<p>#CMT# #/CMT# The method for producing spunbonded fabrics from thermoplastic continuous filaments, comprises producing the continuous filaments from plastic blend, extruding the filaments from a spinning nozzle, and subsequently cooling the filaments in a cooling chamber (2) by supplying cool air and then aerodynamically drawing in a drawing unit (5). No further external air is supplied in the aggregate from the cooling chamber and the drawing unit except the supplied cool air. The drawing conditions are adjusted with the proviso during the aerodynamical drawing. #CMT# : #/CMT# The method for producing spunbonded fabrics from thermoplastic continuous filaments, comprises producing the continuous filaments from plastic blend, extruding the filaments from a spinning nozzle, and subsequently cooling the filaments in a cooling chamber (2) by supplying cool air and then aerodynamically drawing in a drawing unit (5). No further external air is supplied in the aggregate from the cooling chamber and the drawing unit except the supplied cool air. The drawing conditions are adjusted with the proviso during the aerodynamical drawing. The filaments are obtained with a titer of less than 0.8 and are discarded on a tray to the spunbonded fabrics after the aerodynamical drawing. #CMT#USE : #/CMT# Method for producing spunbonded fabrics from thermoplastic continuous filaments. #CMT#ADVANTAGE : #/CMT# The method ensures safe, economical, simple and continuous production of the spunbonded fabrics with high quality in easier manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a vertical section of a device for producing plastic-filaments. 2 : Cooling chamber 3, 4 : Sections of the cooling chamber 5 : Drawing unit 6 : Intermediate channel 8, 9 : Diffusers. #CMT#POLYMERS : #/CMT# Preferred Components: The plastic blend contains first polypropylene with a melt flow index (MFI) of 20-70 g/10 minutes and second polypropylene with a melt flow index of 300-3000 g/10 minutes.</p> |
