Double sponge to remove waste, absorb liquids and clean surfaces

Abstract

A two-layered sponge article with different textures is described. The two layers are joined at their contour so as to form a cavity, making it possible to squeeze in an independent and selective way each of the layers that constitute it. One layer is an abrasive layer, woven or extruded, formed with threads of materials resistant to oxidation, and the other layer is an absorbent layer, with high absorption capacity. This cleaning article further has a thickness less than 20 mm, and has an absorption of up to 30 grams of water per gram of absorbent material. Given the thickness of the article, it provides: (a) sensitivity on contact with a surface being cleaned to the surface thereby allowing scrubbing of specific areas of greater accumulation of dirt and (b) curling on itself, without deformation upon release of the force that rolled it, making it possible to access tight spaces to clean without deforming the article.

         4 . The dual sponge according to  claim 1 , wherein the absorbent layer has a thickness in a range of about 5.0 mm to about 15 mm. 
     
     
         5 . The dual sponge according to  claim 1 , wherein the absorbent layer is hydrophilic. 
     
     
         6 . The dual sponge according to  claim 1 , wherein the absorbent layer has a water-absorbing capacity of up to about 30 grams of water per gram of absorbent layer. 
     
     
         7 . The dual sponge according to  claim 1 , wherein the absorbent layer and the abrasive layer are each resilient. 
     
     
         8 . The dual sponge according to  claim 1 , wherein the absorbent layer and the abrasive layer are each flexible. 
     
     
         9 . The dual sponge according with  claim 1 , wherein the abrasive layer is of a woven and/or extruded material. 
     
     
         10 . The dual sponge according to  claim 1 , wherein the abrasive layer is woven. 
     
     
         11 . The dual sponge according to  claim 1 , wherein the abrasive layer is woven with wire which is non-corrosive upon contact with water. 
     
     
         12 . The dual sponge according to  claim 1 , wherein the abrasive layer is flexible. 
     
     
         13 . The dual sponge according to  claim 1 , wherein the abrasive layer is made up of one or more flexible materials comprising at least one of polyethylene terephthalate (PET), polyester, nylon, cotton, rayon, polypropylene, bamboo, and microfiber. 
     
     
         14 . The dual sponge according to  claim 9 , wherein the abrasive layer is a continuous network of nodes that are separated by openings.
