Apparatus for carrying out the method to take winding stretched melt spinning a multifilament yarn, as well as how to take turns stretched melt spinning a multifilament yarn

摘要

The present invention relates to a method and to apparatus for carrying out the method of forming the melt spun multifilament yarn stretched winding FDY yarns. First, a large number of filaments extruded from a thermoplastic melt, cooled to a temperature below the glass transition temperature of the thermoplastic material, preparation process oils having 8% water content at maximum is supplied, the filaments are combined , the filament bundle is formed. Then, by multiplying wound partially filament bundle singlet in the guide covering body which is selectively heated in a driven godet roller, the filament bundle is drawn off in take-off speed in excess of 1200 m / min. To stretched then relaxed, filament bundle, at a stretching speed of more than 3500 m / min, it is guided partially wound around the singlet around another guide covering member which is heated in the driven godet roller. Device according to the invention for this purpose comprises two godet group having a plurality of godet rollers of the driven, the first godet group, a filament bundle, partially around the singlet to receipt and / or heating over and guide, the second godet group, the filament bundles, to guide partially wrapped around the singlet to stretching.
