The method disclosed relates to the production of paper yarn from cellulose-containing plant species, in the textile sector, and particularly relates to obtaining a paper yarn by a wet spinning method using high or low purity cellulose raw material isolated from the wild plant species of Calluna Vulgaris.

A Japanese paper yarn manufacturing device according to the present invention that provides a method for mass-production of inexpensive Japanese paper yarns by saving labor includes a slitter that slits a Japanese paper sheet fed out from a Japanese paper roll into a plurality of Japanese paper tapes each having a narrow width in a feeding direction, and a distributing section that distributes the plurality of slit Japanese paper tapes. An air flow section feeds air into a plurality of the tubes of the distributing section, so that the distributed Japanese paper tapes are sent in a floating manner to a plurality of yarn processing device units.

The present invention discloses a method for the manufacture of fibrous yarn. The said method includes the steps of providing an aqueous suspension having fibers and at least one rheology modifier, followed by directing said suspension through at least one nozzle, to form at least one yarn. The method further includes subjecting the said at least one yarn to dewatering. The method is characterized in that a hydrogel is provided onto surface of the yarn that exits the at least one nozzle. Further disclosed is a system for manufacture of fibrous yarn and the fibrous yarn so produced during the manufacturing.

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.
