The invention discloses a method for improving the reactive performance of prehydrolysis
sulfate dissolving pulp. The prehydrolysis
sulfate dissolving pulp of needle leaf wood or broad leaf wood with the concentration of 30 percent is adopted, 18 L of water are firstly added to a pulp tank of a pulping
machine, the pulp is added slowly, water is supplemented, so that the concentration of the pulp reaches 1.57 percent, pulping is carried out for 10-90 minutes, the pulp is concentrated to the concentration of 20 percent, then the pulp is taken and transferred into a
polyethylene plastic bag with a sealing opening,
distilled water and
cellulase liquid are added to dilute the pulp to the concentration of four percent,
enzyme / bone dry pulp is 3.0 u / g-4.0 u / g, the pH value is adjusted to be three to six, and the pulp is placed in a water bath kettle to be treated. Suction
filtration is carried out on the treated pulp, water of 90 DEG C is added to the pulp until the concentration of the pulp is four percent, heating is carried out for 30 minutes, and the pulp is air-dried to the concentration of 95 percent under the condition of constant temperature and constant
humidity. The method has the advantages that the reactive performance of the
dissolving pulp is improved by combining mechanical treatment and
enzyme treatment, and the reactive performance of the prehydrolysis
sulfate dissolving pulp can be improved.
