The chemical composition of several non-woody plant fibers (bast fibers from flax, hemp, kenaf, jute; leaf fibers from sisal, abaca and curaua; and giant reed), which are used as raw materials for pulp and papermaking, has been evaluated. Particular attention was paid to the composition of the lipophilic compounds and the structure of the lignin polymer since they are important components of th...

With an ultrasonic frequency of 15 kHz and 850 W power capacity, the effects nanosilica particle inclusion on tensile, flexural, impact properties woven fiber-reinforced kenaf/carbon fiber/epoxy hybrid composites were explored experimentally. The nanoparticles dispersed uniformly in epoxy using probe. Test samples made according to ASTM requirements for three distinct weight compositions partic...

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...

the present research has been conducted to investigate the soda and soda-anthraquiuone pulping from whole kenaf (v36). in this respect, anatomical characteristics of kenaf bast and core fibers as well as the soda and soda-aq pulp properties produced at four sodium hydroxide concentrations, namely 25, 30, 35 and 40 (g/lit), have been evaluated. the pulping results indicated that pulp yield and k...

The feasibility of cultivation of kenaf (Hibiscus cannabinus) in the United States is receiving a multifaceted evaluation. Among the factors being evaluated is kenafs susceptibility to nematodes. In this investigation, four races of Meloidogyne incognita reproduced extensively on each of the several kenaf genotypes examined in greenhouse tests. Some genotypes of kenaf, however, demonstrated lim...

In this study, powdered activated carbon (PAC) was produced from agricultural waste biomass of kenaf (Hibiscus cannabinus L.) core or stalk, and the process variables were optimized by applying central composite design (CCD). The influences of carbonization temperature, duration of activation, and impregnation ratio on removal percentage of copper Cu(II) ions from aqueous solution and carbon yi...

Kenaf (Hibiscus cannabinus) from the family Malvaceae, is a valuable fiber plant native to India and Africa and is currently planted as the fourth commercial crop in Malaysia. Kenaf seed oil contains alpha-linolenic acid, phytosterol such as β -sitosterol, vitamin E, and other antioxidants with chemopreventive properties. Kenaf seeds oil (KSO) was from supercritical carbon dioxide extraction fl...
