Abstract

A process for making bulky elastic texturized acetate yarn having good elasticity, good tensile strength and good durability of elasticity and tensile strength in washing and dry cleaning which comprises applying to acetate yarn a curable synthetic resin, applying to said acetate yarn a twist wet heat setting agent, bulking and texturizing said acetate yarn by imparting a false twist thereto, heating said yarn to twist wet heat set said false twist, dissolve twisting said yarn, drying said acetate yarn and heat treating said dried acetate yarn to cure said curable synthetic resin therein, and bulky elastic texturized acetate yarn so made.
