Abstract
En absorberende struktur inkluderende et væsketilegningslag og et fibervæskelagringslag i væskekommunikasjon med til-egningslaget er beskrevet. Lagringslaget inkluderer SAP-partikler.ilegningslaget inkluderer syntetiske fibre og fibrene er lateksbundet. Et fluid tilegnings- og/eller fordelingslag (ADL) inneholdende minst to lag, et topplag av lateksbundne syntetiske fibre og et bunnlag av lateks og/eller termisk bundne cellulosefibre og fremgangsmåte for fremstilling derav er beskrevet. Det syntetiske fiberlag er høyt porøst og tilveiebringer rask fluidtilegning under last. Celluloselaget tilveiebringer Z-direksjon kappilær-kraft for å trekke fluid inn i det absorberende produkt, for å gi midlertidig fluidimmobilisering, og for å virke som en ledning for fluid til å bli trukket inn i umettede deler av det permanente fluid-lagringslag. ADL av oppfin-nelsen tilveiebringer øket beskyttelse mot lekkasje rela-tivt til enkeltlag ADLS.An absorbent structure including a liquid addition layer and a fibrous liquid storage layer in liquid communication with the application layer is described. The storage layer includes SAP particles. The coating layer includes synthetic fibers and the fibers are latex bonded. A fluid acquisition and / or distribution layer (ADL) containing at least two layers, a top layer of latex-bonded synthetic fibers and a bottom layer of latex and / or thermally bonded cellulosic fibers, and methods of making the same are described. The synthetic fiber layer is highly porous and provides rapid fluid accumulation under load. The cellulosic layer provides Z-direction capillary force to draw fluid into the absorbent product, to provide temporary fluid immobilization, and to act as a conduit for fluid to be drawn into unsaturated portions of the permanent fluid storage layer. ADL of the invention provides increased leakage protection relative to single layer ADLS.
