Influence of Anthraquinone Addition Method on Alkaline Pulping of Kenaf Bast.

Sen'i Gakkaishi, 1996
Kenaf bast was pulped by several alkaline cookings. Soda-anthraquinone pulping is superior to soda pulping and comparable to kraft pulping with respect to pulp yield and delignification ability. All of three commercial anthraquinone and its precursors were effective for kenaf bast pulping in a same level, but a little difference between kenaf bast and ...

Combination treatment of kenaf bast fiber for high viscosity pulp

Journal of Wood Science, 2000
The viscosity of kenaf bast fiber has been found to be highly sensitive and variable with different pulping methods; therefore, it is important to choose proper chemicals and conditions for pulping and bleaching of kenaf bast fiber. From several pulping experiments, a nonconventional pulping method with a combination of ammonium oxalate pretreatment ...

Improved Hydrophobicity of Macroalgae Biopolymer Film Incorporated with Kenaf Derived CNF Using Silane Coupling Agent

Molecules, 2021
Hydrophilic behaviour of carrageenan macroalgae biopolymer, due to hydroxyl groups, has limited its applications, especially for packaging. In this study, macroalgae were reinforced with cellulose nanofibrils (CNFs) isolated from kenaf bast fibres.

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

Structural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Electromagnetic shielding properties of iron oxide impregnated kenaf bast fiberboard [PDF]

Composites Part B: Engineering, 2015
The electromagnetic shielding effectiveness of kenaf bast fiber based composites with different iron oxide impregnation levels was investigated. The kenaf fibers were retted to remove the lignin and extractives from the pores in fibers, and then magnetized.

Investigating the effect of using oxygen delignification process on kenaf bast kraft pulp properties [PDF]

تحقیقات علوم چوب و کاغذ ایران, 2018
The first act to ameliorate bleaching process is the major elimination of lignin. Actually, the use of oxygen delignification stage before bleaching process is the essential stage in improving bleaching process and reducing process emission.
