<p>Methods for the modification of pulp fibers, such as recycled and/or virgin fibers, to increase the pulp drainage and/or strength and/or increase the rate of water absorption of resulting handsheets and/or paper products are described herein. The methods involve treating pulp with expansin and/or swollenin in combination with an enzyme composition containing one or more hemicellulases, one or more pectinases, and combinations thereof. In one embodiment, the enzyme composition further contains one or more cellulases, for example, one or more endo-glucanases. The expansin and/or swollenin can be applied simultaneously with the enzyme composition in the same formulation or different formulations.</p> |
