American Coatings Association 2020 Abstract In the current times, the application of nanoparticles in the textile industry has become increasingly high due to the possibility of having anticipated properties, such as captivating colors, superior stability, antibacterial activity, and high-end UV-protection to the fabrics. In this study, natural herbal nanoparticles of different sizes were prepared from shade-dried leaves of Piper betle employing ball milling technique. Going forward, structural, morphological, UV-protective, and antibacterial properties of herbal nanocomposites coated on fabrics were thoroughly analyzed and interrelated with uncoated fabrics. Herbal nanoparticles were amalgamated with chitosan to make nanocomposites and are coated on cotton fabrics with the help of the pad-dry cure method. The analysis done to study physical properties of the coated fabrics, such as air permeability, crease recovery angle, tensile strength, tearing strength, thickness, and bursting strength, explicitly showed that K.

coated fabrics have better functional properties as compared to uncoated fabrics. Along the same lines, herbal nanoparticles reflected good antibacterial and UV-absorption properties as compared to uncoated and chitosan-coated fabrics. Comprehension of functional properties revealed that herbal nanoparticlecoated fabrics highlights the potential applications of Piper betle nanoparticles in protective clothing.

Introduction Nanoparticles play a critical yet unique role in an array of fields due to their unmatched properties and applications.1 A textile is an impeccable growth medium for microbial growth as it is rich in organic compounds that are appropriate for biofilm formation and sweat absorption, This, in turn, is responsible for providing moisture conditions and causing infections to humans.2–4 Commonly, Staphylococcus aureus (S. aureus) and Staphylococcus epidermidis (S. epidermidis) lead to skin infections like boils, impetigo and cellul
