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.
A puncture sealing agent for a tire is disclosed that has a rubber latex, an adhesive agent, and an anti-freezing agent, wherein glycerin, potassium acetate or a solution of glycerin and potassium acetate is used as the anti-freezing agent.
The present invention relates to a flushable fibrous structure that is particularly useful as a disposable tissue product and as a component (e.g., topsheets) for absorbent articles such as catamenial pads, diapers, incontinent articles and the like. The invention specifically relates to a flushable fibrous structure that has an in-use wet tensile strength of at least about 100 g/in. and a disposal wet tensile strength of not more than about 30 g/in. The invention also relates to absorbent articles comprising the fibrous structures, and methods for making the structures.
The present invention is directed toward a multilayer film which includes a first surface layer and a second surface layer. The first surface layer is composed of materials which disintegrate when subjected to conditions present in conventional sewage systems. The second surface layer is formed from a material which is essentially inert to water, urine and other bodily fluids. Typically, the second surface layer is an extremely thin coating which provides a waterproofing effect. The multilayer film may be utilized as an outer cover in a wide variety of products such as, for example, disposable diapers and feminine care products such as sanitary napkins. In one desirable embodiment the multilayer film includes only these two layers so that the material may be flushed down a conventional toilet without clogging the sewage system because the first surface layer rapidly disintegrates in water leaving only the thin, gossamer second surface layer which can pass through the sewage system without adversely affecting it.
The present invention is directed to saturants for fibrous webs that will confer upon those webs the ability to be heat sealed to many materials without compromising the drapability of the fibrous webs. The present invention is further directed to fibrous webs saturated with the saturant of the present invention and methods for saturating such webs. The invention is further directed to packages or containers comprising the saturated webs and methods of manufacturing such packages. The invention is further directed to temperature sensitive adhesive coatings that can be used with the saturated webs and a method for applying the coating.
