摘　　要：非织造材料中包含大量细小立体弯曲通道,广泛应用于口罩的过滤层。结构决定材料的性能,为建立非织造织物的细观三维结构,通过全自动显微镜采集的50图层序列图像,经自行研发的软件得到非织造布的三维点云,在GeomagicStudio软件中建立了织物试样的三维模型。非织造布的三维重建图像结果显示,三维建模的方法能真实地模拟仿真纤维在非织造布中的三维堆砌结构。Nonwoven materials contained a large number of micro three-dimensional curved channels,which was widely used in the filter layer of masks.Structure determined the performance of the material.In order to establish the mesoscopic three-dimensional structure of the nonwoven fabric,the three-dimensional point clouds of the nonwoven fabric were obtained through sequential 50-layer images collected by the automatic microscope and the software developed by research group.The three-dimensional model of the fabric was visualized in Geomagic Studio software.Three-dimensional reconstructed images of nonwovens showed that the 3 D modeling method could simulate the three-dimensional packing structure of fibers in nonwoven fabrics.
