    摘要： The removal of inks from a pulp fiber slurry is accomplished by use of a combination of (1) a polyester obtained through reaction between di and/or tricarboxylic acids and/or anhydrides thereof and a polyalkylene glycol or one or more alkylene oxides, (2) a first deinking agent which is an alkoxylated hydrophobic base, e.g. an alcohol, amine, acid, dimer acid, salts thereof, or the like, and (3) a second deinking agent which is a second alkoxylated hydrophobic base having a cloud point about 2 to 20° lower than the cloud point of the first deinking agent. Use of the three component combination allows an improved foam profile allowing longer continuous operation or one or more of a reduction in total chemical demand, optical bleach demand, and stickies.

    摘要： In the production of pulp and paper from starch-containing paper, the deinking effect can be improved by including treatment with both a starch-degrading enzyme and a pectate lyase. The process comprises enzyme treatment during or after disintegration of the paper to produce pulp, followed by separation of ink particles.
