Title: Process for the prevention of electrostatic charging of textile materials and foils
IPC: D06M15/39
Filed: 1960-01-14
Abstract: Compositions which may be applied to textile materials and foils and then hardened comprise a condensation product of (1) an aminotriazine or a derivative thereof, an aldehyde or ketone and an addition product of an alkylene oxide with a compound possessing a replaceable hydrogen atom attached to an oxygen, sulphur or nitrogen atom, (2) a urea-glyoxal condensate which contains alkylol groups or a reaction product of urea, glyoxal and an aldehyde or ketone and a polyalkylene oxide or (3) a urea-glyoxal condensate which contains alkylol groups or a reaction product of urea, glyoxal and an aldehyde or ketone and an addition product of an alkylene oxide with a compound possessing a replaceable hydrogen atom attached to an oxygen, sulphur or nitrogen atom.  Suitable alkylene oxide addition products are those obtained by the reaction of 3-100 mols. of ethylene oxide with 1 mol. of ammonia or a mono- or polyhydric alcohol, phenol, alkyl phenol, mono- or polyvalent carboxylic acid amide, mono- or polyvalent alkylamine, mono- or polyvalent carboxylic acid, alkylolamine, fatty acid alkylolamide or fatty acid trialkylolamine ester, the aliphatic, cycloaliphatic, aromatic or aliphaticaromatic radicals of which contain 1-30 carbon atoms. Suitable condensation products of urea and glyoxal alone which contain alkylol groups or condensation products of urea, glyoxal and an aldehyde or ketone are tetramethylol glycol urea, tetrahydroxy diethylene urea, methylol compounds of dihydroxyethylene urea and the reaction product of 1 mol. of dimethylol urea, 1 mol. of monomethylol urea and 2 mols. of glyoxal. The composition may also contain as hardening catalyst ammonium nitrate, aluminium chloride or magnesium chloride.ALSO:Textile materials and foils made from polyamides, polyesters, polyvinyl compounds or cellulose acetate having an improved resistance to the formation of electrostatic charges thereon are produced by forming in and/or on the surface thereof a hardened condensation product of (1) an aminotriazine or a derivative thereof, an aldehyde or ketone and an addition product of an alkylene oxide with a compound possessing a replaceable hydrogen atom attached to an oxygen, sulphur or nitrogen atom, (2) a urea-glyoxal condensate which contains alkylol groups or a reaction product of urea, glyoxal and an aldehyde or ketone and a polyalkylene oxide or (3) a urea-glyoxal condensate which contains alkylol groups or a reaction product of urea, glyoxal and an aldehyde or ketone and an addition product of an alkylene oxide with a compound possessing a replaceable hydrogen atom attached to an oxygen, sulphur or nitrogen atom.  Suitable alkylene oxide addition products are those obtained by the reaction of 3-100 mols of ethylene oxide with 1 mol of ammonia or a monoor polyhydric alcohol, phenol, alkyl phenol, mono- or polyvalent carboxylic acid, monoor polyvalent carboxylic acid amide, monoor polyvalent alkylamine, alkylolamine, fatty acid alkylolamide or fatty acid trialkylolamine ester, the aliphatic, cycloaliphatic, aromatic or aliphatic-aromatic radicals of which contain 1-30 carbon atoms.  Suitable condensation products of urea and glyoxal alone which contain alkylol groups or condensation products of urea, glyoxal and an aldehyde or ketone are tetramethylol glycol uril, tetrahydroxydiethylene urea, methylol compounds of dihydroxyethylene urea and the reaction product of 1 mol of dimethylol urea, 1 mol of mono methylol urea and 2 mols of glyoxal. Example 11 refers to the treatment of polyamide carpet yarn.
