The applicability of arrowroots as materials for paper manufacture was investigated by evaluating the characteristics of arrowroots pulping and pulps, and the surface characteristics of paper made of arrowroots. The results is as follows.
The yield of grounded pulp, alkaline pulp, grounded bleach pulp, and alkaline bleach pulp are 98.0%, 37.7%, 84.8%, and 32.5%, respectively.
The extraction components in arrowroot’s fibers was shown high in 1%-NaOH extraction. The amount of holocellulose and lignin were largely decreased, but a slight decrease was shown in the bleaching processes.
Many shivers were shown in the grounded fibers. The amount of shivers was decreased and the single fibers were increased during the process of bleaching.
The alkaline pulp and the alkaline bleach pulp showed high in the beating time and freeness than the grounded pulp and grounded bleach pulp.
The conditions of sheet surface according to beating time is effected largely by the conditions of original pulp.
