Abstract

A method of treating hemp fiber and yarn by partially impregnating the hemp fibers with treating compositions is disclosed. The treating compositions are water-based or organic solvent-based and may contain true soaps, starches, waxes, polyalkalene resins or another chemical that demonstrates the ability to provide the advantages listed herein. The key to the present invention is the partial impregnation of the hemp fibers and yarns, which are also part of the invention.

Claims

exact text as granted — not AI-modified
I claim:  
     
         1 . A method of treating a hemp fiber which comprises moving the fiber through a treating composition such that the fiber becomes partially impregnated with the treating composition.  
     
     
         2 . A method according to  claim 1 , wherein the treating composition is aqueous.  
     
     
         3 . A method according to  claim 1 , wherein the treating composition includes paraffin emulsion.  
     
     
         4 . A method according to  claim 3 , wherein the treating composition includes zirconium ion and acetic acid.  
     
     
         5 . A method according to  claim 1 , wherein the treating composition contains fluorocarbon resin.  
     
     
         6 . A method according to  claim 1 , wherein the treating composition contains isopropyl alcohol and acetic acid.  
     
     
         7 . A method according to  claim 1 , wherein the treating composition includes a true soap.  
     
     
         8 . A method according to  claim 1 , wherein the treating composition contains a polyalkalene resin.  
     
     
         9 . A method according to  claim 1 , wherein the treating composition contains a wax.  
     
     
         10 . A method according to  claim 1 , wherein the treating composition contains polytetrafluoroethylene.  
     
     
         11 . A method according to  claim 1 , wherein the treating composition contains polyethylene.  
     
     
         12 . A method according to  claim 1 , wherein the treating composition contains polypropylene.  
     
     
         13 . A method according to  claim 1 , wherein the treating composition contains a starch.  
     
     
         14 . A method according to  claim 1 , wherein the treating composition is heated.  
     
     
         15 . A method according to  claim 1 , wherein the treating composition contains an organic solvent.  
     
     
         16 . A treated hemp fiber, characterized in that the fiber is partially impregnated with a treating composition.  
     
     
         17 . A treated hemp fiber prepared using the method disclosed in  claim 1.
