Chemical and instrumental characterization of maturing kenaf core and bast

Industrial Crops and Products, 1999
Abstract 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.

Dioxane lignins of kenaf bast and tow

Chemistry of Natural Compounds, 1979
1. Dioxane lignins have been isolated from the outer (bast) and inner (tow) parts of kenaf of the variety Uzbekskii 15–74, and the semiempirical formulas of the phenylpropane structural units of these dioxanes have been calculated on the basis of elementary and functional analyses.

Kenaf bast cellulosic fibers hierarchy: A comprehensive approach from micro to nano

Carbohydrate Polymers, 2014
Cellulosic fibers from kenaf bast were isolated in three distinct stages. Initially raw kenaf bast fibers were subjected to an alkali pulping process. Then pulped fibers undergone a bleaching process and finally both pulped and bleached fibers were separated into their constituent nanoscale cellulosic fibers by mechanical shearing.

Multi stage peroxide and activated peroxide bleaching of kenaf bast pulp

Carbohydrate Polymers, 2013
Soda-anthraquinone kenaf bast pulp (12.5 kappa number and 32% ISO brightness) has been bleached with multi stage peroxide bleaching process. Bleaching process was carried out in different sequences of peroxide stage without and with activator (tetraacetylethylenediamine, TAED) to about 80% ISO brightness.

Viscoelastic Properties of Kenaf Bast Fiber in Relation to Stem Age

Textile Research Journal, 2009
Natural fibers traditionally used for cordage are proving valuable for advanced industrial applications due in part to beneficial physical and chemical properties, but also because they are a renewable and biodegradable resource. Kenaf ( Hibiscus cannabinus L., Malvaceae) produces high yields of lignocellulosic bast fibers in the bark layer, and is a ...

Weibull distribution analysis of the tensile strength of the kenaf bast fiber

Fibers and Polymers, 2016
This paper presents the influence of the gage length on the kenaf fiber Young’s modulus and the tensile strength characterization. Four different gage lengths of 10 mm, 15 mm, 20 mm and 25.4 mm are selected in this study and the tensile testing is performed at a quasi-static loading rate of 1 mm/min.

Varieties of Kenaf (Hibiscus cannabinus), a Bast Fiber Plant, in Cuba

Botanical Gazette, 1945
1. The species of Hibiscus being grown in Cuba for the production of soft fiber has been correctly identified as kenaf (H. cannabinus) rather than as roselle (H. sabdariffa). Differences in color of withered flower petals and seed characters, as well as unlikeness in various floral parts and in the appearance of stems, are suggested means of ...
