Working conditions for fire fighters can be described according to the environment temperature and incident radiant heat flux. Measurements this study in buildings fighting training have shown that are typically exposed fluxes of between 5 10 kWm(-2) during kind exercise. The load nevertheless much higher. In one case, 42 was measured. temperatures reached 100 190 degrees C at 1 m above ground, going up 278 case. Human trials been performed with 17 fighters. After exercises (about 15 min) a...

Electronic and photonic fiber devices that can sustain large elastic deformation are becoming key components in a variety of fields ranging from healthcare to robotics wearable devices. The fabrication highly functional fibers remains however challenging, which is limiting their technological developments. Simple scalable fiber-processing techniques continuously codraw different materials within polymeric structure constitute an ideal platform realize Despite decades research however,...

Calculation of evaporative heat loss is essential to balance calculations. Despite recognition that the value for latent evaporation, used in these calculations, may not always reflect real cooling benefit body, only limited quantitative data on this available, which has found little use recent literature. In experiment a thermal manikin, (MTNW, Seattle, WA) was determine effective power moisture evaporation. The manikin measures both and mass independently, allowing direct calculation an...

In this paper, a textile-based respiratory sensing system is presented. Highly flexible polymeric optical fibres (POFs) that react to applied pressure were integrated into carrier fabric form wearable system. After the evaluation of different fibres, setups compared. To demonstrate feasibility such sensor, setup featuring best performance was placed on human torso, and thus it possible measure rate. Furthermore, we show enables keep track way breathing (diaphragmatic, upper costal mixed)...

For the long-time monitoring of electrocardiograms, electrodes must be skin-friendly and non-irritating, but in addition they deliver leads without artifacts even if skin is dry body moving. Today’s adhesive conducting gel are not suitable for such applications. We have developed an embroidered textile electrode from polyethylene terephthalate yarn which plasma-coated with silver electrical conductivity ultra-thin titanium layer on top passivation. Two these embedded into a breast belt. They...

Electrospun nanofibrous membranes offer superior properties over other polymeric not only due to their high membrane porosity but also surface-to-volume ratio. A plethora of available polymers and post-modification methods allow the incorporation "smart" responsiveness in fiber membranes. The pH-responsive property is achieved using from class polyelectrolytes, which contain pH-dependent functional groups on backbone. Electrospinning macroscopic polyelectrolytes earned considerable interest...

Electrospun nanofibers have shown great potential as drug vehicles and tissue engineering scaffolds. However, the successful encapsulation of multiple hydrophilic/hydrophobic therapeutic compounds is still challenging. Herein, sodium alginate/poly(ε-caprolactone) core/shell were fabricated via water-in-oil emulsion electrospinning. The alginate concentration, water-to-oil ratio, surfactant concentration optimized for maximum stability emulsion. results demonstrated that an increasing ratio...

Abstract Reusable face masks are an important alternative for minimizing costs of disposable and surgical during pandemics. Often complementary to washing, a prolonged lifetime relies on the incorporation self-cleaning materials. The development mask materials requires presence durable catalyst deactivate contaminants microbes after long-term use without reducing filtration efficiency. Herein, we generate fibers by functionalizing silicone-based (polydimethylsiloxane, PDMS) fibrous membranes...

Poly(lactic acid) (PLA) fibers have found a broad range of applications in medical textiles. While traditional spinning methods usually involve harsh conditions, such as high temperature or toxic organic solvents, the challenges producing PLA via green route are yet to be overcome. Herein, we described new strategy for fiber production, which combines controlled and benign conditions enabled by microfluidics novel dope with bio-sourced CyreneTM non-toxic solvent PLA. This is in-situ...

Electrohydrodynamics (EHD) refers to the interaction of electrical forces with fluids, whether liquids or gases. EHD has established itself as an energy-efficient, highly versatile, and effective tool influence fluids without moving mechanical parts. Therefore, it found applications in various fields science engineering. This review paper categorizes most notable into five areas, grouping them based on their shared operational principles. The first application area includes electrospinning,...

The distribution of moisture in state-of-the-art firefighter protective clothing was analyzed on a sweating torso. After one hour sweating, only 35 % evaporated from the layers, but after another drying out, about 10 supplied remained clothing. Over 75 this accumulated innermost three layers system consisting five and six respectively. interaction transport properties different proved to be very important for moisture. In particular, neighboring layer underwear turned out dominant...
