资源简介:
The invention relates to pulp and paper industry and can be used in the manufacture of paper sanitary or filtering purpose. A method of producing absorbent paper, which involves grinding of sulfate bleached pulp from coniferous and deciduous of wood, with the production of fibrous slurry, the formation of paper cloths, its fastening and drying, which is different the fact that the fibers of the sulfate bleached pulp of coniferous wood is ground to the degree of grinding 29-36 ° C (I fraction); as sulfate bleached cellulose with deciduous wood use a mixture of bleached sulfate pulp fibers eucalyptus wood and sulphate bleached pulp fibers from aspen wood the ratio, wt. % 55 and 45 respectively, which are ground together to the degree of grinding 17-23 ° WR (fraction II); and before by forming a paper web, the obtained fiber fractions are mixed with each other water by weight ratio%: pulp fibers of sulphate bleached from coniferous wood 52-58; a mixture of bleached pulp fibers of eucalyptus wood and sulfate bleached pulp from aspen wood 42-48.
