Abstract: The migration behavior of starch sizing solution under different drying conditions in glass fiber cake was studied. Results indicated that the organic matters diffused with the evaporation of water, and the organic content distributed in glass fibre cake presented “W” type, which was influenced by the evaporation of water and the chromatography effect of glass fiber. Simulation experiment proved that the distribution of organic matters in the fibre cake was affected by the evaporation direction of water. The distribution behavior of organic matters on glass fibre can be inducted by changing the local evaporation velocity difference of fibre cake, which can be adjusted by changing the evaporation direction of water and blowing direction during drying process.

Key words: glass fiber, migration, drying condition, evaporation of water, organic material content
