Phytic acid's high-efficiency flame retardant and N-halamine antibacterial were synergistically applied to cotton fibers for durable antibacterial and flame retardancy. Antimicrobial flame retardant structures were characterized by H Nuclear Magnetic Resonance Spectra (NMR) and Fourier Transform Infrared Spectrometer (FT-IR). FT-IR, X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscope (SEM), Thermogravimetric (TG), Vertical Flammability Test (VFT), and Limiting Oxygen Index (LOI) were utilized to test and characterize the prepared cotton fibers. The results showed that the antibacterial flame retardant could be durably grafted on the surface of cotton fibers for a long time, and it still maintained its self-extinguishing property after 50 washing cycles, with an LOI value of 32.2 % and a damaged length of 67 mm. The N Cl bond was formed by simple bleaching treatment, which exhibited excellent bacteriostatic effect, and had a significant inhibitory effect on Escherichia coli and Staphylococcus aureus , and chlorine oxide, as an antibacterial factor, could be reactivated after long-term storage and washing. Through the systematic analysis of cone calorimetry and carbon residue, it was concluded that the flame retardant mechanism of antibacterial flame retardant was mainly condensed phase. The results of the physical property analysis of cotton fibers showed that the whiteness, air permeability, flexibility, and other physical properties of cotton fibers had no obvious change, while the hydrophilicity of the finished fibers were enhanced.

Cotton fibers are widely used in various applications due to their biodegradability, low cost, and extensive availability. The cottonseed is associated with cotton, which has a large yield. After oil extraction, the remaining cottonseed meal has a high protein content, making it a potential flame retardant for cotton fibers. This paper proposes the concept of homologous flame retardant for cotton fiber, and presents research on Cottonseed Meal Modified Flame Retardant - Homologous Durable Flame Retardant Cotton Fiber. The experiment results showed that the flame retardants CmP prepared by phosphating cottonseed meal is an effective flame retardant for cotton fiber. Both CmP1 and CmPN demonstrated self-catalytic durable grafting on the surface of Cotton fiber. Notably, the durable flame retardant CmP1-cotton and CmPN-cotton prepared by DICY catalysis exhibit superior durability and flame retardant properties, with damage lengths of 53 mm and 86 mm, respectively, and the LOI value is more than 35 %. FT-IR, XPS, and SEM results confirmed that the flame retardant was durably grafted onto the fiber surface and the superficial layer. XPS and SEM results of flame retardant cotton and char residues of TG and CCT are displayed that the two kinds of flame retardant cotton fabrics are mainly condensed phase flame retardant mechanisms, with a synergistic gas-phase effect.

Optimized management of wound exudate is pivotal in modulating the wound healing microenvironment and facilitating tissue regeneration. Conventional dressings, however, are constrained by limited absorption capacity and a slow drainage rate, frequently resulting in excessive exudate accumulation that hinders the healing process. In this study, we developed hydrophilic kapok fiber gauze (H-KG) and Janus kapok fiber gauze (J-KG) through a sustainable and scalable hydroentanglement forming process combined with chemical modification, leveraging the unique hollow tubular structure of kapok fibers. H-KG and J-KG achieved rapid absorption, high capacity storage, and efficient evaporation through synergistic wettability modulation and capillary action-enhanced liquid transport within the hollow structure. The kapok fiber-based gauze demonstrated remarkable sustainable liquid self-pumping capabilities, exhibiting a saturation absorption rate of approximately 1346% with complete liquid evaporation achieved within 1 h. In vivo experiments revealed that both H-KG and J-KG significantly mitigated wound exudate accumulation compared with cotton gauze (CG), thereby accelerating wound healing. Quantitative analysis showed that on day 12 post-treatment, the H-KG and J-KG exhibited residual wound areas measuring 48.23% and 34.41%, respectively, of CG. This work elucidated the mechanistic role of hollow fiber in exudate management while proposing an innovative wound dressing with dynamic fluid regulation capabilities.

The problems of low activity, high cost and difficulty in recycle of photocatalysts limit their practical application. Coupling photocatalyst with abundant and natural organic material is one of feasible strategies to achieve high photoactivity and low cost of photocatalysts. Herein, one-dimensional (1D) cotton fiber@ZnIn 2 S 4 (CF@ZIS)·composites with a novel core-shell structure were synthesized by coupling ZIS with inexpensive and natural abundance CF via a simple one-pot hydrothermal process. The microstructure, crystalline structures, optical properties and electrochemical property of CF@ZIS were investigated. ZIS nanosheets were in-situ attached on the CF surface, obtaining the CF@ZIS core-shell structure. This core-shell structure significantly suppressed the self-assembly of ZIS nanosheets made almost all ZIS nanosheets exposed to visible light, improving the utilization of light and meanwhile affording more reactive sites. The as-synthesized CF@ZIS showed improved photoactivity for efficient hydrogen production under visible-light irradiation. By replacing the half ZIS by cheap CF, the CF@ZIS-50 photocatalyst exhibited the optimal visible-light photocatalytic activity , which is 2 times than pure ZIS in hydrogen production. The enhanced photoactivity of CF@ZIS photocatalyst should be attributed to the uniform in-situ growth of ZIS nanosheets on the CF surface, the reduction of CF, and the intimate interface between ZIS and CF, resulting in the boosted separation and transfer of photogenerated charges. Additionally, due to the fibrous morphology of CF, the CF@ZIS photocatalyst showed excellent recoverability and photostability. This work provides a promising approach for designing highly efficient and low cost photocatalysts by using natural organic materials.

