Although silicone softeners are widely used in textile processing and finishing, elasticity and wash durability improvements remain necessary. In this study, a new bifunctional hydroxysilane coupling agent (KHP) was designed and synthesized. KHP was used as a chain extender incorporated into the polyurethane segments, then reacted with linear hydroxyl silicone oil (PMX500) through a condensation reaction, resulting in a polyurethane-grafted silicone finishing agent (KHP-PU). The KHP-PU was applied to polyamide fabric using a pad-dry-cure process, and the treated fabric was systematically evaluated for surface characteristics and hand-feel properties. Results demonstrated that KHP-PU significantly enhanced the fabric's softness and elasticity while improving its mechanical and antistatic properties. Moreover, adjusting the amount of KHP in KHP-PU effectively regulates the distribution of polysiloxane segments on the fiber surface, optimizing the fabric's handle. This study provides innovative insights for designing and developing new multifunctional softeners to create advanced textile materials with enhanced consumer appeal.

Research on multi-functional fabrics is an inevitable trend in the future development of textile field. Nevertheless, the key to the development of multifunctional fabric is how to solve the problem of contradictory function combination and how to achieve the multifunctions. In this work, a novel multifunctional fabric based on cellulose/silica microcapsules was developed by using a facile and economical method. Owing to the loaded essence and hydrophobic coupling reagent and UV absorber modified silica of microcapsules, the coated fabric not only exhibited the slow-release property of fragrance, but also had the excellent superhydrophobicity and ultraviolet (UV) protection. Furthermore, this multifunctional fabric also displayed the durable superhydrophobicity and UV protection even after chemically or mechanically damaged. The development of multifunctional fabrics largely depends on the development of textile functional finishing agent and finishing technology. Therefore, it is very important to develop new functional microcapsules or finishing agent. Graphical abstract

A unique combination of cotton fabric (CF) with a mixture of EDTA and APTES Fe 3 O 4 magnetic particles was developed and utilized for the first time as an adsorbent for removing pollutants from wastewater. Initially, Fe 3 O 4 was synthesized using the co-precipitation method. Further, the surface of Fe 3 O 4 was modified by introducing amino functional groups through a reaction with APTES, resulting in Fe 3 O 4 -NH 2 . Following this, the surface of carbon fiber (CF) was altered using ethylenediaminetetraacetic acid (EDTA) to create CF@EDTA. Through the use of EDC-HCl and NHS, Fe 3 O 4 -NH 2 was attached to the surface of CF@EDTA, resulting in the final product CF@EDTA/Fe 3 O 4 . Subsequently, the prepared CF@EDTA/Fe 3 O 4 was utilized to adsorb metal pollutants from wastewater, with a thorough analysis conducted using various characterization techniques including FTIR, SEM, EDX , XRD , VSM , and XPS to study the materials. The study specifically aimed to assess the adsorption performance of our cotton-based material towards As(III) and Cr 3+ metal ions. The pH study was also performed. Results indicated that the material exhibited an adsorption capacity of approximately 714 mg/g for As(III) ions and 708 mg/g for Cr 3+ ions. The Langmuir and Freundlich models, as well as pseudo-first and second-order models were also analyzed. The Langmuir and pseudo-second-order models were found to best fit the data. In terms of regeneration and reusability, the materials showed straightforward regeneration and recyclability for up to 15 cycles. The remarkable adsorption capacity, combined with the unique blend of cotton and Fe 3 O 4 magnet, along with its recyclability, positions our material CF@EDTA/Fe 3 O 4 as a promising contender for wastewater treatment and other significant areas in water research.

It is essential to synthesize a versatile organic solvent/water separation material with excellent stability and durability. Superwetting materials, known for their multiple practical functionalities in everyday life and industrial production, have been receiving special concern for years. In this paper, the multifunctional superhydrophobic surface has been successfully prepared by coating polydimethylsiloxane (PDMS) onto three-dimensional nest-like Co-Ni layered double hydroxides (LDHs) using fabrics as a substrate (N Co-Ni LDHs/PDMS). The hierarchical nest-like structure of Co-Ni LDHs promotes the formation of abundant air cushions and enhances self-cleaning ability under liquid, which is beneficial to the efficient separation of organic solvent/water mixture. The results fabrics (superhydrophilic N Co-Ni LDHs and superhydrophobic N Co-Ni LDHs/PDMS) exhibit a high separation efficiency of 99.1 % and a flux of 11400 L m −2 h −1 for n-hexane, kerosene, cyclohexane, tetrachloroethylene and tetrachloromethane. The separation efficiency is above 99.0 % and flux is above 10200 L m −2 h −1 after 10 cycles of separation. The superhydrophobic N Co-Ni LDHs/PDMS can load 21 times its own weight and sail on water at a velocity of 60 cm s −1 . Additionally, the superhydrophobic fabrics display excellent chemical stability and mechanical durability. The as-fabricated fabrics are suitable for application in organic solvent/water separation.

