STAPLE FIBRES OF SOLVENT-SPUN CELLULOSE ARE MAFDE BY A METHOD IN WHICH :(i) CELLULOSE IS DISSOLVED IN AN AMINE OXIDE SOLVENT TO FORM A HOT CELLULOSE SOLUTION, (ii) THE HOT CELLILOSE SOLUTION IS EXTRUDED THKROUGH A DIE ASSEMBLY TO FORM A TOW OF CONTINUOUS FILAMENTS, (iii) THE TOW IS PASSED THROUGH A WATER BATH TO LEACH OUT THE AMINE OXIDE,(iV) THE TOW IS CRIMPED BY PASSING THROUGH A STUFFER BOX IN WHICH IT IS COMPRESSED TO APPLY CRIMP, (V) DRY STEAM BEING INJECTED INTO THE STUFFER BOX DURING THE CRIMPING PROCESS, AND (Vi) THE CRIMPED TOW IS PASSED TO A CUTTER AND CUT TO THE DESIRED FIBRE LENGTH.AN APPARATUS IS ALSO PROVIDED IN WHICH THE STAPLE FIBRES CAN BE MADE.
