Investigation of the Extraction Processes and Performance Properties of Kudzu Fibers

Abstract

Kudzu plants have become increasingly invasive in the US, yet are not highly utilized. Intending to produce eco-friendly fibers, this research used fresh kudzu vines to produce fibers by four different processes: boiling, retting, enzymatic and mild chemical processes. Two types of fibers resulted from each process – soft and woody. Unlike more popularly used natural bast fibers such as linen, there is no standard description of the surface structure of kudzu fibers established, this report provides a broad microscopic analysis and images for kudzu fibers. Resultant kudzu fibers, with an average length of 20–300 cm, exhibited a breaking load of 4–20 kg/tex and a breaking elongation of 22.67–37.94%. Results suggest that soft kudzu fibers are promising for apparel and use in fiber-reinforced composites while woody fiber as basketry or paper.
