Document Type and Number:

WIPO Patent Application WO/2018/159980

Kind Code:

A1

Abstract:

Disclosed is a method for manufacturing pulp by using a red algae or red algae residue pulped with an aqueous alkaline solution. The present invention comprises the steps of: (1) washing a red algae or a red algae residue left after extraction of an agar ingredient; (2) pulping the washed red algae or red algae residue by immersion in an aqueous alkaline solution; (3) making fibers through mechanical treatment in water of 40-100°C after the pulping step; (4) bleaching the fibrous residue; and (6) sorting out the bleached residue by use of a cleaner and a screen.
