| Abstract:Well dispersion of aramid fibers is very important to the properties of aramid paper. In this work, the effect of aramid fibrils/chopped fiber ratio on foam properties and paper properties in foam forming system was investigated. Results showed that foam forming could increase 3 percentage points dryness of paper after pressing. Forming consistency of aramid paper by foam-forming could be eight times higher than that of conventional forming when similar formation index was obtained. In addition, tensile index of foam-forming paper increased about 35.4% compared to conventional forming paper at forming consistency of 0.4%. Meanwhile, dielectric strength was not affected negatively. In conclusion, foam forming had great potential in energy saving and dispersion of long fibers. |
