ABSTRACT OF THE DISCLOSURE: There are disclosed processes for preparing a textile treated with a water-insoluble polyester wherein a linear or branched chain water-soluble phos- phate group containing polyester is coated or impreg- nated onto a textile substrate in combination with a cross- linking agent and subsequent to heating to co-react the crosslinking agent with the polyester, the treated tex- tile substrate is exposed to an aqueous solution of a polyvalent metal ion reactive with said phosphate groups in said polyester. Alternatively, there are disclosed pro- cesses for preparing a water-insoluble polyester on a textile substrate wherein a branched chain polyester having phosphate groups is coated or impregnated onto a textile substrate, the substrate is dried and subse- quently exposed to an aqueous solution of a polyvalent metal ion reactive with said phosphate groups in said polyester. The processes disclosed herein are useful in the preparation of nonwoven fabrics and finished woven fabrics such as sized fabrics including use as a pigment binder in sizing woven fabrics.
