the effect of adding cold soda pulp from cladophora green algae on fluting properties of nssc pulp

wood resources, non-wood plants and recycled papers are the common raw materials of papermaking. shortage of raw materials, is a challenging problem in developing pulp and paper industry. in this study, cladophora green algae was used as a new source of cellulosic fiberfor pulping and papermaking.. cladophora algae was cooked with cold soda method and then was mixed with nssc pulp at 10,20 and 30% loadings. structural and strength properties of the obtained pulp were studied and were compared with hardwoods nssc pulp. the results showed that strength properties of the neat cold soda pulp from the algae were inferior than the corresponding properties of hardwoods nssc pulp. moreover, by incorporation of the green algae pulp to nssc pulp, pulp strengths were reduced. so that, it is not a suitable source for production of fluting pulp.. according to the obtained results, cladophora green algae cold soda pulp could be mixed in low percentages (up to 10 %) with nssc pulp.
