JOURNAL FREE ACCESSThis is to illustrate our experience of developing mangrove for the use of coated paper and woodfree printing paper. Mangrove species harvested in South-east Asia are generally lager in wood density and have very thick fibrous membranes which deteriorate papermaking suitability, although they cause no problem in cooking and bleaching with sulphate pulping process. When paper is made from hardwood pulp only, which is the case with KANZAKI, papermaking suitability of mangrove pulp has to be more improved. We achieved this purpose through beating by the use of refier of stone bar.View full abstractDownload PDF (2363K) -

JOURNAL FREE ACCESSKraft-pulping tests were made on some samples of three soft-wood and two hard-wood species in Guatemala which were obtained in connection with the survey tour there by our staff members 1969.
Generally speaking, they were cooked as easily as the corresponding species in Japan. The resultant unbleached kraft-pulps from the soft-woods showed somewhat higher burst factor and percentage stretch but a little lower tear resistance and ring-crush factor than those from Japanese pine. The strength properties for the hard-wood pulps were roughly equal or slightly inferior to those for the typical Japanese hard-woods.View full abstractDownload PDF (1060K) -
