An assembly having a substrate bearing an adhesive layer having an extension in a machine direction and an extension in a cross-direction and a number of discrete portions of a backing, each discrete portion having a first major surface bearing a plurality of male fastening elements and a second major surface opposite to said first major surface. Each discrete portion is attached to the adhesive layer through the second major surface. A sum of a maximum density of the discrete portions of the backing along the extension of the adhesive layer in the cross-direction and a maximum density of the discrete portions of the backing along the extension of the adhesive layer in the machine direction is at least 0.8 cm−1. The assembly can releasably adhere to a fibrous material having a plurality of female fastening elements through a combination of a mechanical and an adhesive bonding mechanism. Methods of making the assembly and disposable absorbent articles containing the assembly are also described.

1. An assembly comprising: a substrate bearing an adhesive layer having an extension in a machine direction and an extension in a cross-direction; anddiscrete portions of a backing, each discrete portion having a first major surface bearing a plurality of male fastening elements and a second major surface opposite to said first major surface, and each discrete portion being attached to the adhesive layer through its second major surface,wherein a sum of a maximum density of the discrete portions of the backing along the extension of the adhesive layer in the cross-direction and a maximum density of the discrete portions of the backing along the extension of the adhesive layer in the machine direction is at least 0.8 cm−1, and wherein the assembly can releasably adheres to a fibrous material having a plurality of female fastening elements through a combination of a mechanical and an adhesive bonding mechanism. 2. The assembly according to claim 1, wherein the maximum density of the discrete portions of the backing along the extension of the adhesive layer in the cross direction and in the machine direction is independently from each other at least 0.5 cm−1. 3. The assembly according to claim 1, wherein an average maximum extension of the discrete portions of the backing is at least 1 mm. 4. The assembly according to claim 1, wherein an average distance between the discrete portions of the backing is at least 1 mm. 5. The assembly according to claim 1, wherein an average thickness of the backing is between 10 μm and 1 mm. 6. The assembly according to claim 1, wherein the adhesive layer comprises a pressure-sensitive adhesive. 7. The assembly according to claim 1, wherein the adhesive exhibits a 90° peel adhesion from a smooth polyethylene surface of between 1 N/inch and 10 N/inch. 8. The assembly according to claim 1, wherein an average surface density of the male fastening elements with respect to the surface area of the adhesive layer including the surface area of the discrete portions of the backing is between 10/cm2 and 5,000/cm2. 9. The assembly according to claim 1, wherein the male fastening elements are selected so that they can be releasably engaged with a fibrous material having an area weight of less than 350 g/m2. 10. A method of preparing the assembly according to claim 1, the method comprising; providing the substrate;applying the adhesive layer to an exposed surface of the substrate;providing a multitude of the discrete portions of the backing having the first major surface bearing the plurality of male fastening elements; andadhering the discrete portions of the backing through the second major surface to the exposed surface of adhesive layer such that the assembly according to claim 1 is prepared. 11. A disposable absorbent article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet opposite to said top sheet, a liquid-absorbent core between said top sheet and said back sheet, two longitudinal edges, a first end region, second end region, and the assembly according to claim 1 positioned to secure said disposable absorbent article to at least one of a body or an undergarment of a person. 12. The disposable absorbent article according to claim 11, wherein the disposable absorbent article is a disposable diaper comprising tape tabs disposed adjacent each longitudinal edge in the first end region, each of said tape tabs comprising the assembly, said disposable absorbent article further comprising a fibrous material in the second end region capable of mechanically engaging with the male fastening elements of the assembly. 13. The disposable absorbent article according to claim 11, wherein the disposable absorbent article is a disposable sanitary napkin bearing the assembly on the back sheet. 14. An assembly comprising: a substrate bearing an adhesive layer having an extension in a machine direction and an extension in a cross-direction; andrectangular discrete strips of a backing, each discrete strip having a first major surface bearing a plurality of male fastening elements and a second major surface opposite to said first major surface, said discrete strips being attached to the adhesive layer through their second major surfaces in a parallel fashion along the machine direction and at a distance in the cross-direction from each other such that an alternating sequence of multiple parallel strips of exposed adhesive layer and of the strips of the backing is obtained,wherein a sum of a maximum density of the discrete strips of the backing along the extension of the adhesive layer in the cross-direction and a maximum density of the discrete strips of the backing along the extension of the adhesive layer in the machine direction is at least 0.8 cm−1, and wherein the assembly can releasably adhere to a fibrous material having a plurality of female fastening elements through a combination of a mechanical and an adhesive bonding mechanism. 15. The assembly according to claim 14, wherein an average maximum extension of the rectangular discrete strips in the cross-direction is at least 1 mm. 16. The assembly according to claim 14, wherein the distance in the cross-direction between the rectangular discrete strips averages at least 1 mm. 17. The assembly according to claim 14, wherein an average thickness of the rectangular discrete strips is between 10 μm and 1 mm. 18. The assembly according to claim 14, wherein a ratio of a sum of surface areas of the rectangular discrete strips to a surface area of the adhesive layer defined by the extension in the machine direction times the extension in the cross-direction is between 0.25 and 0.65. 19. The assembly according to claim 14, wherein the adhesive layer comprises a pressure-sensitive adhesive. 20. A disposable absorbent article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet opposite to said top sheet, a liquid-absorbent core between said top sheet and said back sheet, two longitudinal edges, a first end region, a second end region, and the assembly according to claim 14 positioned to secure said disposable absorbent article to at least one of a body or an undergarment of a person. 21. The assembly according to claim 1, wherein at least one of the discrete portions of the backing is encompassed by the adhesive layer.
