Ground kenaf core as a filtration aid
Industrial Crops and Products, 2001Abstract The objective of this study was to examine the filtration characteristics of ground kenaf core, a waste material generated during the production of kenaf bast fibers for paper. The constant-pressure precoat filtration characteristics of ground kenaf core were compared to commercial diatomaceous earth (DE).

An irradiation-alkaline pretreatment of kenaf core for improving the sugar yield
Renewable Energy, 2015Kenaf (Hibiscus cannabinus) has received considerable attention as a renewable resource because of its fast growth and low lignin content. In the present study, a combination pretreatment of kenaf core using electron beam irradiation (EBI) and dilute alkali was investigated to improve the sugar yield in enzymatic hydrolysis.

Finely milled kenaf core as a natural plywood binder
Holzforschung, 2007Abstract Application of kenaf core powder as a natural plywood binder has been studied. In the first instance, binderless boards made of kenaf core powder and overlaid sugi (Cryptomeria japonica D. Don) veneers resulted in immediate veneer delamination.

Water absorption characteristics of kenaf core to use as animal bedding material
Industrial Crops and Products, 2009Kenaf is grown these days as a minor fibre crop in some Asian countries, but also in the US and recently in Southern European countries such as Italy. The yield of extracted bast fibres is below 1/3 of that of the kenaf stem weight. In the US and Europe a profitable outlet for the remaining woody core is important for economical production of the crop.

Thermal Analysis of Kenaf Sandwich Core Panel
Advanced Materials Research, 2012The thermal stability of kenaf sandwich panel core structures are presented in this paper. Sandwich core structures tested are of varying kenaf percentage being 10, 20 and 30 wt%. The result indicated that all composite have two step degradation processes due to the presence of kenaf in epoxy.

Rigid polyurethane and kenaf core composite foams
Polymer Engineering & Science, 2014Rigid PU foams are valuable in many construction applications. Kenaf is a bast fiber plant where the surface stem skin provides bast fibers whose strength‐to‐weight ratio competes with glass fiber. The higher volume product of the kenaf core is an under‐investigated area in composite applications. The naturally porous structure of kenaf‐core provides a

Chemical and instrumental characterization of maturing kenaf core and bast
Industrial Crops and Products, 1999Abstract A limiting factor in the production of bast fiber from kenaf is retting, the process by which the fiber is freed from the non-fibrous tissue. An objective of this study was to evaluate the variation in cell wall chemistry with maturity for different cultivars, particularly in relation to lignin and retting.

Self-bonding characteristics of binderless kenaf core composites
Wood Science and Technology, 2005We investigated optimum self-bonding conditions of kenaf core composites manufactured by steam treatment, and discussed on the roles of cinnamic acids in the self-bonding mechanism. The presence of cinnamic acids in the kenaf core and its composites were analyzed by pyrolysis gas chromatography-mass spectrophotometry in the presence of tetramethyl ...
