ABSTRACT:
A polyester size composition for synthetic fibers useful in protecting the fibers from abrasion during the weaving process or to improve the adhesion to the fibers of conventional size compositions and especially useful with polyester fibers such as those based upon polyethylene terephthalate, comprises a branched water-dispersible polyester which is the reaction product of at least one polycarboxylic acid, at least one diol or polyglycol and an aromatic carboxylic acid containing a --SO.sub.3 M grouping which is attached to the aromatic nucleus of said carboxylic acid through an aliphatic chain and ester linkage and wherein said linkage contains about 2 to about 8 carbon atoms.
