Absorbents containing stiffened fibres and superabsorbent materials

Absorbent structure containing stiffened fibres and super-absorbent material comprises a fluid pervious top sheet and a fluid impervious back sheet surrounding a fluid acquisition and distribution layer 110 of bonded chemically stiffened cellulosic fibres with an average dry density of less than 0.30 g/cc, and average density on wetting with a 1% aq. sodium chloride soln. of less than 0.2 g/cc and an average dry basis weight between 0.001 and 0.10 g/cc and a fluid storage layer 108 below this having over 15% superabsorbent material. Absorbent structures having a fluid acquisition/distribution layer (110) with an average dry density of less than about 0.30 g/cc, an average density upon wetting with 1.0 % NaCl aqueous solution of less than about 0.20 g/cc, and an average dry basis weight from about 0.001 to about 0.10 g/cm2; and a fluid storage layer (108) positioned beneath the acquisition/distribution layer (110) comprising at least about 15 % superabsorbent material. The fluid acquisition/distribution layer (110) comprises from about 50 % to 100 % chemically stiffened cellulosic fibres and from 0 % to about 50 % binding means. Absorpčná štruktúra (106) určená na zachytávanie, rozdeľovanie a akumuláciu telesných tekutín obsahuje zachytávaciu a rozdeľovaciu vrstvu (110) a akumulačnú vrstvu (108), umiestnenú pod zachytávacou a rozdeľovacou vrstvou. Zachytávacia a rozdeľovacia vrstva (110) má priemernú hustotu po nasýtení 1 % vodným roztokom chloridu sodného, prepočítanú na suchú hmotnosť, nižšiu ako 0,20 g. cm -3 a jej vrchná povrchová plocha je od 15 % do 90 % vrchnej povrchovej plochy akumulačnej vrstvy.ŕ
