Application property of spinning pressure bar top pin was discussed.Nipper gauge,draft multiple in back zone,roving twist factor and roving weight per unit were tested and optimized according to the problems in applying spinning pressure bar top pin.The result shows that finish yarn evenness could be improved and frequent yarn default could be reduced by using spinning pressure bar top pin.Roving weight per unit could be increased and supply capacity of before spinning process could be increased as well.Relative processing parameter should be selected rationally in application to resolve problems such as draft and breakages et al and make full use of pressure bar top pin function.
