Abstract
A yarn finish composition is disclosed for incorporation with synthetic organic polymer yarn or yarn products to render the same oil repellent and resistant to soiling. The composition comprises (a) a quaternary ammonium salt selected from the group consisting of trialkyl dodecyl ammonium salt and cocotrialkyl ammonium salt, wherein the alkyl is methyl or ethyl and the anion is selected from the group consisting of chloride, bromide, iodide, sulfate, ethosulfate, methosulfate and mixtures thereof, and (b) a fluorochemical compound consisting of polycarboxybenzene esterified with certain partially fluorinated alcohols and with hydroxy-containing organic radicals such as 2-hydroxyethyl, glyceryl, and chlorohydryl or bromohydryl.
