Flame retarded textile and process for coating textile

Abstract

The present invention relates to solid phosphate ester, which can be used as a flame retardant in treatments for textile substrates. More specifically, the treatments for textiles substrates can be used as flame retardant formulations for application on textile fabrics while substantially maintaining the desired characteristics (aesthetic or textural properties) of the textile. The present invention thus further provides for articles having these phosphate ester formulations applied thereon, and of processes of applying them onto various textile substrates.

1 . A textile comprising a flame retardant effective amount of a flame retardant additive composition comprising a phosphate ester of the general formula (I): 
       
         
           
           
               
               
           
         
       
       wherein R 1 , R 2 , R 3  and R 4  each independently is aryl, or arylalkyl each independently containing up to about 30 carbon atoms, optionally interrupted with heteroatoms, X is a divalent aryl or arylalkyl group, containing up to about 20 carbon atoms, and n has an average value of from about 1.0 to about 2.0. 
     
     
         2 . The textile of  claim 1  wherein each of R 1 , R 2 , R 3  and R 4  are phenyl, X is a divalent phenylene group, and n is one. 
     
     
         3 . The textile of  claim 1 , wherein the textile which contains the flame retardant additive composition passes the NFPA 701 and MVSS 302 tests. 
     
     
         4 . A process comprising applying a flame retardant effective amount of a flame retardant additive composition comprising a phosphate ester of the general formula (I): 
       
         
           
           
               
               
           
         
       
       wherein R 1 , R 2 , R 3  and R 4  each independently is aryl, or arylalkyl each independently containing up to about 30 carbon atoms, optionally interrupted with heteroatoms, X is a divalent aryl or arylalkyl group, containing up to about 20 carbon atoms, and n has an average value of from about 1.0 to about 2.0, to a textile substrate. 
     
     
         5 . The process of  claim 4  wherein each of R 1 , R 2 , R 3  and R 4  are phenyl, X is a divalent phenylene group, and n is one. 
     
     
         6 . The process of  claim 4  wherein the step of applying comprises contacting the textile substrate with the flame retardant additive composition comprising the phosphate ester (I). 
     
     
         7 . The process of  claim 4  wherein the step of applying comprises backcoating the textile substrate with the flame retardant additive composition comprising the phosphate ester (I). 
     
     
         8 . The process of  claim 4  wherein the step of applying comprises immersing the textile substrate in a flame retardant additive composition comprising the phosphate ester (I). 
     
     
         9 . The process of  claim 6 , further comprising, subsequent to said contacting, heating the textile substrate. 
     
     
         10 . An article comprising the textile of  claim 1 . 
     
     
         11 . The article of  claim 10  wherein the article is selected from the group consisting of furniture, a drapery, a garment, linen, a mattress, a carpet, a tent, a sleeping bag, a toy, a decorative fabric, an upholstery, a wall fabric, a curtain, carpeting, a technical textile and combinations thereof. 
     
     
         12 . A dispersion of a flame retardant additive composition comprising a phosphate ester of the general formula (I): 
       
         
           
           
               
               
           
         
       
       wherein R 1 , R 2 , R 3  and R 4  each independently is aryl, or arylalkyl each independently containing up to about 30 carbon atoms, optionally interrupted with heteroatoms, X is a divalent aryl or arylalkyl group, containing up to about 20 carbon atoms, and n has an average value of from about 1.0 to about 2.0; and, water. 
     
     
         13 . A process of treating a textile comprising applying the dispersion of  claim 12  to a textile substrate. 
     
     
         14 . A textile that has been treated by the process of  claim 13 . 
     
     
         15 . An article comprising the textile of  claim 14 . 
     
     
         16 . The article of  claim 15  wherein the article is selected from the group consisting of furniture, a drapery, a garment, linen, a mattress, a carpet, a tent, a sleeping bag, a toy, a decorative fabric, an upholstery, a wall fabric, a curtain, carpeting, a technical textile and combinations thereof.
