Abstract

THE INVENTION CONVERNS A PROCSS FOR THE PRODUCTION OF CELLULOSE FIBRES BY EXTRUDING A SOLUTION OF CELLULOSE IN A TERTIARY AMINE-OXIDE THROUGH SPINNING HOLES OF A SPINNERET AND CONDUCTING THE EXTRUDED FILAMENTS ACROSS AN AIR GAP INTO A PRECIPITATION BATH WHILE DRAWING THEM, CHARACTERIZED IN THAT THE PROCESS IS CARRIED OUT IN A WAY THAT THE MATHEMATICAL EXPRESSION51,4+0,033XD+1937XM2-7,18XT-0,094XL-2,50XF+0,045XF2,WHEREIN D IS THE SPINNING HOLE DIAMETER IN µM, M IS THE DOPE OUTPUT PER HOLE IN G/MIN, T IS THE TITER OF THE INDIVIDUAL FILAMENT IN DTEX, L IS THE LENGTH OF THE AIR GAP IN MM AND F IS THE HUMIDITY OF THE AIR IN THE AIR GAP IN G OF WATER/KG OF AIR, DOES NOT EXCEED THE NUMBER 10, WITH THE PROVISION THAT THE LENGTH OF THE AIR GAP IS PROVIDED GREATER THAN 30MM. THAT PROCESS LEADS TO CELLULOSE FIBRES HAVING A VERY WEAK TENDENCY TO FIBRILLATION.
