Kraft pulping properties of individual species from Sarawak forest resources

The kraft pulping properties of 72 major species most of which were dipterocarps from the Sarawak mixed dipterocarp forests had been investigated. The properties varied widely between species and generally the yields of pulp from most species were satisfactory although a rather high alkali charge was required for pulping. Pulp tearing strengths were high but breaking lengths were less satisfactory although adequate for a range of end products which do not require high strength. A number of species produced pitch deposits during papermaking operations. Compared with peat swamp species the mixed dipterocarp forest exhibited poorer pulping properties but similar papermaking properties

Abstract

The kraft pulping properties of 72 major species most of which were dipterocarps from the Sarawak mixed dipterocarp forests had been investigated. The properties varied widely between species and generally the yields of pulp from most species were satisfactory although a rather high alkali charge was required for pulping. Pulp tearing strengths were high but breaking lengths were less satisfactory although adequate for a range of end products which do not require high strength. A number of species produced pitch deposits during papermaking operations. Compared with peat swamp species the mixed dipterocarp forest exhibited poorer pulping properties but similar papermaking properties
