摘要:
The present invention is directed to a method of forming a laminate absorbent structure, and a resulting package containing a single continuous running web of the laminate material. Notably, formation of the material is effected by blending a curtain of adhesive fibers with a curtain of particulate material, and depositing the mixture on a moving substrate, preferably provided in the form of a tissue layer. A second substrate, also preferably comprising a tissue layer, is applied on top of the deposited mixture, and pressure applied to form the laminated structure. Notably, attendant to packaging of the laminated material, adjacent layers of the material tend to nest into one another, to form a sandwich in which the density of the material in the package is more than 1.5 times the density of the material after its removal from the package.
