         4 . A method of use according to any of  claims 1  to  3 , wherein the compound of formula (1) is applied to the textile material as aqueous formulation in diluted, solubilised, emulsified or dispersed form.  
     
     
         5 . A method of use according to any of  claims 1  to  4 , wherein the compound of formula (1) is dispersed with at least one dispersant selected from the group consisting of acid esters or their salts of alkylene oxide adducts; polystyrene sulfonates; fatty acid taurides; alkylated diphenyl oxide mono- or disulfonates; sulfonates of polycarboxylates; the polyadducts of 1 to 60 mol of ethylene oxide and/or propylene oxide with fatty amines, fatty acids or fatty alcohols, each containing 8 to 22 carbon atoms in the alkyl chain, with alkylphenols containing 4 to 16 carbon atoms in the alkyl chain, or with trihydric to hexahydric alkanols containing 3 to 6 carbon atoms, which polyadducts are converted into an acid ester with an organic dicarboxylic acid or with an inorganic polybasic acid; ligninsulfonates; and formaldehyde condensates.  
     
     
         6 . A method of use according to any of  claims 1  to  5 , wherein the compound of formula (1) is dispersed with at least one dispersant selected from the group consisting of condensates of ligninsulfonates and/or phenol and formaldehyde; condensates of formaldehyde with aromatic sulfonic acids; condensates of naphthalenesulfonic acid and/or naphthol- or naphthylaminesulfonic acids with formaldehyde; condensates of phenolsulfonic acids and/or sulfonated dihydroxydiphenylsulfone and phenols or cresols with formaldehyde and/or urea; and condensates of diphenyl oxide-disulfonic acid derivatives with formaldehyde.  
     
     
         7 . A method of use according to any of  claims 1  to  6 , wherein the compound of formula (1) is applied to the textile material by padding and wherein said textile material is continuously passed through an aqueous liquor containing 0.001% to 10% by weight, based on the weight of the aqueous liquor, of the compound of formula (1).  
     
     
         8 . A method of use according to any of  claims 1  to  6 , wherein the compound of formula (1) is applied to the textile material by spraying, wherein an aqueous liquor containing 0.001% to 10% by weight, based on the weight of the aqueous liquor, of the compound of formula (1) is sprayed onto the textile material.  
     
     
         9 . A method of use according to any of  claims 1  to  6 , wherein the compound of formula (1) is applied to the textile material by foam application, wherein an aqueous foam containing 0.001% to 10% by weight, based on the weight of the aqueous foam, of a compound of formula (1) and optionally a foam stabiliser is applied to the textile material.  
     
     
         10 . A method of use according to any of claims  1  and  4  to  6 , wherein the compound of formula (1) is applied to the textile material during a dry cleaning process, wherein the textile material is treated with an organic solvent, preferably perchloroethylene or trichloroethylene, containing 0.001% to 10% by weight, based on the weight of the organic solvent, of a compound of formula (1).  
     
     
         11 . A method of use according to any of  claims 1  to  10 , wherein the textile material is selected from natural or synthetic polyamide, polyurethane, polyester, polypropylene, polyethylene, polyacrylonitrile and cellulose-containing textile materials.  
     
     
         12 . A method of us according to any of  claims 1  to  11 , wherein the textile material is selected from wool, synthetic polyamide, polyester, polypropylene, polyethylene and cellulose-containing textile materials, preferably cotton or wool.  
     
     
         13 . A method of use according to any of  claims 1  to  12 , wherein the textile material is a nonwoven textile material or a carpet, preferably a carpet.  
     
     
         14 . A method of use for the treatment of polyacrylonitrile fibres to improve the antifungal and/or antidustmite properties, comprising applying to said fibres in the gel state a compound of formula
