Optimization Process Variables of Deinked Pulp Bleaching - Improvement of Wet Tensile Strength of Tissue Paper

In this study dispersed deinked pulp (DIP) of Latif Company which includes a mixture of straw printers, mixed office waste (MOW) and mechanical recycle paper was used to investigate the effect of bleaching variables on pulp and paper properties. Six variables of bleaching process including the amoun...
