Abstract
A loop fastener product is provided including a generally planar nonwoven base of fibers, and a field of loop structures extending from the generally planar nonwoven base of fibers. The field includes (a) generally parallel engageable bands in which the loop structures are exposed on a front surface of the nonwoven base for releasable engagement by hooks; and (b) generally parallel bond area bands, separating the bands of loop structures, in which a major proportion of the loop structures are bonded together in the plane of the nonwoven base. Methods of forming loop fastener products are also provided.
Claims21
A loop fastener product comprising
- a generally planar nonwoven base of fibers, and
- a field of loop structures extending from the generally planar nonwoven base of fibers, the field comprising
- generally parallel engageable bands in which the loop structures are exposed on a front surface of the nonwoven base for releasable engagement by hooks;
- and
- generally parallel bond area bands, separating the bands of loop structures, in which a major proportion of the loop structures are bonded together in the plane of the nonwoven base.
A method of forming a loop fastener product, the method comprising
- forming a field of loop structures extending upwardly from a front surface of a generally planar nonwoven base and exposed for releasable engagement with hooks;
- and then
- embossing the front surface of the nonwoven base to bond the loop structures to each other in generally parallel bond area bands, in which the loop structures extend generally in the plane of the nonwoven base and are substantially unavailable for engagement, while leaving engageable bands, between the bond area bands, in which loop structures remain available for engagement.
