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.

A method utilizing high-performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD) has been developed and validated for the simultaneous determination of raffinose, glucose, sucrose, and stachyose in waste liquid from cottonseed processing and in byproducts including cottonseed meal. The separation was performed using a carbohydrate ES column (250 × 4.6 mm, 5 μm) and isocratic elution with acetonitrile and water (70:30, v/v). The temperature of the column oven was maintained at 35 °C. The drift tube temperature for evaporative light scattering detection (ELSD) was operated 40 °C, while the nitrogen flow was set to 1.5 L·min−1. The saccharides were separated by HPLC-ELSD within 20 min. The coefficients of determination (R2 = 0.9986–0.9999) indicate that there was a linear relationship between saccharides and the response. The limits of detection were 0.004–0.023 mg·mL−1 and the quantification range was from 0.013 to 0.080 mg·mL−1. The intraday and interday precision were from 0.05 to 0.55% and 0.20 to 0.58%, respectively. The recovery was from 102.75 ± 2.03% to 106.76 ± 2.09% and the relative standard deviations were 1.87 to 1.98%. The method exhibited good stability in determining four saccharides in cottonseed processing waste liquid and the resultant byproduct cottonseed meal. This method exhibits high separation efficiency and sensitivity, excellent precision, and simplicity, which allows determination of the high value-added product, raffinose, in cottonseed processing waste liquid and meal.

The growing demand for sustainable proteins has highlighted cottonseed meal (CSM) as a promising high-protein byproduct. Addressing the challenge of valorizing the annual global production of over 10 million tons of CSM in cottonseed processing, this study investigated the use of choline chloride-ethylene glycol deep eutectic solvent (DES-4) for efficient protein extraction from CSM while reducing toxic gossypol content. Through Box-Behnken response surface optimization, we established optimal conditions (56 °C/3 h/40% water) that achieved 86.85% protein yield while remarkably reducing bound gossypol content from 10.24 mg/g to 2.76 mg/g. Molecular dynamics simulations (MDS) revealed that DES-4 enhance protein recovery and gossypol separation through synergistic mechanisms involving stabilizing solubility, relaxing matrix structure, and disrupting complexes. The obtained protein (CSMP-E) demonstrated superior solubility, emulsifying properties, and antioxidant activity compared to alkali-extracted counterparts. Furthermore, hydrolyzed DES-extracted protein (CSMP-EH) exhibited enhanced DPP-IV inhibitory activity (IC 50 = 1.949 mg/mL), suggesting its potential for type 2 diabetes management.

This study outlined an integrated approach for obtaining several products, such as biodiesel , gossypol, sterols, raffinose, and nontoxic cottonseed meal from cottonseed via modified two-phase extraction (TPE), supercritical methanol transesterification and other technologies. The modified TPE could not only simplify the steps of separating substances, but also improve the quality of cottonseed oil and cottonseed meal. The suitable conditions of modified TPE were as follows: the petroleum ether/methanol volume rate of 1:3, the extraction temperature of 40 °C, and the extraction time of 20 min. The supercritical methanol transesterification had a favorable yield of biodiesel with shorter time. The conversion of cottonseed oil was up to 97.5% with the temperature of 270 °C, the molar ratio of methanol to oil of 40, and a reaction time of 40 min at 10 MPa. Meanwhile, with the suitable conditions, the purity of the obtained gossypol, sterols and raffinose could be got to 92.1%, 89.8% and 94.2%, respectively. This integrated biorefinery could be useful for comprehensive development and utilization of cottonseed with fewer steps and lower cost.

In this study, steam explosion pretreatment was performed in cotton stalks, leading to 5–6 folds enhancements on biomass enzymatic saccharification distinctive in Gossypium barbadense and Gossypium hirsutum species. Sequential 1% H 2 SO 4 pretreatment could further increase biomass digestibility of the steam-exploded stalks, and also cause the highest sugar–ethanol conversion rates probably by releasing less inhibitor to yeast fermentation. By comparison, extremely high concentration alkali (16% NaOH) pretreatment with raw stalks resulted in the highest hexoses yields, but it had the lowest sugar–ethanol conversion rates. Characterization of wall polymer features indicated that biomass saccharification was enhanced with steam explosion by largely reducing cellulose DP and extracting hemicelluloses. It also showed that cellulose crystallinity and arabinose substitution degree of xylans were the major factors on biomass digestibility in cotton stalks. Hence, this study has provided the insights into cell wall modification and biomass process technology in cotton stalks and beyond.

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.

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.

