结合32头环吹直纺的设备特点,对32头环吹直纺技术进行了探讨。结果表明:32头环吹直纺技术节能高效,技术先进。在32头环吹直纺生产中,将纺丝温度及组件压力适当提高,采用适合环吹生产的喷丝板及冷却上油工艺,制定合理的拉伸卷绕工艺,有利于多孔超细旦纤维的生产。
Combined with the characteristics of the 32 ring-blow spinning equipment, 32 ring-blow spinning techniques were discussed. The results show that: 32 ring blown spinning technology is energy efficient and advanced technology. In the 32 ring blown direct spinning production, the spinning temperature and the component pressure are appropriately increased. The spinneret suitable for the ring blowing production and the cooling oiling process are used to formulate a reasonable stretch winding process, which is favorable for the production of the porous ultrafine denier Fiber production.
