Treatment of alkaline treated pulp for use in papermaking.

摘要

The present invention relates to a method of making paper from bleached or alkaline treated pulp by dewatering pulp containing bleached or alkaline treated vegetable fibers from wood or non-wood species. It was found that such bleached or alkaline treated pulps contain a substantial amount of harmful pectins. By incorporating pectinase in the bleached or alkaline treated pulp such harmful pectins in the aqueous phase of the pulp are degraded and thus rendered harmless to papermaking processes.
