neps in cotton picking，cotton processing and spinning production are analyzed，as well as the influence of raw cotton maturity，defects，linear density and moisture regain on the number of neps.The influence of opening process，specification of carding elements and card clothing of carding machine，cleaning and suction of carding machine，combing process and site management on sliver neps is analyzed deeply，and the measures to reduce neps are put forward accordingly.Practice shows that it is necessary to select raw cotton，optimize process，select accessories，maintain equipments and manage operation to control neps and improve yarn quality，so as to produce less neps and eliminate more nep in production process.We should control the sliver neps within the range of quality index in carding process，and do well in light weight，reasonable drafting，optimizing gauge，reducing speed，low merging，frequent maintenance，paying attention to cleaning and maintenance in combing process.
Key Words:cotton picking；raw cotton characteristics；spinning process；nep；combing；gauge；speed；carding element；card clothing；yarn quality
