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.

Structural color is an important way to achieve the ecological coloring of textiles. SiO 2 microspheres with sizes in the range of 200–337 nm were synthesized by the Stober method and then covered with highly light-absorbing melanin PDA to form SiO 2 @PDA photonic crystals. The SiO 2 @PDA photonic crystals were assembled onto the surface of white cotton fabrics by gravity deposition to achieve structural color. The addition of polyvinylpyrrolidone (PVP) enhances interfacial bonding by forming multiple hydrogen bonds between its lactam group and the phenolic hydroxyl group of PDA, resulting in a structured color cotton fabric with high color fastness. Scanning electron microscopy (SEM) was used to study the structure and morphology of SiO 2 @PDA microspheres. The chemical compositions of PDA and PVP were surveyed by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The surface structural color of cotton fabrics was investigated by UV–Vis reflectance spectroscopy.

Multifunctional textiles have attracted widespread attention with the improvement of awareness of health. Especially, the fluorine-free superhydrophobic and conductive cellulose fiber-based fabrics have received intensive interest due to their broad and high-value applications. Herein, the copper sulfide nanoflowers were in-situ deposited on cotton fabric followed by polydimethylsiloxane (PDMS) treatment for encapsulating CuS nanoflowers and obtaining superhydrophobicity, recorded as Cot@PTA@CuS@PDMS. Cot@PTA@CuS@PDMS possesses superhydrophobicity with contact angles of 153.0 ± 0.4°, photothermal effect, excellent UV resistance, good conductivity, and anti-fouling. Interestingly, the resistance of Cot@PTA@CuS@PDMS is significantly reduced from 856.4 to 393.1 Ω under simulated sunlight irradiation with 250 mW/cm 2 . Notably, the resistance can be slightly recovered after shutting off simulated sunlight. Besides, Cot@PTA@CuS@PDMS has efficient oil-water separation efficiency for corn germ oil and castor oil, respectively. Briefly, this work provides a novel, facile, and promising strategy to fabricate multifunctional fiber-based textiles with the reversible change of resistance under simulated sunlight irradiation, inspiring more scholars to control the resistance change of textiles by light irradiation.

To obtain cotton fabrics with high-efficiency flame retardancy, a novel nanohybrid MXene modified with phosphorylated chitosan (CS) was successfully prepared through a simple chemical modification strategy. It was subsequently employed in the fabrication of PC@T-MXene-functionalized cotton fabric (PC@T-MXene-C) through an impregnation process. The thermal stability and flame retardancy of the pure and treated cotton textiles were analyzed via TGA, LOI, VBT flammability tests and cone calorimetry. Compared with those of the original cotton textile and PCS-decorated cotton fabric (PC-C), the thermal and flame-retardant performance of PC@T-MXene-C was significantly enhanced. When the weight gain of the treated cotton fabric was 12 % (PC@T-MXene-C3), the LOI of PC@T-MXene-C3 significantly reached 35 %, and the peak heat release rate (PHRR) and total heat release (THR) decreased by 80.7 % and 43.7 %, respectively, compared with those of the original cotton textile. Additionally, PC@T-MXene-C3 retained 39.1 % of the char residual at high temperature under a nitrogen atmosphere in the TGA analysis. This eco-friendly biomass-based flame-retardant coating provides a new strategy for fabricating green flame-retardant systems without the use of hazardous compounds.

In order to solve the problems of high energy consumption, high raw material consumption and poor air permeability of fabrics in the dip-baking method, a simple low-liquid inkjet printing method was used to prepare superhydrophobic cotton fabrics. Inkjet printing technology enables precise control over the printing position and droplet amount, allowing for the creation of superhydrophobic patterns on the fabric surface. ZIF-8 precursor solution and long alkyl chain siloxane were formulated as suitable inks and printed on the surface of the fabric, forming a rough interface with low surface energy. The surface micromorphology and chemical structure of the fabric samples were characterized in detail. The prepared ZIF-HDTMS-cotton fabric exhibited superhydrophobic property with a high water contact angle of 158° and self-cleaning property against liquid and solid contaminants. Importantly, after undergoing a variety of harsh damage tests, the modified fabric still exhibited good superhydrophobicity, indicating its favorable chemical stability and mechanical durability. Compared to raw cotton fabric, the treated fabric exhibited an air permeability rate of 311.6 L/m 2 /s, proving its excellent breathability. Due to the high absorption capacity of ZIF-8 to ultraviolet rays, the prepared cotton fabric has obtained a certain ultraviolet protection effect. In addition, through infrared camera observation, it is found that the ZIF-HDTMS-cotton fabric also has a good anti-permeation effect on hot water, which can play a role in preventing scalding. These findings pave the way for the development of patterned multifunctional textiles through precise inkjet printing technology.

