KENAF MATS - PROPERTIES OF NONWOVEN MATS FROM KENAF FIBER

Raw kenaf fiber consists of coarse bundles of ultimate cells (fibers) held together by lignin and pectins. These fibers must be refined for easier refining through nonwoven equipment. Kenaf was treated with sod ium hydroxide to partially extract lignin and separate the fiber bundl es. The concentration and duration of sodium hydroxide treatment were varied to determine optimum conditions. Treated kenaf fibers were open ed, carded, and then needlepunched into sturdy nonwoven mats containin g 100% kenaf or kenaf/cotton blends. Blended mats of kenaf/cotton reta ined more oil than mats prepared from polypropylene fibers. Other pote ntial applications for these biodegradable mats include prevention of soil erosion, weed control, and the cleanup of waste liquids.
