摘要

The surface lignin and extractives coverage of some nonwood pulps (wheat straw, reed, bagasse, bamboo and kenaf bark) were investigated by means of ESCA and compared with wood pulps. Strong enrichment of lignin and extractives on the pulp fiber surface was found for all of the pulps. At the same bulk lignin content level, the surface lignin coverage was found to be higher in the nonwood pulp than in the softwood pulp. The possible reasons for this were examined.
