Abstract
Emulsion and 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. The emulsions and spin finishes all include a yarn finish composition which comprises (a) a solution of a salt of dioctyl sulfosuccinate, propylene glycol and water, and (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.
