Improvement of quality of printing papers obtained through implementation of a new microparticle retention and drainage program

摘要

The qualities of wood-free and mechanical base papers produced with two microparticle programs were compared. Improvement of the topographical characteristics of the base paper was observed when the microparticle was a colloidal borosilicate inorganic oxide. The results presented in this paper suggest that, in addition to machine parameters, the retention, drainage and formation-program can have a marked influence on the paper quality.
