In recent years, an unprecedented increase in the development of products and technologies to protect the human being has been observed. Now, more than ever, the world population is exposed to several threats, harmful to their well-being and health. Chemical and biological hazardous agents stand out as one of the biggest threats, not only for the military forces, but also for the civilians. Consequently, it's essential to develop personal protective systems that are able to protect their user, not only passively, but actively, being able to detect, adsorb, degrade and decontaminate pesticides, pollutants, microorganisms and most importantly: chemical/biological warfare agents. One recent strategy for the development of active fibrous structures with improved functions and new properties is their functionalization with nanoparticles (NPs), especially metal oxides. Although their known effectiveness in the decomposition of harmful agents, the NPs could also include other functionalities in the same structure using low quantities of material, without adding extra weight, which is of huge importance for a soldier in the battlefield. The use of natural fibers as the substrate is also very interesting, since this material is a much sustainable alternative when compared to synthetic ones, also providing excellent properties.
近年来，人们观察到用于保护人类的产品和技术的发展出现了前所未有的增长。如今，世界人口比以往任何时候都更容易受到多种威胁，这些威胁对他们的幸福和健康有害。化学和生物危险制剂是最大的威胁之一，不仅对军事力量，对平民也是如此。因此，开发能够保护使用者的个人防护系统至关重要，这种保护不仅是被动的，而且是主动的，能够检测、吸附、降解和净化农药、污染物、微生物，最重要的是：化学/生物战剂。开发具有改进功能和新特性的活性纤维结构的一种最新策略是用纳米颗粒（NPs）对其进行功能化，特别是金属氧化物。尽管纳米颗粒在分解有害制剂方面具有已知的有效性，但它们也可以在相同结构中使用少量材料包含其他功能，而不增加额外重量，这对战场上的士兵来说非常重要。使用天然纤维作为基材也非常有趣，因为与合成纤维相比，这种材料是一种更具可持续性的选择，同时还具有优异的性能。