In this study, a porphyrin functionalized cotton fiber was prepared and investigated for the visual detection and efficient adsorption of cadmium (Cd 2+ ) ions in aqueous solutions. The pristine cotton fiber was first grafted with poly (3-sulfopropyl methacrylate potassium salt) (PSMP) via the surface-initiated atom transfer radical polymerization (SI-ATRP), and subsequently immobilized with 5,10,15,20-tetrakis(1-methy-4-pyridinio)porphyrin tetra(p-toluenesulfonate) (TMPyP), to form the CPT (Cotton-PSMP-TMPyP) material. The CPT was characterized by SEM, FTIR, XPS and elemental analysis, and examined for the detection and adsorption of cadmium ions. The influencing factors such as pH and the initial cadmium ion concentrations on the adsorption performances were investigated. Results showed that the cadmium ion adsorption isotherm was best fitted with the Langmuir isotherm model, with the derived maximum adsorption capacity of 0.8638 mmol/g. The thermodynamic study showed the endothermic nature of the adsorption process. In addition, the adsorption kinetics was fast with over 90% of the total cadmium ions adsorbed within 2 min. Furthermore, the distinctive color response of the CPT to the cadmium ions in aqueous solutions was clearly displayed. A linear relationship between the light absorbance of CPT-Cd (CPT adsorbed with cadmium ions) and the initial concentrations of cadmium ions was successfully established, which could be used for the fast determination of the cadmium ion concentrations in aqueous solutions.

The adsorption and diffusion behavior of polyethyleneimine with different molecular weights on cotton fibers was evaluated at a typical concentration of 1 g/L in textile industry by titration and fluorescence labeling techniques. Directly observing the penetration extent of fluorescently labelled polyethyleneimine inside the pore structure of cotton fiber by fluorescent microscopy provided the underlying mechanism for the traditional titration methods. The adsorption behavior of polyethyleneimine was shown to be highly dependent on its molecular weight. Polyethyleneimine with molecular weight of 10,000 was limited to the outermost surface of the yarn, and polyethyleneimine with molecular weight of 1800 uniformly adsorbed on the single fiber with few of them diffusing inside the fiber, while polyethyleneimine with molecular weight of 600 easily penetrated into the pores throughout the fiber cell wall. Additionally, extending the time, increasing the temperature, adjusting the pH and increasing the PEI concentration can also promote the diffusion of PEI into the fiber to a certain extent.

3D printing technology is highly regarded in the textile and apparel industry for its rapid manufacturing and customization capabilities. However, the current 3D printing materials employed in this field can limit printed fabrics with restricted flexibility and comfort, creating a notable disparity compared to traditional textiles. To address this limitation, the study focuses on utilizing cotton fibers as the raw material for 3D printing textiles. Herein, cotton fibers were dissolved in a LiCl/DMAc solvent, with the incorporation of hydroxyethyl cellulose to adjust the printability of the ink. Materials extrusion technique was employed for the printing process. This work involved optimizing dissolution, adjusting ink viscosity , and selecting post-processing methods for the printed fabrics. A comparative investigation of the wear properties of printed cellulose fabrics, cotton fabrics, and 3D printed fabrics from thermoplastic materials was conducted. The results indicate improvements in the flexibility, breathability, and moisture absorption of 3D printed cellulose fabrics compared to existing 3D printed fabrics. Additionally, these 3D printed cellulose fabrics demonstrate superior abrasion resistance when compared to cotton fabric. As a proof of concept , garments and gloves were successfully prepared using 3D printed cellulose fabrics, expanding the use of textile materials in 3D printed textiles. This innovative approach holds promising prospects for 3D printing flexible fabrics and garments.

A novel adsorbent is prepared from waste cotton fiber by a simple pyrolysis-activation process, and it can efficiently adsorb many kinds of organic pollutants (cationic/anionic dyes and antibiotics etc.). The obtained cotton-based activated carbon (CAC) with large specific surface area (3709 m 2 g −1 ) and suitable pore structure provide abundant active sites and fast channels for the adsorption of pollutant molecules. Its saturated adsorption capacities towards methylene blue, Congo Red and tetracycline hydrochloride at room temperature can reach to 2331, 7265 and 1250 mg g −1 , respectively. In addition, the optimal sample also exhibits excellent adsorption ability towards Rhodamine B (1327 mg g −1 ), methyl orange (955 mg g −1 ) and ciprofloxacin hydrochloride (824 mg g −1 ). The adsorption involves a multi-process including pore filling, Van der Waals force interaction, electrostatic attraction, hydrogen bond formation, surface complexation and π-π stacking etc. The CAC adsorbent also exhibits excellent resistance to environmental disturbances (pH, coexisting ions and multicomponent systems etc.) and good regeneration/recycling performance. This study develops a high-efficiency biomass-based adsorbent with excellent adsorption performance and application generality, which has great potential in wastewater treatment.