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.

This research work reported a novel approach to develop flame retardant silk fabric using naturally occurring phytic acid (PA) rich in phosphorus and TiO 2 nanoparticles through a pad-dry-cure technique. A polycarboxylic acid [1,2,3,4–butanetetracarboxylic acid (BTCA)] was employed to stabilize and improve the adhesion of TiO 2 on silk surface. The flame retardancy of the treated silk fabric was determined in terms of limiting oxygen index, vertical burning, and pyrolysis combustion flow calorimetry, and the durability of flame retardancy to washing was discussed. PA and TiO 2 were found to have a joint flame retardant effect. The combination of PA, TiO 2 and BTCA was able to endow silk fabric with excellent flame retardancy, and the good flame retardant ability was kept even after 25 times of washing. The reasons for the good washing durability of the treated silk fabric were discussed. Finally, a significant condensed-phase flame retardant mechanism of the silk fabric treated with the PA/TiO 2 /BTCA system was revealed by the analyses of thermogravimetry and pyrolysis combustion flow calorimetry.

Limited robustness is a serious drawback for superhydrophobic coatings and degrades the performance of superhydrophobic surfaces in practical applications. Although fluororeagents have excellent durability for superhydrophobicity, their use has been restricted due to various health and environmental concerns. In this work, we describe a facile and efficient fabrication strategy for creating robust fluorine-free superhydrophobic composite coatings that are prepared by a simple dip-dry method, in which the H3BO3-incorporated SiO2–alkyl-silane coatings are deposited on woven cotton fabric surfaces followed by polydimethylsiloxane modification. The coated surface shows a large water contact angle of 157.95 ± 2° and a small sliding hysteresis angle (SHA) of 3.8 ± 0.6°, demonstrating excellent superhydrophobicity. The coated fabric surface also exhibited robustness and durability, withstanding a tape-peeling test (under 48.05 kPa) for around 80 repetitions and sandpaper rubbing (loaded 100 g) for 40 cycles. Furthermore, the coated fabric surface displayed self-healing and oil–water separation capacities. The developed superhydrophobic coatings in this study are robust, environmentally benign, and easy to fabricate, showing promising applications in textile industries.

The polyurethane modified organic silicone (PU-SA) was successfully synthesized via step-by-step polymerization with isophorone diisocyanate (IPDI) and polypropylene glycol (PPG) used as monomers, dibutyltindilaurate (DBTDL) as the catalyst, trimethylolpropane (TMP) and N-methyldiethanolamine (MDEA) as the chain extender, and amino-terminated siloxane (SA) as the blocking agent. The chemical structure of PU-SA was characterized by Fourier transform infrared spectroscopy (FT-IR). X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM) showed that PUSA had been successfully finished on the surface. Additionally, the thermogravimetric analysis (TGA) demonstrated that the PU-SA treated fabrics showed low decomposition temperature and slightly high char residue. As a finishing agent, the effect of PU-SA on the handle of cotton fabrics was also studied by using a Kawabata Evaluation System for Fabrics (KES-F). The experimental results found that PU-SA had a significant improvement on the bending properties, surface properties, and compressional properties. Moreover, the mechanical and anti-wrinkle properties of the cotton fabrics were also enhanced.

