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 solution of a salt of dioctyl sulfosuccinate, propylene glycol and water, (b) a fluorochemical compound consisting of polycarboxybenzene esterified with certain partially fluorinated alcohols and with hydroxyl-containing organic radicals such as 2-hydroxyethyl, glyceryl, and chlorohydryl or bromohydryl, and (c) a dispersant selected from the group consisting of a salt of a polycarboxylic acid, a salt of a sulfonated naphthalene-formaldehyde condensate, and a salt of an alkyl naphthalene sulfonate.
