Microbial dyes have received substantial attention because of their natural environmental protection, simple access, and reduced regional and seasonal restriction. In this work, a microbial dye, the yellow pigment produced by Metarhizium anisopliae , was first studied then applied. The strain produced by the culture was identified, and the conditions for producing yellow pigment were optimised. Further, the stability of M. anisopliae yellow pigment was examined, and the pigment was applied to the dyeing of silk and wool fabrics. The results showed that the homology of the strain with M. anisopliae was 99.98%. In liquid fermentation culture, the optimal carbon source was glucose, and the dosage was 30 g/l. The maximum pigment yield can be obtained by culturing with 4% v/v of inoculation quantity at pH 7 and 30 °C. In addition, the effects of pH, temperature and metal ions on the yellow pigment of M. anisopliae were significant. The optimum dyeing process conditions were dyeing temperatures of 80 °C for silk and 90 °C for wool, with a dyeing time of 60 min. This research developed a novel microbial dye and studied its application for the dyeing of protein fibres.

In recent years, textiles with antimicrobial properties have attracted more and more attention. As natural antimicrobial agents, essential oils’ potential application value lies in their ability to provide textiles with antimicrobial functions. In this paper, organic solvent extraction (n-hexane, petroleum ether, ethanol) and steam distillation were used to extract saffron petal essential oil (SPEO). It was found that organic solvent extraction (ethanol) had the highest extraction rate and the most apparent bacteriostatic effect. SPEO-Ms were prepared using the composite condensation method with gelatin and chitosan. The microstructure, encapsulation efficiency, slow-release performance, infrared spectrum, and thermal stability of the SPEO-Ms were evaluated. The results showed that the microencapsulated essential oil had good bacteriostatic properties. Antimicrobial cotton fabric was prepared by impregnating microcapsules onto cotton fibers. The effects of the microcapsules’ concentration on the whiteness, air permeability, moisture permeability, and bacteriological inhibition of the fabric were investigated. The results revealed that SPEO-Ms have the potential to be used as a new antimicrobial agent in textiles.Keywords:saffron flower petal essential oil;microcapsule;antimicrobial cotton fabric;cotton fabric

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.

Harvesting energy directly from the body heat has been suggested as an effective way to realize sustainably and uninterruptedly wearable power supply. However, the low temperature gradient (ΔT) between the human body and the environment has limited the power generation efficiency. In this study, the photothermal-thermoelectric 3D spacer fabric (ZrC-PPSF) was prepared by coating a thin zirconium carbide/polyurethane (ZrC/PU) photo-thermal layer on the poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS)/spacer fabric (SF) thermoelectric composite (PPSF). By utilizing the excellent photo-thermal conversion of ZrC and the thermal insulation performance of PPSF, a larger ΔT was generated and maintained, so as to enhance the power generated and efficiency. The effects of ZrC concentration, SF thickness and optical power density on the photo-thermal efficiency and voltage generated were studied. When the ZrC concentraiton is 1.5 wt%, the ΔT increases form 67.5 °C to 179.3 °C under the optical power density of 500 mW/cm 2 . Regardless of sunny and cloudy day, a larger ΔT can be generated. Based on this, a flexible and wearable wristband containing 30 ZrC-PPSF units was prepared. Encouragingly, the voltage generated by the wristband under the sunshine is almost 11 times the voltage generated indoors. Under the optical density of 100 mW/cm 2 for 800 min, the highest voltage generated by the wristband is 9.11 mV, much higher than the 3.12 mV generated without light. All the results demonstrate that it is a very effective and simple method to improve the thermoelectric power generation efficiency by photo-thermal conversion. The wearable TE device prepared in this study is especially suitable for outdoor application, and provide continuous and stable energy for the wearable electronics.

Thanks to the booming development of wearable electronics, finding a facile approach to integrate electronics to textiles becomes attractive. However, many disadvantages such as trivial fabrication steps, limitations of textile substrate types and unavoidable damage to textiles’ natural properties, have hampered the development of wearable electronics. In this work, pressure responsive PET fabrics were produced through a facile fabrication of conductive PET fabrics. Firstly, fine conductive adhesives (CA) with good printing performance were prepared by utilizing alcohols-assisted dispersion to prevent Ag NPs’ aggregation tendency in waterborne polyurethane (WPU). Then, screen printing on PET fabrics and subsequently treated with solvent system that consisted diallyldimethylammonium chloride (DADMAC), dichloromethane (DCM) and ethanol to construct conductive wrinkles at room temperature. With the help of WPU’s swelling, the conductive path was generated by Ag NPs spontaneous aggregation and the as-prepared conductive PET fabrics demonstrated outstanding electric conductivity (0.01 Ω·m). Finally a simple self-assembly PET fabrics pressure sensor based on the conductive PET fabrics exhibited superior performance, including the synchronous response to thumb pressing (frequency was 0.5 Hz), precisely distinction current of different weights, decent bending stability, fast response (63 ms) and relaxation time (23 ms), simultaneously possessing advantages of low cost and facile fabrication process. Based on its superior performance, the PET fabric sensor was developed to monitor the human fist behavior at different frequency (0.25 Hz and 1 Hz) and its good real-time response current, meeting the potential application requirements in wearable electronics and “smart textiles” for monitoring human’s movement behavior.

