Abstract
The polyfunctionalization of cotton textiles for outdoor applications has been successfully achieved through the incorporation of complexes involving monochlorotriazine β-cyclodextrin (mono-CT β-CD) and essential oils of peppermint and clove, resulting in the creation of aromatic and UV protective ensembles. The β-cyclodextrin (β-CD) derivative was synthesized in vitro, followed by rigorous characterization and solubility testing to ensure its compatibility with water-based applications. To confirm the successful functionalization, the textiles were subjected to thorough characterization using techniques such as H-NMR and thermogravimetric analysis, verifying the attachment of inclusion complexes of mono-CT β-CD and essential oils onto the fabric. Furthermore, the release kinetics of the native aromatic oils from the cotton textiles were investigated, revealing superior retention of peppermint over that of clove. The impact of inclusion complexes on the release behavior and wash durability of essential oils was also assessed, demonstrating a significant enhancement in aroma retention, compared to unfunctionalized textiles. Additionally, the UV protection properties of the peppermint oil-treated cotton textiles exhibited improved performance against electromagnetic radiation in comparison with their untreated counterparts, further highlighting the efficacy of the polyfunctionalization process for enhancing both fragrance and UV protection in outdoor textiles.
