Abstract

Viscosity of cellulose pulp was greatly decreased with endo-xylanase treatment but tiny decreased with exo-xylanase treatment. Change of freeness was greatly influenced with exo-xylanase treatment. The first stage of refining(5,000 revolution), freeness was greatly decreased with exo-xylanase treatment. After middle stage of refining(10,000 revolution) change of freeness was similar to endo-xylanase treatment. WRV(water retention value) was more effective exo-xylanas than endo-xylanase treatment. Interfiber bonding of cellulose fiber was disintegrated with exo-xylanse treatment.
