空气过滤材料用聚烯烃原纤化纤维的研究

Study of Polyolefin Fibrillating Fiber for Air Filtration Material

文章采用机械开纤法制备了空气过滤材料用聚烯烃原纤化纤维。通过实验确定了制备聚烯烃原纤化纤维最优的加工工艺:热拉伸温度为160℃、一次拉伸比为4、二次拉伸比为2、开纤比为3.0、针密度为75针/cm、热定型温度为220℃。后将原纤化纤维制成了性能良好的高效低阻空气过滤材料,其可应用于个人呼吸防护、空气过滤器、真空吸尘器、汽车空气净化、室内空气净化等诸多领域。

This article adopted mechanical open fibrillating method to prepare the polyolefin fibrillating fiber for air filter material. The optimum conditions for processing were obtained through experiments: hot stretching temperature was 160 ℃, first stretch ratio was 4, secondary stretch ratio was 2, splitting ratio was 3.0, needle density was 75/cm, thermal forming temperature was 220℃. Then the fibrillation fiber was made into air filtration material. With high filtering efficiency and low flow resistance, the material could be applied to personal respirators, air filter, vacuum cleaners, motor air purification, indoor air purification and other fields.
