METHOD FOR OBTAINING PLANT OUTER BARK FIBER AND PLANT STEM CORE FROM PLANT STEM, SYSTEM FOR PROCESSING PLANT STEM AND KENAF OUTER BARK FIBER MASS OBTAINED BY THE METHOD

摘要

It is intended to provide a method and a system for separating an industrially applicable plant outer bark fiber and plant stem core of kenaf or the like into a plant outer bark fiber and plant stem core at a high speed without using heat or chemicals and only with water and physical action by mechanical processing. The plant outer bark fiber and the plant stem core are obtained from the plant stem by putting the plant stem into a plant stem-grinding device equipped with a grinding roller thereby to peel the plant outer bark from the plant stem, separating the plant outer bark and the plant stem core using a difference in the specific gravities of the plant outer bark and the plant stem core, sending only the plant outer bark to a plant outer bark rolling device, rolling the plant outer bark with a pressure roller to form a sheet-like shape and sending it to a plant outer bark fiber fibrillating and washing device, and washing out plant components other than the plant outer bark fiber by high-pressure water jetting thereby to obtain only the plant outer bark fiber.
