APPARATUS FOR PRODUCING SPUN-BONDED NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a production apparatus capable of spinning two kinds of filament components having different sizes and melting points while increasing the treating amount per unit area. SOLUTION: Each rectangle or circular spinning nozzle package used for spinning a thermoplastic filament comprises a molten matter channel 12 and extrusion bores 8 for polymer compound with the high melting point, and a molten matter channel 13 and extrusion bores 7 for passing a polymer compound having a melting point 5-50 deg.C lower than that of the polymer compound with the high melting point, respectively. Insulating caves 10 and 11 with various structures thermally isolate these molten matter channels used in different temperatures.
