Abstract

Penetrating agents have been examined to find means to improve oil and water resistance and water repellency of commercial size using the perfluoroalkyl acrylate copolymer. The 10EO-4PO adduct with C8-10 alcohol as penetrating agent in the size pressing procedure has been shown to maximize these three parameters of this copolymer and improve them in the case of commercial size paper. With application of a mixture containing 0.75-1.00 wt% EO-PO adduct and 1.50-3.00 wt% perfluoroalkyl acrylate copolymer to commercial size paper at a fixation ratio exceeding 43 wt%, pulp fiber surface of the paper was noted to be completely covered with perfluoroalkyl acrylate copolymer. Application of a EO-PO adduct and perfluoroalkyl acrylate copolymer mixture to commercial size paper is thus very effective for improvement of these parameters.<br>
