This study investigates the filtration performance of three different filter media—PTFE (Polytetrafluoroethylene)-coated media, stainless steel fibre blended with PET (Polyethylene Terephthalate) media, and stainless steel fibre scrim media—under varying charge levels and dust concentrations using a pilot pulse-jet filter unit and a flat-based test rig. The effect of charge, material type, and dust concentration on filtration efficiency, particulate emissions, and charge dissipation behaviour is systematically examined. Results indicate that charge plays a dominant role in enhancing filtration efficiency by promoting dust agglomeration and improving dust cake properties. PTFE-coated media exhibits the lowest particulate emissions across both test rigs, whereas stainless steel fibre scrim media demonstrates the fastest charge dissipation. A comparative analysis reveals that the pilot pulse-jet filter unit exhibits higher particulate emissions than the flat-based test rig due to its non-uniform dust deposition and cleaning inefficiencies. The study further establishes strong correlations between downstream particulate emissions, mass concentration, and particle number concentration across the two test rigs. Findings provide valuable insights into optimising charge-assisted filtration mechanisms and understanding the influence of electrostatic charge on different filter media. © 2025, National Institute of Science Communication and Policy Research.

Seam strength is critical in achieving the proper and adequate quality seam, which eventually determines the overall quality of any garment. The target of this research was to investigate exactly how different stitch density affected seam strength for different stitch types. Commercially available, 100% cotton plain weave structured woven fabric with mass per unit area of 270 g/m2was used in this analysis. Two different stitch types, such as lock stitch (ISO#301) and chain stitch (ISO#401), along with four stitch densities like 8, 10, 12 and 14 per inch were utilized. The seam strength of the prepared samples was determined using a tensile strength tester followed by the ASTM D1683 standard procedure. The impact of independent variables on superimposed seam strength was statistically analyzed using a regression correlation with the help of SPSS software to construct a regression equation to predict seam strength before the manufacturing process. The study found a non-linear relationship between seam strength and stitch density. When the stitch density is too low, the seam strength is shown low as well, because the cloth cannot be held under tensile load. In a very compact woven fabric, structural jamming or intrinsic puckering occurs if it is too high. As a result, the best stitch density should be chosen to achieve the best seam strength. This study will help the manufacturers choose a suitable SPI for lock and chain stitches from polynomial regression equations before the sewing production of cotton woven fabric, which was not predicted by any researcher before. Therefore, the optimum stitch density can be chosen using regression equations to get the best result for seam strength. © 2022 The authors.

Multi-ply yarns have been used as the main structure to form strands, braids, and fabrics. Thus, various strategies including experimental, numerical, and analytical models have been utilized to predict their tensile behavior. In analytical models, all are limited to a specific number of fibers in an elastic region. The time-consuming experimental-based studies suffer from the accuracy of subjective results, associated errors of the experiment, ignoring the physical aspect of the problem, and practical issues during the controlling of variables. Concerning the numerical approaches, no insight into generalization is provided and they are bug-prone methods. In this study, a generalized method is developed to predict the whole tensile behavior of polyamide-6 (PA-6) multi-ply yarns with an open-packing structure. This approach is a combination of two geometrical models and an artificial neural network that enable the calculation of the deformation of fibers in different layers, the number of fibers in each layer by taking the gap into account, and an artificial neural network to map from parameters including strain and rate of strain to the reacting force on monofilament. The model has been verified by numerical analysis and examination of several factors including the number of layers, twist level, and rate of strain. After having trained ANN modeling with R2≈1, the proof-of-concept results demonstrated that this established model is capable of predicting the tensile behavior of PA-6 multi-ply yarns with high precision and accuracy (average value of R2=0.97 and MAPE=4.65%). It is envisioned that the presented model can be extensively applied to all yarns. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.

Different electromagnetic interference (EMI) shielding materials have been developed over time. In the past electromagnetic (EM) shielding technology made use of metals and their composites because of good shielding effectiveness but their low elasticity high density and corrosion tendency render them obsolete. Ceramic-based composites have also gained popularity for EMI shielding applications because of their low density and excellent corrosion resistance but high absorption loss is a major drawback. Recently, polymer-based composites have attracted attention because they make for superb EMI shielding with the advantages of electromagnetic wave absorption over reflection and have been widely used with fast growth in application after their emergence. This paper reviews the progress of polymer-based composites as efficient materials for electromagnetic interference shielding and applications. Electromagnetic (EM) waves are formed by the interaction of an electric field and a magnetic field. EM waves require no specific medium through which they can move. Their movement can be though air solid materials liquid or even vacuum. The EM spectrum ranges from lower energy waves (longer wavelengths) such as radio waves and microwaves to higher energy waves (shorter wavelengths), such as gamma rays and X-rays. Traditional materials such as metals and ceramics were found to be useful as EMI shielding materials. However, low elasticity high density and high absorption loss tend to limit their EMI effectiveness. Recently polymer-based electromagnetic shielding materials have been widely employed as EMI shielding materials. Given the above different EMI shielding materials based on diverse matrix materials are discussed with emphasis on polymer-based composites as emerging and alternative EMI shielding materials. The development of the electronic industry offers weight reduction as an additional technical requirement besides good EMI shielding performance. EMI shielding ensures

