Abstract
Incorporating “smartness” into leathers leads to enormous value addition. One such smartness is development of scented leather. Lavender and orange oils have been microencapsulated and infused into the leather. Viscosity, opacity, and transmittance have been measured in order to optimize oil: surfactant ratio. Emulsion polymerization technique has been adopted for encapsulation of scent oils using chitosan as wall material. Percentage encapsulation efficiency, oil load and content have been studied for the encapsulated products. Lavender oil encapsulates hold better oil content and loading than orange oil encapsulates. Further, encapsulates have been characterized using particle size, surface morphology, FT-IR and TGA and results were corroborating. The encapsulated product withstands high temperature up to 500 °C and also it also shows antimicrobial activity. Encapsulated scent oils have been incorporated into leather and subjected to perception, strength, washability and diffusion coefficient studies. Thus, successful value addition to leather through incorporating of pleasant smell has been made possible resulting in “smart scented” leathers.
