Base Data: Predictive Model for the Degradation of Natural Geotextiles Based on Chemical Recalcitrance

Although alkaline treatment has been widely employed to enhance the durability of natural fiber geotextiles, considerable uncertainty persists regarding optimal protocols for soil bioengineering applications, particularly concerning the mechanistic relationship between chemical composition and temporal reliability. This work validates a hierarchical model connecting fundamental chemical composition,specifically the lignin/cellulose ratio,to Functional Service Life (FSL) at 10% probability of failure through systematic evaluation of degradation resistance in geotextiles fabricated from *Typha domingensis* fibers subjected to graded alkaline modifications.尽管碱处理已被广泛用于提升天然纤维土工织物（geotextiles）的耐用性，但针对土壤生物工程应用的最优工艺方案仍存在显著不确定性，尤其在化学组成与时间可靠性之间的机制关联层面。本研究通过对经梯度碱处理的多米尼加香蒲（Typha domingensis）纤维制备的土工织物开展系统抗降解性能评价，验证了一个层级模型，该模型可将基础化学组成（尤其是木质素与纤维素的比值）与失效概率为10%时的功能服役寿命（Functional Service Life, FSL）建立关联。
