Process for manufacturing absorbent sanitary paper products

摘要

A method of manufacturing an absorbent sanitary paper product having a machine direction, a cross-machine direction orthogonal and co-planar thereto, and a Z-direction orthogonal to both the machine- and cross-machine directions is disclosed. The method provides the steps of: providing a first and second network of fibers each having opposing first and second sides where each fiber of the first network of fibers has a longitudinal axis generally disposed within the plane comprising the machine- and cross-machine-directions; applying a first bonding layer to one of the first and second sides of the first network of fibers; applying a first and second second network of fibers to the first bonding layer; and, placing the first and second network of fibers into face-to-face contacting engagement.

1. A method of manufacturing an absorbent sanitary paper product having a machine direction, a cross-machine direction orthogonal and co-planar thereto, and a Z-direction orthogonal to both the machine- and cross-machine directions, said method comprising the steps of:
providing a first first network of fibers having opposing first and second sides, each fiber of said first first network of fibers having a longitudinal axis generally disposed within the plane comprising the machine- and cross-machine-directions; providing a second first network of fibers having opposing first and second sides, each fiber of said second first network of fibers having a longitudinal axis generally disposed within the plane comprising the machine- and cross-machine-directions; applying a first bonding layer in a first pattern to said first side of said first first network of fibers; applying a second bonding layer in a second pattern to said first side of said first first network of fibers; applying a first second network of fibers to said first bonding layer, each individual fiber comprising said second network of fibers having a longitudinal axis generally disposed in the Z-direction; applying a second second network of fibers to said second bonding layer, each individual fiber comprising said second second network of fibers having a longitudinal axis generally disposed in the Z-direction, said first second network of fibers and said second second network of fibers being different; and, placing said second side of said first first network of fibers and said second side of said second first network of fibers into contacting engagement.
