The chemical treatment step comprises a defatting step, a delignification step, and an alkali treatment step. At the alkali treatment step, an alkali treating liquid having 0.1-1.5 mass% concentration is used and it is preferable that the temperature is 10-40°C and the treatment time is within one hour. <P>COPYRIGHT: (C)2013,JPO&INPIT |
