Influence of Cationic Alkoxylated Amine Surfactant on Optical and Mechanical Properties of Paper
Recently,there is a steadily increasing demand for the application of surfactants as debonding agents in tissue manufacturing.Since cellulose fibers possess negative charges,cationic surfactants could be readily adsorbed on fibers,thus facilitating their utilization in paper industries.The work presented herein focused on the application of cationic alkoxylated amine surfactant into the stock of unrefined and refined sulfite pulps.The results showed that as the dosage of the surfactant was increased up to 10 mg/g on unrefined pulps,the reductions on tensile and burst indices of treated papers was up to 10％ and 14％,respectively.These reductions corresponded to 11％ decline in the fiber bonding index calculated from Pages Equation.However,the tear index was increased by 20％.Furthermore,the application of surfactant(10 mg/g)on the refined pulps led to the increment in light scattering coefficients,regardless of the refining loads.Additionally,the influence of surfactant on the tear index was impaired with increasing the refining loads.
