Abstract:
A water dispersible fibrous fabric comprising:a fibrous substrate, wherein less than about 20% of the fibers comprising the fibrous substrate have a length of about 6-10 mm; and a water-dispersible binder; wherein said binder is an ion-sensitive composition comprising a sulfonate anion modified polymer and a non-crosslinking poly(ethylene-vinyl acetate), wherein the composition is insoluble in a neutral salt solution containing at least about 0.3 weight percent salt, said salt comprising one or more monovalent ions; wherein said binder comprises about 5% to about 65% by weight of said fibrous fabric and said fibrous substrate comprising about 35% to about 95% by weight of said fibrous fabric; and wherein the fabric is dispersible in an aqueous environment containing up to about 200 ppm of one or more divalent and/or multivalent ions.
