  • Patent number: 6060638
    Abstract: The present invention is directed to a matched permeability liner/absorbent structure system, suitable for use in absorbent articles, in which the permeability of the bodyside liner is correlated with the permeability of the subjacent layer of the absorbent structure, such as a surge layer. The inventors have observed that by appropriately matching the permeability of the liner material to the permeability of the subjacent layer, liquid intake performance of the liner and subjacent layer materials can exceed liquid intake performance of the subjacent layer material alone. Thus, in accordance with an embodiment of the present invention, the permeability of the bodyside liner is set within a specified range of that of the subjacent layer such that the liner/subjacent layer liquid intake performance is improved.

  • Patent number: 5695855
    Abstract: Disclosed herein is a durable adhesive-based ink-printed polyolefin nonwoven which is suitable for a number of uses the most basic of which is where a printed nonwoven is needed and that nonwoven will possibly be subjected to an amount of abrasion which would prematurely remove the ink from the surface of the nonwoven web. The two main components of the present invention are an adhesive-based ink and a polyolefin-based substrate onto which the adhesive-based ink is applied. The resultant composite must have a crock value of 4 or greater.
