Abstract
There is provided a laminate of a thermoplastic backing to a fibrous web. This laminate, for example, could be used as a loop laminate for use in a hook and loop fastening system or an intermittently bonded elastic fibrous laminate. The laminate comprises a thermoplastic backing layer, having a first face and a second face. The backing layer has a plurality of projections extending from at least the first face of the backing. A fibrous web is attached to the backing at the location of at least some of the projections. The thermoplastic material of the backing, at the location of the projections, penetrates into the fibrous web encapsulating at least in part fibers of the fibrous web. The fibrous web preferably penetrates into at least some of the projections. The fibrous web is generally not attached, or very lightly attached, to the backing layer over at least some portion of the distance between adjacent projections. This allows for a low cost fibrous web laminate that can be directly extrusion formed with a backing without compromising the fibrous web's performance between the attached projections.
