Hook-and-Loop Fastener

Abstract

A fastening system comprising a sheet of filaments that form a plurality of loops that are bent to form hooks, attached to a support matrix, such that when a first sheet and second sheet of filaments are brought into contact, the hooks can mate with the loops of the opposing sheet in a reversible locking position. In a second embodiment, the fastening system comprises a first base material having a multiplicity of filament loops and a second base material having a carpet of straight filaments, each filament having at least one notch sized to lock onto the filament loops of the first base material. Methods for manufacturing said materials are also described.

1 . A hook-and-loop fastening material, comprising:
 a carpet surface comprised of a plurality of hooked loops of filaments, each loop being attached to a support matrix surface, wherein each loop of the plurality of hooked loops rises up perpendicular to the support matrix surface, and each loop is bent into a J-hook at a point at least halfway along the plane of the loop rising perpendicular to the support matrix surface.   
     
     
         2 . The hook-and-loop fastening material of  claim 1 , wherein each said loop is placed in an irregular pattern within each row. 
     
     
         3 . The hook-and-loop fastening material of  claim 1 , further comprising a second carpet surface comprised of a second plurality of hooked loops of filaments, each loop of the second plurality of hooked loops being attached to a second support matrix surface, wherein each loop of the second plurality of hooked loops rises up perpendicular to the support matrix surface and is bent into a J-hook at a point at least halfway along the plane of the loop rising perpendicular to the second support matrix. 
     
     
         4 . A fastening material, comprising:
 a first base web having a plurality of filament loops attached in a series of rows and columns;   a second base web having a plurality of fastening strands mounted on the base web in rows and columns, each fastening strand attached in substantially perpendicular to the base web, each fastening strand having at least one notch with a mouth sized to fit the filament loops on the first base web.
