Physicochemical Characterization of Microcrystalline Cellulose Extracted from Kenaf Bast

Investigation of the physicochemical properties of microcrystalline cellulose from agricultural wastes I: orange mesocarp

Orange mesocarp was obtained after removal of the epicarp and the endocarp from oranges. It was dried, pulverized and digested with 2% w/v sodium hydroxide at 80 C for 3 h. Alphaand micro-crystalline celluloses were extracted from the pulp using 17.5% w/v and 2.5 N hydrochloric acid, respectively. The physicochemical and powder properties of the extracted material were evaluated. Results obtain...

Characterization of Epoxy Composites Reinforced with Wax Encapsulated Microcrystalline Cellulose

The effect of paraffin wax encapsulated microcrystalline cellulose (EMC) particles on the mechanical and physical properties of EMC/epoxy composites were investigated. It was demonstrated that the compatibility between cellulose and epoxy resin could be maintained due to partial encapsulation resulting in an improvement in epoxy composite mechanical properties. This work was unique because it w...

Comparative Properties of Soda Pulps from Stalk, Bast, and Core of Malaysian Grown Kenaf

Soda pulping was performed using kenaf stalk, core, and bast as raw materials. It was observed that all these components could yield good paper characteristics when the resulting pulps were beaten to a freeness of 200 to 300 mL. Soda pulp made from the stalk was comparable to the frond from oil palm in sheet properties, but the latter would require higher beating energy to reach similar freenes...

A Chemical Process for Preparing Cellulosic Fibers Hierarchically from Kenaf Bast Fibers

The objective of this research was to evaluate an all-chemical process to prepare nano-scale to macro-scale cellulosic fibers from kenaf bast fibers, for polymer composite reinforcement. The procedure used in this all-chemical process included alkaline retting to obtain single cellulosic retted fiber, bleaching treatment to obtain delignified bleached fiber, and acidic hydrolysis to obtain both...
