Abstract:
A method of manufacturing a highly absorbent composite sheet mainly consisting of a fibrous web substrate, a super absorbent resin, and a bonding agent to bond said substrate and said super absorbent resin, wherein (a) said fibrous web substrate is an unbonded web having substantially no bonding portions among its constituent fibers, (b) said super absorbent resin and said bonding agent are dispersed in a liquid mixture containing an aqueous medium which does not swell said absorbent resin, (c) the resulting dispersion mixture is added to said unbonded fibrous web substrate to obtain a composite web, and (d) a liquid component is removed from said composite web, whereby fixing of said super absorbent resin onto said fibrous web substrate is effected simultaneously with bonding of constituent webs of said fibrous web substrate with one another.