A flame-retardant conductive cotton fabric switch was successfully prepared by the in situ polymerization of polyaniline doped with novel phytic acid (PA) by impregnation in an ice water bath for 24 h. The surface morphology, chemical composition, and thermal properties of the fabric before and after the in situ polymerization of polyaniline with PA were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), thermogravimetric analysis (TG), and TG-FTIR. The experimental results demonstrated that the limiting oxygen index (LOI) of the original fabric increased to 32% and the sheet resistance (Rs) decreased to 1.13 kΩ □−1. Under the PA de-doped state, the fabric had no flame-retardant and conductivity properties. Nevertheless, the excellent flame-retardant and conductivity properties of the fabric were obtained once more after re-doping with PA, which indicated that the flame-retardant and conductive textile switch was prepared successfully. Remarkably, the variation in the P content by XPS and the characteristic absorption peak of PA by FTIR made the doping behavior of PA on the surface of different fabrics clear. During the pyrolysis of the original and finished fabric, the maximum decomposition temperature (Tmax) and the maximum emission (Te) of light gas decreased from 380 °C to 290 °C, and the carbon residue content increased from 12.6% to 39.2% at 700 °C, which indicated that the in situ polymerization of aniline doped with PA resulted in the superior flame-retardant property of the fabric. This work provides a green method and basis for the preparation of multi-functional textiles, thus improving the added value of textiles.

Traditional water-based flame-retardant finishing causes serious pollution due to the use of a large number of chemicals, and color change is easily generated since the flame-retardant finishing takes place after the cotton dyeing. An eco-friendly flame-retardant finishing of dyed cotton was explored using 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), 2,2′-oxybis-(5,5-dimethyl-1,3,2,-dioxaphosphorinane-2,2′-disulfide) (5060), SiO2, DOPO/SiO2 (1:1), 5060/SiO2 (1:1) and DOPO/5060 (1:1) in supercritical CO2. The effects of finishing time and pressure as well as temperature on the flame-retarding properties of the cotton were discussed. As expected, samples with the higher weight gain rates exhibit a lower after-flame time as well as after-glow time. In different flame-retardant systems, cotton fabric finished with DOPO presents the lowest after-flame time of 20.6 s and after-glow time of 0 s at 130°C, 22 MPa and 120 min due to its biphenyl ring and O=P-O bond. Moreover, tiny fluctuations of L*, a*, b* and K/S values occurred from 32.10 to 34.24, 5.78 to 6.05, –37.89 to –37.64 and 10.59 to 10.81 when the cotton samples were treated with DOPO, 5060, SiO2, DOPO/SiO2 (1:1), 5060/SiO2 (1:1) and DOPO/5060 (1:1), proving that no significant negative role in the color property of the samples occurs after supercritical CO2 finishing.

There is a continuous demand for a specific type of Chinese silk fabric, which is one of China’s national intangible cultural heritage items called Xiang-Yun-Sha. Xiang-Yun-Sha is silk fabric dyed using the vegetable dyes from a yam and the mud from the Pearl Delta River. The ingenious and sophisticated dyeing process inspires us to explore new dyes for silk. Through learning from the traditional mud dyeing process of Xiang-Yun-Sha, especially the contents of the mud, lignin and iron species are recognized as key factors. Yet little attention has been dedicated to lignin as a dye despite its wide applications. In this study, the feasibility of using lignin to dye silk is investigated using sodium lignosulfonate and alkaline lignin as model systems. Thanks to their advantageous polyphenolic features, such as stacking tendency and ability to form stable complexes with iron ions, lignin-related compounds show excellent performance in serving as dyes by themselves, as well as protective coatings for other dyes; the dyed silk fabric could inherit anti-ultraviolet property from lignin. Considering that iron is inexpensive and that leftover lignin is a vastly underutilized biomass resource, this study offers a promising strategy to exploit the enormous potential of these naturally occurring materials by developing high value-added products.

This research aims to develop a durable and formaldehyde-free flame retardant treatment for cotton fabrics. Phosphorous acid (PA) is employed in conjunction with urea and guanidine carbonate to chemically bond the flame retardant to the cellulose fibers of the fabric. The treated fabrics are evaluated for their flame resistance, comfort, breathability, aesthetics, fire performance, carbon residue, limiting oxygen index, thermal stability, combustion behavior, and fabric properties. The results demonstrate successful grafting of PA onto cotton fabrics, leading to enhanced flame resistance while maintaining the desired fabric characteristics. The treated fabrics exhibit improved fire performance with increased carbon residue from 4.03% to 28.19% and higher LOI values from 18.0% to 43.5%. Moreover, the thermal stability of the fabric is enhanced, resulting in altered combustion behavior characterized by reduced the total heat release from 11.1 kJ/g to 0.1 kJ/g. Importantly, the flame-retardant treatment does not significantly impact the wettability or stiffness of the fabric. This study presents a simple and effective approach to produce highly efficient fire-resistant cotton fabrics, holding promise for various applications where fire safety is a concern.
