CA 2268345

An article made from a fabric layer permeable to a first liquid such as water, blood or urine. The article has one side that repels the liquid and another side which absorbs the liquid. The article can be disposed of by heating in a selected liquid, which dissolves or disperses the article. The article may also have a plastic layer affixed thereto to provide additional impermeability. Two of the fabric layers may be affixed with the impermeable sides facing each other to provide an article capable of absorbing fluids from both sides, yet preventing fluids from penetrating from one side to the other. An optional plastic layer may be juxtaposed between the facing sides to provide a further fluid barrier. A method of disposing of such articles comprises contacting the articles with a sufficiently hot second liquid for a sufficient period of time to disperse or dissolve substantially the articles.

L'invention concerne un article constitué d'une couche de tissu perméable à un premier liquide tel que de l'eau, du sang ou de l'urine. L'article présente une face hydrophobe et une autre face absorbant le liquide. L'article peut être mis au rebut par chauffage dans un liquide sélectionné, lequel dissout ou disperse l'article. Ledit article peut également présenter une couche en plastique fixée à celui-ci pour lui conférer une imperméabilité supplémentaire. Deux des couches de tissus peuvent être fixées aux faces imperméables se faisant face afin d'obtenir un article capable d'absorber les fluides sur ces deux faces, tout en empêchant les fluides de passer d'une face à l'autre. Une couche de plastique facultative peut être juxtaposée entre les faces en vis-à-vis afin de ménager une autre barrière à fluide. L'invention concerne également un procédé de disposition de ces articles consistant à mettre lesdits articles en contact avec un second liquide suffisamment chaud pendant une durée suffisante pour disperser ou dissoudre sensiblement les articles.
