Warp-sizing compositions and yarns sized therewith

摘要

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.
