If kenaf lines differ in woody core fiber length and cellulose content, it may be possible to increase the pulp quality of kenaf through breeding. Forty-eight cultiYars, breeding lines, and accessions of cultivated kenaf (HibisCIlS camzabinus L.) were analyzed for diHerences in woody core fiber length and monethanolamine (MEA) cellulose, yield, and plant size. All commercial culth-ars of kenaf ...

In this study, various treated, untreated, and treated kenaf/glass fiber composites were fabricated using epoxy resin. A portion of kenaf fibers subjected to treatment with alkali, sub-portion was taken for benzoyl peroxide potassium permanganate prior composite fabrication. This on the material undertaken achieve improved modification interface between matrix bond. glass used enhancing mechani...

Fiber matrix adhesion was promoted by hybrid fiber composite surface modifications using an alkaline treatment. However, it was found that the resulting strength and stiffness of the composite. The elastic modulus of the composite did not improve with the fiber surface modification. A notable disadvantage of natural fibers is their polarity which makes it incompatible with hydrophobic matrix. T...

A series of non-wood plant fibers, namely kenaf, jute, sisal and abaca, have been analyzed upon pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) of the whole material. The pyrolysis products mainly arise from the carbohydrate and lignin moieties of the fibers. The lignin-derived phenols belonged to the p-hydroxyphenylpropanoid (H), guaiacylpropanoid (G) and syringylpropanoid (S) struct...

this study was devoted to the development of pulp luffa cclindrica and its characterization paper (annual plant fiber of the family cucurbitaceae). baking at soda helps to achieve a high level of delignification (kappa ≤ 10) and high yield (≈ 67%).the beatability stack valley is comparable to refined wood fibers, the fibers develop a normally time with good hydrophilic properties without excess...

nanofibrillated cellulose fibers were produced from unbleached kraft pulp of kenaf bast fiber. air dried and vacuum filtrated films of cellulose nanofibers were produced and their density and tensile properties were investigated. kenaf bast fiber unbleached kraft pulp has good potential for production of cellulose nanofibers by microfluidizer; so that the use of kenaf bast fiber unbleached kraf...

Bast fibers from stems of kenaf (Hibiscus cannabinus, L.), a warm-season tropical herbaceous annual plant, were dispersed into poly-L-lactide (PLLA) matrix by melt-mixing followed by compression molding. Low fiber fractions (1–5%) were investigated. The composites showed a slight lowering of thermal stability when evaluated by thermogravimentric analysis. X-ray diffraction and differential scan...

The performance of different natural fibers (hemp, kenaf and bamboo) used to formulate composites with an alkali-activated matrix based on metakaolin is evaluated. Short were randomly dispersed up about 3% the binder weight, fresh cured properties derived determined. Up investigated fraction, it still possible obtain adequate workability without supply additional water or additives. Upon modifi...

Kenaf fiber-polyester composites incorporated with powdered activated carbon (PAC) were prepared using the vacuum-assisted resin transfer molding (VARTM) process. The product demonstrates the electromagnetic interference (EMI) shielding function. The kenaf fibers were retted in a pressured reactor to remove the lignin and extractives in the fiber. The PAC was loaded into the freshly retted fibe...
