Wollastonite fiber can be specially applied in paper making as filler, which is a new raw material of paper making. It can partly replace wood pulp, straw pulp and waste paper pulp and other paper making raw materials in the packing paper and cultural paper. It can effectively improve physical properties of paper’s whiteness, opacity, deflection, evenness, the cover rate and surface properties. At the same time, Wollastonite fiber retention rate is up to 80%. Wollastonite’s fluidity and dispersion not only meet the requirements of paper-making process but also greatly enhance the material utilization rate, reduce the cost of paper products, reduce the emission of pollutants.
