ABSTRACT:
A process for producing a regenerated cellulose fiber having a good hand and a good shrink resistance characterized by attaching a liquid not readily soluble in liquid ammonia and adsorbable on regenerated cellulose fiber to the surface of regenerated cellulose fiber or attaching a polymer to the surface of regenerated cellulose fiber in the form of a film or not carrying out the surface treatment mentioned above, and adjusting the moisture content of said regenerated cellulose fiber to 5% or more based on the absolute dry weight of said fiber, and thereafter impregnating said regenerated cellulose fiber with liquid ammonia, and subsequently removing the ammonia from the regenerated cellulose fiber.
