Method for providing textile material with uv protection

Abstract

A method for UV protecting a textile material which comprises applying (a) zinc oxide and/or titanium oxide as a component A and (b) one or more organic UV absorbers as a component B to said textile material. Component B preferably comprises one or more compounds selected from the group consisting of phenylbenzotriazoles, dibenzoylmethanes, esters of p-aminobenzoic acid, esters of cinnamic acid, esters of salicylic acid, nonnitrogenous 2-hydroxybenzophenones, phenylbenzimidazoles, acrylates, diarylbutadienes, amino-substituted hydroxybenzophenones, triazines.+

We claim:  
     
         1 . A method for UV protecting a textile material, which comprises applying 
 (a) zinc oxide and/or titanium oxide as a component A and    (b) one or more organic UV absorbers as a component B to said textile material.    
     
     
         2 . A method as claimed in  claim 1 , wherein said component A comprises UV absorbers having an absorption maximum in the range from 280 to 450 nm.  
     
     
         3 . A method as claimed in  claim 1  or  2 , wherein said component B comprises one or more compounds selected from the group consisting of 
 phenylbenzotriazoles,  
 dibenzoylmethanes,  
 esters of p-aminobenzoic acid,  
 esters of cinnamic acid,  
 esters of salicylic acid,  
 nonnitrogenous 2-hydroxybenzophenones,  
 phenylbenzimidazoles,  
 acrylates,  
 diarylbutadienes,  
 amino-substituted hydroxybenzophenones,  
 triazines.  
 
     
     
         4 . A method as claimed in any of  claims 1  to  3 , wherein the weight ratio of said component A to said component B is in the range from 20:1 to 1:10.  
     
     
         5 . A method as claimed in any of  claims 1  to  4 , wherein said components A and B are applied to said textile material in the form of an aqueous liquor containing said components A and B alongside further ingredients.  
     
     
         6 . A method as claimed in any of  claims 1  to  5 , wherein said components A and B are applied to said textile material in the course of textile finishing during the manufacture of said textile material, in the course of laundering and/or in the course of laundry aftertreatment.  
     
     
         7 . A laundry detergent formulation comprising from 0.01 to 20% by weight, based on their total, of said components A and B as defined in any of  claims 1  to  4  as well as further customary constituents.  
     
     
         8 . A laundry aftertreatment and laundry conditioning formulation comprising from 0.01 to 20% by weight, based on their total, of said components A and B as defined in any of  claims 1  to  4  as well as further customary constituents.  
     
     
         9 . A laundry aftertreatment and laundry conditioning formulation as claimed in  claim 8 , comprising from 1 to 50% by weight of one or more cationic surfactants selected from the group consisting of quaternary diesterammonium salts, quaternary tetraalkylammonium salts, quaternary diamidoammonium salts, amidoamino esters and imidazolines.  
     
     
         10 . A finishing composition for UV protecting a textile material, comprising a mixture of said components A and B as defined in any of  claims 1  to  4 .  
     
     
         11 . Textile material comprising a mixture of said components A and B as defined in any of  claims 1  to  4 .  
     
     
         12 . The use of zinc oxide and/or titanium dioxide together with organic UV absorbers on textile material to protect the human skin against harmful UV radiation and/or to protect dyed textile material against fading.
