    摘要: A topographical support member and a method of forming a topographical support member for use in producing nonwoven fabrics with raised portions, especially intaglio and slub type portions. The topographical support member comprises a body having a top surface including a first micro-sized topographical pattern and a pattern of apertures extending through the body. At least one macro-sized region recessed below the top surface is provided. The micro-sized pattern produces a background portion of the fabric and the macro-sized recessed regions produce the raised portions of the fabric. Multiple levels may be provided in the macro-sized region to produce multiple level raised portions.

    摘要: A topographical support member and method of forming a topographical support member for use in producing nonwoven fabrics, especially tricot-like nonwoven fabrics. The topographical support member includes a body having a top surface comprising a pattern of a plurality of peaks and valleys and a plurality of apertures. The apertures have a conical top portion that is surrounded by a cluster of the peaks and valleys. The center line to center line spacing of adjacent apertures is less than the major diameter of the conical top portion of the apertures. The topographical support member is formed by focusing a laser beam so that the focal point is below the top surface of a starting workpiece and drilling with the laser beam the predetermined pattern of tapered apertures. The pattern of tapered apertures forms the cluster of peaks and valleys surrounding each aperture on the top surface of the resulting support member.

    摘要: An apertured film for use as a topsheet in absorbent products wherein the film is apertured and includes a plurality of micro-holes and a plurality of large-sized holes. A method of forming the film is disclosed, as well as an absorbent product incorporating the apertured film as a topsheet. The method includes the step of supporting the starting film on a backing member which has recessed zones into which the film may be deformed. In the preferred embodiment, fluid in the form of columnar streams is directed from at least two sets of orifices against the upper surface of the starting film. The orifices of the first set have a diameter greater than 10 mils, and the orifices of the second set have a diameter less than or equal to 10 mils. The fluid is discharged from the smaller orifices at a pressure of at least 500 psig, and the fluid is discharged from the larger orifices at a pressure less than 500 psig.

    摘要: Nonwoven fabrics having a fibrous background portion in one plane thereof and raised fibrous portions in another plane thereof. There may be two types of raised portions. In one type, the basis weight of the raised portion is substantially the same as the basis weight of the background portion. In another type of raised portion, the basis weight is greater than the basis weight of the background portion. The raised portions are joined to the background portion by a fibrous transition region.
