Embodiment Construction

[0053] Although the invention has been shown and described herein with reference to specific embodiments, the invention is not limited to the details shown. On the contrary, various improvements can be implemented on this basis within the scope of equivalents of the claims without departing from the present invention. In addition, the embodiments used for illustration in the figures are not shown to scale and are not limited to the scales shown.

[0054] As used herein, the term "nonwoven" means a web of fibers having a structure made of interposed individual fibers, but which is not made in an orderly or discernible manner such as occurs in a woven or knitted web . As defined by INDA (Nonwovens Industry Association of America), the trade association representing the nonwoven fabrics industry, nonwoven fabrics generally refer to fibers or filaments entangled mechanically, thermally or chemically (and by perforation) and bonded together sheet structure or fiber network struct...

Abstract

A simplified manufacturing technique to directly form a unitized composite structure with at least one relatively flat surface and at least one sinuous element in an internally-bonded unitized composite is provided. A matrix of fibrous and or other materials is deposited in layers which are subsequently formed into corrugated or wave-like shapes and exposed to an activation step. At least one element is composed of a contractive material which shrinks when activated, such as by heating in an oven, to become relatively flat and optionally bonded to at least one other non-contractive layer which remains in a sinuous shape after the activation step.

Description

[0001] This application asserts under 35 U.S.C §119(e) the title filed on June 14, 2006 as "WAVE-LIKE STRUCTURES BONDED TO FLATSURFACES IN UNITIZED COMPOSITES AND METHODS FORMAKING SAME Priority to U.S. Provisional Patent Application No. 60 / 813,433, "Structures and Methods of Making The Same," the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a method of manufacturing a composite composite textile structure having at least one sinusoidal element and at least one relatively planar element attached to each other. Background technique [0003] Typically manufactured nonwovens, films, textiles, paper and paperboard materials are relatively smooth, have a flat surface, have a uniform density, and are relatively thin compared to their length and width. When a thicker structure with at least one smooth side is desired, at least one relatively flat roll product material is combined and bonded with at least on...
