摘　　要：为探讨制备工艺参数对熔喷非织造布纤网结构的影响,按计量泵频率、网帘频率和接收距离的不同组合制备了13种聚丙烯熔喷非织造布,借助基平面网对纤网细观结构进行表征以简化研究。结果表明:随着计量泵频率的提高,纤维直径及其变异系数均增大,基平面网特征长度和层数均下降;随着网帘频率的提高,基平面网特征长度和层数均下降,同时取向度提高;随着接收距离的增大,纤维直径及其变异系数均增大,基平面网的特征长度减小但其层数增加,同时取向度下降。To study the infuence of process parameters on the fber web structure of meltblown nonwovens, thirteen melt blown polypropylene nonwovens were produced by combining metering pump frequency, mesh belt frequency and the distance from die to collector in diferent ways. The fber web meso structure was characterized by using basal plane so as to simplify the study. The results show that with the increase of the metering pump frequency, both the fber diameter and its variation coefcient rise, but the characteristic length of basal plane and the number of basal planes show a downward trend. When the mesh belt frequency increases, the characteristic length of basal plane and the number of basal planes decrease, whereas the degree of fber orientation rises. As the distance from die to collector gets larger, the fber diameter and its variation coefficient as well as the number of basal planes tend to increase, meanwhile the characteristic length of basal plane and the degree of fber orientation decline.
