Abstract

Washing methods of deinking secondary cellulose fiber (i.e., removing unwanted non-cellulose materials therefrom) involve deinking the fiber with surface-active agent comprising: an oxyethylene glycol chain, wherein one terminal hydroxyl of the chain has been replaced with an ether group selected from an aliphatic ether group and an alkylaromatic ether group, and the other terminal hydroxyl of the chain has been replaced with an ether group selected from a polyoxypropylene group and a benzyl ether group. The present washing method of deinking reduces or eliminates objectionable foam, potentially provides energy savings yet maintains or improves the quality of the deinked fiber.
