Influence of Sodium Hydroxide Treatment on Typha domingensis Fibers for Geotextile Manufacturing
Summary
Researchers investigated how sodium hydroxide treatment affects the mechanical properties of Typha domingensis plant fibers used for erosion control geotextiles. They found that the chemical treatment improved fiber strength and durability during biodegradation testing on experimental slopes. The study suggests that treated natural fibers could serve as a sustainable, biodegradable alternative to synthetic geotextiles that contribute to microplastic pollution.
The conservation of soil, a finite natural resource, demands effective measures. Within this context, the instability of soil masses on steep slopes poses significant risks to human life and environmental infrastructure, highlighting the need for developing erosion control strategies rooted in soil bioengineering principles. The objective of this study was to investigate the mechanical properties of Typha domingensis fibers subjected to biodegradation and treated with sodium hydroxide (NaOH) for geotextile manufacturing. Experimental slopes were employed to mimic natural environmental degradation conditions. The Typha domingensis fibers underwent treatment with alkaline NaOH solutions at concentrations of 3, 6, and 9% and were exposed for 180 days. Samples were collected every 30 days to evaluate the degradation process and performance under these conditions. These fibers exhibited resilience against field degradation over a period exceeding 180 days, demonstrating sustained effectiveness. Despite an initial reduction in strength compared to untreated control fibers, the treated fibers displayed enduring stability throughout the experimentation. This suggests that 6% NaOH concentration may yield higher tensile strength, thus positioning it as the optimal choice for the production of biodegradable geotextiles derived from Typha domingensis fibers.
