	Pattern-unbonded nonwoven web and process for making the same - Patent 5858515
		The pattern-unbonded nonwoven fabric of the present invention has sufficient structural integrity and dimensional stability that, unlike certain of the prior art loop materials, the need for attachment to a support or backing layer to anchor the fibers or filaments within the nonwoven fabric is eliminated.
		The pattern-unbonded nonwoven fabric of the present invention is relatively inexpensive to produce, especially in comparison to conventional loop materials formed by knitting, warp knitting, weaving, and the like, yet exhibits satisfactory, comparable and/or improved peel and shear strengths as compared to conventional loop fastening materials when used with commercially available hook fastener materials.
		Within the continuous bonded areas 6, the fibers or filaments of the nonwoven web are thoroughly bonded or fused together, and desirably are non-fibrous, whereas within the unbonded areas 8 the fibers or filaments of the nonwoven fabric or web are substantially or completely free of bonding or fusing and retain their fibrous structure.

	Innovative Products from Stitch-Bonded-Hydroentangled Nonwoven Composites for Technical Applications
		Putting on a nonwoven of fine fibres by means of water jets of high energy, we succeeded in compressing the loop surface and thus, we achieved a combination of the good filter properties of the upper pile surface with a fine-pore layer serving to reclaim small particles (up to 0.3 µm).
		The hydroentangled nonwoven put on the stitch-bonded nonwoven compresses the pores of the loop surface in such a way that the air permeability of the basis stitch-bonds is reduced to 1/3 or even 1/4.
		The stitch-bonded-hydroentangled nonwoven composites described are compounds consisting of at least one stitch-bonded nonwoven and a surface compressed by fibres.

	Creped nonwoven laminate loop fastening material for mechanical fastening systems (US5614281)
		The raised areas of the creped nonwoven layer are separated by non-raised areas having relatively higher fiber density and relatively lower z-directional fiber orientation when compared to the fiber density and z-directional fiber orientation of the raised areas.
		The primary areas of bonding or attachment of the bottom surface of the nonwoven layer to the top surface of the underlying support layer are the non-raised areas; in addition, some secondary bonding of the nonwoven layer to the support layer outside of the non-raised areas may exist.
		The creped structure of the nonwoven layer further provides resistance against compression of the fibers forming the hook receiving loop material during use, thereby facilitating entry and engagement of hook elements projecting from the hook material.
