Textile fibers represent a large part of the amount of solid waste generated, mainly coming from the cutting sector in the confection. Most of the textile waste is made of polyester. One way to reuse discarded polyester is by re-obtaining the basic components for its formation, such as terephthalic acid, from the depolymerization process. Terephthalic acid can be used as a starting material for the synthesis of metalorganic frameworks, which are highly crystalline and porous structures and may have various properties, such as antibacterial. This work aimed to synthesize the MetalOrganic (MOF) Cu (BDC) structure from terephthalic acid from the polyester recycling process and apply it to polyester fabric. The obtained materials were characterized by x-ray diffractometry, infrared spectroscopy, NMR spectrum, microbiota and colorimetric analysis. With this it was possible to verify the purity of the recycled terephthalic acid, the formation of the MOF crystallites, their presence in the polyester fabric, and the proof of the 99.8 inhibition percentage on the growth of microorganisms caused by the MOF. The obtained results made it possible to verify the presence of MOF in the fabric even after washing, indicating the potential of the proposed textile finishing using economical and environmentally viable technology.
