Abstract

The present invention relates to methods for dyeing fibers which comprises adding to the fibers an effective amount for the purpose of a composition including an alkyl lactate and additional components. The present invention further relates to a dyeing composition, comprising (a) a cationic monomer, (b) an alkyl lactate and (c) a zeolite.

Claims

exact text as granted — not AI-modified
1 . A dyeing composition comprising: (a) a cationic compound; (b) an alkyl lactate; and (c) a zeolite.  
   
   
       2 . The composition as recited in  claim 1 , wherein the cationic compound is a quaternary ammonium compound.  
   
   
       3 . The composition as recited in  claim 1 , wherein the alkyl lactate is ethyl lactate.  
   
   
       4 . The composition as recited in  claim 2 , wherein the quaternary ammonium compound is 3-chloro-2-hydroxypropyltrimethylammonium chloride.  
   
   
       5 . The composition as recited in  claim 1 , further comprising (d) methyl bis (canola amidoethyl)-2-hydroxethyl ammonium methyl sulfate.  
   
   
       6 . A method for dyeing nylon or wool fibers which comprises adding to the fibers an effective amount for dyeing of a composition comprising (a) an alkyl lactate; (b) lactic acid, and (c) methyl bis (canola amidoethyl)-2-hydroxethyl ammonium methyl sulfate.  
   
   
       7 . The method as recited in  claim 6 , wherein the alkyl lactate is ethyl lactate.  
   
   
       8 . (canceled)  
   
   
       9 . A method for dyeing cellulosic fibers which comprises adding to the fibers an effective amount for the purpose of a composition comprising (a) a cationic compound; (b) an alkyl lactate; and (c) a zeolite.  
   
   
       10 . The method as recited in  claim 9 , wherein the cationic compound is a quaternary ammonium compound.  
   
   
       11 . The method as recited in  claim 9 , wherein the alkyl lactate is ethyl lactate.  
   
   
       12 . The method as recited in  claim 10 , wherein the quaternary ammonium compound is 3-chloro-2-hydroxypropyltrimethylammonium chloride.  
   
   
       13 . The method as recited in  claim 9 , wherein the composition further comprises (d) methyl bis (canola amidoethyl)-2-hydroxethyl ammonium methyl sulfate.
