Description

A name used for both a banana-like plant (Musa textilis) as well as the strong fibers obtained from its leaf stems. The plant is native to the Philippines. It was exported to Europe and elsewhere in the 19th century and is now cultivated in Central America. Abaca fibers contain cellulose and lignin (~7%). Formerly known as Manila hemp, the fibers are lustrous and range in color from cream to light purple to brown or black. The texture of the fibers vary from silky to stiff. Abaca fiber is extensively used for rope, especially in marine environments since it is buoyant and does not swell in water. Coarse fibers are used for heavy cordage, twine, hats, hammocks, manila paper, and tissue paper. Fine, glossy fibers of abaca, called pinukpok or lupis, are used to make fabric for carpet, tablecloths, placemats, purses, rugs and ethnic costumes. Waste fibers are used to produce papers with high wet strength, such as tea bags.

Musa textilis; Manila hemp; Manilla hemp (Br.); abacá (Esp., Port.); manila; pinukpok; lupis; agotai; cebu hemp; davao hemp; abaka;

Other Properties

Does not swell or lose strength in water. Fiber length = 1 - 5 m (3-15 feet). Denier ranges from 300-500

Paper fiber type: Non-woody/bast. Using transmitted light microscopy, fibers are identified by their uniform shape, thin walls, and pointed ends. Fibers are relatively short with a wide, well-defined lumen. Appearance with Graff "C" stain: Nodes will stain red. Average dimensions of fibers: length, 5-6mm. 20-24μm wide. Common pulping method: alkaline sulfite.

Hazards and Safety

Combustible, but self-extinguishing.
