Abstract

A cellulosic shaped body, for example, a foil or fiber is produced by passing a spinning solution from an orifice into a spinning bath. The ratio of the withdrawal velocity from this spinning bath to the orifice emergence velocity is held at no more than 1 and after emergence from the spinning bath, the body is stretched.
