METHOD AND DEVICE FOR MANUFACTURING SPUNBONDED NONWOVEN FABRIC OF CELLULOSIC FILAMENTS

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a spunbonded nonwoven fabric of cellulosic filaments.

SOLUTION: The method for the manufacture of the spunbonded fabric of cellulosic filaments wherein the filaments are spun from a cellulose solvent 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 processing air, i.e., cooling air of different rate and/or different temperature and/or different humidity.
