Multifunctional Finishing of Cotton Fabric with Curcumin Derivatives Coatings Obtained by Sol–Gel Method

Abstract

Textile materials with fluorescent, repellent, or antimicrobial properties are increasingly used in common applications. Obtaining multi-functional coatings is of wide interest, especially for applications related to signaling or to the medical field. In order to increase the performance (color properties, fluorescence lifetime, self-cleaning or antimicrobial properties) of textile materials with special uses, a series of research was carried out regarding the modification of surfaces with nanosols. In this study, coatings with multiple properties were obtained by depositing nanosols on cotton fabrics generated through sol–gel reactions. These multifunctional coatings are hybrid materials in which the host matrix is generated using tetraethylorthosilicate (TEOS) and network modifying organosilanes:dimethoxydimethylsilane (DMDMS) or dimethoxydiphenylsilane (DMDPS) in a 1:1 mass ratio. Two curcumin derivatives were embedded in siloxane matrices, a yellow one (CY) that is identical to bis-demethoxycurcumin (one of the natural constituents in turmeric) and a red dye (CR) that has a N,N-dimethylamino group grafted in position 4 of the dicinnamoylmethane skeleton of curcumin. The nanocomposites obtained by embedding curcumin derivatives in siloxane matrices were deposited on cotton fabric and studied in relation to the dye and the type of host matrix. Fabrics coated with such systems provide a hydrophobic surface, have fluorescent and antimicrobial properties, change color depending on the pH, and therefore can be used in various fields where textiles provide signaling properties, self-cleaning, or antibacterial protection. The coated fabrics maintained their good multifunctional properties even after several washing cycles.

Therapeutic textiles: A promising approach for human skin dysbiosis?

“…In this sense, a range of therapeutic textiles, namely those with antimicrobial activity, have been developed. [31][32][33][34][35][36] However, most of them are still limited to in vitro evaluation, and only a small portion effectively translated to clinical trials. But when translated to clinical studies, the macroscopic evaluation has received special consideration, while the microscopic effects have been poorly investigated.…”

“…Additionally, another key point regarding the development of therapeutic textiles with antimicrobial activity to target skin dysbiosis is the composition of such products; unfortunately, most of them comprise synthetic or metallic antimicrobial agents, which, despite being very effective against a range of microorganisms and providing durable effects on textiles, are a concern due to health hazards, action on non‐target microorganisms and environmental pollution 37,41 . Consequently, the incorporation of natural bioactive compounds, such as fish oil, curcumin, chitosan, resveratrol and others, has emerged as safe alternatives due to their non‐toxic, non‐allergic and biodegradable nature combined with antimicrobial potential 32,42,43 . Thus, the replacement by natural agents should be a top priority during the design of therapeutic textiles providing innovative and sustainable products with antimicrobial, antioxidant and anti‐inflammatory properties.…”

Enhancing Therapeutic Efficacy of Curcumin: Advances in Delivery Systems and Clinical Applications

“…The resulting coatings exhibited hydrophobicity, fluorescent and antimicrobial properties, as well as pH-dependent color change. These multifunctional coatings retained their properties even after washing cycles, offering potential applications in textiles requiring signaling, self-cleaning, or antibacterial properties [ 106 ].…”
