Abstract: A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the product as possible, while providing optimum intake performance through appropriate control of the composite properties. The low saturation in this layer provides void volume for the incoming insult as well, as a high permeability, thus increasing the intake rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide an appropriately high level of capillary tension to provide enough control of the liquid to stop leakage from occurring. This low saturation layer is used in addition to a surge material and provides intake functionality in addition to that provided by the surge material. In particular aspects of the invention, the body side layer of the absorbent core does not extend over the entire surface of the overall absorbent core, therefore is not used as the high saturation, wicking layer, but as the intake layer. This arrangement also allows the intake layer to be in direct contact with the incoming liquid, therefore allowing for more immediate access and improved intake function. In additional aspects, at least one primary layer region can have a non-uniform, selectively zoned basis weight distribution. Particular configurations of the at least one primary layer region can be constructed with a target area of such primary layer region having a basis weight which is less than a basis weight of another non-target portion of the primary layer region. Moreover, at least one primary layer region can have a heterogeneous structure. In particular constructions, the at least one primary layer region can include a plurality of two or more sublayers.

Abstract: Disclosed herein is a liquid absorbent material that is particularly useful as a liner material for personal care absorbent articles such as diapers, training pants, incontinence garments, sanitary napkins, bandages and the like. The material contains a plurality of peaks across its surface at spaced-apart intervals separated by channels. Disposed within the peaks is a liquid absorbing material capable of absorbing body exudates and liquids in general. Due to the materials and the nature of the construction of the present invention, when used as a liner material for personal care absorbent articles such as diapers, it tends to reduce the total surface area in contact with the infant's skin and it also provides a plurality of air channels within the diaper from the front waistband to the back waistband of the diaper thereby providing a path for increased air circulation. The material of the present invention has other uses as, for example, a packing or liner material for packaging and shipping materials containing liquids. In addition, the peaks can contain other additives such as soaps so the material can be used as a wash pad or cloth.
