PRODUCTION METHOD OF SOLUBILITY PULP MADE FROM DIOSCOREA BATATAS

摘要

PURPOSE: A method for fabricating pulp derived from Dioscorea batatas for dissolution is provided to enhance production yield and to minimize discharge of environmental pollutant by treating Dioscorea batatas with antibacterial and deodorizing functions with microorganisms and preparing pulp. CONSTITUTION: A method for fabricating pulp derived from Dioscorea batatas for dissolution comprises: a step of removing seeds and leaves from Dioscorea batatas; a step of transversely cutting Dioscorea batatas; a step of screening and washing(101); a step of peeling to obtain a stalk(102); a step of cutting the stalk and preparing hair chip(103); a step of injecting white rot fungi to the hair chip(104); a step of adding water or steam, and sulfur dioxide or sulfuric acid to the hair chip and dissolving hemicellulose(105); a step of putting the hair chip to a digester, and digesting in a liquid containing water, alkali, and anthraquinone at high temperature(106); a step of removing foreign materials(107); a step of adding the digester and digesting undigested parts and selecting(108); a step of washing selected parts to remove the liquid and concentrating(109); a step of bleaching the pulp(110); a step of treating the pulp with acid, and washing to remove metal ions(111); and a step of rolling the pulp(112).
