Cotton is the seed fiber of the Gossypium plant (from the Malvaceae family), which is one of the most important crops worldwide and is suitable for the application in clothes, furniture, and industrial fabrics areas. Combustible cotton easily triggers fire hazard. Thus, a phosphorous˗nitrogen flame retardant, ammonium salt of tris˗(hydroxymethyl)˗aminomethane˗penta(methylphosphonic acid) (ATPMPA) was synthesized to produce fire˗retardant cotton. The ATPMPA structure was characterized by nuclear magnetic resonance ( 1 H NMR, 13 C NMR, and 31 P NMR) spectroscopy. ATPMPA flame˗retardant cotton was prepared by phosphate esterification between ATPMPA and the ˗OH groups of cotton cellulose. Scanning electron microscopy verified that the surface of the treated cotton fiber was not obviously changed. The flame retardantcy of cotton was tested using the LOI, vertical burning and cone calorimetry. The results revealed that the LOIs of the control cotton and treated cotton fabrics increased from 18.4% to 40.8%, 42.4%, and 43.6% after treated with 20 wt%, 30 wt% and 40 wt% flame retardant, respectively. After 50 laundering cycles (LCs), the LOIs of the treated cotton fabrics only decreased to 26.7%, 30.8%, and 32.3%, respectively, indicating that treated cottons obtained the superior flame retardancy and excellent washing resistance. Thermogravimetry (TG) analysis showed that the charring ability of the treated cotton was markedly improved. TG-IR result of treated cotton indicated that the decomposition temperature and the amount of volatile matter produced by the flame-retardant cotton were lower than that of control cotton. The whiteness of treated cotton sustains well.

Layer-by-Layer (LbL) assembly was attractive as a versatile tool to address the flammability of cotton, while the washing fastness of LbL coating stayed an issue. Aiming to tackle this issue, LbL layers consisted of phenylphosphonic acid (PHA) and 3-aminopropyltriethoxysilane (APTES) was deposited on polydopamine (PDA)-coated cotton. The prepared cotton reached 31.4% of limiting oxygen index (LOI), and extinguished immediately after removing the ignitor. Peak of heat release rate (pHRR) attenuated around 36 % compared with pure cotton. A combined barrier and quenching mechanisms were proposed. Moreover, enhanced washing durability (24.1% of LOI) was achieved even after 50 detergent laundering cycles. A facile, boosted LbL approach with proposed π − π stacking interactions between PDA abundant aromatic structures and benzene ring in PHA from LbL layers, is first to put forward to construct durable efficient flame retardant (FR) cotton. This work attempted to enlighten more thoughts and design for durable FR cotton fabrics.

A novel poly(4-iodobutoxylmethylsiloxane) (PIBMS) water repellent with high reaction activity was synthesized using poly(hydromethylsiloxane) (PHMS), methyl iodide (MeI) and tetrahydrofuran (THF) in the presence of a catalytic amount of PdCl2. The new chemical active group of PIBMS could covalently bond to the cotton fabric. It is conducive to improve the washability of treated cotton fabric. The structure of PIBMS was confirmed by the FT-IR and 1H NMR spectra. The PIBMS was applied onto cotton fabric by a pad-dry-cure process. PIBMS was applied to cotton fabrics and the effect of the process parameters on water repellent performance was studied. The morphology of PIBMS polymer film on the cotton fabric was investigated by SEM. The water repellency of treated cotton fabrics before and after vigorous washes was compared. The results show that the water repellent grade of cotton fabric treated with PIBMS was 90. The contact angle of the treated cotton fabric was 136.94°, which was higher than that of the untreated cotton fabric. The water repellent grade of treated cotton fabric was still as high as 80 after 20 times washing. The tear strength and the tensile strength of cotton fabric significantly increased after PIBMS treatment. The air permeability and the water vapor permeability of treated cotton fabric were slightly lower than those of untreated cotton fabrics.

In this article, amino-functionalized TiO2 (TiO2/KH550) was obtained via a mild reaction between 3-aminopropyltriethoxysilane and TiO2 with the aid of concentrated ammonia solution. 4-((4,6-Dichloro-1,3,5-triazine-2-yl)amino) sodium benzenesulfonate (SAT) was synthesized and characterized using 1H NMR and Fourier transform infrared spectroscopy (FT-IR). Self-dispersive and reactive TiO2 (TiO2/KH550/SAT) was prepared via a nucleophile substitution reaction between TiO2/KH550 and SAT. Finally, cotton fabric samples loaded with different amounts of TiO2/KH550/SAT were achieved via an exhaust dyeing method. The chemical structures, dispersions, and thermal performances of TiO2, TiO2/KH550, and TiO2/KH550/SAT were investigated using FT-IR, zeta potential measurements, and thermogravimetric analysis (TG). The crystalline phase, morphology, chemical composition, and optical absorption properties of the cotton fabrics were studied using X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS). Moreover, the anti-ultraviolet, self-cleaning, and washing fastness properties of the cotton fabrics were investigated. It was found that TiO2/KH550/SAT demonstrated excellent dispersion stability in aqueous solution, even after standing for a month. Cotton fabrics loaded with TiO2/KH550/SAT exhibited attractive anti-ultraviolet performance, highly efficient and durable self-cleaning activity, and appreciable washing fastness. A mechanism and possible reactions related to the preparation of the self-cleaning cotton fabrics loaded with TiO2/KH550/SAT were proposed.

