Reducing the Water and Water Vapour Absorbence and Enhancing the Dimensional Stability of Paper and Paper Products and Use of Coated Paper Products

摘要

The invention relates to a method for reducing the absorption of water and water vapor and for increasing the dimensional stability of paper and paper products by treatment with an aqueous solution and/or dispersion of at least one reactive material which reacts with itself and/or cellulose fibers with crosslinking, cellulose fibers or a paper product obtained therefrom by drainage on a wire being compressed, the compressed paper product then being brought into contact with an aqueous solution and/or dispersion of the reactive material, the compression being eliminated with further action of the aqueous solution and/or dispersion and the paper product being dried and crosslinked, and to the use of the coated paper products thus obtainable and/or of the coated cellulose fibers which can be produced therefrom by defibrating as an additive to thermoplastics and as an additive to heat-curable plastics.
