Human-machine interfacing (HMI) systems are essential components of daily life integrating technology into our routines by enabling intuitive interaction with various devices and systems. The advancement of smart textiles and wearable devices has led to a growing demand for flexible human-machine interfaces (HMIs). In this study, a multifunctional textile HMI is introduced. Conductive silver-coated nylon yarn was embroidered onto polyester woven fabric with a comb-like structure. The embroidered fabric was subsequently covered with a thin layer of Polyvinylidene Fluoride (PVDF) polymeric film/nanofiber, resulting in a triboelectric nanogenerator(TENG) structure. When interacting with a finger, this structure operates under both free-standing and single-electrode TENG principles. Signals generated from hand-finger sliding and tapping motions show that the nanofiber-coated sample produced a higher voltage, reaching up to 40V, and exhibited greater power output. In contrast, the polymeric film displayed more durability but generated a voltage of up to 10V. © 2024 Fraunhofer IZM.

Energy crisis is a serious problem caused by limited nonrenewable resources, climate change and population growth. It is needed to find ways to harvest energy from renewable sources. One of them is mechanical energy, which can be converted into electricity by using piezoelectric or triboelectric effect. However, piezoelectric conversion has low efficiency and complex fabrication. Triboelectric nanogenerator (TENG) is a better alternative, as it has high output and low cost. It can be made of common materials like polymers, metals and fabrics. This paper introduces and analyzes a gym floor TENG (GFTENG) that uses gym floor mats to harvest electrical energy from human footsteps. The performance of GF-TENG under various environmental and structural conditions like footstep frequency, the gym flooring mat and the foot state were studied by measuring the output voltage and current density of the GF-TENG. Maximum output voltage and current density was obtained as 50 V and 140 μ Am-2. The GF-TENG device can light up 10 green commercial LEDs in series just by jumping a 50 kg weight person on it with the contact area of approximately 345 cm2. Regarding to different output voltage peaks for distinct activities such as walking, jogging, running and jumping it can also be a self-powered footstep motion sensor. © 2024 IEEE.

The polyester dyeing is considered crucial among the apparel grade fibers due to physical penetration of dye particles in the molecular structure of the fibres. The effect of various dyeing procedures namely dope dyeing, high-temperature high pressure (HTHP) fiber dyeing, fabric carrier dyeing, and HTHP fabric dyeing on low-stress mechanical characteristics of polyester woven fabrics was targeted for the study. The fibre samples were subjected to thermal, X-ray, and tensile characterization while fabric samples were subjected to analyse for low-stress mechanical properties by Kawabata Evaluation System (KES-FB). The study revealed that the polyester dyeing with disperse dye could create sufficient movement in molecular chains at polyester dyeing temperature (130 °C), significantly influencing low-stress mechanical properties. Polyester fiber and manufactured yarn modulus reduces after HTHP dyeing, which was reflected at fabric stages by alteration in low-stress mechanical properties. The fabrics manufactured with dope-dyed fibers show a considerable resistance against low-stress compression. The blank carrier dyed fabric sample shows total hand value of 3.97 for winter application. The dyeing process made polyester fabrics more appropriate for winter applications, while grey polyester fabrics were suitable for summer wear. © 2022, The Institution of Engineers (India).

This paper reports the effects of fiber breakage defects and waviness defects on the compressive fatigue behavior and the progressive damage evolution process of 3D Multiaxial Braided Composites (3DMBCs). Combined with finite element compression simulation and ultra-depth microscope, the internal defect content of composites with different braiding angles was determined. The results demonstrate that the weakening effect of waviness and fiber breakage defects is greater than the strengthening effect of the braiding angle. This causes the fatigue resistance of 3DMBCs with the 31° braiding angle being better in both directions of 0° and 90°. The increase of 4° waviness and 10% fiber breakage defect results in the average fatigue life of composites being shortened by 48% and the energy consumption rate increased by 10% at 85% stress level in 90° compression direction. The alteration in loading direction modifies the included angle corresponding to the stress component. The stress component parallel to the fiber direction under compressive fatigue load leads to interfacial debonding in the composites, whereas the stress component perpendicular to the fiber direction results in pronounced shear failure.

Correlating processing induced orientation with tensile properties for mass polymerized acrylonitrile butadiene styrene test specimens

RSC Applied Polymers

RSC Applied Polymers 2024年第6期2卷 1032-1042页

In this research, we deal with the link between tensile properties and processing-related morphology variations for mass polymerized acrylonitrile butadiene styrene (mABS). The orientation of multi-core polybutadiene (PB) particles, which are intrinsic to mABS, is investigated regarding flow, shear and cooling changes during sample production. The effect of a different sample size and annealing on the tensile responses has been verified by considering ISO 527 1A and 1BA dog bone samples. For the thin 1BA bars, multiple injection velocities and cooling rates during injection molding have been tested to obtain a more pure correlation between morphology and tensile properties. To perform comparable tensile measurements using both types of dog bone samples, a testing method has been designed for which a relation is included between the sample gauge length and cross head velocity, enabling the comparison of elastic deformation for ISO 527 1A and 1BA mABS samples. Regarding the mABS part morphology, injection molded parts display a skin-shear-core gradient morphology with respect to the PB-particle size and orientation. Annealing of both types of injection molded samples successfully removes most flow-induced orientation of the rubber particles but also results in a change in PB morphology by dissolving a small fraction of the rubber into the SAN matrix, forming PB-nanoparticles. These small particles promote shear bands upon craze-based deformation and therefore positively contribute to the sample toughness. High flow-induced orientation within mABS parts causes a significantly increased tensile stiffness, strength and toughness along the flow direction. Irrespective of the PB orientation, tensile bars with a large surface roughness experience early failure, due to premature craze and crack initiation at the sample surface. © 2024 RSC.

