Application of Composite Addictives in Paper-Making Using Slag-wool Fiber

Ying Han, Wen-Jiang Feng, Wei Cheng, Feng Chen, Rong-Rong Chen


The composite paper was made successfully from the heterogeneous mixture of common pulp and slag-wool fibers,
without/with different amounts of composite addictives. These physical properties, including tensile strength,
folding endurance, and smoothness, etc., were investigated in detail. All physical properties of the composite paper,
made from the 30% slag wool fibers & 70% paper pulp, and no any composite addictive, decrease sharply, in
comparison with common paper. While for the same paper with addition of optimum amount (0.5%) of composite
addictives, the tensile strength increases by 15%, while the folding endurance, by 40%. Therefore, it is vital to
introduce composite addictives in the process of composite papermaking. The aforementioned investigation can
reduce the amount of paper pulp, and therefore, protect our forest resource.
