Fibrous based materials with exceptional functionalities have become a target of interest for researchers worldwide. One promising strategy for the development of active fibrous structures with improved functions is their functionalization with nanoparticles (NPs). In this work, jute fabrics were functionalized with calcium oxide (CaO) and silica (SiO₂) NPs in order to obtain fibrous structures with several properties including, hydrophobicity, UV protection, antibacterial activity and the degradation of dyes ability. CaO and SiO₂ NPs were synthesized via a simple in situ method, using sodium hydroxide (NaOH) as the reducing agent and water as solvent. Parallelly, the in situ synthesis of the CaO NPs was also tested. The final systems were fully characterized using Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy, Ground-State Diffuse Reflectance and Field Emission Scanning Electron Microscopy and Energy Dispersive Spectroscopy. All these techniques confirmed the successful synthesis of the NPs as well as their well distributed presence onto the fabrics. The samples exhibited very good contact angle values, reaching 143.7° for the fabrics functionalized with CaO and SiO₂ NPs and great values of ultraviolet (UV) protection factors (UPF), reaching 50+ for the functionalized fabrics. The developed systems also exhibited antibacterial activity against Staphylococcus aureus and Escherichia coli and photocatalytic activity for the degradation of methylene blue. The wash durability of the nanocoating was also evaluated, confirming that the SiO₂ improved the NPs’ anchorage onto the fabrics. Overall, this work presents for the first time, the development of jute fabrics with CaO–SiO₂ NPs with several functionalities.

具有卓越功能的纤维基材料已成为全球研究人员的关注目标。开发具有改善的功能的活性纤维结构的一种有前途的策略是它们被纳米颗粒（NP）官能化。在这项工作中，将黄麻织物用氧化钙（CaO）和二氧化硅（SiO ₂）NPs功能化，以获得具有多种特性的纤维结构，这些特性包括疏水性，防紫外线性，抗菌活性和降解染料的能力。CaO和SiO ₂NP通过简单的原位合成方法合成，使用氢氧化钠（NaOH）作为还原剂，水作为溶剂。同时，还测试了CaO NP的原位合成。使用衰减全反射傅里叶变换红外光谱，基态漫反射和场发射扫描电子显微镜以及能量色散光谱对最终系统进行了全面表征。所有这些技术证实了NP的成功合成以及它们在织物上的良好分布。样品显示出非常好的接触角值，使用CaO和SiO ₂功能化的织物达到143.7°NP和紫外线（UV）保护因子（UPF）的价值很高，功能化织物达到50+。开发的系统还显示出对金黄色葡萄球菌和大肠杆菌的抗菌活性以及对亚甲基蓝降解的光催化活性。还评估了纳米涂层的耐洗性，证实了SiO ₂改善了NPs在织物上的固着性。总体而言，这项工作首次展示了具有多种功能的CaO–SiO ₂ NP的黄麻织物的开发。
