Study on the mechanical and optical properties of kraft liner paper produced from mixing of OCC and virgin hardwoods kraft pulp

This study was aimed to investigate the effects of mixing OCC fibers with mixed hardwoods kraft pulp at Iran Wood and Paper Industry Co (Chuka). OCC has been repulped according to the common method in paper recycling industry and its freeness, along with that of virgin kraft pulp, were measured. The...