Road accidents are one of the major contributors to mortality in India with nearly 1.68 lakh deaths in 2023 accounting for nearly 19 deaths per hour. While road accidents aren’t always “fatal”, delayed detection leads to the loss of many lives. Deep Learning deliberately showed terrific results for a lot of tasks, but for a long time, the Deep Learning models utilized the standard Multi-Layered Perceptron (MLP) architecture as its’ skeleton. Recently, a state-of-the-art architecture—Kolmogorov Arnold Network (KAN) showed up, with variable activation functions in each edge of the graphical representation of the network. Several works have inherited the KAN architecture and have shown better results in many instances. This research proposes a class of accident detection models, SADAK (Simple, and Automatic Detection of Accidents on roads using Kolmogorov–Arnold Networks) for detection of road accidents inheriting KAN architecture. To benchmark its efficiency, several well-known MLP based architectures have been considered, alongside some state-of-the-art models, which result in accuracies as high as 89% using the MLP (Vision Transformer), and 97% using the KAN architecture (KAN-Convolutional-MLP). © Bharati Vidyapeeth's Institute of Computer Applications and Management 2024.

Analysis of the Outer Layer Performance of Fire Protective Clothing

Textile and Leather Review

引用

textile and Leather Review 2024年 7卷 366-390页

作者： Rathour, Rochak Maurya, Sudhanshu Das, Tathagata Rajput, Bhavna Das, Apurba Alagirusamy, Ramasamy Department of Textile and Fiber Engineering Indian Institute of Technology Delhi Hauz Khas New Delhi India Department of Mechanical Engineering Indian Institute of Technology Delhi Hauz Khas New Delhi India

In the present study, an attempt has been made to analyse the protection performance of fire-protective clothing. Various exposures to the same fabric in different configurations result in different protection performances. Box-Behnken experiment design was used to optimize the process parameters such as pick density (P), heat flux (Q), and air gap (D). Through surface methodology response, the relationship among the process parameters such as pick density (P), heat flux (Q), and air gap (D) was established. The experimental multi-parametric equation for calculating the radiant protection time (RT) and flame protection time (FT) was acquired. The fabric used was developed with 2/40 Ne Nomex IIIA yarns. The pick density (P) ranged from 40 to 64 picks per inch, heat flux (Q) ranged from 0.5 to 1.5 cal/cm2/sec, and air gap (D) ranged from 0 to 25 mm. To experimentally determine the level of protection, Stoll criteria were used. The experimental and predicted protection time values show a high correlation coefficient value (R2 = 0.985 for radiant and 0.978 for flame). The maximum improvement in protection was obtained at a high level of air gap (25 mm), low level of heat flux (0.5 cal/cm2/sec) and low level of pick density (40 picks per inch). Obtained results, calculations and equations will help researchers explore the empirical equation of the Box-Behnken model and other surface response curves. The values of protection time, in the specified range of the process parameters, by a single calculation could be possible to obtain. © 2024, idd3. All rights reserved.

Wickability of Soil Slurry by Jute and Coir Yarns

引用

Journal of The Institution of Engineers (India): Series E 2025年第1期106卷 57-68页

作者： Woyessa, Temesgen Regassa Chattopadhyay, R. Mhaski, Sourabh Ramana, G.V. Department of Textile and Fibre Engineering Indian Institute of Technology Delhi Hauz Khas New Delhi110016 India Department of Civil Engineering Indian Institute of Technology Delhi Hauz Khas New Delhi110016 India

The wickability of jute and coir yarns have been investigated using standardized soil slurry (soil mixed water). In many geotextile applications, the yarns constituents of a geo-fabric are exposed to slurry in order to drain out the water through their structures under variety of state i.e. vertical, horizontal and bent configurations. Wickability of the geo-textile yarn is extremely important for drainage applications. Wickability of two commonly used natural fibre yarns (Jute and coir) was therefore assessed, under vertical, horizontal, and syphon configurations using normal tap water, and slurries made from Delhi silt and Kaolinite. The wicking parameters (maximum wicking height/distance and wicking rate) and water discharging capacity of the yarns were determined. Soil slurry was found to adversely affect wicking performance in comparison to normal tap water. The slurry discharge rate, normalized over yarn linear density, was found to be greater for jute yarn in comparison to coir yarn. The intrusion of soil particles into the yarn structure clog the capillaries and adversely affect the wickability and discharge with time. © The Institution of Engineers (India) 2024.
