Fiber morphological characteristics of kenaf core as affected by refining parameters


Amerudin, Nazihah (2016) Fiber morphological characteristics of kenaf core as affected by refining parameters. [Project Paper Report]


The main objective of this study was to determine the effect of refining time on the morphology of refined kenaf and rubberwood fibres at different kenaf-rubberwood ratio. Five kenaf-rubberwood ratios (100K, 100R, 20K: 80R, 30K: 70R, and 50K: 50R) and two refining time (10 and 15 minutes) were used in the refiner at 6 bar pressure. After refined, the fiber obtained were sampled out to evaluate the yield, fibre distribution and fiber morphology. For fibre distribution study, four screening size were used; 0.125, 0.2, 1.0, 2.0, <0.125, and 0.4 mm. In this study, the characteristics observed and measured were length, width, cell wall, and the width of the lumen of kenaf core fiber and rubberwood. Findings shows that 30K: 70R at 10 minutes has the highest yield at 63.33%. All ratio generated fibres with similar distribution as commercial fibre. Furthermore, rubberwood and kenaf core disingly different fibre morphology. The fibre length of rubberwood is 834m and kenaf core is 689m based on 0.4mm and <0.125mm screening size.
