As with other bast fiber
crops, hemp phloem fibers are arranged in bundles parallel to the stem axis, and are embedded in a pectic polysaccharide network.
Kenaf bast fiber
bundle-reinforced unsaturated polyester composites IV: effect of fiber loadings and aspect ratios on composite tensile properties.
Under new leadership since 2011, Kenactiv has focused its bast fiber
programs on meeting the rapidly increasing demand for nonwoven textiles--both loose fiber for laiding and as mats or "felts.
This process is usually microbial in nature, to loose and separate the bast fiber
bundles from the non-fiber fractions of the flax stem (11).
After evaluating self-support and form retention, the inclusion of kenaf bast fiber
was found to improve formability.
Patent 6767634) is said to open up bast fiber
bundles ofkenaf, flax, or jute without breaking the fibers.
The opening chapter on Africa discuses the materials Africans used to cover themselves including, wool, silk, animal skin, bark cloth, bast fiber
(from stems such as raffia palm), and cotton.
The AFT platform includes Activatl bast fiber
products and feedstocks from kenaf, flax and/or jute, which are suited to all nonwoven manufacturing processes.
Mechanically retted short kenaf bast fiber
bundle (KBFB)--reinforced unsaturated polyester (UPE) composites were fabricated.
Their topics include processing bast fiber
plants for industrial applications, fiber-matrix adhesion in natural fiber composites, polyactic acid technology, lignin-bases polymer blends and biocomposite materials, and cellulose-based nanocomposites.
CPI is partial to the shive product: "While bast fiber
provides a bit better tensile strength, shive has lower density," says CPI application design engineer Charles Weber.
In China, the textile industry covers cotton and chemical fiber spinning, printing & dyeing and finishing, wool spinning, printing & dyeing and finishing, bast fiber
spinning, silk spinning and finishing, made up textile articles manufacture, knitted fabrics and products manufacture.
