Effect of Xylanase Pretreatment of Wood Chips on Fiber Separation in CTMP Refining Process

摘要：

The effect of xylanase treatment of eucalyptus wood chip on chip refining and fiber property was investigated.The fiber separation region and fiber surface structure were observed with SEM and TEM.The fiber length and fines were analyzed with Bauer-McNett and FQA.The results show that xylanase degraded and hydrolyzed some xylan in the fiber wall,thus loosing the fiber wall structure.Therefore,in the subsequent refining process,fiber separation occurred in the secondary wall.This results in fibers with less lignin and extractives on the surface,which will benefit the interfiber bonding.
