Abstract

This work aims to conduct an eco-friendly textile finishing process by applying agricultural by-products as a dye for the finishing of polyamide fabrics. A natural dye was obtained from pomegranate peel extract. Polyamide fabrics were dyed at different conditions, and four mordanting agents were tested. The finished fabrics were analyzed in terms of CIE L, a, b and color yield (K/S) values, as well as washing fastness, rubbing fastness, light fastness and antibacterial activity. Results show that pomegranate peel extract could dye polyamide fabrics. The rubbing and washing fastness of the finished samples was good. The light fastness was fair, and its antibacterial efficiency against the tested bacteria was good.

The extract is rich in phenolics, while the flavonoids constitute a small part of the total phenolic compounds (10%). This finding agrees with previous studies that have proven that pomegranate peels polyphenols essentially consist of tannins

Summary

Introduction

Vegetables and fruits play a significant part in our daily life. The request for such imperative commodities has expanded with the increase in world population [1]. Mass consumption has led to a higher generation of by-products and has created a disposal problem [2]. Vegetable and fruit by-products could be an important and profitable source of natural compounds [3]. Numerous research has shown that the generated compounds are great sources of phenolics, natural acids, sugar, colors and minerals. Some of these natural compounds exhibit bioactive functions such as antibacterial, antitumor, antifungal, antiviral, antimutagenic and cardioprotective [4,5]
