Process for the manufacture of filament yarn having protruding filament ends |
摘要 |
A process is provided for the manufacture of filament yarn having protruding filament ends on the basis of synthetic high polymers by melt spinning of the polymers through spinning nozzles, which comprises subjecting the multifilaments still hot after having left the spinning nozzle to a section cooling which causes determined sections of the single filaments to have a different molecular structure, and by subsequently drawing the filaments in a ratio which is greater than corresponding to those filament sections having a lower drawing ratio, and smaller than corresponding to those filament sections having a higher drawing ratio, thus causing the formation of determined breaks which supply the desired fiber ends.
