ABSTRACT:
Modified rayon is produced by adding a modifier to a cellulose solution and spinning fibers from the solution, or by adding a modifier to an alkali cellulose solution or material, xanthating and spinning fibers by the viscose spinning process, wherein the modifier is an amine of the formula (1a), (1b), (1c), (1d) or (1e) ##STR1## The modified rayon produced in this way can be dyed with reactive dyes without addition of electrolyte salt or alkali and have significantly more affinity than conventional viscose fibers.
