Abstract:
      Using bleached softwood pulp as the fiber raw material and surfactants as foaming agents， a foam-molded paper with basis weight of (100±2) g/m2 was prepared by foam forming technology and flat drying method. The foaming properties of three surfactants like sodium dodecyl sulfate (SDS)， cetyltrimethylammonium bromide (CTAB)， and fatty alcohol polyoxyethylene ether (AEO-9) were investigated， as well as their effects on paper properties. The results showed that the three surfactants exhibited different foaming characteristics， with optimal foaming concentrations of 1.0 g/L for AEO-9， 0.5 g/L for CTAB， and 1.5 g/L for SDS. At pulp beating degree of 20 °SR， the paper prepared by foam forming with AEO-9 showed that the evenness index increased from 51.9 to 85.2， and the bulk increased from 3.95 to 5.43， with increase of 64.2% and 37.5%， respectively， compared to traditional formed paper.
