Abstract
Modern dyeing strategies face developing environmental and economic challenges due to high consumption of water, ancillaries’ materials, energy, and production of large quantities of industrial pollution wastewater. Here, a promising in situ method for multi-functional and coloration of polyester fabrics by impregnation the disperse dye onto magnetic iron oxide nanoparticles (MIONP) to use as some dye-to-dye polyester fabrics with magnetic and antibacterial functionalities. The large surface area and high surface energy of the nanoparticles (NPs) could be the reason that the colored magnetic nanoparticles (MNPs) showed high affinity toward the fabrics. The un-attached dye can readily collect from wastewater by a magnet, which significantly facilitates the wastewater treatment. The morphology, crystal phase, magnetization properties and chemical structure of the fabrics were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), and energy-dispersive X-ray spectroscopy (EDX). The fastness, tensile properties, and colorimetric values of the treated fabrics were also measured. SEM and EDX confirmed the uniform distribution of the IONPs on the fiber surface. Moreover, the reflectance spectra confirmed that the IONPs had different coloring effects on the treated fabrics. Interestingly, the tensile properties of the treated fabrics were enhanced compared with the untreated fabric. The toxicity of the treated fabric was tested by MTT assay and was found to be non-toxic against wi-38 cell line. These findings suggest the potential of the proposed method in producing multifunctional fabrics with various applications, especially medical textiles.
