Filament coherency enhancing composition and textile yarns coated therewith

Claim 1

A substantially homogeneous aqueous composition for use in imparting coherency to textile filaments, comprising an emulsifiable textile finishing oil and water dissipatable polymer at a weight ratio of from about 19/1 to about 5/1 and water comprising from about 90 to about 70 wt. % of the total composition wherein said water dissipatable polymer comprises the reaction products of (a), (b), (c) and (d) from the following components or ester forming or esteramide forming derivatives thereof: (a) at least one difunctional dicarboxylic acid; (b) from about 4 to about 25 hole percent based on a total of all acid, hydroxyl and amino equivalents being equal to 200 mole percent, of at least one difunctional sulfomonomer containing at least one metal sulfonate group attached to aromatic nucleus wherein the functional groups are hydroxy, carboxyl or amino; (c) at least one difunctional reactant selected from a glycol or a mixture of a glycol and diamine having two --NRH groups, the glycol containing two --CH.sub.2 --OH groups of which at least 15 mole percent based on the total mole percent of hydroxy or hydroxy and amino equivalents, is a poly(ethylene glycol) having the structural formula: H(OCH.sub.2 --CH.sub.2).sub.n OH n being an integer of between 2 and about 20; and (d) from none to at least one difunctional reactant selected from a hydroxycarboxylic acid having one --CH 2 --OH, an aminocarboxylic acid having one --NRH group, an amino-alcohol having one --CR.sub.2 --OH group and one --NRH or mixtures thereof, and wherein each R is an H atom or an alkyl group of 1 to 4 carbon atoms.