A novel flame-retardant ammonium salt of cholamine (methylenephosphonic acid) ethylene-organic phosphate acid (ACMPEP) with reactive -P O(ONH 4 ) 2 and OH groups was synthesized and characterized using nuclear magnetic resonance spectroscopy . The flame retardant not only could be grafted onto cotton fibers through P O C covalent bonds , but also react with each other to form poly-ACMPEP. The results showed that the finished cotton fabrics have excellent flame retardance, good stiffness and durability. The limiting oxygen index (LOI) value of 30% ACMPEP-treated cotton was 42.0%, and after 50 laundering cycles, the LOI value still had 30.0%. Thermogravimetric analysis (TGA) results showed that the decomposition temperature of treated cotton fibers in N 2 and air was 253 °C and 247 °C, lower than that of the control cotton fibers. Additionally, thermogravimetric-Fourier transform infrared (TG-FTIR) spectroscopy analysis indicated that the treated cotton fibers only released little combustible volatile during the thermal pyrolysis process. The cone calorimetry results showed that the heat release rate (HRR) and the total heat release (THR) of treated cottons were much lower than those of control cottons. The bending length increased 44.8% for the cotton fabric treated with 30% ACMPEP. The scanning electron microscopy (SEM) and the X-ray diffraction suggested that the finishing process only slightly affected the cotton fiber structure. The FTIR spectroscopy analysis confirmed the cross-linking reaction between ACMPEP molecules and cellulose . The tensile strengths of the finished cotton fabrics decreased a little. Together, the results suggested that the ACMPEP-treated cotton fabrics have excellent flame retardance and durability.

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.

Untreated natural cotton fabrics are hydrophobic due to the high content of pectin and waxes, and the fabrics need to improve the wettability by scouring for the demands of the subsequent processing such as dyeing and finishing. In this study, a new scouring method for cotton fabrics was developed by pectin hydrolase combined with Fenton system (Fe 2+ /H 2 O 2 ). The mechanism of pectin degradation by pectinase combined with Fe 2+ /H 2 O 2 was investigated. The results showed that α-1,4-glycosidic bonds of water-soluble pectin could be degraded more efficiently by pectinase hydrolysis and Fe 2+ /H 2 O 2 oxidation. The fabrics scoured with pectinase → Fe 2+ /H 2 O 2 had less wetting time (4.25 s) and higher vertical wicking height (9.80 cm) compared to the fabrics treated with pectinase alone (> 120 s, 5.15 cm). The results of bleaching and dyeing experiments indicated that the whiteness and dyeing properties of the fabrics were not negatively affected by pectinase → Fe 2+ /H 2 O 2 treatment, and the strength loss of the fabrics (11.79%) was lower than that of the fabrics with conventional NaOH treatment (20.16%). The results of the experiments in the pilot-scale machine showed that various performance indicators of the fabrics scoured by pectinase → Fe 2+ /H 2 O 2 reached the level of the conventional NaOH treatment, which demonstrated the possibility for practical application of pectinase → Fe 2+ /H 2 O 2 scouring. The cotton fabric scouring using pectinase → Fe 2+ /H 2 O 2 is an effective and feasible new method with advantages such as environmental friendliness, mild treatment conditions, and good treatment effect.

The durability and flame retardancy of cotton fabrics have been the focus of long-term research. In this paper, a method for preparing flame retardants through the direct modification of biomass was proposed, and the durable flame retardant of homologous cottonseed meal modified biomass flame retardants for cotton fabrics was achieved through biomass composition analysis and modeling. In this study, a cottonseed meal-phosphoric acid-boric acid synergistic bio-based flame retardant (CPB) was synthesized and characterized. The results of XPS and scanning electron microscope (SEM) showed that DC-CPB1 was mainly grafted on the superficial layer and surface of the fabric, and DC-CPB2 was mainly grafted on the surface of cotton fiber. In the vertical flammability test (VFT) and limiting oxygen index test (LOI), the LOI value of cotton fabric after 50 cycles of washing can reach up to 33.5 %, and the carbon damage length was reduced from 300 mm to a minimum of 69 mm, showing excellent flame-retardant performance and self-extinguishing ability. In the cone calorimetry test, the peak heat release rate (PHRR) was significantly reduced by 82.49 %, and the results of thermogravimetric (TG) analysis and thermogravimetry-infrared-mass (TG-IR-MS) test showed that CPB1 mainly had a gas phase. In contrast, CPB2 mainly had a condensed phase flame retardant mechanism. The mechanical properties of the cotton fabric remain good after treatment.