A durable superamphiphobic cotton fabric was obtained by coating SiO2 aerogel particles, polydimethylsiloxane (PDMS), and 1H,1H,2H,2H-perfluorooctyltriethoxysilane (PFTES) on a cotton fabric via the dip-pad-dry process. The surface morphology, chemical composition, and thermal degradation behavior characterization of the as-prepared cotton fabric (PFTES/PDMS/SiO2@Cotton fabric) were performed, respectively. It was proved that the coated cotton fabric was successfully covered with PFTES/PDMS/SiO2. The porous rough surface topology structure due to the SiO2 aerogel particles along with low surface energy because of the fluorinated chains and PDMS adhesive layer on the as-obtained PFTES/PDMS/SiO2@Cotton fabric can trap a layer of air, endowing the coated fabric durable superamphiphobicity. The prepared superamphiphobic cotton fabric with a water contact angle (WCA) of 159.0 ± 0.8° and an oil contact angle (OCA) of 154.5 ± 0.7° showed good liquid repellence for common liquids in daily life like orange juice, cola, coffee, and milk, exhibiting excellent self-cleaning and stain-resistance property. Moreover, the superamphiphobic cotton fabric possessed good durability and still maintained superamphiphobicity after mechanical abrasion for 1500 cycles or ultraviolet (UV) irradiation for 96 h. This superamphiphobic cotton fabric exhibited potential applications in various fields due to the high repellency to various liquids.

The facile construction of a cotton fabric with excellent flame-retardant and water-proof abilities is of great interest for multitask requirements. Herein, a nonfluorine, highly efficient, and cost-effective multifunctional cotton fabric was fabricated via sequentially depositing a novel multielement-containing flame-retardant phosphorylated octa-aminopropyl POSS (PPA-POSS) and a fluorine-free superhydrophobic coating of zeolitic imidazolate framework-67@poly(dimethylsiloxane) (ZIF-67@PDMS). Influences of the PPA-POSS concentration and ZIF-67@PDMS formula on the fire retardancy and water repellency of treated cotton were systematically investigated. The optimized flame-retardant sample CTF3 with 6.2 wt % PPA-POSS exhibited a high limiting oxygen index (LOI) of 34% and self-extinguishing ability. CTF3 was further modified with a properly formulated superhydrophobic ZIF-67@PDMS coating. CTF3-PHB2 displayed enhanced thermal stability, flame retardancy, and outstanding superhydrophobicity. Thermogravimetric analysis (TGA) results demonstrated that CTF3-PHB2 presented a high char residue of 35.9%, which was 220.5% higher than that of the control cotton (11.2%). More importantly, the heat release rate (HRR), total heat release (THR), and average effective heat of combustion (av-EHC) values of CTF3-PHB2 were significantly reduced by 51.4, 56.2, and 68.4%, respectively, compared with those of a pure cotton fabric. Moreover, CTF3-PHB2 showed superhydrophobicity (WCA > 159.3°) and good mechanical abrasion resistance. In addition, CTF3-PHB2 also showed protective abilities such as antifouling, self-cleaning, and water/oil separation performances even for strong acid/alkali mixtures. Thereby, it is believed that the PPA-POSS@ZIF-67@PDMS coating is promising for application in multifunctional textile materials.

The preparation of hydrophobic surfaces has been extensively studied, but the reversible responsive hydrophobic surface has received less attention. In this paper, poly(styrene-random-methyl methacrylate-random-acrylic acid) (P(St-r-MMA-r-AA)) was prepared by conventional free radical polymerization, and the filter paper and cotton fabric were immersed in P(St-r-MMA-r-AA) methanol solution to construct a hydrophobic surface. The hydrophobic property, chemical composition and surface morphology of the hydrophobic filter paper and cotton fabric surface were characterized by contact angle, Gibbs free energy, infrared spectroscopy and scanning electron microscopy. The optimum conditions for constructing hydrophobic filter paper and cotton fabric surface were investigated. When the surfaces of hydrophobic filter paper and cotton fabric were treated with methanol, tetrahydrofuran and deionized water respectively, the semihydrophobic-hydrophobic-hydrophilic reversible transformation could be achieved. After ten cycles of experiments, the contact angles under the three solvent stimulations had no significant change, and the hydrophobic properties of the hydrophobic cotton fabric were superior to that of hydrophobic filter paper. The Gibbs free energy calculation of the hydrophobic surface indicated that the change in surface hydrophobic property was due to the inversion between the hydrophobic PS segment, the PMMA segment, and the hydrophilic PAA segment.

