  • Patent number: 5074013
    Abstract: A releasable fabric joining apparatus is disclosed, comprising a first piece of material which includes a planar body substrate and a planar loop substrate which has a first loop substrate secured coplanar with the planar body substrate. The planar loop substrate also includes a second loop substrate surface formed of woven fabric having plural loops of thread. A second piece of material forms another part of the apparatus, and has at least one surface with a grip face provided with plural, outwardly-extending filamentary hooks releasably received by the plural loops of thread. In a preferred embodiment, the first piece of material is woven fabric, and the second piece of material is loop-type Velcro. The present invention may be used in many different embodiments, such as in a non-slip shoelace, baby bib, and in other applications wherein a need exists to releasably secure to pieces of fabric while ensuring that the joined pieces have high resistance to shear stress.
