“…Zinc oxide is unique and most promising when compared to other oxides because of its semiconducting and photocatalytic activity [17]. Zinc oxide (ZnO) and synthetic polymeric bers such as PET and nylon showed excellent visible and infrared photocatalyst decomposition e ciency [18][19][20][21][22]. The selfdegradable textile-impregnated Ag@ZnO nanocomposite showed good photocatalytic degradation activity under UV-visible light.…”

Polyester (PES) textile fabrics are chemically recycled through aminolysis, and glycolysis catalyzed by nanocomposites composed of Sb (or) In-doped ZnO and g-C 3 N 4 nanocomposites prepared by the wetimpregnation method. The nanocomposites were characterized by XRD, UV-Vis, FT-IR, and SEM-EDS techniques. X-ray diffraction patterns as well as SEM EDS showed the presence of amorphous g-C 3 N 4 and doped ZnO. The extent of the optical band gaps of ZnO observed in doping with g-C 3 N 4 . The optical band gap of 3.31 eV of ZnO was reduced to 2.55 to 2.65 eV after doping with g-C 3 N 4 . SEM morphological analysis showed a sheet-like structure along with ZnO nanoparticles adsorbed on the surface of g-C 3 N 4 .Glycolysis and aminolysis of colored PES waste produced BHET and BHETA, respectively, as pure monomers in excellent yield (>90%). FT-IR, MS, 1 H, and 13 C NMR were used to con rm the formation of BHET and BHETA. HighlightsPolyester textile waste was recycled using a green catalyst made from g-C 3 N 4 and bimetallic ZnO, achieving a circular economy.The depolymerization of PES can be achieved through aminolysis and glycolysis methods using ethanolamine and ethylene glycol.Colored PES textile wastes depolymerized into colorless monomers, BHETA.

“…Such fabrics have many advantages such as washability, abrasion resistance high strength, dimensional stability, wrinkle resistance, attractive handling, and stretch resistance. On the other hand, some unwanted features have emerged such as the accumulation of static electric charge and a lack of hydrophilicity due to a poor moisture recovery capacity (0.4 percent) [1][2][3][4][5]. Polyester has been widely used as an apparel and technical textile material in the form of fabrics, films, and plastics due to its excellent mechanical and physical properties [6,7].…”

To eliminate imidacloprid insecticide from wastewater, nanocalcite was grafted onto the surface of pretreated polyester fabric. The process of seeding was followed by the low temperature hydrothermal method for the growth of nanocalcite for the functionalization of fabric. The goal of this study was to improve the hydrophilicity of the nanocalcite photocatalyst that had been grafted onto the surface of polyester fabric (PF) using acidic and basic prewetting techniques. The morphological characteristics, crystalline nature, surface charge density, functional groups of surface-modified nanocalcite @ PF were determined via SEM, XRD, FTIR, and Zeta potential (ZP), respectively. Characterization results critically disclosed surface roughness due to excessive induction of hydroxyl groups, rhombohedral crystal structure, and high charge density (0.721 mS/cm). Moreover, contact angle of nanocalcite @ PF was calculated to be 137.54° while after acidic and basic prewetting, it was reduced to 87.17° and 48.19°. Similarly, bandgap of the as fabricated nanocalcite was found to be 3.5 eV, while basic prewetted PF showed a reduction in band gap (2.9 eV). The solar photocatalytic mineralization of imidacloprid as a probe pollutant was used to assess the improvement in photocatalytic activity of nanocalcite @ PF after prewetting. Response surface methodology was used to statistically optimize the solar exposure time, concentration of the oxidant, and initial pH of the reaction mixture. Maximum solar photocatalytic degradation of the imidacloprid was achieved by basic prewetted nanocalcite @ PF (up to 91.49%), which was superior to acidic prewetted fabric and as-fabricated nanocalcite @ PF. Furthermore, HPLC and FTIR findings further indicated that imidacloprid was decomposed vastly to harmless species by basic prewetted nanocalcite @ PF.

“…Aliphatic polyamides (PAs), also known as nylon, are extremely important polymers from a commercial point of view and are obtained from polycondensation between dicarboxylic acid and diamine. − The PA market is expected to reach ∼$30 billion by 2021 because of their high thermal resistance, biocompatibility, chemical tolerance, and high mechanical properties that make them one of the most versatile engineering polymers. − Ever since the development of nylon-6,6 by DuPont in the late 1930s, there have been many attempts to modify this polymer. − Indeed, despite the advantages already discussed, one of the most desired goals has been to improve the moisture absorption properties of the polymer and the comfort of wearing the fabrics to enlarge the possible uses of these fibers with a final main application in textiles. During the past years, many processing methods were used to improve the water affinity of PA fibers like plasma treatment, physical adsorption, enzymatic hydrolysis, and chemical etching. − The main problem behind all these methods is that they consider only physical interactions between hydrophilic auxiliaries and PA chains and so the washable durability cannot be guaranteed. To solve this problem, Sun and co-workers proposed the possibility of synthesizing a novel block copolymer containing both polyamide and polyether segments .…”

Polyamides, obtained from step-growth polymerization between dicarboxylic acid and diamine, are very important polymers used in many different industrial applications. In addition to the many advantages typical of this class of polymers, among them high mechanical performances together with chemical and thermal tolerance, the absence of moisture absorption is one the main drawbacks that reduces their application. In this work, we functionalized nylon-6,6 with polyetheramine using reactive extrusion, which allows for proper reaction conditions without initiators, catalysts, or organic solvents. Fibers obtained were characterized using nuclear magnetic resonance, Fourier-transform infrared spectroscopy, differential scanning microscopy, and scanning electron microscopy. The final hydrophilicity was checked with contact angle measurements and X-ray diffraction then compared with nylon-6,6 fibers. We discovered that this modification influences also the antibacterial activity of the fibers that was studied and clearly demonstrated against Staphyloccoccus aureus and Klebsiella pneumoniae, two well-known opportunistic pathogens. The possibility to obtain a functionalized polymer that is able to maintain the high performance of nylon-6,6 together with higher hydrophilicity and antibacterial activity may pave the way to the use of this polyamide in many other industrial applications.
