摘要
为开发非织造布辊用基布材料,以高强度聚丙烯(PP)纤维和聚酰亚胺(PI)纤维为原料,通过干法非织造布工艺制得样品。以纤维比例、针刺密度、针刺深度为因素,样品的面密度、厚度、拉伸强力、撕破强力、顶破强力、吸水倍率、孔径为指标,设计三因素三水平正交试验,探究影响非织造布辊用基布材料性能的主要因素。结果显示:影响产品撕破强力、顶破强力、吸液性、透气性的因素依次为针刺深度、纤维比例、针刺密度;影响产品拉伸强力的因素依次为纤维比例、针刺深度、针刺密度。最优工艺参数为高强度聚丙烯/聚酰亚胺(80/20),针刺密度800刺/cm2,针刺深度5 mm。
In order to develop the base fabric material for nonwoven roller,samples were prepared by dry nonwoven process with high strength polypropylene(PP)fibers and polyimide(PI)fibers as raw materials.With fiber proportion,acupuncture density and acupuncture depth taken as factors,fabric density,thickness,tensile strength,breaking strength,bursting strength,water absorption ratio and pore diameter of samples as indexes,three-factors and three-levels orthogonal test was designed to explore the main factors affecting the property of base fabric material for nonwoven roller.The results show that the factors influencing the tensile strength,bursting strength,liquid absorption and air permeability of the product were in the order of acupuncture depth,fiber proportion and acupuncture density,and that the factors influencing the tensile strength of the product were in the order of fiber proportion,acupuncture depth and acupuncture density.The optimized process parameters were determined as high strength polypropylene/polyimide(80/20),acupuncture density of 800 needles/cm2 and acupuncture depth of 5 mm.
