A disposable open-form diaper, comprising: a chassis comprising a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core structure disposed between the topsheet and the backsheet; a front waist region; a rear waist region; and a crotch region disposed between the front waist region and the rear waist region; a longitudinal axis and a lateral axis; a fastening member joined to the chassis in the rear waist region and extending laterally away from the longitudinal axis, including a first fastening component disposed thereon; and a second fastening component disposed on the front waist region; wherein one of both of the first and second fastening components comprises a section of nonwoven web material on which an array of hooks is formed, wherein the section of web material comprises filaments of polymeric material; the nonwoven web material having a machine direction of formation, the filaments of polymeric material having a machine direction bias and being consolidated and bonded in a pattern of thermal bonds, the section of nonwoven web material comprising a section of loops material having a machine direction dimension of at least 20 mm, a cross direction dimension of at least 20 mm, and a surface area of at least 314 mm2, and being bonded in a continuous loops-forming bond, or pattern of discrete loops-forming bonds, wherein: any identifiable linear path along the section of loops material that has a width greater than 2 mm and forms an angle of 45 degrees or less with the machine direction (MD) at least partially overlies the loops-forming bond or bonds in the pattern, at a plurality of locations along the path; wherein at least some of the hooks are thermally formed at least in part of the polymeric material of the filaments such that at least part of the array is integral with the nonwoven web material; wherein when the section of nonwoven web material is deemed to lie along an x-y plane, the hooks are formed to extend in a z-direction with respect to the x-y plane, and hook over along one or more hook directions that cross the machine direction of formation of the web material at an angle of no more than 45 degrees.
