Airborne particulate matter (PM) pollution has become a serious threat to human health, thus it is highly desired for a high-filtration-performance and good-wearing-comfort face mask. Herein, a highly breathable and thermal comfort filter medium consisting of electret polyethersulfone/barium titanate nanofibrous membrane (PES/BaTiO 3 NFM) integrated on a nonwoven polypropylene substrate was developed. Benefiting from the high porosity and optimized injection charge energy, the PES/BaTiO 3 membrane was endowed with a good air permeability of 743 mm s −1 , a modest water vapor permeability of 6.24 kg m −2 d −1 , and an enhanced charge storage stability. In addition, the electret PES/BaTiO 3 NFM1.5 medium with a low basis weight of 4.32 g m −2 still shows a high filtration efficiency of 99.99% and a low pressure drop of 67 Pa after being treated at 200 °C for 45 min, which is better than that of commercial media. Moreover, 3D simulation based on the characters of composite membrane was processed to graphically express the airflow distribution during the filtration process. Significantly, the NFM1.5 with a high infrared (IR) transmittance of 93.4% led to an effective radiative cooling to human body radiation. This multifunctional fibrous medium design may provide new insights into the development of environmental adaptive protection materials.

Graphene not only provides functional finishing for fabrics, but also influences the original physical and mechanical properties of the fabrics, reducing their wearing properties. This study conducted graphene conductive finishing on acrylic/wool blended knitted fabrics using an oxidation–reduction method. The research focused on analyzing the reduction of graphene, fabric conductivity, thermal comfort, and hand feel of the fabric, while studying the effects of reduction temperature and time on electrical conductivity, thermal comfort, moisture absorption, breathability, and hand feel during the graphene process. The results revealed that a higher degree of graphene reduction led to lower surface resistance and enhanced electrical conductivity in the acrylic/wool blended knitted fabrics. The stability of the fabric structure and mechanical characteristics were also influenced by temperature and time, impacting comfort attributes. The reduction temperature and duration directly influenced the reduction degree of graphene, with the maximum reduction degree and lowest surface resistance observed at 75 °C and 90 min. Importantly, there was no significant degradation in the thermal comfort and tactility of the acrylic/wool blended knitted fabrics.

Although the bionic evaporative cooling mechanism is regarded as a key path to enhance the thermal management efficiency of the human body outdoors, the structural limitations of traditional fabrics and the bottleneck of heat transfer efficiency led to sweat retention, intensifying the skin’s heat load and restricting the realization of the goal of microenvironment comfort regulation. Here, a metafabric with unidirectional sweat transport and three cooling modes is innovatively fabricated by weaving core–shell yarns via mature weaving techniques. The gradient wetting structure formed in the fabric through the plasma treatment can pull liquid water out of the skin and diffuse it to the outer layer of the fabric for rapid evaporation (0.41 g h −1 ), which is in a leading position in the field of sweat evaporation of cotton materials. Meanwhile, the addition of heat-conducting substances in shell nanofibers has improved the sweat cooling utilization rate of cotton fabrics, providing an additional skin temperature drop of 3.5 ℃ through sweat evaporation. In the outdoor experiment simulating human sweating, a temperature reduction of 7 ℃ is observed for skin-covered metafabric compared with skin-covered cotton fabric. Owing to its exceptional performance, the metafabric can provide promising design guidelines for developing a thermal-moisture comfort textile. Graphical

Driven by escalating concerns over bacterial infections and the global emphasis on public health, the development of multifunctional cotton textiles (CTs) integrating antibacterial, antibacterial adhesion, and self-cleaning properties has garnered significant attention. However, developing durable, antibacterial, and antibacterial adhesion surfaces on CTs without compromising inherent wearing comfort remains a significant challenge. Herein, inspired by long-alkylated quaternary ammonium, chitosan oligosaccharide (COS) and octadecyl amine (ODA) were simultaneously introduced into CTs by utilizing acetoacetyl groups as chemical platforms. The synergistic combination of COS and ODA induces an antibacterial effect analogous to long-alkylated quaternary ammonium by mimicking the structure. Therefore, COS/ODA-CTs achieved stronger antibacterial and antiviral properties (S. aureus: 99.98%, E. coli: 99.78%, and MS2: 98.6%) than CTs finished with COS or ODA alone. Meanwhile, the COS/ODA-CTs exhibit superior antibacterial and antiviral durability. Furthermore, the hydrophobic properties of COS/ODA-CTs conferred self-cleaning and antibacterial adhesion properties, achieving antibacterial adhesion rates against S. aureus and E. coli of 99.97 and 93.28%, respectively. More importantly, the physical properties, including mechanical strength, air permeability, moisture permeability, and hand feeling of the COS/ODA-CTs, were well maintained. These multifunctional CTs provide insights into powerful antibacterial surfaces and show great potential for improving public health and protective clothing applications.

