Abstract
Laboratory studies on processes combining enzyme with new bleaching te chnologies are described. The application of xylanase subsequent stage s. Methods combining xylanase treatment (X), bleached in the XAZZP(1.2 %) sequence exhibit a brightness of 90 Photovolt compared with 85.2 Ph otovolt for the AZZP(1.7%). The physical properties of the bleached pu lps are comparable to those produce pulps exhibiting a high degree of brightness without chlorination.
