Abstract
Every person has a natural body odour, which may lead to low self-esteem, embarrassment, and even affecting interpersonal relationships. The use of antibacterial fabric offers a potential solution to this problem. Thus, this study introduces a novel approach by utilizing pomegranate rind extract (PRE) as an antibacterial agent to optimize sol-gel and green synthesis parameters for producing antibacterial particles designed for fabric coatings. The problem addressed is the need for an efficient, ecofriendly, and economical synthesis method to fabricate antibacterial coatings for fabrics. The research focuses on the effects of precursors; copper oxide particles (CuO) and magnesium oxide particles (MgO) and synthesis methods on the antibacterial properties of the synthesized particles coated onto cotton, polyester, and blend wool fabrics. The alkaloid, phenolic, and polyphenols compounds which act as antibacterial agent were identified in pomegranate rind extract (PRE). The presence of CuO and MgO elements in respective particle’s solution was confirmed by X-Ray Fluorescent (XRF). The solgel method produced smaller particle with the size of 325.9 nm (CuO) and 317.7 nm (MgO) compared to green synthesis method (CuO, 374.5 nm; MgO, 325 nm). Scanning Electron Microscopy (SEM) images showed uniform coating surfaces for MgO-coated cotton fabrics, while CuO particles exhibited small agglomerations. Meanwhile, nonhomogenize and non-uniform depositions of particles were observed in all coated polyester and coated blend wool fabrics. The Energy Dispersive X-Ray (EDX) spectra has verified the presence of MgO particles and CuO particles in the coated fabrics. Antibacterial testing demonstrated the effectiveness of MgO particles against grampositive bacteria (B. linens, C. acnes, and S. epidermidis) for all fabric types. In the meantime, the highest antibacterial activity was observed (7 mm) against B. linens on CuO-coated cotton fabric synthesized via sol-gel method. Tensile strength was influenced by fabric type and coating synthesis method, with the highest increment of tongue tear strength was 33.73 % in warp direction and breaking load was 13.59% (warp direction) and 10.67% (weft direction) observed for CuO-coated cotton fabrics synthesized via green synthesis. Air permeability decreased in MgO-coated cotton fabrics synthesized via sol-gel method (42.82%), while CuO-coated polyester fabrics showed the highest increment of 12.01%. The durability of the coatings varied, with the MgO particles from sol-gel method exhibiting better washing durability. Gas Chromatography-Mass Spectrometry (GC-MS) analysis revealed the presence of volatile organic compounds (VOCs) in uncoated cotton (phosphoric acid, hexanoic acid, and octanoic acid), uncoated polyester (ethyl carbamate), and uncoated blend wool fabric (acetic acid). However, none of the VOCs were detected in all coated fabrics, indicating effective prevention of bacteria-causing body odour. Owing to the coating uniformity, antibacterial properties, washing durability and the increment in air permeability and tensile strength, the MgO particles synthesized via sol-gel method and coated onto cotton fabric were identified as the most effective antibacterial coated fabric. The knowledge gained from this study demonstrates the potential of PRE in the synthesis of antibacterial particles. This research contributes to the field by providing a sustainable and effective method for producing antibacterial fabric coatings. Further research can focus on enhancing the antibacterial properties and durability in order to produce high quality antibacterial coated fabrics.
