  • Patent number: 6623469
    Abstract: The invention is a refastenable mechanical fastening system, made of free formed prongs joined to a substrate. The prongs taper and are nonperpendicularly oriented relative to the plane of the substrate. Each prong has an engaging means projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate, stretching the liquid material in a direction parallel to the plane of the substrate and severing the stretched material to form the distal end and engaging means of the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent garment, specifically a diaper, is also disclosed.
    Type: Grant

  • Patent number: 6136405
    Abstract: A process for forming a sheet material having a fibrous surface and the sheet material produced thereby; the fibers are produced by deposition of a heated, thermally sensitive material on to a substrate, which is transported at a velocity approximately equal to the velocity of the material being deposited, by manipulating the fiber density and denier, the sheet material can be made to be either softer or rougher to the touch.

  • Patent number: 6025535
    Abstract: The present invention provides a fluid previous fibrous, preferably nonwoven, web having a first surface and a second surface. The web comprises a hydrophilic nonwoven web comprising a plurality of individual, preferably whitened, brightened, and/or opacified, fibers associated with one another. The web includes a plurality of surface energy gradients defined by the boundaries of discontinuous, spaced regions of the web which are located on the first surface which exhibit a different surface energy than an adjacent portion of the web. The regions comprise depositions of a preferably whitened, brightened, and/or opacified low surface energy material randomly distributed over the first surface. In a preferred embodiment, the nonwoven web is formed of shaped fibers of substantially non-circular cross-section, preferably a trilobial or delta cross-section, which include whitening, brightening, and opacifying agents within the fiber material.

  • Patent number: 5720740
    Abstract: The invention is a refastenable mechanical fastening system, made of free-formed prongs joined to an embassey or raised substrate. The prongs taper and are nonperendicularly oriented relative to the plane of the substrate. Each prong has an engaging element projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of depositing liquid material onto the embossed or raised portion of a moving substrate, stretching the liquid material in a direction parallel to the plane of the embossed or raised substrate and severing the stretched material to form the distal end and engaging element of the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent garment, specifically a diaper, is also disclosed.
