摘　　要：为制备具有高湿强度和高透气度的衬垫纸,引入自制的亲水聚酯短切纤维与植物纤维混抄,探讨纸浆打浆度、纤维配比、抄造用水电导率、pH调节剂等助剂对纸张性能的影响,确定试验条件下的最佳参数,测定了衬垫纸的物理性能、抗菌和防霉性能。结果表明:在试验条件下,阔叶木浆与亲水性聚酯短纤维的质量比为8∶2,水体电导率为21μS/cm,硼酸、湿强剂和抗菌剂相对于绝干浆的质量分数分别为1.5%、0.6%和0.3%,制得的衬垫纸湿强度为0.72 kN·m^(-1),透气度为30.99μm·(Pa·s)^(-1),对金黄色葡萄球菌和大肠杆菌抑菌率分别达到了100%和95.84%,同时在高温、高相对湿度条件下,防霉性能良好。亲水性聚酯纤维的添加可以显著改善衬垫纸的性能,为衬垫纸的制备提供新思路。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 21μS/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 30.99μm·(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.
