Abstract In order to prepare liner paper with high wet strength and high air permeability, the self-made hydrophilic polyester chopped fibers and plant fibers were introduced into the paper,the influence of pulp beating degree, fiber ratio, conductivity of papermaking water, pH adjuster and other additives on paper properties was discussed,the optimal parameters under the test conditions were determined, and the physical properties, antibacterial and mildew proof properties of liner paper were determined. The results showed that under the test conditions, the mass ratio of hardwood pulp to hydrophilic polyester staple fiber was 8∶2, and water conductivity was 21 μS/cm;the mass fractions of boric acid, wet strength agent and antibacterial agent relative to absolute dry pulp were 1.5%, 0.6% and 0.3%,respectively, and the obtained liner paper had a wet strength of 0.72 kN·m-1, an air permeability of 30.99 μm·(Pa·s)-1, and is resistant to Staphylococcus aureus and Escherichia Coli. The bacteriostatic rates of bacilli reached 100% and 95.84% respectively, as the antifungal performance was good under the conditions of high temperature and high relative humidity. The addition of hydrophilic polyester fibers can significantly improve the performance of liner paper, and provide new ideas for the preparation of liner paper.
