METHOD AND DEVICE FOR RECOVERING BULK OF NONWOVEN FABRIC

摘要

The present invention provides excellent recovery of bulk in nonwoven fabric. While nonwoven fabric (F) is transported so as to enter a heating chamber (3g) via an entry opening (3gi) and, after progressing within the heating chamber (3g), exit the heating chamber (3g) via an exit opening (3go), heated air is supplied at a speed higher than the transport speed for the unwoven fabric (F) so as to enter the heating chamber (3g) via the entry opening (3gi) and, after progressing within the heating chamber (3g) while contacting the nonwoven fabric (F), exit the heating chamber (3g) via the exit opening (3go).
