Ormand, Upson County, Ga., assignor to Thomaston Cotton Mills, Thomaston, Ga., a corporation of Georgia Filed Mar. 26, 1963, Ser. No. 267, 932 5 Claims. (Cl. 28-74) This invention relates to woven fabrics comprising blends of cotton and synthetic fibers having recoverable stretch characteristics, and is particularly directed to the production of cotton-polyester blend fabrics woven from standard or normal twist yarns which have desirable stretch properties in the filling direction.

A primary object of the invention is to provide a simple but elfective process for manufacturing woven cottonpolyester blend fabrics whereby stabilized width stretch characteristics are embodied therein by a novelcombination of mechanical and chemical treating steps Without using stretch or textured yarns, and without requiring special machinery.

Another object is the provision of a new and economical method for producing fabrics woven of cotton and polyester fibers having high stretch and recovery properties in the filling direction wherein only standard or normal twist yarns are employed.

A further object is to produce woven cotton-synthetic blend fabrics of improved stretch characteristics which.

are especially well adapted for end use in the apparel field, for such items as shirts, pajamas, brassiere fabrics, outerwear, underwear, lounge wear, sportswear, foundation garments, shoes, bathing suits and coating for rainwear, and for such industrial end uses as the manufacture of vinyl, rubber, pyroxylin and polyurethane coated or laminated textile materials, where resiliency in one direction is-an important consumer quality.
