Benefits of technology

[0007] Embodiments of the present invention can provide aesthetically pleasing hook and loop fastening systems. Spunlaced loop member materials according to embodiments of the present invention are superior to conventional loop member materials because of the visual consistency and soft hand obtained. Moreover, loop members according to embodiments of the present invention have utility in a broad range of applications, particularly personal hygiene applications, such as disposable diapers, surgical gowns, sanitary napkins, etc.

Problems solved by technology

Spunlaced fabrics have conventionally not been expected to offer any utility in the design of a loop material for a hook and loop fastening system.
This is because the consolidation of fibers via water jets has been considered unsuitable for forming loops for use in hook and loop fastening systems.

Embodiment Construction

[0013] The present invention now is described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0014] Referring now to FIG. 1, a method of forming a loop component for use in a hook and loop fastening system, according to embodiments of the present invention, includes forming a spunlaced fabric having a plurality of loop structures from a plurality of non-interbonded fibers (i.e., fibers not bonded to other fibers) in a fibrous web of material (Block 100), optionally embossing the spunlaced fabric with a decorative pattern or other decorative indicia (Block 200), and optionally bonding the spunlaced...

Abstract

A loop component for use in a hook and loop fastening system, and methods of making same are provided, wherein a spunlaced fabric having a plurality of loop structures is formed by entangling a plurality of non-interbonded fibers in a fibrous web of material. The loop structures are configured to engage hooks from a hook component having a hook density between about 30 and 400 hooks per square centimeter, and have a peel strength of between about 50 grams and 2000 grams. The spunlaced fabric may include a backing layer.

Description

RELATED APPLICATION [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 388,397, filed Jun. 12, 2002, the disclosure of which is incorporated herein by reference in its entirety as if set forth fully herein.FIELD OF THE INVENTION [0002] The present invention relates generally to fastening systems and, in particular, to loop material for hook and loop fastening systems. BACKGROUND OF THE INVENTION [0003] Hook and loop fastening systems are becoming prevalent in many durable and nondurable applications and are replacing other fastening devices such as tape, buckles, zippers and snaps. In general, hook and loop fastening systems include a male hook member, having a plurality of upstanding hook engaging elements, and a female loop member having a plurality of loops in which the hook members become ensnarled to effect fastening engagement of the two components. [0004] Unfortunately, many of the hook and loop fastening systems available today can be difficult...
