A hook-and-loop fastener has a hook element comprising a substrate having a face from which projects a multiplicity of hooks and a loop element formed by of a fiber web. The fiber web is formed by a homogenous mixture of first multicomponent filaments each formed by a high-melting-point polymer and a low-melting-point polyolefinic polymer and second polyolefinic monocomponent filaments. The first filaments constitute between 20% and 80% by weight of the mixture. The fiber web has a face formed with a patterned array of dense bonded regions of a predetermined small thickness interspersed with less dense open regions of a predetermined big thickness substantially greater than the small thickness of the small thickness interspersed with less dense open regions of a predetermined big thickness substantially greater than the small thickness of the bonded regions so that the filaments of the open regions form loops.

Filter media comprising non-woven fiber webs having one or more advantageous physical properties are generally described. In some embodiments, a filter media and/or non-woven fiber web described herein comprises a combination of fibers that results in enhanced physical properties. For example, the non-woven fiber web may comprise a combination of fiber types that is advantageous, such as a combination comprising fibrillated fibers, glass fibers, and/or binder fibers. In some cases, the filter media and/or non-woven fiber web comprising the combination of fibers may be formed into undulations (e.g., by a creping and/or microcreping process) to further enhance the physical properties of the filter media and/or non-woven fiber.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

The present invention relates to non-woven fabric with enhanced hardness and sound absorption, more specifically to non-woven fabric that includes two or more kinds of polyester-based materials and non-circular cross-section fiber, and thus has enhanced hardness and sound absorption as well as improved formability, and that can be applied for an automotive undercover.
