Layered absorbent structure with zoned weight of a unit area

 

Described absorbing product that contains absorbent inner part, including many absorbing layers and absorbing layers interact with each other in such a way that the absorbed liquid is mainly localized in designed for this purpose, a highly saturated capillary suction layer. Localization of liquid in capillary suction layer increases the ability of this layer to move the liquid under the action of capillary forces due to the higher level of saturation and increased the number of available fluid. In additional aspects, at least one primary layered region may be heterogeneous, selectively zoned distribution of weight per unit of area. In specific embodiments, performing at least one primary layer region of the target site of the primary layered region may have a lower weight per unit area in comparison with the weight of a unit area of non-target part of the initial layered region. 2 C. and 20 C.p. f-crystals, 20 ill., 3 table.
