Effect of Onion (Allium cepa L.) Peel Extract-based Nanoemulsion on Anti-microbial and UPF Properties of Cotton and Cotton Blended Fabrics

ABSTRACT

The new technologies and materials necessary for the development of antibacterial fabrics have been of great interest to researchers in recent years. This study focuses on the investigation of the natural waste product such as onion peel-based nanoemulsion for dyeing of cotton and cotton blended fabric samples. 100% cotton and polyester/cotton fabrics have been dyed with two different concentrations (5% and 10%) of onion peel (OP) extract-based nanoemulsion (NE). Antibacterial activity of dyed samples has been tested against both the Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative) bacteria. Among all the fabric samples, the 100% cotton fabric dyed with 10% onion peel-based nanoemulsion (OP-NE) registers the highest antibacterial activity of 75 and 57% against S. aureus and E. coli, respectively. However, the antibacterial effectiveness remained substantial at 38 and 31%, respectively, even after 25 home laundry washes. The test specimens have been further tested for their color strength, ultra-violet protection factor (UPF), tensile, and tear strength properties to evaluate the change in their physical properties.

摘要

近年来, 开发抗菌织物所需的新技术和新材料引起了研究人员的极大兴趣. 本研究主要针对洋葱皮基纳米乳液等天然废弃物对棉和棉混纺织物样品进行染色的研究. 100%棉和聚酯/棉织物已使用两种不同浓度(5%和10%) 的洋葱皮 (OP) 提取物基纳米乳液 (NE) 进行染色. 染色样品的抗菌活性已对金黄色葡萄球菌 (革兰氏阳性) 和大肠杆菌 (革兰氏阴性) 进行了测试. 在所有织物样品中, 用10%洋葱皮纳米乳液 (OP-NE) 染色的100%棉织物对S.奥里斯和E.大肠杆菌. 然而, 即使在25次家庭洗衣后, 抗菌效果仍分别保持在38%和31%. 进一步测试了试样的颜色强度、紫外线保护系数 (UPF)、拉伸强度和撕裂强度性能, 以评估其物理性能的变化.
