Identification of Cellulosic Fiberfines Properties in Kraft, Chemical Mechanical, and Recycled Pulps

Cellulosic fines are essential parts of paper making system which impart remarkable effects on the production process parameters and the quality of final product. In this study, properties of fiberfines prepared from three kinds of pulps including Kraft, chemical mechanical (CMP), and recycled (OCC)...

Required amounts of fines were prepared using Valley Beater apparatus.
