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.

A spin finish for yarn, made from synthetic organic polymer, to be processed at high temperature into a yarn that is oil repellent and resistant to soiling, said spin finish comprising: a. about 5 to 25 percent by weight of said spin finish of a first noncontinuous phase consisting essentially of i. about 15 to 80 weight percent of a nonhomogeneous mixture of a salt of dinonyl sulfosuccinate, a salt of dimethyl naphthalene sulfonate, and ammonium perfluoroalkyl carboxylate, and ii. about 20 to 85 weight percent of a fluorochemical compound having the formula [Figure] wherein the attachment of the fluorinated radicals and the radicals CO2B to the nucleus is in asymmetrical positions with respect to rotation about the axis through the center of the nucleus; wherein “X”is fluorine, or perfluoroalkoxy of 1 to 6 carbon atoms, and m has arithmetic mean between 2 and 20; n is zero or unity; “W”and “Y”are alkylene, cycloalkylene or alkyleneoxy radicals of combined chain length from 2 to 20 atoms; (CF2)m and “Y”have each at least 2 carbon atoms in the main chain; “Z”is oxygen and p is 1, or “Z”is nitrogen and p is 2; q is an integer of at least 2 but not greater than 5; “B”is CH2RCHOH or is CH2RCHOCH2RCHOH where “R”is hydrogen or methyl, or “B”is CH2CH(OH)CH2Q where Q is halogen, hydroxy, or nitrile; or “B”is CH2CH(OH)CH2OCH2CH(OH)CH2Q; and r is an integer of at least 1 but not greater than q; and X(CF)2)m, W and Y are straight chains, branched chains or cyclic; and wherein the substituent chains of the above general formulas are the same or different; b. about 50 to 90 percent by weight of said spin finish of water; and c. about 5 to 25 percent by weight of said spin finish of a second noncontinuous phase which is capable of being emulsified with said first noncontinuous phase and said water without separation of any of the component parts of said spin finish.
