PAPER COMPOSITION

摘要

The composition is used in the production of packing paper. The paper produced has improved mechanical strength indices and a higher degree of sizing and retention of the short fibres. The paper suspension is quickly dewatered and it is possible to work with a bigger quantity of short-fibres. The paper composition includes softwood and hardwood cellulose, wood pulp and recycled paper, rosin glue, aluminium sulphate and the polymers co-condensation amino-methylated product of saponified polyacrylonitrile and polyethylene oxide. The components are in quantities of percentage of absolute dry fibre material as follows: rosin glue from 0.25 to 3.0, polymers from 0.1 to 1.0 in proportion 5:1 to 9:1.
