Fibrous structures, for example pre-moistened fibrous structures, having a novel contact surface (micro protrusion surface) and methods for using the fibrous structures and making the fibrous structures are provided.

A non-woven sheet (10) comprises at least one zone of reinforcement (20a, 20b, 20c, 20d) in which fibers and/or filaments constituting the sheet are bonded together in a reinforcing pattern (22) comprising a plurality of geometric shapes (24), the zone of reinforcement extending over the entire length (L) of the sheet measured in the longitudinal direction (X1), and over a width (l1, l2) strictly less than the width (l) of the sheet (10) measured in a lateral direction (Y1) orthogonal to the longitudinal direction (X1). The sheet (10) thus further comprises at least one non-reinforced zone (30a, 30b). Because of the bonding between the fibers and/or filaments, the elongation of the reinforced zone (20a, 20b, 20c, 20d) under the effect of a given force exerted in a longitudinal direction of the sheet (10) is less than the elongation of the non-reinforced zone under the effect of the same force. Such a sheet (10) may be used in particular for fabricating a laminated assembly.

According to one embodiment, a method of forming a facer includes forming a first layer of nonwoven glass fibers and positioning a second layer of reinforcement fibers atop the first layer of nonwoven glass fibers. The method also includes coating the first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers with a binder composition and pressing the first layer of nonwoven glass fibers and the second layer of reinforcement fibers together between a pair of rollers. The binder composition is then dried to couple the first layer of nonwoven glass fibers and the second layer of reinforcement fibers to form the facer. The first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers are free of a material coating prior to coating of the binder composition.

A primary carpet backing including a structure of at least three layers, wherein a first layer and a third layer including a nonwoven layer of fibers, and wherein a second layer which includes a reinforcement layer of fibers and is located between the first and the third layer, wherein the nonwoven layer of fibers of the first layer has an air permeability of at most 8000 L/m.sup.2.Math.s and the nonwoven layer of fibers of the third layer has an air permeability of at least 1000 L/m.sup.2.Math.s measured according to ISO 9237:1995, wherein the nonwoven layer of fibers of the first layer has a lower air permeability as the nonwoven layer of fibers of the third layer.
