Cleansing tissue

Abstract

The present invention is related to a cleansing tissue, comprising a thermobonded non-woven fabric formed from a mixture of fibers containing greater than 75% of thermoplastic fibers, the non-woven fabric having a plurality of cells, each cell having a first density and a first volume, the cells being disposed adjacent to one another defining a region between adjacent cells, the region having a second density and a second volume, the second density being higher than the first density, and the second volume being less than the first volume. The fabric becomes thicker and its softness is increased because the cells have a low density large sized regions.

1 .

         2 . The tissue according to  claim 1 , wherein the cells have a uniform shape, preferably hexagonal.  
     
     
         3 . The tissue according to  claim 1 , wherein the cells are arranged in a honeycomb pattern.  
     
     
         4 . The tissue according to  claim 1 , wherein said non-woven fabric comprises a mixture of thermoplastic fibers and cellulose fibers.  
     
     
         5 . The tissue according to  claim 4 , wherein said thermoplastic fibers are polypropylene fibers and said cellulose fibers are rayon fibers.  
     
     
         6 . The tissue according to  claim 5 , wherein the mixture of polypropylene fibers and rayon fibers preferably has a ratio between the 90%:10% and 80%:20%.  
     
     
         7 . The tissue according to  claim 5 , wherein the polypropylene fiber has a denier index in the range between 0.5 and 5.0.  
     
     
         8 . The tissue according to  claim 7 , wherein the polypropylene fiber has a denier between 0.5 and 4.0.  
     
     
         9 . The tissue according to  claim 7 , wherein the polypropylene fiber has a denier between 0.8 and 1.5.  
     
     
         10 . The tissue according to  claim 5 , wherein the rayon fiber preferably has a denier between 0.5 and 5.0.  
     
     
         11 . The cleansing tissue according to  claim 10 , wherein the rayon fiber preferably has a denier between 0.8 and 3.  
     
     
         12 . The tissue according to  claim 5 , wherein the polypropylene fibers and the rayon fibers have a cut size range between 30 mm and 60 mm.  
     
     
         13 . The tissue according to  claim 1 , wherein its thickness varies between 250 to 800 micrometers.  
     
     
         14 . The tissue according to  claim 1 , wherein said tissue also includes an opacifying agent.  
     
     
         15 . The tissue according to  claim 14 , wherein said opacifying agent is TiO 2 .  
     
     
         16 . The tissue according to  claim 15 , wherein the TiO 2  content in the polypropylene fiber is preferably up to 3%.  
     
     
         17 . The tissue according to  claim 16 , wherein the TiO 2  content in the polypropylene fiber is from 0.5 to 2%.  
     
     
         18 . The tissue according to  claim 17 , wherein the TiO 2  content in the rayon fiber is preferably from 0.5 to 1.5%.
