Characterisation of enzymatic retted pineapple leaf fibres / Norsyazana Mohamed Saad

This study focused on the development of enzymatic retting for the pineapple leaf fibre using combination of enzymes and chemicals. Formulations used in this project were cellulase and EDTA, pectinase and EDTA, xylanase and EDTA, and combination of the cellulase, pectinase, xylanase and EDTA. Untrea...
