Abstract
Several spin finishes are disclosed for incorporation with synthetic organic polymer yarn or yarn products to render the same oil repellent and resistant to soiling. All of the spin finishes include a yarn finish composition which comprises (a) a nonhomogeneous mixture of a salt of dinonyl sulfosuccinate, a salt of dimethyl naphthalene sulfonate, and ammonium perfluoroalkyl carboxylate, 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.
