Abstract

The pulping and papermaking characteristics of a tropical softwood (Pinus caribaea var. hondurensis) and a tropical hardwood (Gmelina arborea) were investigated. Trees were harvested from a plantation in Ghana, and chips were delignified by the kraft process. Handsheets (75 g/m(2)) were produced from various blends of bleached softwood and hardwood pulps. The results show that hardwood pulp can be substituted up to 50% without compromising sheet mechanical properties. Addition of mineral filler and rosin size to the furnish reduced sheet mechanical properties, especially fold endurance and tear index.
