摘要

The growing need for antimicrobial textiles, especially in healthcare, faces challenges due to the environmental and safety concerns surrounding traditional antimicrobial agents. This study tackles the persistent issue of microbial contamination in textiles, focusing on the critical need for infection control in wound care. A green solution is offered: harnessing the power of nanotechnology and abundant biomass. Nanobiochar (nBC)– a super-fine material crafted from readily available, lacustrine agroforestry coconut shell waste– is employed, and functionalized, to create textiles with added benefits. The approach involves gently embedding cotton fabric with nBC through an optimized dip-coating method, fine-tuning nBC concentration, temperature, and dipping cycles. The fabric is then infused with the essence of chocolate mint. Characterization using SEM, FTIR, and XRD revealed a clear link between the amount of nBC loaded onto the fabric and the optimized process settings. A higher nBC loading, especially at 5% concentration, 95 °C, and 7 cycles, created a beautifully textured, porous fabric surface brimming with nBC, and bestowing excellent antimicrobial properties. Tests against common bacteria showed that the more nBC the fabric held, the better it fought off bacteria. Sterility tests confirmed no lingering microbes. This confirms successful manufacturing of the nBC and embedding it in the fabric. This offers a sustainable and biocompatible option for wound dressings, medical textiles, and beyond– ushering in a new era of eco-conscious functional fabrics.
