DISCUSSION ON SPINNING TECHNOLOGY FOR SUPERFINE PA STAPLE FIBER

Li Wu (Chemical Fiber Plant of Yueyang General Petrochemical Works)  
The reasons of the formation of defects,split filament and double length fiber during the production of superfine PA staple fiber were analyzed.The influence of spinning process and after processing on the fiber quality was discussed emphatically.The 1.67 dtex×38 mm PA staple fiber with excellent properties could be obtained by selecting the proper chips,appropriately increasing the spin manifold temperature and melt pressure,improving the structure of spinneret and strictly controlling the parameters such as draw ratio,etc .
