Abstract
Kenaf (Hibiscus cannabinus L.) is an annual plant which produces a very hig h fiber yield per hectare and has demonstrated to be a suitable material fo r pulping. The crop conditions influence fiber production, but there is no information about their effect on pulp quality. The aim of this work was to study the effect of kenaf varieties and crop conditions (watering dose and harvesting time) on sulfate pulp quality. The study has been made on bast fiber sulfate pulps due to their high added value. The quality criteria wer e fiber dimensions, chemical composition and pulp quality. Kenaf variety or crop conditions have significant effect on fiber dimensions, holocellulose content, kappa number and breaking strength. To obtain high fiber yield an d good delignified pulps it is recommended to grow the Salvador variety and to employ advance harvesting.
