摘要：

Consumers are increasingly interested in the availability of papers obtained by non-pollutant methods (TCF bleaching, biotechnological techniques, ...) as well as in the substitution of fresh wood fibres for recycled or nonwood fibres. The objectives of the research were to study a TCF bleaching sequence for wheat straw soda pulp and to study the influence of enzymatic treatment on ozone bleaching kinetics. Paper (bulk, permeability, tensile, burst, tear and folding) and some effluent (COD and colour) properties were studied. Some conclusions were obtained: Improvement in brightness and kappa number was possible with xylanase pretreatment and good perspectives for TCF bleaching of straw pulp are expected.
