Hydroentangled textile and use in a personal cleansing implement

Abstract

A non-woven hydroentangled textile is described formed in cross-section with a central area of low mass fiber density surrounded on both sides by areas of higher mass density. Further, a personal cleansing article is described wherein the hydroentangled textile is associated with a personal cleansing composition that includes a lathering surfactant. The composition is deposited onto, impregnated into or at least is partially enclosed by the textile. Also described is a process for producing the textile involving feeding into a hydroentangling unit a loose random assembly of fibers both above and below a fibrous screen modifying textile substrate.

1 . A non-woven hydroentangled textile formed in cross-section with a central area of low mass fiber density surrounded on both sides by areas of higher mass fiber density.  
   
   
       2 . The textile according to  claim 1  which cannot be separated into multiple layers after formation without destruction of the textile.  
   
   
       3 . The textile according to  claim 1  wherein the areas of higher mass fiber density on both sides relative to the central area of low mass fiber density have a basis weight ratio ranging from about 10:1 to about 1:2.  
   
   
       4 . The textile according to  claim 3  wherein the ratio ranges from about 6:1 to 1:1.  
   
   
       5 . The textile according to  claim 1  wherein the Air Permeability ranges from about 300 to about 1,000.  
   
   
       6 . A process for the manufacture of a non-woven hydroentangled textile comprising: 
 (i) feeding a fibrous screen modifying textile substrate into a hydroentangling unit;    (ii) feeding a loose random assembly of fibers into the hydroentangling unit, a portion of the assembly of fibers being deposited over and another portion of the assembly of fibers being deposited under the screen modifying textile substrate thereby forming a layered fibrous assembly;    (iii) applying a high velocity water jet to the layered fibrous assembly within the hydroentangling unit; and    (iv) transporting a resultant hydroentangled layered fibrous assembly to a drying area.    
   
   
       7 . A personal cleansing article comprising: 
 a) a non-woven hydroentangled textile formed in cross-section with a central area of low basis weight surrounded on both sides by areas of higher basis weight; and    (b) a personal cleansing composition comprising a lathering surfactant deposited onto, impregnated into or at least being partially enclosed by the textile.    
   
   
       8 . The article according to  claim 7  wherein the lathering surfactant is present in amount from about 0.1 to about 30% by weight of the composition.  
   
   
       9 . The article according to  claim 7  wherein the personal cleansing composition further comprises from about 0.1 to about 35% by weight of a water-soluble or water-insoluble skin conditioning agent.  
   
   
       10 . The article according to  claim 7  wherein the personal cleansing composition further comprises effervescent ingredients capable of generating a foam upon contact with water.  
   
   
       11 . The article according to  claim 7  wherein the effervescent ingredients comprise an acid and a bicarbonate salt.  
   
   
       12 . The article according to  claim 7  wherein the areas of higher basis weight on both sides relative to the central area of low basis weight have a basis weight ratio ranging from about 10:1 to about 2:1.  
   
   
       13 . The article according to  claim 12  wherein the ratio ranges from about 6:1 to 2:1.  
   
   
       14 . The article according to  claim 7  wherein the textile cannot be separated into multiple layers after formation without destruction of the textile.  
   
   
       15 . The article according to  claim 7  wherein the textile has an Air Permeability ranging from about 300 to about 1,000.