Particulate matter (PM) contamination constituted a significant threat to both human well-being and the worldwide ecological system. However, protective masks achieved high-performance filtration of the PM by tightly stacking fibers, especially for PM 0.1 , which seriously affected the wearing comfort. Herein, a Nylon-6/SiO 2 composite fiber membrane with two-dimension (2D) narrow pore but 3D fluffy structure was designed to harmoniously combine high-performance filtration capabilities with comfort. Based on one-step multi-jet free-surface air-jet spinning and spraying, the introduction of nano-SiO 2 spheres enhanced the surface roughness of the fiber and reduced the pore size of the 2D fiber layer in the membrane structure, improving PM 0.1 particle capture. Additionally, the addition of micro-SiO 2 spheres could construct a fluffy 3D reticular architecture in the membrane, enhancing the flow of air and minimizing gas resistance during the filtration process. Due to the structural design featuring small pores and low packing density, the Nylon-6/SiO 2 -NM membrane exhibited an excellent PM removal rate of 99.99 % and low air resistance of 101 Pa at the flow rate of 32 L/min. At the flow rate of 85 L/min, the filtration efficiency of 99.9 % could be achieved, and the gas resistance was 254 Pa, the performance conformed to the GB 19083-2011. Moreover, the Nylon-6/SiO 2 -NM mask simultaneously possessed superior wearing comfort with air permeability (277.09 mm/s) and moisture permeability (196.50 g·m −2 ·h −1 ) and UV protection (UPF value of 136), as well as good thermal comfort. This research had the potential to introduce a fresh perspective on developing advanced, high-performance, and user-friendly personal protective materials.

As a luxurious textile for more than five thousand years, silk fibers/products have always been favored by consumers and the markets, but the poor photostability seriously hinders its utilization in fashionable apparel. Even if enduing the functionality of silk fiber through surface modification, it is often at the expense of its comfort. Here, an ultra-thin amorphous titanium dioxide nano-film with a thickness of only five in a thousand of fiber diameter and the add-on percentage ≤ 5.33% was prepared on the surface of silk fibers/fabrics by atomic layer deposition (ALD) methods. The tensile strength of the modified silk fiber maintains 89.17% of the original fiber after exposure to UV light for 672 h. They can also withstand multi-cycle laundering and accelerate light-aging, which exhibiting an excellent UV resistance. Most importantly, the functional coating has a negligible impact on the comfortable and wearability performance of silk fibers/fabrics. In addition, ALD-coated silk fabric is also further used as an outdoor reflective cooling material and achieving a superior thermal insulation effect with the temperature reduction up to 10.1 °C.

Polyurethane (PU) can be synthesized by replacing petrochemical polyols partially with lignin, thus improving the environmental benefit and the comprehensive performance of the foam. Herein, sulfomethylated Kraft lignin (SKL) is obtained by sulfonation of Kraft lignin (KL), and then it is used as filler to synthesize the sulfomethylated lignin-based flexible polyurethane foam (SLFPUF). The effects of SKL with different sulfonations on SLFPUF are explored. Thermogravimetric (TG) analysis shows that when the sulfonation is 0.286 mmol/g, the residual mass is 12.63 % that is higher (3.35 %) compared to the control group lignin-based flexible polyurethane foam (LFPUF), indicating better thermal stability. The support factor (SF) of SLFPUF-0.286 is 4.99, higher than that of LFPUF (1.89), showing good softness. The air flow of SLFPUF-0.286 is 756.9 Pa, lower than that of LFPUF (996.8 Pa), demonstrating good comfort. Moreover, the resiliency of SLFPUF-0.286 is 9.67 %, exhibiting a shape memory property, which has potential applications in the production of functional products with low resilience.

The human body's thermoregulation is intrinsically linked to thermal-moisture transfer. Wearable textile-based humidity actuators that adapt to human body microenvironments represent a promising approach for dynamic personal thermal management, an area that remains underexplored. Here, we present an all-fibrous sandwich-structured humidity actuator with multimodal thermal management capabilities. This actuator consists of uniaxially aligned hydrophilic polyvinyl al co hol nanofibers, hydrophobic poly(vinylidene fluoride-co-hexafluoropropylene) nanofibers, and silver nanowire (AgNW) layers. The asymmetric hygroscopicity and aligned nanofibers enable regular and large bending deformation that reversibly responds to humidity changes. Significantly, a warming mode maintaining 31.2 °C is operated when the actuator remains in a closed flat state under dry, cold conditions, with the low-emissivity AgNWs and all-fibrous architecture effectively suppressing heat dissipation; while skin perspiration-triggered opening under hot conditions activates a cooling mode maintaining 28.7 °C, permitting direct thermal convection, radiation, and moisture evaporation. Additionally, the electrically conductive AgNWs introduce an active heating mode for extremely cold conditions, enabling the actuator to readily achieve 37 °C at just 0.3 V. Wearable experiments demonstrate the actuator's practical applicability and effective comfort management. This all-fibrous, multi-dynamic humidity actuator provides a viable pathway toward energy-efficient smart textiles for personal thermal management across various environments.