Oil–water mixing has brought many problems to a society, and it is of great significance to develop a simple, convenient, efficient, and durable separation material to solve the problem of oil–water mixing. In this paper, modified cottons were successfully prepared using polydopamine as the in situ mineralization site of TiO 2 nanoparticles combined with synergistic crosslinking with KH550. A large number of hydrophilic groups endowed the cotton with superhydrophilic ability, which greatly shortened its water spreading time. The prepared modified cotton could be successfully separated from oil and water, and still had a separation efficiency of 99.999% after 50 cycles. In addition, after 24 h immersion in 1 M HCl, NaOH, and NaCl solutions and 50 abrasion experiments, the modified cotton showed excellent oil–water separation ability, and the separation efficiency was above 99.990%. Successfully provided a simple preparation method to prepare high-efficiency and clean cottons for oil–water separation.

The facile preparation and well-balanced of durable flame-retardant and multi-functional textiles have become the mainstreams in both academic and industrial communities. In this work, simultaneous enhanced durable flame-retardant and antibacterial properties of cotton fibers are prepared by grafting copolymerized with ammonium vinyl phosphonate (AMVP) and vinyl antibacterial monomers (PDMAPS or DMDAAC). Comparting to the two kinds of grafted cotton fabrics (COT/AMVP-PDMAPS and COT/AMVP-DMDAAC), it is found that COT/AMVP-DMDAAC not only displays excellent durable flame retardant , the limiting oxygen index (LOI) value of 33.8% and self-extinguishing during the vertical flammability test, but also exhibits good antibacterial activity against S. aureus and E. coli with antibacterial rates of 99.10% and 82.97%, after 50 standard washing cycles (SWC). The simultaneous enhancement of the durable flame-retardant and antibacterial properties can be attributed to the coordination effect of DMDAAC and AMVP components on grafted chain. The durable flame-retardant performance is originated from the dense carbon layer by phosphate of AMVP in condensed phase and the auxiliary low-energy of chlorine radical of DMDAAC in gas phase; the durable antibacterial property is caused by the ability to destroy bacterial cell wall of quaternary nitrogen in DMDAAC. Besides, the grafted cotton fabric also reached the wearability requirements and had a good application prospect. Based on these advantages, the grafted cotton fabric with well-balanced performance can be used for flame-retardant and multi-functional textiles to avoid fire and bacterial hazards from external environment.

Nanofibers of natural cotton lines cellulose, with a degree of polymerization above 10000, were prepared by electrospinning. The effects of cellulose concentration, flow rate and electric field strength on the morphologies of the fibers were systematically investigated. Furthermore, two effective improvements on the electrospinning apparatus were made: heating the pathway between the tip of the needle and the collector instead of the needle or the collector, and covering the drum with activated cellulose flake. High quality cellulose nanofibers were obtained under the optimized spinning conditions combined with the apparatus improvements. Moreover, oriented cotton nanofibers were acquired by elevating the rotation speed of the drum collector. The wettability of the nonwoven was greatly improved compared with the original activated cellulose. The obtained nonwoven or nanofibers of the natural cotton cellulose could be potentially applied in tissue scaffolds, protective clothing and high efficient water absorbing materials etc.

The N P flame retardant ammonium salt of hydroxyethyl hexahydrotristriazine˗triphosphoric acid (AHTTPA) was prepared by a one–pot synthesis method under formaldehyde-free and solvent-free conditions. The AHTTPA was finished on the biomolecule of cotton by using the dip-roll-bake method. Nuclear magnetic resonance (NMR 1 H, 13 C, and 31 P) demonstrated that AHTTPA was successfully synthesized. The flame retardancy of AHTTPA-treated cotton was studied by limiting oxygen index (LOI), vertical flaming test (VFT), scanning electron microscopy (SEM), and cone calorimetry (CC). The results from these tests indicate that AHTTPA-treated cotton exhibited favorable flame retardancy and durability (the LOI value of 40%-treated cotton after 50 laundering cycles (LCs) was 29.8%), the flame was immediately extinguished after removal from the treated cotton, no smoldering or continued burning, the burned part formed a complete carbon frame and generally maintained its original morphology, the peak heat release rate (PHRR) and total heat release (THR) of AHTTPA-treated cotton fabric were significantly lower than pure cotton. Thermogravimetric analysis ( TGA ) results showed that AHTTPA improved the thermal stability of cotton. The breaking strength and softness of AHTTPA-treated cotton was also retained.
