In this research, a series of graphene‐based conductive textiles is developed by three different coating methods, including dip‐coating (D), airbrushing (A), and filtration (F). The cellulose substrate consists of a blend of cotton and rayon fabric, and the coating formulation is based on a mixture of graphene powder as a conductive filler, polyurethane (PU) as a binder, and poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) as a thermoplastic co‐binder. The thermogravimetric analysis (TGA) results are used to prove an enhancement in the thermal stability of the coated fabrics. The graphene content of the coated samples is also estimated from the char residue at 800 °C of the TGA profiles. The graphene‐based coating converts the water‐adsorbing cellulose fabric to a hydrophobic surface as the water contact angle raises from 0° to more than 107° after coating. The mechanical properties of the plain cellulose fabric enhance considerably in terms of tensile strength and tensile modulus, where the highest improvement is seen in the Dip‐coating method, with an 89% increase in tensile strength compared to cellulose fabric. The graphene‐based coating developed in this work enhances the physical, thermal, mechanical, and conductivity properties of the plain cellulose substrate. The resulting coated fabrics can be potentially used in wearable smart electronic textiles.

“…In recent years, the use of chemical substances that contain fluorine (fluorochemicals) to produce water-repellent textiles has been recognized for its effectiveness on almost all textiles [1,4]. Furthermore, technologies such as lasers, gamma irradiation, critical CO 2 , plasma, ultrasound, ultraviolet irradiation, ozone, and nanobubbles (e-Flow) are attracting significant academic and industrial interest as alternatives to conventional wet finishing processes [2,5,6].…”

Recently, a significant interest in eco-friendly textile products and processes has been noted among consumers and producers. In this respect, nanobubble technology is emerging as a green alternative. In this study, water-repellent cotton fabrics were produced with exhaustion and nanobubble technology (e-flow method) using a short-chain fluoropolymer. The currently most developed substituents are based on molecules with short fluorine carbon chains. The wettability, mechanical properties, air permeability and treatment durability were evaluated. The untreated and treated cotton fabrics were analyzed with ATR-FTIR (Fourier transform infrared attenuated total reflectance) and SEM (scanning electron microscopy) to reveal chemical and morphological modifications. The obtained results show that cotton samples treated with short-chain fluoropolymers, nontoxic and eco-friendly finishing chemicals, and nanobubble technology have good water repellence and good washing durability. Due to their size and structure, nanobubbles possess distinct properties that make them particularly effective at improving water quality, enhancing water treatment processes, and improving productivity in industrial applications. Nanobubbles have a strong negative surface charge that keeps them stable in liquid, prevents them from coalescing, and enables them to physically separate small particles and droplets from water, such as emulsified fats, oils, and grease.

“…To achieve easy-care performance, especially for crease recovery and retention, different commercial finishing methods and chemicals were developed such as formaldehyde-based easy-care finishes (dimethyloldihydroxy-ethylene urea-DMDHEU) [6], ether derivatives of DMDHEU [7], formaldehyde-free finishes with polycarboxylic acids (1,2,3,4-butane tetracarboxylic acid, citric acid, maleic acid, succinic acid etc.) [8], carboxyl polyaldehyde sugars [9] applied by finishing treatment, foaming [1], and sol-gel technology [10].…”

In this study, cotton fabrics were treated with temperature-water responsive nanocomposites consisting of shape memory polyurethane (SMPU) and cellulose nanowhiskers (CNWs), for smart crease recovery/retention functions besides breathability with dynamic porosity. The smart crease recovery/retention functions were determined in air/water at different temperatures and relative humidity simulating laundry and drying processes and air permeability test was conducted at different fabric temperatures. Also, physical-mechanical properties (weight, thickness, bending rigidity, and strength) and washing fastness properties were evaluated. Fourier-transform infrared (FT-IR) and scanning electron microscope (SEM) analyses confirm the SMPU-CNW nanocomposite presence on fabric. Test results show that the treated cotton fabrics have not only dual responsive shape memory properties providing smart permeability, but also dynamic crease recovery/retention with enhanced mechanical properties. This method could contribute t ecological and economic aspects of sustainability as a result of less energy and polymer consumption with non-ironing property and treatment procedures and low chemical footprint.
