    Abstract: A housewrap material for controlling moisture in the walls of a building includes a moisture vapor permeable, water impermeable sheet material having opposite surfaces with a plurality of drainage channels formed in the sheet material for directing the flow of liquid and for imparting to the sheet material a three-dimensional configuration. The sheet material has a crush resistance under a load of about 2.65 psi of at least 50%. In one embodiment, the integral drainage channels are defined by a plurality of generally parallel extending peaks and valleys that allow water to be drained from the wall. The composite nonwoven material has sufficient strength and stiffness to impart significant crush resistance to the composite, so that the integral drainage channels will not be collapsed or destroyed by the subsequent application of siding, stucco, paneling or the like to the building. Preferably, the composite sheet material has a crush resistance of at least 50% when subjected to a pressure of about 2.65 psi. This is particularly advantageous when the composite sheet material is used in conjunction with the application of stucco, although the advantages of the present invention are equally applicable when used in conjunction with a rigid exterior siding material.

    Abstract: The present invention provides a nonwoven fabric that is especially engineered to function as the substrate for a dryer activated fabric softener sheet. The substrate has a basis weight of 0.48 ounces per square yard or less, a thickness of from about 0.16 mm to about 0.38 mm, and comprises a nonwoven web of fibers, wherein at least some of the fibers are hollow. Preferably the fibers have a denier of from 2 to 8. In preferred embodiments of the invention, the hollow fibers have a void area at least 10 percent of the fiber cross-section, and the fibers have a noncircular trilobal cross-section.

    Abstract: An apparatus for manufacturing a transversely aligned web has a spinning device provided with a plurality of nozzles for extruding molten polymer as filaments, and a conveyor on which the filaments spun by the spinning device are piled and traveling in a direction cross to the direction of array of the nozzles. The spinning device is provided with a high-speed fluid blowing unit for blowing a high-speed fluid in a direction parallel with a direction in which the filaments are extruded from the nozzles so as to attenuate the filaments. Further, the apparatus for manufacturing the transversely aligned web has at least one air stream vibrating mechanism for cyclically changing the flowing direction of the high-speed fluid blown from the high-speed fluid blowing unit in a direction cross to the machine direction of the conveyor. The filaments are vibrated in a direction cross to the machine direction of the conveyor, owing to the high-speed fluid by the air stream vibrating unit.
