摘要
生产黏胶纤维的纺丝原液中存在的大量杂质粒子会堵塞喷丝孔,从而降低黏胶成品的质量,且会缩短纺丝组件的使用周期,因此需要通过过滤工序来去除原液中的杂质微粒,这是保证和提高黏胶纤维的质量和特性的前提,而过滤介质是过滤工序的核心。金属纤维烧结毡是一种具有不同孔径梯度的过滤介质,具有过滤精度高、纳污量高、强度高、易加工、耐高温、过滤速率高、寿命长、反洗效果好等优势,通过深层过滤机制,能够有效地去除黏胶原液中的杂质粒子,保证黏胶纤维的质量和特性。
The spinneret may be blocked by a large quantity of impurity particles in the viscose spinning solution, and that may decrease the quality of viscose fiber and shorten the lifetime of spinning pack.Therefore, filtration process is needed to remove the impurity particles, such process is the essential prerequisite of quality insurance. Furthermore, filtration medium is the key point of filtration process.Sintered metal fiber media is one kind of filtration medium which has pore diameter grades formed by layers of different pore size can achieve higher filtration accuracy and larger dirt capacity. It is not only resistant to corrosion and high temperature, but also has high strength and long lifespan. Besides, metal fiber felt is easy to process and has high filtration velocity, which can efficiently remove impurity particles via deep filtration mechanism.
