Fabrics were flame-retardant finished using phytic acid, a cost-effective, ecologically acceptable, and easily available flame-retardant finishing chemical. Then, on the surface of the completed fabric, silver nanoparticles (Ag NPs) were grown in situ to minimize Ag NPs aggregation and heterogeneous post-finishing and to increase washing durability. Thus, flame-retardant and antibacterial qualities were added to textiles. The as-prepared textiles were evaluated for their combustion performance, thermal performance, and antibacterial capabilities. At the same time, their microstructures were studied using X-ray diffractometry (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). The findings indicated that flame-retardant textiles had an excellent launderability (limiting oxygen index = 31% after 20 washing cycles). Meanwhile, Ag NPs-loaded flame-retardant textiles demonstrated self-extinguishing properties, with a limiting oxygen index (LOI) of 27%. Bacteriostatic widths of flame-retardant antibacterial textiles againstEscherichia coliandStaphylococcus aureuswere 5.28 and 4.32 mm, respectively, indicating that Ag NPs-loaded flame-retardant fabrics have certain flame-retardant and antibacterial capabilities. SEM and TEM analysis indicated that nanoparticles were uniformly dispersed over Ag NPs-loaded flame-retardant textiles and were around 20 nm in size. When compared to flame-retardant textiles, Ag NPs-loaded flame-retardant fabrics showed varied binding energy of P and N on the surface and Ag ion emergence. Thermogravimetric analysis at various heating rates revealed that the main pyrolysis temperature range of flame-retardant fabrics decreased, while the main pyrolysis temperature range of Ag NPs-loaded flame-retardant fabrics increased; the heating rate influenced the pyrolysis range but not the fabric mass loss. In situ reduction synthesis of Ag NPs-loaded flame-retardant textiles may successfully reduce agglomeration and heterogeneous dispersion of nano-materials during post-finishing.Keywords:antibacterial treatment;phytic acid;flame-retardant cotton textiles;Ag NPs

Modification of cotton fabric with 2-methacryloyloxyethyltrimethyl ammonium chloride (DMC) was achieved through free-radical initiated graft polymerization with K2S2O8/NaHSO3as the initiator. Grafting of DMC was confirmed by ATR-IR of the modified cotton. The optimal grafting reaction conditions, including DMC dosage, mole ratio of initiator to DMC, temperature, and time, were determined by cation content and dye fixation results of the modified cotton. The modified fibers were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and whiteness measurement. Salt-free dyeing of the modified cotton with commonly used C. I. Reactive Blue 19, C. I. Reactive Yellow 145, and C. I. Reactive Red 195 presented high fixation of 96.8%, 98.7%, and 97.3%, respectively. These results indicated that the modification is effective for changing the surface charge of the fiber and increasing the dye-fiber reactivity. The color fastness and strength property were still very satisfactory. With excellent properties, this dyeing method shows promise in real application for eliminating the usage of salt and reducing environmental pollution.Keywords:cotton fabric;modification;reactive dyes;graft copolymerization;salt-free dyeing

Supercapacitors have a rapid charge/discharge rate, long lifespan, high stability, and relatively acceptable cost, showing great potential in energy storage and conversion applications. However, the current cost-effective carbon-based electrodes have limited application owing to their low specific capacitance and unsatisfactory stability. In this regard, we herein prepare nitrogen-doped carbons by carbonizing a mixture of cotton pulp (CCP) and melamine to improve the specific capacitance by integrating pore (mesopore) and surface (oxygen-containing groups) modification with defect engineering via the carbonization process. Furthermore, the structural and morphological features of the resultant nitrogen-doped carbons are confirmed by various characterization techniques. Excitingly, the specific capacitance for nitrogen-doped CCP (CCPN1) with a 1 : 1 weight ratio of CCP and melamine is 642 F g−1 at a current density of 0.5 A g−1 in a three-electrode system, surpassing that of the reported carbon analogues and most metal-based materials to date. The stability test suggests that the specific capacitance of CCPN1 is maintained over 150 F g−1 at a current density of 2 A g−1 even over 5000 cycles. Therefore, the reported nitrogen-doped carbons from cotton pulp exhibit improved specific capacitance and stability, providing a new cost-effective carbon-based material for application in the energy storage field.

The design of multifunctional, high-performance wearable heaters utilizing textile substrates has garnered increasing attention, particularly in the development of body temperature and health monitoring devices. However, fabricating these multifunctional wearable heaters while simultaneously ensuring flexibility, air permeability, Joule heating performance, electromagnetic interference (EMI) shielding and antibacterial properties remains a significant challenge. This study utilizes phase transition lysozyme (PTL) film-mediated electroless deposition (ELD) technology to deposit silver nanoparticles (Ag NPs) on the cotton fabrics surface in a mild aqueous solution at room temperature, thereby constructing a wearable heater with long-term stability, high conductivity, and exceptional photothermal properties. The textiles enriched with Ag NPs exhibit remarkable electrothermal and photothermal dual-driven heating capabilities, achieving temperatures exceeding 110 °C within 50s under 2 V, or in merely a few seconds through photothermal conversion. Importantly, these textiles retain the intrinsic flexibility and breathability of the textile substrate. Furthermore, the amyloid-like protein Ag NP integrated textiles demonstrate excellent antibacterial properties, and exhibit a high EMI shielding efficiency of 50 dB within the frequency range of 8.2–12.4 GHz. Therefore, these multifunctional Ag NPs wearable heaters were expected to find applications in areas such as smart wearable clothing and future health management.

