Abstract

There is a growing demand for dyed cotton fabrics for antibacterial and UV-resistant materials application. Here, we use titanium dioxide (TiO2) to improve the UV resistance and impart self-cleaning property to cotton fabrics. Besides, to produce antibacterial dyed fabrics, berberine hydrochloride is used as a dye and antibacterial agent. Phytic acid and berberine hydrochloride are coated onto the fabrics via self-assembly to improve the light fastness. Scanning electron microscopy and Fourier-transform infrared spectroscopy tests show that TiO2 nanoparticles are grafted onto fabrics, and phytic acid (–) and berberine hydrochloride (+) are successfully assembled onto the fabric surface. The treated fabrics exhibit excellent UV light fastness and good self-cleaning property. Most importantly, the obtained cotton fabrics illustrate remarkable antimicrobial activity against Staphylococcus aureus and Escherichia coli O157:H7 with 97.63% and 84.52% bacterial reduction within 60 min of contact time, respectively. Therefore, our designed dyed antibacterial fabrics may have great potential for use in textiles.

Highlights

Natural plant dyes come from a wide range of sources, and some of them have many advantages, such as aromatic smell, antimicrobial effects, and health benefits
Owing on its natural compound, excellent antibacterial efficacies, and broad-spectrum sterilization, we introduced berberine to prepare dyed antibacterial fabrics
After further assembly with phytic acid (PA) and berberine hydrochloride (BH), more particles appeared on the surface. This result indicated that the Butanetetracarboxylic acid (BTCA)/TiO2-PA/BH was coated onto the cotton fabric surface and uniform distribution was present on the surface

Summary

Introduction

Natural plant dyes come from a wide range of sources, and some of them have many advantages, such as aromatic smell, antimicrobial effects, and health benefits. The treated cotton fabrics had deeper color and showed excellent UV light fastness compared with the contrast samples. After coating with BTCA and TiO2, the cotton fabric surface showed many nanoparticles and was relatively uniform in distribution.
