摘要
介绍了采用熔体直纺生产101 dtex/114 f细旦多孔扁平涤纶POY的可纺性研究。试验表明:生产101 dtex/114 f细旦多孔扁平涤纶POY时,熔体输送温度设定在278~282℃,适当提高纺丝温度,选用适宜的纺速、集束高度及环吹冷却条件,选择合适的工艺参数可以产出满足生产要求的多孔细旦扁平涤纶预取向丝。
The spinnability of 101 dtex/114 f fine denier porous flat polyester POY produced by melt direct spinning is introduced.The experimental results show that:when producing 101 dtex/114 f fine denier flat polyester POY,the melt conveying temperature is set at 278~282℃,the spinning temperature is properly raised,the spinning speed,bundle height and cooling conditions are selected,and the suitable process parameters are selected,which can produce the pre oriented fine denier polyester pre oriented yarn.