The infection caused by Fusarium oxysporum severely threatens cotton production. Herein, carvacrol-chitosan nanoparticles (CS@CAR) are facilely fabricated using tripolyphosphate as a crosslinker. When the initial mass ratio of chitosan to carvacrol is 1:0.4, the nanoparticles show the best stability and drug loading. Morphological analysis reveals that the CS@CAR nanoparticles possesses a uniform spherical structure with an average diameter of approximately 150 nm. About 51.23 % of total CAR is released within the 48 h in the simulated fungal infection environment. The contact angle of drug-loaded particles decreases by 12.2 and 6.6 ° compares with that of pure water and unloaded particles. The fluorescence intensity of leaves before and after rain erosion is 1.3 times and 1.2 times that of the pure water control group by fluorescence imaging analysis. The bacteriostatic activity of drug-loaded nanoparticles is 6–7 times that of non-drug-loaded nanoparticles. The contents of nucleic acid, protein, and malondialdehyde leaked by spores after treatment with drug-loaded particles are 1.4, 1.5 and 2.3 times those in the non-drug-loaded particle treatment group, respectively. The CS@CAR entirely prevents Fusarium oxysporum from infecting cotton leaves in spore inoculation experiments. The CS@CAR nanoparticles are expected to be used to prevent and control the infection of Fusarium oxysporum on cotton.

Single-mode personal thermal-moisture management fabrics cannot ensure the comfort and safety of the human body in high-temperature, high-humidity, and complex environments. Here, a tri-cooling cotton fabric (TCCF) that combines evaporation, convection, and heat storage with a converging pore array, Janus wetting structure and phase change microcapsule is demonstrated. Benefiting from its Janus wetting structure and converging pore array, the TCCF exhibits excellent unidirectional sweat-wicking performance (717 unidirectional transfer index) and rapid water vapor transmission (223.0 g/m 2 /h). The TCCF can lower the temperature by 4.5 °C through evaporation and convection compared with conventional cotton. Furthermore, the TCCF demonstrates excellent buffering capacity for sudden temperature changes. Evaporation, convection, and heat storage help cool the human body in complex environments.

Herein, we report a cooling fabric with thermal conduction and radiative cooling capabilities through grafting hydroxylated boron nitride (BN-OH) nanosheets onto the surface of cotton fibers. The thermal conduction layer formed by BN-OH nanosheets enables the modified fabric with excellent thermal conductivity, which is 42% higher than that of the original cotton fabric. Resulting in the modified fabric exhibits great cooling power and increases the cooling setpoint temperature by 1 °C, which corresponds to reduced 11.2% indoor cooling energy consumption. Additionally, the Mid-infrared emissivity and solar reflectivity are increased to 90% and 70.4%, respectively, suggesting that wearing modified fabric under direct sunlight can enable the artificial skin to avoid overheating by 7.8 °C compared to bare skin. Moreover, the modified fabric also presents a considerable contact cool feeling, impressive wearability, and durability. We expect this work to present new insights for the design of personal thermal management textiles. Graphical abstract

The study reports a tactic for superior antibacterial performance on cotton via synergism of complementary functionalities of quaternary ammonium salt and malonylurea-based N -chloramine combined in a silane. Knoevenagel Condensation between 4-(chloromethyl)benzaldehyde and malonylurea formed a product whose chloromethyl group was used to quaternize tertiary amine of N , N -dimethylethanolamine. The O − H of the quaternization product was subsequently alcoholyzed with Si − H of trimethoxysilane. The methoxysilyl groups of the alcoholysis silane were hydrolyzed to silanol ones that condensed with either their own kind or hydroxy groups of cellulose to polymerize into a crosslinked polysiloxane finishing on cotton. Upon chlorination of malonylurea-based N − H bonds, each repeating unit of the polysiloxane has one quaternary ammonium salt and two imide N -chloramine sites. Antibacterial assays against Staphylococcus aureus and Escherichia coli proved that the synergism of quaternary ammonium salt and N -chloramine, a higher efficacy and a broader spectrum arising from their complementary elimination mechanisms and physiochemical features. Biocidal stability and rechargeability of the polysiloxane finishing were both promising due to the robust and hydrophobicity of silicone backbone and the sturdy cyclic N -chloramine. This research presented a general approach for generation of super biocidability on substrates that can react with hydroxy group using silanes to carry complementary functionalities.

