Compositions for spray bleaching cellulosic fabrics

Abstract

A composition is provided for spray bleaching cellulosic fabrics. The composition comprises a wetter, hydrogen peroxide, a caustic, a stabilizer, an optical brightener, and water. When the composition is sprayed onto the surfaces of the cellulosic fabric, it achieves penetration into the fabric so that a uniform whiteness is achieved throughout the fabric.

1 . A composition for spray bleaching cellulosic fabrics, comprising:
 (a) a wetter;   (b) hydrogen peroxide;   (c) a caustic;   (d) a stabilizer;   (e) an optical brightener; and   (f) water.   
     
     
         2 . The composition of  claim 1 , wherein the wetter comprises a surfactant. 
     
     
         3 . The composition of  claim 2 , wherein the surfactant comprises between about 16 g/l and 32 g/l of the composition. 
     
     
         4 . The composition of  claim 1  wherein the hydrogen peroxide comprises between about 20 g/l and 250 g/l of the composition. 
     
     
         5 . The composition of  claim 1 , wherein the caustic is sodium hydroxide. 
     
     
         6 . The composition of  claim 5 , wherein sodium hydroxide comprises between about 10 g/l and 150 g/l of the composition. 
     
     
         7 . The composition of  claim 1 , wherein the stabilizer is an organophosphorus compound. 
     
     
         8 . The composition of  claim 7 , wherein the organophosphorus compound comprises between about 5 g/l and 50 g/l of the composition. 
     
     
         9 . The composition of  claim 1 , wherein the optical brightener is a distyryl biphenyl compound. 
     
     
         10 . The composition of  claim 9 , wherein the distyryl biphenyl compound comprises between about 1 g/l and 20 g/l of the composition. 
     
     
         11 . The composition of  claim 1 , further comprising a chelator. 
     
     
         12 . The composition of  claim 11 , wherein the chelator is a softener. 
     
     
         13 . The composition of  claim 1 , further comprising a silicate. 
     
     
         14 . The composition of  claim 13 , wherein the silicate is sodium silicate. 
     
     
         15 . The composition of  claim 14 , wherein the sodium silicate comprises between about 10 g/l and 90 g/l of the composition. 
     
     
         16 . A composition for spray bleaching cellulosic fabrics, comprising:
 (a) a wetter comprising between about 16 g/l and 32 g/l;   (b) hydrogen peroxide comprising between about 20 g/l and 250 g/l;   (c) a caustic comprising between about 10 g/l and 150 g/l;   (d) a stabilizer comprising 5 g/l and 50 g/l;   (e) an optical brightener comprising between about 1 g/l and 20 g/l; and   (f) water.