Cotton is the most widely used natural cellulosic polymer and polyester is a synthetic polymer. The use of polyester fiber is increasing gradually day by day due to its strength and longevity, while the use of cotton fiber is decreasing due to its unavailability. At present, the use of cotton-polyester composites is ubiquitous. This research work aims to assess the physical, mechanical and comfort properties of the woven fabric using cotton-polyester composite yarns in a weft direction and coarser yarn count because of the use of these fabrics in the future for the denim manufacturing process. Four different samples were fabricated by using 100% cotton (10 Ne) yarn in the warp direction and 100% cotton, cotton-polyester composite, and 100% polyester yarn in the weft direction of the fabric. Similar fabric and machine parameters were maintained for manufacturing all the samples. The samples were then tested for areal density, tensile strength, thickness, abrasion resistance and pilling, drape, flexural rigidity, and air permeability to find the optimum capability of the fabric. Physico-mechanical properties with the proportion of increasing polyester components in fabrics improves areal density (184 to 199 g/m²), strength (almost 19 times in weft direction), drape (0.655% to 0.789%), and flexural rigidity (almost double). On the other hand, increasing comfortability properties with the proportion of cotton components in fabrics improve air permeability (139.85 to 159.58 cc/s/cm²), abrasion (only 3.036% mass loss), and pilling resistance (grading 4 after 2000 cycles). Highlights: Composite yarns made of cotton and polyester provide a method of improving fabric properties for better performance. Higher proportions of cotton make clothes more breathable and less likely to pill and wear out. Polyester parts make fabrics stronger, more durable, and less likely to wear out. Cotton-polyester composites are ideal and have potential for various textile a

Owing to the increased emergence of viral diseases, microbial contaminations, micropollutants in the environment and ozone depletion, human health and safety concerns have extensively grown necessitating the need for effective protective measures. The research presents a protective nanocomposite fabricated by cellulose acetate nanofibers directly deposited on cotton base fabric for protection of human health from the microbial hazards, detrimental micro-contaminants and harmful UV radiations. The research aimed at development of the protective nanocomposite by a simple strategy to avoid otherwise used sandwiching and compression methodologies suggesting a wet-treatment method with a wetting agent. The nanocomposites were produced from biopolymers to ensure environmental sustainability and with higher filtration efficiencies, UV resistance and antimicrobial properties for safety and protection. The samples were characterized by SEM, FTIR, XRD and TEM analysis. The nanocomposite demonstrated 99.2% (without pneumatic-suction) and 97% (with pneumatic-suction) efficiencies contrary to conventional cloth which depicted only 98 and 0% efficiencies, respectively. Excellent bacteriostatic and bactericidal properties were confirmed by halo width measurement and cell viability analysis. The sample were able to demonstrate 95.1 and 96.4% bactericidal efficiencies against E. coli and S. aureus strains. The results showed quite low UVB and UVA transmittance and 50+ UV protection factor (AS/NZS4399). The calculated UV protection factor was 6388. Thus, the fabricated composite could be a potential candidate for protection against harmful microbial species, hazardous micro-contaminants and UV radiations.

A concern in the contemporary period is to find balance in the world's ever-increasing demand and its severely constricted output given by the present energy crisis brought on by the post-pandemic and ongoing Russia-Ukraine war. One of the most fundamental human needs is met by the production of textiles. Spinning is the first step in the production of textiles, where the ring frame machine is essential for creating yarn. In this study, a few process parameters were altered in a ring frame machine to boost production while saving time and ensuring financial feasibility. Comparative analysis was performed based on financial aspects as well as quality concerns like yarn count variation, Count Strength Product (CSP), and end yarn breakage rate. The increased machine speed of the spinning ring frame consumes higher energy but yields higher productivity without compromising quality parameters. The findings enable the spinning industry's decision-makers to understand better how process parameters change when machine speed varies, as well as offer policymakers a clear picture of the correlation between energy consumption and profitability. The machine produces roughly 420 kg/day consuming 567 kWh of energy at 14000 rpm, with 2.57% breakages/100 spindles/hour of 18.48 tex count variation and CSP of 1320. However, the production and energy usage of a machine at 15000 rpm, is approximately 449 kg and 630.44 kWh/day. Respectively, with breakages 3.06%/100 spindles/hour of count variation 18.62 tex and CSP of 1325. A potential increase in profit of 112.58 USD/machine/day, or 9682 BDT resulted from the increase in machine speed. © 2022 Universitat de Barcelona. All rights reserved.

Bitcoins and cryptocurrencies are in great debate these days. With its great market capitalization in 2020, after the COVID-19 outbreak, the attention of numerous investors has been attracted toward this new form of asset. So, we have been attracted toward the flair of this unforeseeable asset. In this paper, we have worked on the price OHLC (Opening, High, Low, and Closing) in a long span of time windows starting from its origin and have performed a comprehensive statistical analysis regarding the market value of Bitcoins in different time frames of last five years. Alongside that, we have validated its price using Weber’s law and have later supported our analysis using Zipf’s law. Though Weber’s law is well equipped to work in the branch of psychophysics, yet we have tried to extend its definition and have applied the law with a statistical essence in the well-fledged Bitcoin worth dataset. Finally, to support our analysis, we have also validated the price of Bitcoins using Zipf’s law and discussed some advantages of applying Weber’s law over Zipf’s law. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Nanoindentation technique was used to investigate the mechanical properties of polypropylene/multi-wall carbon nanotubes (MWCNT) nanocomposite fibers. The hardness and elastic modulus of the nanocomposite fibers were evaluated as a function of MWCNT concentration. It was found that incorporation of MWCNT enhanced the hardness and elastic modulus of the fibers. The elastic modulus data calculated from indentation load–displacement experiments were comparable with those obtained from tensile tests. DSC results also confirmed the increase in crystallinity of the polypropylene fibers due to the addition of MWCNT. The studies indicated that nanoindentation was a simple but efficient test method for evaluating the mechanical properties of nanocomposite fibers. © 2020, The Institution of Engineers (India).
