INVESTIGATION OF PROPERTIES OF ETHANOL-ALKALI, KRAFT AND SODA PULPS PREPARED FROM WHEAT STRAW

Global concerns for preservation of forests and elimination of pollution from pulping and papermaking processes has led us to explore alternate fibrous resources other than wood and new environmentally begin pulping and bleaching processes for papermaking without sacrificing quality. Various alterna...
