摘要: The invention relates to the use of certain lipolytic enzymes such as cutinases and lipases in the manufacture of paper and paper products from recycled paper. Examples of such enzymes are derived from strains of Humicola, Candida, Fusarium and Pseudomonas. By use of these enzymes, the problems relating to the so-called “stickies” derived from waste paper are reduced.

摘要: The invention relates to processes for treating a pulp, and for making a paper material such as paper, cardboard, linerboard, corrugated paperboard, tissue, towels, corrugated containers, boxes etc., these processes comprising an alkaline treatment of a pulp, a treatment with a pectin lyase and/or a pectate lyase, and, if desired, a draining of the pulp. Pectate lyase in combination with pectinesterase may be substituted for pectin lyase. The invention also relates to the use of xylanase, pectin lyase, pectate lyase, and/or the combination of pectate lyase with pectinesterase for anionic trash reduction and/or reduction of cationic demand of a paper pulp.

摘要: Methods for reducing energy required for a pulp refining processes by treating a mechanical pulp with a hemicellulase composition are presented. The enzymatic treatment can be carried out at a temperature of from about 10° C. to about 90° C., and/or at a pH of from about 2 to about 10. Paper made from the treated pulp has improved strength over paper made from untreated pulp.
