| dc.description.abstract | Typha leaf fibers are potentially useful resources in the fiber engineering field. Chemical extraction was a common method to extract fibers from the Typha leaves. However, depending on the extraction protocol, the fibers obtained might be less regular with a wider range of diameters. The leaves might react with the alkaline solution to a varying extent and fiber products with inconsistent quality might be formed. This research investigated the morphology of fibers from manual and chemical extraction. The presence of calcium oxalate plates on a number of fibers indicated that lacunae fiber (also called fiber cable in literature) could be one type of extracted fiber in the chemical extraction, but whether it was the only type of extracted fiber was not clear. Lacunae fibers could be manually extracted from the leaves by removing the surrounding leaf materials. A manual extraction method was designed and explained in this research. The manually extracted lacunae fibers had the surface morphology of nodes and calcium oxalate plates. The node might be the remainder of the diaphragm in the leaf structure. Chemical treatment using potassium hydroxide solution for the manually extracted lacunae fibers was able to reduce the mean and variance of fiber diameters. The post-extraction process was important for both manual and chemical extraction as it could affect the quality of the fibers and should be further investigated. This research found that extracting the lamina, leaf sheath, and leaf sheath without the dorsal and ventral surface chemically produced fibers with different colors. | en_US |
