Soft, absorbent, unitary, laminate-like fibrous web
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.
