a) at least one lyocell dope vessel for storing cellulose dope;

b) at least one metering pump for pumping said cellulose dope into at least one spin pack containing at least one spinneret that extrudes the cellulose dope as spun filament yarn;

c) a regeneration bath containing a solution for partial regeneration of the extruded spun filament yarn;

d) at least one winder for stretching extruded spun filament yarn while it passes through an air-gap of controlled conditions and the regeneration bath solution to create a stretched yarn;

e) an individual yarn guiding drum;

f) a main drum having a filament yarn washing section and a filament yarn drying section,

wherein the individual yarn guiding drum guides the stretched yarn from the at least one winder to the main drum spinning at a speed less than the winder speed, wherein the main drum speed to winder speed is selected from a ratio of 1.00 to 0.85, wherein the filament yarn washing section comprises sequential washing zones, each successive washing zone containing a washing solution of successively decreasing concentration of N-methyl morpholine N-oxide (NMMO), said concentration successively decreasing to up to 0% by weight of NMMO, and

wherein the filament yarn drying section has a temperature of 40° C. to 100° C. for drying the washed filament yarn to create a dried lyocell filament yarn having a tenacity greater than 3.2 grams per denier and elongation greater than 8%; and

g) a circulating pump to maintain uniform concentration of the NMMO in each washing zone.