Superhydrophobic fabrics suffer from being commonly penetrated by moisture after laundering, seriously deteriorating their water repellency after air drying. Numerous researchers have successfully recovered superhydrophobicity by drying in fluid ovens; however, high energy consumption and equipment dependence limit practical applications. Herein, the superhydrophobic photothermal self-healing cotton fabric (SPS cotton fabric) was fabricated by depositing a composite layer of cellulose nanocrystal-MXene (C-MXene) and polyacrylate (PA) coatings on the cotton cloth. Superior photothermal conversion of the SPS cotton fabric performance enables its 10.5–56.8 °C greater temperature than that of the pure hydrophobic cotton fabric under different simulated solar light intensities. After washing, the SPS cotton fabric can spontaneously restore superhydrophobicity with ≈100% efficiency by 30 mW·cm–2 solar light irradiation; in contrast, the single superhydrophobic fabrics recover only ≈71.2%. Even after 10 washing cycles, the recovery efficiency of the SPS cotton fabric only decreases by 0.1%, exhibiting excellent laundering durability. The SPS cotton fabric can retain ultralong time antifrosting (2760 s) and antifreezing (4080 s) capacities due to sustainable water repellency. Remarkably, the excellent self-healing capability of the SPS cotton fabric is attributed to the fact that the coiled nonpolar alkane chains can be restored to a straight state by autothermal drive, confirmed through element analyses and molecular dynamics simulations.

Conductive fabric combines many advantages of fabric including durability, flexibility, and comfort, and has broad prospects in the field of wearable electronics. A multilayer silver deposition fabric with ultrahigh washability is prepared by combining 3 -mercaptopropytrimethoxysilane (MPTS) and N -acetyl- L -cysteine (NAC) in the fabrication process. Silver particles were deposited on polyester fabric (PETF) by electroless plating with glucose as a reducing agent. MPTS is grafted on PETF by condensation reaction to ensure that the first layer of silver is firmly deposited on the fabric. NAC with sulfhydryl and carboxyl groups is used as the binder between the next silver layers. NAC treatment of silver-plated fabric can not only eliminate the loosely attached silver particles on the fabric, but also increase the adhesion between the silver layers by sulfhydryl and carboxyl groups. The electrical resistance of the two-layer silver plated fabric (Ag 2 /M-PETF) is as low as 0.016 Ω sq −1 , which is only 2.06 Ω sq −1 after 500 washing cycles and 0.068 Ω sq −1 after 1000 friction cycles. Ag 2 /M-PETF also shows good hydrophobicity , mechanical properties and thermal stability.

The worldwide outbreak of SARS-CoV-2 has attracted extensive attention to antibacterial and antivirus materials. Cellulose is the most potential candidate for the preparation of green, environmentally friendly antibacterial and antiviral materials. Herein, modified cellulosic fibers with sustained antibacterial and antiviral performance was prepared by introducing chitosan oligosaccharide onto the fibers. The two-step method is proved to be more effective than the one-step method for enhanced chitosan oligosaccharide loadings and antibacterial and antiviral activity. In this instance, the modified fibers with 61.77 mg/g chitosan oligosaccharide loadings can inhibit Staphylococcus aureus and Escherichia coli by 100 % after contacting with bacteria for 12 h and reduce the bacteriophage MS2 by 99.19 % after 1 h of contact. More importantly, the modified fibers have washing durable antibacterial and antiviral activity; the modified fibers have 100 % antibacterial and 98.38 % antiviral activity after 20 washing cycles. Benefiting from the excellent performance of the individual fibers, the paper prepared from the modified fibers show great antibacterial (100 %) and antiviral performance (99.01 %) and comparable mechanical strength. The modified fibers have potential applications in the manufacture of protective clothing and protective hygiene products.

