Abstract (en)
A method for producing non-paper pulp natural fibers into paper pulp molded products, which is primarily produced by the following steps in sequence: a. scouring, b. bleaching, c. washing, d. dehydrating, e. pulverize, f. pulping, g. moldable pulp, h. paper pulp molding, and i. releasing, so as to obtain the paper pulp molded finished products made with non-paper pulp natural fibers. Accordingly, the present invention may use the traditional industrial waste such as palms, hemp and coconut shells as the major material for paper molded products to both decrease the cost of paper molded products and maintain the ecological environment of the earth.