In the last several decades, electronic ink (e-ink) microcapsules have been extensively employed in display screens owing to their high reflectivity and contrast under visible light irradiation, as well as their flexibility, low cost, and low power consumption. Herein, a simple coating technique serves to combine e-ink microcapsules containing multiple color particles with fabrics to design an intelligent reversible electrochromic flexible electronic fabric. E-ink microcapsules, transparent Ag nanowires (T-AgNWs), and single-walled carbon nanotubes (SWCNT) are sequentially and uniformly coated on the surface of the double-layer conductive strip structure composed of conductive fabric and insulating fabric. The electrophoretic discoloration of the e-ink microcapsules can be achieved by applying voltages of a certain magnitude between the bottom conductive fabric strip layer and the T-AgNWs/SWCNT composite conductive layer. Large-area flexible electrochromic fabrics can be formed by weaving strips coated with e-ink microcapsules materials based on the results of the continuous bending and soaking experiments, which has great application potential in the research of adaptive camouflage smart fabrics in the visible light field.

Carbonized cotton fabric possesses lightweight softness, stable chemical structure and can be used as wearable electronic skin. However, conventional carbonization method relies on high temperature, oxygen-free or inert gas atmosphere with long time consumption. In this study, a hybrid intumescent flame retardant (IFR) coating was introduced on the surface of cotton fabric. When they were placed directly into the heated muffle furnace at air atmosphere, the IFR coating would quickly react with the cotton fiber to form char residue and release non-inflammable gases, providing an inert atmosphere microenvironment for the pyrolysis and carbonization of cotton fabric substrate. The influence factors of temperature and carbonization time were studied comprehensively. Especially, carbonizing for only 15 min at 900 °C shows a value of 26.33 dB. Besides, such fabrics perform the ability for photo-thermal conversion and fire resistance performance. This simple and feasible carbonization strategy holds great promise for large-scale production of flexible conductive fabrics.

The trends of wearable health monitoring systems have led to growing demands for gait-capturing devices. However, comfortability and durability under repeated stress are still challenging to achieve in existing sensor-enabled footwear. Herein, a flexible textile piezoresistive sensor (TPRS) consisting of a reduced graphene oxide (rGO)-cotton) fabric electrode and an Ag fabric circuit electrode is proposed. Based on the mechanical and electrical properties of the two fabric electrodes, the TPRS exhibits superior sensing performance, with a high sensitivity of 3.96 kPa-1 in the lower pressure range of 0–36 kPa, wide force range (0–100 kPa), fast response time (170 ms), remarkable durability stability (1000 cycles) and detection ability in different pressures ranges. For the prac-tical application of capturing plantar pressure, six TPRSs were mounted on a flexible printed circuit board and integrated into an insole. The dynamic plantar pressure distribution during walking was derived in the form of pressure maps. The proposed fully-textile piezoresistive sensor is a strong candidate for next-generation plantar pressure wearable monitoring devices.Keywords:textile piezoresistive sensor (TPRS);rGO-cotton fabric electrode;Ag fabric circuit electrode;insole;dynamic plantar pressure

