Abstract:In order to reduce yarn neps and improve yarn quality，the concept of testing neps with USTER AFIS single fiber tester and USTER TESTER evenness tester and the application are introduced.The correlation between the number of sliver neps and combed sliver neps and yarn neps is tested and analyzed.The process measures of optimizing total teeth number and central angle of tooth surface of combing cylinder card clothing，top comb，cotton feeding mode，speed，weight per unit of lap and combing process to reduce yarn neps are discussesd.It is pointed out that there is no linear correlation between the nep number measured by Uster single fiber tester and sliver test tester，and there is no necessary correlation between the nep number(neps/g) in sliver and combed sliver and yarn neps(yarn neps/km).There is little correlation between noil rate and nep number of carding sliver，but it is closely related to staple content of combed sliver and the the common yarn defect IPI value.The key to controlling yarn knots lies in combing quality，and the core is combing cylinder card clothing，so combing accessories with high cost performance ratio should be selected to reduce yarn neps.When the forward feeding process is implemented，only by using big tooth surface combing cylinder with the 111° central angle，configuring feeding length with 4.7 mm，appropriately increasing speed and weight per unit of lap，choosing top comb with good quality tooth and high combing efficiency，reducing and stabilizing combing zone gauge of combed cylinder，doing good job in process adjustment，state inspection and daily cleaning of combing accessories，and optimizing raw cotton，can the high efficiency，high yield，high quality and low consumption of comber be realized.
Key Words:combing；neps；cylinder；total carding point；central angle of tooth surface；top comb；forward cotton feeding；combing area gauge
