Abstract:
The invention relates to a method and system for manufacturing a fibrous yarn. An aqueous suspension having fibers and at least one rheology modifier is directed through at least one nozzle to form at least one fibrous yarn. The said nozzle is adapted to swirl the flow of the aqueous suspension around the main flow axis of the said nozzle. Then the aqueous suspension at the exit of the nozzle is merged with at least one annular flow comprising at least one cross linking reagent. Then the fibrous yarn is subjected to pressing mechanism. The pressing mechanism is adapted to dewater and twist the fibrous yarn. Finally, a fibrous yarn product having improved physical properties is produced.
