    Abstract: 1,247,758. Treating textiles. MILLMASTER ONYX CORP. 8 July; 1969 [22 July, 1968], No. 34292/69. Heading D1P. Textile materials are rendered antistatic by treatment under acid conditions with an aqueous solution of an agent comprising a water-soluble polytertiary amine of the general formula Y-Z-[N(R)-Z] D -Y 1 where R is an alkyl, alkylene or hydroxyalkyl radical containing from 1 to 22 carbon atoms, preferably methyl, ethyl or hydroxyethyl, Z is a divalent radical derived from a polyglycol by removal of the two hydroxyl radicals, Y represents a tertiary amino radical -NR 3 R 4 where R 3 and R 1 are the same or different alkyl, hydroxyalkyl, aralkyl or alkaralkyl radicals containing from 1 to 10 carbon atoms and Y 1 is a tertiary amino group similar to Y, a secondary amino group -HNR, where R is as above, or the ester forming residue of an inorganic acid or an organically substituted sulphuric, phosphoric or sulphonic acid, e.g. -Cl, -Br, -I, -SO 3 H, SO 3 CH 3 , -SO 4 H, -SO 4 CH 3 , or CH 3 C 6 H 4 SO 3 - p being an integer with a value of at least 1, the material being subsequently dried and the agent cured in situ. The radical Z is preferably of the type -CH 2 CH 2 (-OCH 2 CH 2 ) m OR 2 O (CH 2 CH 2 O-) n CH 2 CH 2 -, in which R 2 is an organic divalent radical and m and n are numbers between 3 and 40, R 2 being either a radical derived from a glycol by removal of its hydroxyl groups, a dibasic acid radical OCACO, or a diurethane radical OCNHANHOO, where A is the intermediate divalent radical of the dibasic acid or diurethane respectively. The polytertiary amine agents may be cured, using a zinc fluoroborate catalyst, either alone or by treatment at elevated temperatures with a polyepoxide cross-linking agent or with ethylene-imino compounds containing a plurality of aziridinyl groups. Other crosslinking agents that may be used include polyethylene glycol di-esters of inorganic or organically substituted inorganic acids. Materials which may be treated include fibres, filament, yarns and knitted, woven, non-woven or felted fabrics of nylon, polyester, acylic, cellulose triacetate, or vinyl chloride-acrylic polymers, or wool, or mixtures thereof.
