在纺织品中使用环糊精等生物聚合物来开发生物功能织物是开发环保纺织品的替代方案。环糊精可以与羊毛中的化学基团产生共价相互作用，从而吸附释放的活性分子，例如香茅油。因此，本工作研究了应用于羊毛中的环糊精复合油的形成及其释放机制。获得复合物并接枝到织物上。除了验证整理的耐久性和所得织物的细胞毒性之外，还使用 TGA、DLS、FTIR-ATR 和 SEM 等仪器对形成的新微观结构进行了表征。还使用 Korsmeyer-Peppas 提出的方法分析了香茅油的释放并进行了数学调整，以验证释放机制。根据 FTIR-ATR 光谱和 SEM 图像，结果表明复合物的形成及其通过共价键的固定，显示出非菲克但受控的释放曲线。因此，该复合物在羊毛织物中的应用为设计和生产受控释放的环保生物功能材料提供了有前景的选择，从而使油特性可用于纺织基质中。
The use of biopolymers such as cyclodextrin in textiles for the development of biofunctional fabrics is an alternative for the development of eco-friendly textiles. Cyclodextrins can create covalent interactions with the chemical groups available in wool, allowing the sorption of active molecules that will be released, such as the citronella oil. Therefore, this work investigates the formation of cyclodextrin complex oil applied in wool and its release mechanism. The complexes obtained and grafted to the fabric. New microstructures formed have been characterized using instruments as TGA, DLS, FTIR-ATR and SEM, besides the verification of the durability of the finish and the cytotoxicity of the obtained fabric. The release of citronella oil was, also analyzed and mathematical adjustments were performed using the approach proposed by Korsmeyer-Peppas in order to verify the release mechanisms. Results have indicated the formation of the complex and its fixation by covalent bonding, according to the FTIR-ATR specter and SEM images, have shown an non-fickian, but controlled, release profile. For this reason, the application of the complexes in wool fabrics shows promising options for the design and production of eco-friendly biofunctional materials for controlled release, allowing the oil properties to be used in textile matrices.