The antibacterial silver nanoparticles (Ag NPs)-loaded cotton fabric modified by SPEEK/PVA film was prepared by photo-induced method with 350 nm UV light irradiation. Its wearable properties, such as wrinkle recovery, tensile property, thermal stability and water vapour permeability were investigated. It was found that the fabric loaded with Ag NPs retained its brown colour after five cycles of washing in soap solution. TG/DTG analysis indicated that the fabric had two pyrolysis peak temperatures at about 370 °C and 500 °C, and the loading of Ag NPs improved the thermal stability of the cotton fabric. The crease recovery angles of the fabric in both warp and weft directions increased with the generation of Ag NPs. However, both the breaking force and elongation at break decreased with the generation of Ag NPs due to the use of UV irradiation, which is destrimental to the mechanical performance of textile materials. Moreover, the deposition of Ag NPs led to a minor decrease of the water-vapour transmission rate. The hand-feel evaluation showed that the softness of the fabric improved whilst the smoothness declined with the loading of Ag NPs. The water contact angle was found to be 135.2°, indicating that the Ag NPs-loaded cotton fabric had excellent hydrophobicity.

With the rapid development of industry and the increasing discharge of oily wastewater, there is a growing interest in superhydrophobic materials for oil-water separation and water pollution remediation. At the same time, there is an urgent need for materials capable of oil-water separation and wastewater degradation. In this paper, superhydrophobic photocatalytic cotton fabrics were prepared by introducing zinc oxide nanoparticles (ZnO NPs) on pristine fabrics (PF) to obtain a micro/nano-rough structure, octadecylamine (ODA) to provide a low surface energy, and epoxy resin (ER) used as an adhesive to enhance the adhesion between the ZnO NPs and the fabric. The prepared ODA-ZnO-ER@PF has excellent superhydrophobicity with a water contact angle (WCA) of 156.5° and self-cleaning ability. Due to its good photocatalytic properties, it can basically degrade methylene blue (MB) and rhodamine B (RB) in water after 12 h of UV irradiation. In addition, ODA-ZnO-ER@PF has excellent mechanical properties and maintains good superhydrophobicity after mechanical abrasion, ultrasonic washing, tape-peeling, UV irradiation and acid or alkali immersion. Gravity-driven oil-water separation simulation experiments indicated that ODA-ZnO-ER@PF has good oil-water separation efficiency and recyclability. This superhydrophobic, photocatalytic and mechanically durable material shows promising applications in the treatment of oil-water pollutants.

Superhydrophobic coatings have tremendous potential for cotton fabric applications in antifouling and antibacterial. Despite great scientific and industrial interest in waterproof cellulosic cotton, its application in cotton fibres has been hindered by complicated processes, templates requirement, and limitations in scale-up production. Herein, we prepared a hydrophobic coating using one-step hydrolysis of siloxane. Through the reaction of long-chain organosilanes with acid, micro/nanostructures with low surface energy were constructed on the cotton fabric surface. Notably, the coating not only imparts self-cleaning and anti-bacterial adhesion properties to cotton fabrics, but also maintains a contact angle of over 140° after treatment with acid, alkali, organic solvents and extreme temperatures. In addition, the coating can be applied to a wide range of metals, plastics and paper to provide antifouling properties. This study believes that these excellent overall properties possess enormous potential for various applications involving anti-fouling.

Petroleum pollution and industrial emissions of organic pollutants have become significant issues affecting both ecological and human living environments. High-performance oil–water separation membranes, due to their advantages such as low cost, environmental friendliness, and ease of operation, hold vast application prospects. Therefore, the development of efficient oil–water separation membranes is crucial. We propose a clever approach involving the synergistic self-assembly of chitosan (CS) and hydroxylated multi-walled carbon nanotubes (MWCNTs) on cotton fabric to construct a rough structure. Combined with hydrophilic modification using polyvinyl alcohol (PVA), not only does this enhance wettability, but it also addresses challenges related to mechanical strength and dispersibility of cotton fabric. The resulting CMF-PVA fabric performs well under challenging conditions, exhibiting excellent separation efficiency and permeance. Particularly noteworthy is that CMF-PVA achieves separation efficiencies exceeding 99.33 % for various organic substances, with a water flux reaching 35,476.52 L m −2 h −1 and a surfactant-stabilized emulsion permeance of 1199.0 L m −2 h −1 ·bar −1 . Furthermore, CMF-PVA demonstrates outstanding mechanical durability under harsh conditions and excellent acid-base resistance. This method harnesses the inherent properties of CS and MWCNT self-assembly while enhancing the material's applicability on cotton fabric through hydrophilic modification. CMF-PVA fabric is poised to enhance selectivity, efficiency, anti-pollution properties, and accessibility in oil–water separation technology.