In this work, a highly efficient flame retardant and electromagnetic interference (EMI) shielding coating on cotton fabric was fabricated by a simple solution impregnation and dip-coating method, which involved three layers of polyacetimidate (PEI), ammonium polyphosphate (APP), and Ti3C2Tx. When exposed directly to flame, the PEI/APP coating lead to a char layer resulting in self-extinguishing performance. Particularly, the cotton fabric coated by increasing amounts of Ti3C2Tx gradually achieved EMI shielding performance. When the Ti3C2Tx sheets content was 5.2 mg/cm2, a high electrical conductivity of 670.3 S·m–1 and a EMI shielding effectiveness of 31.04 dB were achieved in the X-band with an absorption-dominated mechanism. Besides, such modified cotton fabric also has the potential to be used as an electrical heating material. The temperature could even reach up to about 64.3 °C under an applied voltage of just 4 V. Therefore, this work provided a feasible idea for preparing multifunctional fabrics.

Cellulose is a natural material with dissolution-regeneration property and numerous hydrogen bonds in the molecule. By utilizing these properties, this paper reported the development of a multi-functional fabric consisting of cellulose and commercial cotton fabric. The morphology, mechanical and thermal properties along with the oil-water separation performance of the developed material were studied. The results showed that the cellulose dissolved in NaOH/urea solution was regenerated in a salt solution, and attached tightly onto the cotton fabric, forming a sandwich structure for the material. Such modification significantly enhanced the strength, thermal stability and hydrophilic performance of the fabrics. Interestingly, the prepared material exhibited a unique underwater oleophobic performance, and had the capability to separate highly emulsified oil-water mixtures. The relatively low cost for the material preparation, enhanced mechanical property and high separation performance distinguished the developed material a suitable candidate for the separation of emulsified oil from water in practical applications.

Extensive research and practice on anti-crease of cotton fabric has been made in the past few decades because of its easy creasing properties. However, it has not achieved a good balance between anti-crease performance, strength loss, hydrophilicity and formaldehyde release until now. In this study, for the first time, α-lipoic acid (ALA) which contains bifunctional groups, carboxyl group and disulfide bond, has been successfully used as an innovative cross-linking agent in the anti-crease functionalization to prepare high crease resistant and hydrophilic cotton fabric without strength loss and formaldehyde release. The mechanism between ALA and cellulose through esterification, disulfide breaking and reconstruction, and anti-crease mechanism based on topological disulfide bridges among cellulosic molecules were illustrated in terms of the characterization analyses of cross-linked ALA and poly(α-lipoic acid). This study provides a completely different idea for the preparation of anti-crease cotton fabric with high strength and hydrophilic without negative environmental impact.

Chitosan oligosaccharide (COS), a water-soluble carbohydrate obtained from chemical or enzymatic hydrolysis of chitosan, has similar structure and properties to non-toxic, biocompatible, and biodegradable chitosan. However, COS has many advantages over chitosan due to its low molecular weight and high water solubility. In the current work, COS was incorporated in the laccase-catalyzed polymerization of hydroquinone. The laccase-catalyzed polymerization of hydroquinone with or without COS was investigated by using simple structure of glucosamine hydrochloride as an alternative to COS to understand the mechanism of COS-incorporated polymerization of hydroquinone. Although polyhydroquinone can be regarded as the polymeric colorant with dark brown color, there is no affinity or chemical bonding between polyhydroquinone and cotton fibers. Cotton fabrics were successfully in-situ dyed into brown color through the laccase-catalyzed polymerization of hydroquinone by incorporating with COS as a template. The presence of COS enhanced the dye uptake of polyhydroquinone on cotton fibers due to high affinity of COS to cotton and covalent bonding between COS and polyhydroquinone during laccase catalysis. This novel approach not only provides a simple route for the biological coloration of cotton fabrics but also presents a significant way to prepare functional textiles with antibacterial property.
