Abstract
Textile yarns are treated with a sizing composition which, when dried and cured, remains durably bound to the yarn throughout wet finishing operations and subsequent use. The sizing composition comprises an aqueous self-crosslinking emulsion copolymer derived from at least one ethylenically unsaturated monomer and a latent-crosslinking monomer. The sizing composition may also include a water soluble or dispersible film forming polymer and a reactive resin. The durable size coating beneficially contributes to both the physical and the aesthetic properties of the yarn and fabrics formed therefrom.
