Abstract
Abstract Aqueous warp sizing compositions and the sized yarns obtained by applying the new sizing composition to textile yarn, removing excess composition from the yarn, drying the resulting wet-sized yarn and separating the individual yarns (ends) from one another before or after drying. The novel aqueous sizing composition is a blend of a lubricant, a surfactant, a redispersible latex composition and various optional ingredients. The redispersible latex component comprises a blend of (a) a six-membered carbocyclic compound having two carboxyl substituents and which is soluble in aqueous alkaline media such as the disodium salt of 1,2,3,6-tetrahydrophthalic acid and (b) an aqueous colloidal dispersion of a film-forming carboxyl-containing polymer such as a copolymer of styrene, butadiene and acrylic acid.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
A TEXTILE YARN SIZING COMPOSITION COMPRISING (A) AN AQUEOUS COLLODIAL DISPERSION CONTAINING (1) A FILM-FORMING COPOLYMER OF FROM ABOUT 1 PERCENT TO ABOUT 10 PERCENT OF AN A,BETHYLENICALLY UNSATURATED CARBOXYLIC ACID AND THE BALANCE OF AN ESSENTIALLY WATER-INSOLUBLE, ETHYLENICALLY UNSATURATED MONOMER COMPOSITION AND (2) A SIX-MEMBERED CARBOCYCLIC COMPOUND HAVING TWO VICINAL CARBOXY GROUPS WHICH IS SOLUBLE IN AQUEOUS ALKALINE MEDIA IN AN AMOUNT SUFFICIENT TO PROVIDE REDISPERSIBILITY OF THE COPOLYMER RESIDUE OBTAINED BY DRYING THE AQUEOUS COLLOIDAL DISPERSION AT A PH OF FROM ABOUT 7 TO ABOUT 14 AND (B) A LUBRICANT, SAID SIZING COMPOSITION ALSO CONTAINING FOR ABOUT 0.5 PERCENT TO ABOUT 7 PERCENT, BASED ON THE COPOLYMER WEIGHT, OF A SURFACTANT.
