Description	In this work, a visible-light-driven $BiOCl/Bi_{2}WO_{6}$ photocatalyst was obtained via a facile hydrothermal method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS), X-ray photoelectron spectroscopy (XPS), ultraviolet/visible light diffuse reflection spectroscopy (UV/Vis), and photocurrent (PC). $BiOCl/Bi_{2}WO_{6}$ was modified with (3-chloro-2-hydroxypropyl) trimethyl ammonium chloride to obtain the cationized $BiOCl/Bi_{2}WO_{6}$. Cotton fabric was pretreated with sodium hydroxide (NaOH) and sodium chloroacetate solution to obtain carboxymethylated cotton fabric, which was further reacted with cationized $BiOCl/Bi_{2}WO_{6}$ to achieve finished cotton fabric. The cotton fabrics were characterized by Fourier-transform infrared spectroscopy (FT-IR), XRD, SEM, and EDS. The photocatalytic activity of the $BiOCl/Bi_{2}WO_{6}$ photocatalyst and cotton fabrics was assessed by photocatalytic degradation of MB (methylene blue) solution under simulated visible light. The self-cleaning property of cotton fabrics was evaluated by removing MB solution and red-wine stains. Results revealed that the coated cotton fabrics exhibited appreciable photocatalytic and self-cleaning performance. In addition, anti-UV studies showed that the finished cotton fabrics had remarkable UV blocking properties in the UVA and UVB regions. Therefore, the finished cotton fabric with $BiOCl/Bi_{2}WO_{6}$ can provide a framework for the development of multifunctional textiles.
