    • A method for making a zoned apertured nonwoven web comprises providing an unapertured nonwoven web having a first plurality of weakened locations in a first pattern in a first zone and a second plurality of weakened locations in a second pattern in a second zone. The method comprises applying a substantially cross machine directional tensioning force to the nonwoven web to cause the nonwoven web to rupture at some of the first and second pluralities of weakened locations. The applying step creates a plurality of first apertures in the nonwoven web coincident with the some of the first plurality of weakened locations and a plurality of second apertures in the nonwoven web coincident with the some of the second plurality of weakened locations. The cross machine directional width of the nonwoven web after the applying step is substantially the same in the first zone and the second zone.
    • 一种用于制造分区的有孔非织造纤维网的方法包括提供在第一区域中具有第一图案中的第一多个弱化位置和在第二区域中具有第二图案的第二多个弱化位置的未孔的非织造纤维网。 所述方法包括向所述非织造纤维网施加基本上跨机器的方向张紧力,以使得所述非织造纤维网在所述第一和第二多个弱化位置中的某些处破裂。 所述施加步骤在所述非织造织物中产生与所述第一多个弱化位置中的一些相重合的多个第一孔,并且所述非织造纤维网中的多个第二孔与所述第二多个弱化位置中的一些相重合。 在施加步骤之后的非织造纤维网的横向机器方向宽度在第一区域和第二区域中基本相同。

    • A molded and shaped acoustical insulating vehicle panel having a dry-laid needled fibrous composite composed of a first portion of about 50 to 80 percent meltable binder fibers and about 20 to 50 percent stable fibers and having a second portion of about 20 to 50 percent meltable binder fibers and 50 to 80 percent of staple fibers. The meltable binder fibers are in a molded and resolidified state such that the resolidified binder fibers of the first portion form a substantially continuous, semi-impervious, densified skin integrally associated with and bonded to a surface of the first portion. The molded composite is in such a heat and pressure molded state that the composite has over a predominance of its area a density of from about 12 to 22 lbs./cubic foot (192 to 352 kg/cubic meter) and the panel is sufficiently rigid as to be self-supporting.
    • 一种模制和成形的隔音车辆面板,其具有由第一部分约50至80%的可熔融粘合纤维和约20至50%的稳定纤维组成的干法成网的针刺纤维复合材料,并且具有约20至50%可熔融的第二部分 粘合纤维和50%至80%的短纤维。 可熔融粘合纤维处于模制和再凝固状态,使得第一部分的再固化粘合纤维形成与第一部分的表面整体相关联并结合到其上的基本上连续的,半不渗透的致密表皮。 模制复合材料处于这样的加热和加压模制状态,使得复合材料的面积优于约12至22磅/英尺(192至352千克/立方米)的密度,并且该板具有足够的刚度 作为自我支持。
