| Popis: | Properties of cellulose extracted from Valoniopsis pachynema, which is a commercially unexploited green seaweed found in Indian waters was evaluated for its microcrystalline properties and paper forming abilities. The crude cellulose obtained from the seaweed was found to have a high crystallinity (95%) equivalent to commercially available microcrystalline cellulose samples (e.g., HiCel™ with 91% crystallinity). When the seaweed cellulose pulp was processed to prepare paper, it was observed that the chemical and strength properties (particularly high tear) of the paper sheet are similar to the paper sheets prepared from non-wood pulps such as soft wood and bamboo, and the qualities were inferior to the ones prepared from wood pulps. Hence, this seaweed pulp can be utilized for making paper by partially blending with other pulps. Due to the presence of good quality cellulose, this seaweed can be exploited as a new source of cellulose having practical applications. |
