Abstract
A cellulosic solution in a amine oxide and water is forced through an elongated orifice passage having a minimum length of 1000 /.mu.m and a minimum diameter along the length which is up to 150 /.mu.m so that fiber characteristics are imparted to the emerging strand which passes through an air gap of at the most 35 mm in length into the coagulating solution.
