Plant derived natural fibers have been widely investigated as alternatives to synthetic fibers in reinforcing polymers. Researchers over the years have explored many plant fibers using different extraction processes to study their physical, chemical, and mechanical properties. In this context, the present study relates to the extraction, characterization, and optimization of Typha angustata L. stem fibers. For this purpose, desirability functions and response surface methodology were applied to simultaneously optimize the diameter (D), linear density (LD); yield (Y), lignin fraction (L), and tenacity (T) of Typha stem fibers. Typha stems have been subjected to both alkali (NaOH) and enzymatic (pectinex ultra-SPL) treatments. Three levels of process variables including enzyme concentration (10, 15, and 20 ml/L) and treatment duration (10, 15, and 20 days) were used to design the experiments according to the factorial design. Experimental results were examined by analysis of variance and fitted to second order polynomial model using multiple regression analysis. The Derringer's desirability function released that the values of process variables generating optimized diameter, linear density, yield, lignin ratio and tenacity are 20 ml/L and 20 days for concentration of pectinex ultra-SPL enzyme and treatment duration, respectively. Confirmation was performed and high degree of correlation was found between the experimental and statistical values. Moreover, the morphological structure has been investigated by the scanning electron microscope, showing a crenelated structure of ultimate fiber bundles of cellulose composing the Typha fiber. Compared to Typha stem non-treated fibers (TSNTF), Typha stem combined treated fibers (TSCTF), brings to improve mechanical properties. This change in mechanical properties is affected by modifying the fiber structure showing alpha cellulose of (66.86%) and lignin ratio of (10.83%) with a crystallinity index of (58.47%).

“…Properties of fibers extracted from different varieties of Typha leaves and provided by different extraction processes were characterized. Extracted from different varieties and regions of the world, Typha leaf fibers revealed a lignocellulosic structure compared to other natural fibers such as jute, kenaf, agave, and hemp [7].…”

Cattail (Typha), a wetland plant, is emerging as a sustainable materials resource. While most of the Typha species are proven to be a fiber‐yielding crop, Typha latifolia exhibits the broadest leaf size (5–30 mm), yields highest amount of fiber (≈190.9 g), and captures maximum CO2 (≈1270 g). Alkaline retting is the most efficient degumming process for cattail fibers to achieve maximum fiber yield (30%–46%). Cattail leaves exhibit a distinctive bionic structural model consisting of epidermis and leaf blade at macro level and non‐diaphragm aerenchyma, fiber cables, partitions, and diaphragms at micro level. Cattail fibers hold promise to be utilized as a high‐performance composite part and as efficient energy storage devices in clean energy vehicles. The former is attributed to their lower density (≈1.26–1.39 gm/cm3) and higher tensile modulus (≈66.1 GPa after treatment), while the latter is attributed to their porous structure and chemical stability. Therefore, integrating the knowledge of plant biology and materials chemistry is crucial for enhancing fiber characteristics and producing engineered bioproducts. The environmental benefits of cattails, degumming methods, leaf and fiber structures, their properties and applications is reviewed. Finally, it discussed future research directions aimed at developing bioengineered, biodegradable products from it with minimal environmental impact.
