NOVELTY – Cellulose pulp comprises 96% of water and 0.05-5% of protonated chitosan on a dry basis. USE – Cellulose pulp used in paper (claimed). ADVANTAGE – The cellulose pulp provides paper without using buffering agent, where the formed paper ensures high absorption or retention for water and oil. DESCRIPTION OF DRAWING(S) – The drawing shows a graphical representation depicting results of total water absorption comparative between conventional paper samples and particulate chitosan paper.