Directional water transport in garment materials plays a pivotal role in maintaining human thermal and wet comfort. In the present work, a new type of multilayer fibrous mat with the specific function of directional water transport was prepared via the combination of melt-electrospinning and solution-electrospinning. The polypropylene (PP) fibrous layer prepared by melt-electrospinning technology was located in the inner layer (next to the skin), while the polyacrylonitrile-containing hydrophilic nano-silica particles (PAN-SiO2) layer with remarkable hydrophilicity was located in the outer layer, which could effectively transport water to the outer surface of the composites. Treatment of the as-prepared PAN-SiO2/PP with an alkaline aqueous solution of dopamine not only increased the wettability of the PP layer, but also further improved the hydrophilicity of PAN-SiO2. A layer of cotton woven mesh was added between the TPP layer and TPAN-SiO2 to form a sandwich structure in order to accelerate water transport in the bilayered fibrous mats. The directional water transport, mechanical flexibility, and permeability of the prepared multilayered superfine fibrous mat were characterized systematically. The experimental results exhibited that TPAN-SiO2/cotton mesh/TPP exhibited an excellent accumulative one-way transport index (AOTI, 1071%), remarkable overall moisture management capacity (OMMC, 0.88), and reasonably high water vapor transport rate (WVT, 11.6 kg d−1 m−2), indicating it is a promising candidate for the development of novel textile materials for use in the field of sportswear for fast sweat release applications.

As the aging population increases in many countries, electronic skin (e-skin) for health monitoring has been attracting much attention. However, to realize the industrialization of e-skin, two factors must be optimized. The first is to achieve high comfort, which can significantly improve the user experience. The second is to make the e-skin intelligent, so it can detect and analyze physiological signals at the same time. In this article, intelligent and multifunctional e-skin consisting of laser-scribed graphene and polyurethane (PU) nanomesh is realized with high comfort. The e-skin can be used as a strain sensor with large measurement range (>60%), good sensitivity (GF≈40), high linearity range (60%), and excellent stability (>1000 cycles). By analyzing the morphology of e-skin, a parallel networks model is proposed to express the mechanism of the strain sensor. In addition, laser scribing is also applied to etch the insulating PU, which greatly decreases the impedance in detecting electrophysiology signals. Finally, the e-skin is applied to monitor the electrocardiogram, electroencephalogram (EEG), and electrooculogram signals. A time- and frequency-domain concatenated convolution neural network is built to analyze the EEG signal detected using the e-skin on the forehead and classify the attention level of testers.

Personal thermal management (PTM) significantly enhances human thermal comfort by alleviating overheating-induced stress. However, achieving energy-free cooling, intelligent temperature regulation, lightweight construction, and wearable designs remains challenging. This study introduces a coaxial electrospinning nanofiber membrane with a core-sheath structure using polyvinyl alcohol as the matrix, phase change microcapsules (PCMC) for energy storage, and nano-silica (SiO 2 -NPs) for radiative cooling. The resultant membrane effectively provides cooling without external energy input. The PVA/SiO 2 -30 shell exhibits high solar reflectance (80%) and mid-to-long infrared emissivity (95%), while the PCMC-loaded core prevents leakage during phase transitions, achieving a melting enthalpy of 79.7 J·g − . Under simulated solar radiation, the membrane maintains an equilibrium temperature ≈14.2 °C lower than conventional cotton fabric, demonstrating superior thermal stability. Moreover, the membrane exhibits excellent mechanical performance, with tensile strength of 2.71 MPa, elongation at break of 128%, and lightweight properties (3.125 gm −2 ). The one-step coaxial electrospinning process simplifies fabrication, enhancing interlayer adhesion and enabling efficient multifunctional textile production. This approach offers significant potential for developing intelligent, lightweight, and energy-efficient wearable cooling textiles.

A multi-use fibrous filter medium composed of an electrospun polyimide (PI) nanofiber layer and a functional zeolitic imidazolate framework-8 (ZIF8) nanofilm layer was successfully fabricated to cope with the complex environmental pollution issues. The nanofilm layer consists of the anti-microbial ZIF8 converted from non-toxic zinc oxide (ZnO) nanocoating on PI fibers. One-step magnetron sputtering is utilized to deposit the ZnO nanocoating for the sake of desired functionality conformally onto the PI nanofibrous membrane without sacrificing its bulk structure and mechanical performance. The as-prepared PI/ZIF8 nanofibrous filter medium showed conspicuous biocidal efficacy and excellent interception ratio against gram-negative Escherichia coli (>99.9%) and gram-positive Staphylococcus aureus (>99.9%) within 20 min contact. Besides, compared with commercial media, the bilayer PI/ZIF8 fibrous medium showed exceptional thermal-wet comfortability due to the high porosity that could realize effective heat and humidity conduction. Moreover, the PI/ZIF8 30 NFM still present a high filtration efficiency of 99.6% towards PM 0.3 even after treated at 300 °C for 1 h. Furthermore, the PI/ZIF8 30 NFM with a fiber basis weight of 1.8 g/m 2 was endowed with a permeate flux of 17,279.2 L/m 2 /h and a high oil/water separation efficiency of > 99.6% because of the hydrophobicity and superoleophilicity. We envision that the antimicrobial, thermal-wet comfort, multi-use fibrous membrane will serve as a core-medium of environmentally-friendly platform for bioprotective equipment against future pathogen threats or oily wastewater treatment .
