Abstract
Influence and application effect of slighter pressure,heavier weight per unit and higher speed production technology on R 14.8 tex hard twist yarn were discussed.Drafting control property of slighter pressure production technology was analyzed.Taking spin R 14.8 rex hard twist yarn as example,the selection of top pin,middle rubber-covered roll,interior pattern apron and front & back rubber-covered roll were contrasted and tested.The technology parameters were optimized like roving weight per unit,roving twist factor,draft multiple in back zone,roller center distance,nip gauge and cradle pressure.The results show that R 14.8 rex hard twist yarn quality is improved obviously,equipment loading is decreased,the consumption of spun yarn related accessories and textile appliance & accessories are decreased,power consumption per ton yarn is obviously decreased,the yield is increased and labor consumption is reduced after adoptiog slighter pressure production technology.It is considered that slighter pressure production technology is the advantage spinning technology that can realize high er-efficient and lower-consumption production.关键词
