Normal Pressure Pulping of Jute, Kenaf and Mesta Bast Fibers.

摘要: To develop a simple pulping technique for small scale papermaking, combination of ammonium oxalate pretreatment and alkaline hydrogen peroxide treatment at normal pressure was examined jute, kenaf mesta bast fibers. The seems sufficient to remove transition metal ions (Mn, Fe Cu) part Ca Mg give favorable profile the second pulping. brightnesses pulp samples were about 60_??_70% 5% H202 dosage although kappa numbers still high. strength properties pulps comparable with those commercial softwood bleached kraft except folding endurance. may have enough some practical use in local mills.
