Abstract (en)

[origin: WO2008113481A1] The invention relates to a method for the wet drawing of a steel cable, also called "steelcord", for reinforcing a tyre, that uses, as a lubricant composition, an aqueous dispersion containing solid particles of a fatty acid ester including from 5 to 40 carbon atoms, in particular a diester of the formula R<SUP>1</SUP> - CO - O - A - O - CO - R<SUP>2</SUP>] in which R<SUP>1</SUP> and R<SUP>2</SUP> are hydrocarbon groups including from 5 to 23 carbon atoms, preferably from 13 to 21 carbon atoms. More particularly, the diester is a glycol distearate (EGDS). The use of such a diester, particularly in combination with a surfactant such as a block copolymer of ethylene oxide and C<SUB>3</SUB>-C<SUB>10</SUB> alkylene oxide, results in improved lubrication performance.
