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

Abstract

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.

Investigation of antioxidant, antibacterial, antidiabetic, and cytotoxicity potential of silver nanoparticles synthesized using the outer peel extract of Ananas comosus (L.)

“…The predominant polyphenolic compounds present in AC peels were gallic acid, ferulic acid, chlorogenic acid, catechin, and epicatechin [17, 18]. These polyphenolic compounds exhibit their antioxidant potential [19].…”

Bioinspiration in Fashion—A Review

“…However, the true sustainable nature of the fiber is to be questioned. While the raw material would otherwise be waste, the extraction of the cellulose and its manufacture into useable textiles requires several stages of processing, some of which involve chemicals such as hydrogen peroxide, that could be deemed harmful to the environment [24]. Additionally, the performance characteristics of the end textile are not clearly documented and may need some development.…”
