摘要： Disclosed is a non-nested, two-ply, absorbent fibrous sheet material consisting of two webs which each have a plurality of crests and depressions on its surface facing the other web. The crests on each web are positioned between the crests of the other web and are spaced from the depressions of the other web to leave spaces in the sheet material for increased absorbency and bulk. The two webs are joined together at locations intermediate the crests and depressions of at least one of the webs, preferably by mechanical welding in a manner which produces perforations in the sheet material. Also disclosed is the method and apparatus for making the two-ply sheet material.

摘要： The method of the invention consists of forming a web of substantially planar-aligned fibers, applying a surface disposition of bonding material to one side of the web to penetrate only part way through the web in order to form a first surface region having the surface bonding material and a central core region free from the surface bonding material and bounded on the side opposite the first surface region by a second surface region, 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 the surface bonding material in the first surface region and penetrates through the central core region to connect the first and second surface regions together, and creping the web to decrease the fiber concentration in the central core region to less than that in the first surface region. In a preferred method, a surface disposition of bonding material is also applied to the second surface region, and the surface bonding material applied to the first surface region is in a fine, spaced-apart pattern and is used to adhere the bonded portions of the first surface region of the web to a creping surface in order to finely crepe those portions of the web upon creping the web from the creping surface.

摘要： Disclosed is a unitary or integral laminate-like fibrous web having a first and second surface region and a central core region which has less fiber concentration than the first surface region. The first 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 the first 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 by penetrating to at least within a fiber thickness of the web surface to provide abrasion-resistance for that surface region. In a preferred embodiment, the surface bonding material in the first surface region is applied in a fine, spaced-apart pattern and those areas where it is disposed have been finely creped.