This article focuses on the functional finishing of textiles using silver nanoparticles (AgNPs) and chitosan derivative binder, which was synthesized by a modification of chitosan using α-ketoglutaric acid. The binder covalently linked to cotton fabric via esterification of the hydroxyl groups on the cotton surface, and tightly adhered to surface of the AgNPs by coordination bonds. As a result, the coating of AgNPs on the cotton fabric showed excellent antibacterial property and laundering durability. After 30 consecutive laundering cycles, the Ag content on the fabrics decreased to 37.6 %, but the bacterial reduction rates against both S. aureus and E. coli were maintained over 95 %. It has potential applications in a wide variety of fields such as sportswear, socks, and medical textile.

The conventional antimicrobial treatment process for cellulose based fabrics such as cotton fabrics faces significant challenges, including suboptimal durability of antimicrobial coatings and degraded mechanical properties of textiles after treatment. Herein, an antimicrobial adhesive of silver and copper composite nanoparticles (AgCuNPs) was prepared by simultaneous in-situ reduction of Ag + and Cu 2+ in the presence of waterborne polyurethane (WPU). The synthesized AgCuNP glue exhibited an average particle size as low as 2.1 nm, a zeta potential as high as −64.8 mV at the optimum mass ratio of WPU to AgCu of 9:1, and high adhesion strength to cellulose, which ensured good wash resistance of AgCuNPs. WPU was found to form a closed film on the surface of cotton fibers, thereby providing AgCuNPs with adequate adhesion strength. In addition, AgCuNP-coated cotton fabric as low as 100 mg/kg showed ~100 % antibacterial rates against Escherichia coli and Staphylococcus aureus after 50 washes, indicating excellent washability. Finally, the 100 mg/kg of coated cotton fabric showed good resistance to abrasion and sunlight exposure, good biocompatibility, and enhanced mechanical properties. The tensile strength and hydrophobicity of AgCuNP-coated cotton fabric were improved after treatment, probably because the penetration of WPU into the yarn improved fiber cohesion.

Fiber-based flexible thermoelectric (TE) materials are very promising for wearable electronics . Carbon nanotubes (CNTs) have shown considerable promise as thermoelectric materials , however, integrating CNTs into a fiber always lowers the performance, which limits the application of CNT-based fibers (CNTFs). This work proposes a low-cost and simple manufacturing process based on electrostatic spray technique to prepare high-performance CNTFs, whose TE and mechanical properties can be optimized by tuning spray voltage and time. With the aid of the optimized electrostatic field , the prepared CNTFs possess excellent durability and the electrical conductivity showing almost no degradation after being washed and deformed repeatedly. In addition, the CNTFs are proved to be easily converted into n-type via polyethyleneimine (PEI) doping process. Based on the prepared p- and n-type CNTFs, this work fabricates a π-type thermoelectric generator (TEG), of which the CNTFs show the ability to optimize thermal design to compensate negative effect of the intrinsic high thermal conductivity of CNTs on the output performance of the device. As a result, a maximum power of 26.2 nW with output voltage of 6.46 mV is achieved at a temperature difference of 33.4 K. This method provides a new way for preparing high-performance fiber-based TE materials.

The chitosan (CS)/cellulose nanocrystal (CNC) (0, 0.2. 0.5, 0.8 and 1 wt%) nanocomposites were applied as modifier, and then deposited on the surface of cotton fabric via a pad-dry-cure method. The morphology, mechanical, hydrophilicity and ultraviolet (UV)-blocking properties of prepared fabrics were carefully investigated. The results showed that CS/CNC could obviously enhance the UV-blocking property of cotton fabric. CS/CNC0.5 fabric exhibited the most excellent UV-blocking property as well as good washing durability after 30 times water laundering, indicating CS/CNC could be used as efficient and durable UV blocker for cotton fabric. In addition, CS/CNC also can increase the mechanical property of cotton fabric; while decrease the hydrophilicity of cotton fabric.

In this work, we developed a new method that can achieve immobilization and protection of the Cu NPs coating on the cotton fabrics by a simple two-step impregnation method. Firstly, L-cysteine (Cys) was grafted onto cotton fabric via esterification with the hydroxyl groups of cellulose, then Cu NPs were introduced on the fabric surface in the presence of a protective reagent, citric acid. Due to the doubled stabilization acts of Cys and citric acid, the Cu NPs immobilized on the fabric surface showed an excellent antibacterial effect and outstanding laundering durability. As a result, the mean size of the Cu NPs coating on the cotton fabric is about 62.4 nm, and the modified cotton fabrics showed satisfactory antibacterial ability against both S. aureus and E. coli , which the bacterial reduction rates are all higher than 98 % even withstand 50 washing cycles. Therefore, this method to prepare antibacterial cotton fabrics showed great potential applications in socks, cosmetic, and medical textiles.
