Abstract

The present disclosure describes a method of manufacturing a natural textile with water repellent properties. Treatment of a natural textile with a composition of the invention provides water repellency to the treated textile.

Claims

exact text as granted — not AI-modified

What is claimed is: 
     
         1 . A method of manufacturing comprising:
 treating a textile with a composition, the composition comprising:
 (1) polytetrafluoroethylene; and 
 (2) a dendrimer. 
   
     
     
         2 . The method of  claim 1 , wherein the dendrimer is hyperbranched. 
     
     
         3 . The method of  claim 2 , wherein the hyperbranched dendrimer is a hyperbranched polyurethane dendrimer. 
     
     
         4 . The method of  claim 1 , wherein the composition further comprises a comb polymer. 
     
     
         5 . The method of  claim 1 , wherein the composition further comprises an emulsifier. 
     
     
         6 . The method of  claim 1 , wherein the textile is a cotton or a wool. 
     
     
         7 . The method of  claim 1 , wherein the textile is selected from a group consisting of a yarn, a blend, a fabric, a garment, an upholstery, or combinations thereof. 
     
     
         8 . The method of  claim 1 , wherein the treatment is performed with a sprayer. 
     
     
         9 . The method of  claim 1 , wherein the treatment is performed by a dyeing machine or a rolling drum dyeing machine. 
     
     
         10 . The method of  claim 1 , further comprising treating the textile with a booster polymer prior to treating the textile with the composition. 
     
     
         11 . The method of  claim 1 , further comprising, after treating and drying of the textile:
 treating of the textile with a wetting agent;   additional treating of the textile with the composition; and   additional drying of the textile.   
     
     
         12 . A treated textile comprising:
 a textile and a composition comprising:
 polytetrafluoroethylene; and 
 a dendrimer. 
   
     
     
         13 . The treated textile of  claim 12 , wherein the dendrimer is hyperbranched. 
     
     
         14 . The treated textile of  claim 13 , wherein the hyperbranched dendrimer is a hyperbranched polyurethane dendrimer. 
     
     
         15 . The treated textile of  claim 12 , wherein the composition further comprises a comb polymer. 
     
     
         16 . The treated textile of  claim 12 , wherein the comb polymer is modified with a wax. 
     
     
         17 . The treated textile of  claim 12 , wherein the composition further comprises an emulsifier. 
     
     
         18 . The treated textile of  claim 12 , wherein the textile is a cotton or a wool. 
     
     
         19 . The treated textile of  claim 12 , wherein the textile is selected from a group consisting of a yarn, a blend, a fabric, a garment, an upholstery, or combinations thereof. 
     
     
         20 . A treated textile treated with a composition comprising:
 polytetrafluoroethylene;   a dendrimer;   a comb polymer; and   an emulsifier.
