LAMINATED ABSORBING STRUCTURE WITH ZONED WEIGHT OF AREA UNIT Russian patent published in 2003 - IPC

FIELD: absorbing products. SUBSTANCE: absorbing product has absorbing internal part including many absorbing layers interacting so that absorbed liquid is mainly localized in designed for the purpose highly-saturated capillary sucking layer. Liquid localization in this capillary sucking layer increases capability of this layer to move liquid under effect of capillary forces due to higher saturation level and increased amount of available liquid. In additional aspects, at least, one primary laminated region may have heterogeneous selectively zoned distribution of weight of area unit. In concrete versions of realization of, at least, one primary laminated region, specific section of primary laminated region may have lower weight of area unit as compared with that of nonspecific part of primary laminated region. EFFECT: higher efficiency of use. 22 cl, 14 dwg, 3 tbl
