US 5,595,567 A · Nonwoven female component for refastenable fastening device

Abstract

A loop fastening material having an elastomeric backing joined with a nonwoven web. The backing preferably comprises an elongated orientation, a relaxed orientation and a path of response along which the backing contracts from its elongated orientation to its relaxed orientation. The nonwoven web preferably comprises filaments that are secured to each other at fixed regions by inter-fiber bonds forming a nonwoven web bonding pattern comprising nonwoven web bonding pattern elements. Between the fixed regions, the nonwoven web preferably comprises unsecured regions. The nonwoven web is preferably joined with the backing while the backing is in its elongated orientation. Construction bonds forming a construction bond pattern join the nonwoven web with the backing. In preferred embodiments of the present invention the construction bond pattern intersects with at least two points of each nonwoven web bonding pattern element. Thus, when the backing is contracted from its elongated orientation to its relaxed orientation, the unsecured regions of the nonwoven web become shirred and extend outwardly from the backing to form catching regions that are capable of entangling the engaging elements of a complementary male fastening component.

Dependent claims

A female component of a refastenable fastening device capable of engaging a complementary hook fastening component, said female component comprising:

a backing having an elongated orientation, a relaxed orientation, and a path of response along which said backing contracts from said elongated orientation to said relaxed orientation;
and
a nonwoven web in contact with said backing, said nonwoven web comprising filaments having unsecured regions and fixed regions, said fixed regions comprising inter-fiber bonds joining said filaments and forming a nonwoven bonding pattern comprising a multiplicity of nonwoven bonding pattern elements;
and
a construction bond pattern comprising at least one construction bond for joining said nonwoven web with said backing, said construction bond pattern intersecting with at least two points of each of said nonwoven bonding pattern elements, wherein said unsecured regions of said filaments are shirred when said backing is caused to return to its relaxed orientation, forming catching regions capable of entangling the male component of a refastenable fastening device.
