Abstract
Fibrous material comprised of layers of fibers which are essentially unbonded in their initial formation, bonded by minute, adhesive bonds distributed internally in the material according to predetermined nonuniform Z direction distribution characteristics is produced by sequentially forming fiber layers and applying adhesive between the layers in a manner to introduce adhesive into the layers while leaving the surfaces of the material essentially free of adhesive and solely fibrous. Alternative sequences are disclosed providing different predetermined bond distribution characteristics to obtain different absorbency, tensile and tactile properties. The nonuniformly distributed minute adhesive bonds form an internal three dimensional fiber scrim, and there are disclosed modifications of the material incorporating other two dimensional reinforcements integrated with the three dimensional fiber scrim to enhance tensile strength of the finished material. Also disclosed are composite products incorporating the internally adhesively bonded fibrous material with fluff batts and films. Apertured internally bonded fibrous webs are also disclosed.
