    • The fluid distribution members according to the present invention preferably comprise three basic components: chemically stiffened, twisted, and curled bulking fibers, high surface area fibers, and thermoplastic binder fibers. Fluid distribution members according to the present invention use a high surface fiber to provide capillary pressure (or suction) to the fluid distribution member. These high surface area fibers are generally small and highly conformable. They provide the substrate with capillary pressure well in excess of the capillary pressure found in the bulk-providing chemically stiffened, twisted, and curled fibers alone. A presently preferred fiber for this high surface application is the eucalyptus family of wood pulp fibers. Eucalyptus provides the capillary pressure usually associated with cellulose fines, but at a large enough length and denier so as to not fill in the voids provided by the chemically stiffened, twisted, and curled fibers and will not easily pass through a forming screen.
    • 根据本发明的流体分配构件优选地包括三个基本组分:化学硬化,扭曲和卷曲的膨松纤维,高表面积纤维和热塑性粘合剂纤维。 根据本发明的流体分配构件使用高表面纤维来向流体分配构件提供毛细管压力(或抽吸)。 这些高表面积纤维通常较小并且高度一致。 它们为基材提供了毛细管压力,超过了大量提供化学硬化,扭曲和卷曲纤维的毛细管压力。 用于该高表面应用的目前优选的纤维是桉木木浆纤维系列。 桉树提供通常与纤维素细粉相关的毛细管压力,但足够大的长度和旦数,以便不填充由化学硬化,扭曲和卷曲的纤维提供的空隙,并且不容易通过成形筛。
