Extraction of Valuable Compounds from Orange Peel Waste for Advanced Functionalization of Cellulosic Surfaces

The objective of this study is to explore, identify, and evaluate the bioactive compound extracted from orange peels (OP) via ultrasonic method as potential eco-friendly agent for multifunctional cellulosic fabrics/fibers. The innovative strategy involved two approaches. (1) A closely prepared surface modification procedure for the production of multifunctional viscose fibers was successfully developed by an eco-friendly in situ synthesis of Ag, ZnO, and ZnO/Ag nanoparticles (NPs) using phenolic compounds extracted from OP. The treated viscose fibers are endowed with remarkable antimicrobial, antioxidant, UV protection, as well as photo catalytic self-cleaning activity properties. (2) The microcapsulation and application of limonene extracts from OP as insect-repellent agent for application in textile field. On the basis of the resultant promoting data, the OP extract can be considered as a promising cheap source that can be employed to develop multifunctional finishing textiles. Therefore, this study introduces a novel simplified approach to design innovative cellulosic fabrics/fibers as viable materials for functional sportswear, medical, and fashion clothing using active extracts from sustainable orange peels.
