ABSTRACT:
The present invention is directed toward a fibrous web having improved strength characteristics which, in the presence of water, rapidly disintegrates when subjected to standardized agitation testing. The web includes a plurality of fibers joined together by a binder. The binder makes up from about 0.20 to about 15 percent of the dry weight of the web. The binder is formed from a blend of from about 10 to about 40 weight percent of a water dispersible, high molecular weight amorphous polyester having one or more ionic substituents attached thereto; from about 10 to about 40 weight percent of an elastomeric latex emulsion; from about 20 to about 40 weight percent of a xerogellant; and from about 5 to about 20 weight percent of a plasticizing agent. The fibrous web is useful in the formation of disposable diapers and feminine care products which may be flushed down the toilet.
