Disclosed is a unitary or single-ply, laminate-like fibrous web having first and second surface regions and a central core region which has less fiber concentration than the surface regions. Each surface region has a surface disposition of bonding material disposed only in that region to form a strong, abrasion-resistant surface. The central core region has a penetrating disposition of bonding material extending through that region in a fine, spaced-apart pattern occupying less area in the plane of the web than the surface bonding material in either surface region. The penetrating bonding material in the central core region penetrates entirely through that region and connects the first and second surface regions together. The area where the surface bonding material is disposed in at least one of the surface regions has been finely creped.The preferred method of the invention consists of (a) forming a web of substantially planar aligned fibers, (b) applying a surface disposition of bonding material to one side of the web to penetrate only part way though the web in order to form a first surface region having a surface bonding material and a central core region free from the surface bonding material, (c) applying a surface disposition of bonding material to the second surface region to penetrate only through that surface region, (d) applying a penetrating disposition of bonding material to one side of the web in a fine, spaced-apart pattern which occupies less area in the plane of the web than either of the surface bonding materials and penetrates through the central core region to connect the first and second surface regions together, and (e) adhering the bonded portions of one surface region of the web to a creping surface in order to finely crepe those portions of the web upon creping of the web from the surface region.
