Abstract: Loop components for hook-and-loop fasteners and methods of making the same. The loop components comprise single-layer nonwoven webs having a first side, a second side opposite the first side and a thickness therebetween. The fibers of the nonwoven webs are partially fused on the first side to create a skin layer. The nonwoven webs have a basis weight ranging from 20 gsm to 50 gsm and a pressure drop index ranging from 40 to 100.

Abstract: A composite fabric includes a nonwoven fabric layer having non-bonded areas and a structured film layer discontinuously bonded to the nonwoven fabric layer. The discontinuously bonded nonwoven fabric layer and the structured film layer share an overlapping area with at least one set of coincident bond sites. The discontinuously bonded nonwoven fabric does not have another bonding pattern in the overlapping area distinct from the at least one set of coincident bond sites. A method of forming a composite fabric is also described. The method includes forming a fiber layer including a mat of at least partially unconsolidated fibers, positioning a structured film layer and the fiber layer such that they overlap, and discontinuously bonding the mat into a discontinuously bonded nonwoven fabric while simultaneously bonding the structured film layer to the nonwoven fabric layer. An apparatus for forming a composite fabric is also described.

Abstract: Problem: The present invention provides a surface fastener loop member, sanitary article, and diaper that have favorable flexibility, engaging strength, and printing properties, and that can be manufactured at low cost. Resolution: A loop member for a surface fastener, containing a loop layer and a base material layer; wherein the loop layer comprises a short fiber nonwoven material; the base material layer comprises a short fiber nonwoven material, and is calendared; the ratio of the average fiber fineness of the fibers in the loop layer and the average fiber fineness of the fibers in the base material layer as expressed by [average fiber fineness of fibers in the loop layer]/[average fiber fineness of fibers in the base material layer] is 1.5 to 30, and the thickness of the base material layer is 15 μm to 100 μm.
