Abstract

In this study the effects of three non-ionic commercial SURFACTANTS namely PEG-1000, KELA-2 and KECA-20 as digester additives at four levels of 1, 2, 3 and 4% on the CMP PULPING of POPLAR, oxidative bleaching of the resulted pulp and its hand-sheet paper properties were investigated. The resulted pulps from the application of each surfactant with the highest screen yields and lowest rejects as well as control CMP pulps (without surfactant) were selected and bleached in two stages with H2O2. The pulping and bleaching results showed that the application of all SURFACTANTS increased accepted yield, consumption of bleaching agents and brightness of pulp whereas they lowered the opacity and yellowness of pulps compared to the control pulp. The best result was obtained with PEG-1000 (4%) which increased accepted yield by 1.2%, brightness by 2% while decreased screen reject by 1%. KELA-2 (2%) increased accepted yield, and brightness by 0.68% and 1.9%, respectively. KECA-20 (1%) increased accepted yield and brightness by 1.14% and 0.5% respectively but decreased screen reject by 0.87%. In addition, the prepared hand‐sheet papers had higher physical and mechanical properties compared with the control.
