Abstract

Fibrous structures that exhibit improved wet compression properties, and more particularly to wet compression-enhancing agent-containing fibrous structures that provide superior wet compression properties compared to the same fibrous structures without the wet compression-enhancing agent, are provided.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A fibrous structure comprising a wet compression-enhancing agent such that the fibrous structure exhibits at least one of the following properties:
 a. at least one Wet Compression value in a load value range of from 100 g to 300 g during the Compression Portion of the Wet Compression Test Method that is statistically greater than the corresponding Wet Compression value of the same fibrous structure void of the wet compression-enhancing agent as measured according to the Wet Compression Test Method; and   b. at least one Wet Compression value in a load value range of from 50 g to 300 g during the Relaxation Portion of the Wet Compression Test Method that is statistically greater than the corresponding Wet Compression value of the same fibrous structure void of the wet compression-enhancing agent as measured according to the Wet Compression Test Method.   
     
     
         2 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits at least one Wet Compression value in a load value range of from 100 g to 300 g during the Compression Portion of the Wet Compression Test Method that is statistically greater than the corresponding Wet Compression value of the same fibrous structure void of the wet compression-enhancing agent as measured according to the Wet Compression Test Method. 
     
     
         3 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.446 mm at a load value of 300 g during the Compression Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         4 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.543 mm at a load value of 200 g during the Compression Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         5 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.622 mm at a load value of 150 g during the Compression Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         6 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.676 mm at a load value of 125 g during the Compression Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         7 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.742 mm at a load value of 100 g during the Compression Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         8 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.824 mm at a load value of 75 g during the Compression Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         9 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.923 mm at a load value of 50 g during the Compression Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         10 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits at least one Wet Compression value in a load value range of from 50 g to 300 g during the Relaxation Portion of the Wet Compression Test Method that is greater than the corresponding Wet Compression value of the same fibrous structure void of the wet compression-enhancing agent as measured according to the Wet Compression Test Method. 
     
     
         11 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.444 mm at a load value of 300 g during the Relaxation Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         12 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Wet Compression value of greater than 0.452 mm at a load value of 200 g during the Relaxation Portion of the Wet Compression Test Method as measured according to the Wet Compression Test Method. 
     
     
         13 . The fibrous structure according to  claim 1  wherein the wet compression-enhancing agent comprises a polymer. 
     
     
         14 . The fibrous structure according to  claim 13  wherein the polymer comprises a water-soluble polymer. 
     
     
         15 . The fibrous structure according to  claim 13  wherein the polymer comprises a polyacrylamide. 
     
     
         16 . The fibrous structure according to  claim 1  wherein the fibrous structure comprises a plurality of pulp fibers. 
     
     
         17 . The fibrous structure according to  claim 1  wherein the fibrous structure comprises a sanitary tissue product. 
     
     
         18 . The fibrous structure according to  claim 17  wherein the sanitary tissue product comprises a paper towel. 
     
     
         19 . The fibrous structure according to  claim 1  wherein the fibrous structure exhibits a Moisture content of less than 30% by weight of the fibrous structure. 
     
     
         20 . The fibrous structure according to  claim 1  wherein the wet compression-enhancing agent is retained by the fibrous structure during normal use when saturated with distilled water.
