Document Type and Number:
WIPO Patent Application WO/2015/016431
Kind Code:
A1
Abstract:
The present invention relates to a fiberization method of knots for the reuse of undigested knots during the digestion of wood chips for manufacturing pulp outside a pulp production process, fiberized knots using same and paper products using the fiberized knots. By fiberizing and using knots, which have commonly been classified as waste and involve excessive cost to discard, in the production of paper products, the cost for discarding knots in a pulp process may be reduced, and the danger of degrading the final quality of pulp (when knots are recycled into pulp using a method of the prior art) may be reduced.
