Method for the manufacture of a spunbonded fabric of cellulosic filaments wherein the filaments are spun from a cellulose solution using a spinneret. The cellulosic filaments are subsequently introduced into a cooling chamber of at least two cooling sections. In each of the two cooling sections the filaments are brought into contact with process or cooling air of different rate and/or different temperature and/or different humidity.