Pressure therapy combined with silicone has a significant effect on scar hyperplasia, but limitations such as long-term wearing of compression garments (CGs) can easily cause bacterial infection, cleanliness, and lifespan problems of CGs caused by the tedious operation of applying silicone. In this study, a compression garment fabric (CGF) with both inhibition of scar hyperplasia and antibacterial function was prepared. A polydimethylsiloxane (PDMS)-loaded microcapsule (PDMS-M) was prepared with chitosan quaternary ammonium salt (HACC) and sodium alginate (SA) as wall materials and PDMS as core materials by the complex coagulation method. The PDMS-Ms were finished on CGF and modified with (3-aminopropyl)triethoxysilane (APTES) to obtain PDMS-M CGF, which was further treated with HACC to produce PDMS-M-HACC CGF. X-ray Photoelectron Spectroscopy(XPS) and Fourier transform infrared spectroscopy (FTIR) analysis confirmed the formation of covalent bonding between PDMS-M and CGF. The PDMS-M CGF exhibited antibacterial rates of 94.2% against Gram-negative bacteriaEscherichia coli(E. coli, AATCC 6538) and of 83.1% against Gram-positive bacteriaStaphylococcus aureus(S. aureus, AATCC 25922). The antibacterial rate of PDMS-M-HACC CGF against bothE. coliandS. aureusreached 99.9%, with wash durability reaching grade AA forE. coliand approaching grade A forS. aureus. The finished CGF maintained good biocompatibility and showed minimal reduction in moisture permeability compared to unfinished CGF, though with decreased elastic recovery, air permeability and softness. The finished CGF of this study is expected to improve the therapeutic effect of hypertrophic scars and improve the quality of life of patients with hypertrophic scars.

Flexible electronic devices have attracted considerable attention in recent years. Textile fabrics have been widely used to fabricate flexible strain sensors owing to their high flexibility. However, the elasticity of ordinary textile fabrics is low, which limits their strain sensing range. In this article, we used a simple method to fabricate flexible strain sensing fabrics (FSSFs) through the coating of graphene oxide (GO) nanosheets on elastic nylon/polyurethane (nylon/PU) fabric, followed by reduction of GO with sodium borohydride . The reduced graphene oxide (RGO) nanosheets were adsorbed on the elastic fabrics to impart electrical conductivity to the fabrics. The coated fabrics were characterized with scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Raman scattering spectroscopy. The electromechanical performance and strain sensing properties of the FSSF were investigated. The fabricated strain sensor exhibited high sensitivity, a large workable strain range (0–30%), fast response and great stability. The mechanical property of fabrics did not change remarkably after the treatment with RGO. The surface resistance of the RGO/nylon/PU only increased from ∼112 KΩ/m 2 to ∼154 KΩ/m 2 after 8 washing cycles, exhibiting good washability . Furthermore, real-time monitoring of human motions, such as bending of finger and rotation of wrist, was achieved by the as-prepared FSSF. The RGO/nylon/PU fabrics as flexible strain sensors have potential applications in wearable electronic devices.

The development of wearable electronics, energy storage, and smart sensing has significantly increased the demand for highly conductive circuits on textiles. Silver (Ag) is a preferred material due to its excellent electrical conductivity, antibacterial properties, and biocompatibility. However, the hydrophobic nature and low surface energy of polyethylene terephthalate (PET) fabrics pose challenges for the adhesion of silver particles, limiting the mechanical durability and washability of conductive layers. This study proposes a novel strategy combining the synergetic pretreatment of PET fabrics using reducing agents (ascorbic acid and glucose) and hydroxypropyl methylcellulose (HPMC) to enhance the deposition of silver layers. The reducing agents facilitate the conversion of silver ions to metallic silver, while HPMC forms a uniform film on the fabric surface, providing anchoring points for silver particles through hydrogen bonding. The resulting silver layers exhibit high conductivity, uniformity, and durability, as confirmed by SEM, XRD, and XPS analyses. The treated fabrics demonstrate low electrical resistance and excellent abrasion resistance after multiple washes and rubbing. This method offers a simple, scalable, and cost-effective approach for constructing conductive textiles, with potential applications in wearable electronics and smart sensing.

The electrically conductive and flame-retardant bifunctional cotton fabrics were fabricated by polymerizing pyrrole (Py) onto the cotton fabrics and followed by doping phytic acid (PA) via a chemical oxidation method. The prepared cotton fabrics were then characterized by Four-point Probes Resistivity Measurement, Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Fourier Transform Infrared Spectroscopy (FTIR), Vertical Burning Test and Thermogravimetric Analysis (TGA). The results of SEM and FTIR tests indicated that pyrrole was successfully polymerized on the cotton fabrics. The EDS measurements showed that the phosphorus increased with increasing phytic acid concentration. The results of four-point probes resistivity measurement, vertical burning test and TGA test exhibited that both the electrical conductivity and the Limit Oxygen Index (LOI) of the treated fabrics increase with increasing phytic acid concentration. The LOI of the cotton fabric increased from 18% to 37.6% after the cotton fabric was deposited with polypyrrole and doped with phytic acid. The conductivity of the treated cotton fabrics is mainly affected by the pyrrole concentration and can reach about 0.28 S cm −1 .
