| Abstract:In this paper, the manufacturing process of efficient vacuum dust collecting bag base paper by using the cylinder paper machine was investigated. Some important parameters were determined, including the fiber type （natural wood fiber and synthetic fiber） and proportion, the mechanical treatment for the fiber materials, the chemical additives, surface sizing process and cylinder paper machine operation conditions. Finally, the optimized conditions for producing this specialty paper were obtained. The results showed that when the ratio of softwood pulp and synthetic fiber was 75∶25, the adding dosage of PAE was 0.6%, the ratio of OS and CMC was 1∶1, and the concentration of sizing agent was 4%, the air permeability and strength properties of dust collecting bag base paper were the best. |
