Jute, kenaf, and ramie are important fiber crops in the textile industry, but their core stalks have not been well used. In this study, three fiber crops were examined with enhanced hexoses yields (% cellulose) up to 4.8-, 3.6-, and 1.9-fold from enzymatic hydrolysis of the steam-exploded stalks. Sequential dilute acid/alkali pretreatments achieved the increased hexoses yields up to 7.6-, 4.8-,...

currently deficiency of raw materials and initiative resources caused an increasing need of cellulose industries to new lingo cellulose products and resources. kenaf as a fibrous plant is considered along with the other plant sources that their bast has suitable fiber. this experiment was carried out in split–plot form with 4 replication in order to evaluation effect of harvest time and genotyp...

Kenaf (Hibiscus cannabinus L. ), a warm-season annual plant, has shown potential as an alternate source of fiber in the United States. Although preliminary research has indicated feasibility ofkenaf production in Virginia, production details are lacking. Field experiments were conducted during 1995 and 1996 to determine optimal row spacing and fertilizer needs, and to compare available kenaf cu...

This paper investigates the energy absorption response of winding kenaf fiber composite tubes when subjected to an axial quasi-static crushing test. The square composites were prepared firstly by submerging the kenaf yarn into resin bath before it is warped around the mould for different number of layers and fiber orientations. The parameters measured were peak load, mean load and specific ener...

The present work study flexural and tensile behavior of short Kenaf fiber reinforced composites. The fibers are chemically treated in 2% NaOH solution at room temperature. Short fibers of 4mm and 8 mm are used in the present work. The composite lamina is prepared by hand molding using isopthalic polyester resin. Flexural test and tension tests are carried out as per ASTM standards. The flexural...

The objective of this research was to evaluate the properties of the chemically retted kenaf bast fiber impregnated with the inorganic nanoparticles. High quality kenaf bast fibers were obtained from a chemical retting process. An in situ inorganic nanoparticle impregnation (INI) process was used to introduce the CaCO3 nanoparticles into the retted kenaf bast fibers. It was found that some of t...

Kenaf fiber extracted from kenaf stem bast is an important natural fiber. The genetic basis of yield and quality poorly understood. In the present study, Fiber phenotypic data showed continuous positive distribution or positively skewed distribution. traits its related including plant height, fresh weight, dry weight a correlation. However, there was negative correlation between count. results ...

Kenaf (Hibiscus cannabinus L.) is an economically important natural fiber crop grown worldwide. However, only 20 expressed tag sequences (ESTs) for kenaf are available in public databases. The aim of this study was to develop large-scale simple sequence repeat (SSR) markers to lay a solid foundation for the construction of genetic linkage maps and marker-assisted breeding in kenaf. We used Illu...

Sandwich structure composites produced by epoxy core and aluminium skin were developed as potential building materials. Interface bonding between core and skin was controlled by varying kenaf content. Five different weight percentage of kenaf loading ranging from 10 wt% to 50 wt% were employed in the core manufacturing in order to study the mechanical properties of the sandwich composite. Prope...

Two experiments were conducted to determine the dietary value of pellets containing kenaf (Hibiscus cannabinus cv. 'Everglade 41') hay. Averaged across both experiments, kenaf pellets contained 82.6% kenaf hay, 16.6% liquid molasses, and 0.8% mineral oil. The chemical composition of the kenaf pellet was 12.6% crude protein (CP), 41.2% neutral detergent fiber (NDF), and 14.4% acid detergent fibe...
