The invention relates to a composite fiber foamed non-woven fabric as well as a preparation method and application thereof. The composite fiber foamed non-woven fabric comprises a composite fiber material and hollow polymer microspheres filled in pores of the composite fiber material, the weight ratio of the composite fiber material to the hollow polymer microspheres is 1: (0.01-0.3). According to the composite fiber foaming non-woven fabric, the pores of the composite fiber material are filled with the hollow polymer microspheres, so that the energy absorption area can be increased while supporting is formed among fibers, and the mechanical strength and acoustic sound absorption performance of a product are greatly improved.

    本发明涉及一种复合纤维发泡无纺布及其制备方法和应用,该复合纤维发泡无纺布包括复合纤维材料和填充在所述复合纤维材料孔隙内的空心聚合物微球;所述复合纤维材料与所述空心聚合物微球的重量比为1:0.01~0.3。本发明的复合纤维发泡无纺布,在复合纤维材料孔隙内填充空心聚合物微球,能够在纤维之间形成支撑的同时增加吸能面积,大幅提升产品的力学强度以及声学吸音性能。
