This study explores the slash resistance of soft armor, underscoring the essential need for enhancements in fabric design and fiber properties. Yarn-slicing qualities and the fabric's pattern play pivotal roles in the fabric-cutting mechanism. The fabric stabbing resistance force demonstrates strong positive correlations with multiple factors, encompassing values such as friction force between warp and weft, yarn cutting force, yarn pull-off force, fabric shear modulus, and fabric flexural stiffness. The investigation explores the relationship between slash resistance in high-performance fabrics, revealing a robust correlation with factors such as yarn cutting force, yarn pull-off force, fabric shear modulus, friction force between warp and weft, and fabric flexural rigidity. Fabrics constructed from Kevlar 129 or 29 showcase the highest slashing resistance force. Experimental results unveil that the Kevlar 129 plain weave exhibits the utmost resistance, recording a force of 100.37 N and a fabric-slashing energy of 3.65 J. In contrast, the Kevlar 29 plain weave structure withstands a slash resistance force of 67 N, while the Kevlar 29-carbon plain weave displays a slash resistance of 62.97 N. The correlation coefficients between various variables linked to fabric-slashing resistance force unveil a strong, positive, and highly interrelated association for the majority of factors investigated. These factors encompass yarn-cutting force, yarn pull-off force, fabric shear modulus, and fabric flexural rigidity. Additionally, there exists a positive correlation with the friction force between warp and weft.

Bag filters play a crucial role in mitigating these emissions by capturing particulate matter and improving air quality. However, conventional bag filters eventually wear out and need replacement, leading to a significant environmental burden from discarded filter materials. This study explores a sustainable approach to address this issue by investigating the potential of recycling used bag filters from the cement industry. The focus of the investigation is on fabric/polymer or fabric/cement composite materials, which exhibit promising properties for recycling applications. The research begins with an in-depth analysis of the discarded bag filters. This characterization enables the selection and optimization of suitable recycling processes for fabric/polymer or fabric/ cement composites. Furthermore, the study evaluates the performance of recycled fabric/polymer or fabric/cement composites as alternatives to conventional methods of bag filters in cement recycling and mechanical parameters of the airbag filter when used as reinforcement in the polyester matrix or cementitious composites. In conclusion, recycling bag filters of the cement industry in fabric/polymer or fabric/cement composite materials offers a promising avenue for reducing waste generation and enhancing resource efficiency. The study underscores the importance of transitioning towards circular economy principles in industrial processes. Recycling bag filters in the cement industry is a sustainable approach that supports environmental responsibility and contributes to the circular economy. It helps conserve resources, reduce waste, and minimize industry's impact on the environment.

In this paper, the penetration of a puncher through a plain Kevlar woven fabric was analyzed to recognize the process of punching and the mechanism of yarn breakage. The model focused on the study of the difference between fabric that is woven from the continuous multifilament yarn or the spun yarn and the effects of their yarn structure on punching resistance. The relation between the warp and weft yarns and the punching resistance force of the fabric at different punching speeds was investigated. This work focused on the potentiality to use fabric from coarse Kevlar spun yarns instead of continuous filament yarns to enhance the punching resistance. Samples of fabrics were tested on a specially designed set-up to investigate the behaviour of warp and weft yarns under punching load.

The volume also addresses the important issue in the materials science of how to utilize natural fibers as an enhancement to composite materials. Natural fiber-reinforced polymer composites have been proven to provide a combination of superior mechanical property, dielectric property, and environmental advantages such as renewability and biodegradability. Natural fibers, some from agricultural waste products, can replace existing metallic and plastic parts and help to alleviate the environmental problem of increasing amounts of agriculture residual. The book is divided into four sections, covering: • applications of natural fiber polymer composites • design of natural fiber polymer composites • composite manufacturing techniques and agriculture waste manufacturing • composite material testing methods The first section of the book deals with the application of textile composites in the industry and the properties of the natural fibers, providing an understanding of the history of natural fiber composites as well as an analysis of the different properties of different natural fibers. The second section goes on to explain the textile composites, their classification, different composite manufacturing techniques, and the different pretreatment methods for the natural fibers to be used in composite formation. It also analyzes the composite material design under different types of loading and the mechanism of failure of the natural fiber composite. The effect of the fiber volume fraction of different textile structures is explained. The third section of the book, on composite manufacturing techniques and agriculture waste manufacturing, concerns the natural fiber composite manufacturing techniques, agricultural waste, and the methods of their preparation to be used successfully in the composite, either in the form of fibers particles or nanoparticles. The book then considers the testing methods of the different composite components as well as the final composite materials, giving the principle of the testing standards, either distractive or nondestructive. This book attempts to fill the gap between the role of the textile engineer and the role of the designer of composites from natural fibers. It provides important information on the application of textile composites for textile engineers, materials engineers, and researchers in the area of composite materials.

Additionally, they are key ingredients to improving student acquisition of knowledge. For the assessment to be effective, an incentive must be tied to the achievement or the process becomes meaningless. A predominant incentive is a negative approach, in which the student will suffer negative grade consequences if they do badly on the assessment. This negative reinforcement has been proven to be short-lived and requires much more effort to maintain as an incentive than its positive counterpart. One of the most successful positive reinforcement mechanisms known is gamification. In these systems the learning process is turned into a game with a positive reward system. Historically, implementing such a gamification system was very difficult to achieve due to the inadequacy of supporting technology. In this research, we propose a novel approach of using Non-Fungible Tokens (NFTs) as an incentive mechanism tied to student assessments to positively incentivize both students and their teachers. Our approach allows positive incentive reinforcement through the bragging rights and special access to benefits granted to the NFT holders. We also demonstrate how effective and cost-efficient this new system is.

Most of the technical advances in ring spinning were aimed at improving the performance of the existing technology. In this study, air atmospheric plasma was used for improving wetting of cotton yarn using modified electrodes. Certain physical properties such as yarn tenacity, yarn hairiness, were evaluated as well. The outcomes revealed a remarkable increase in cotton wetting ability of compact spun yarns after the atmospheric plasma treatments. The results also pointed out that with the atmospheric plasma treatments of compact yarns give the percent of the liquid absorptive capacity for untreated and treated compact yarn is found 38 % and 105 % respectively. Therefore the percent increase in LAC is found 175 %. Atmospheric plasma treatment doesn't have significant negative effect on yarn properties not significant at 1% level.

Along their own histories, every civilization developed and evolved its own fashions and trends to address the different circumstances they encountered. The common aspect between all of them is the dependency on mixing raw materials to begin the spinning process. The complex nature of the materials used renders creating a fully qualified mathematical model that can capture the exact process virtually impassable. This is the fundamental reason that the current process still relies on humans to render a judgment call for which materials to mix. A prime example of that is mixing cotton balls to supply the spinning production line. This process is both unreliable as much as it is not scale-able. Two main schools of thought developed to address this issue. The first attempts to grade the mix using a color scale, while the second utilizes a regression formula to arrive at an index measurement. Both approaches are depending on an old approximation of the underlying process. In this work, a novel approach is presented to resolve the issue by mapping it to a classification problem and utilizing artificial intelligence models to learn and predict the outcome of mixing the cotton balls. Six different algorithms are implemented, tested and evaluated to determine the suitability for the underlying domain. Finally, demonstrate that artificial intelligence can be applied to evolve the current process with high reliability and accuracy.

In this research work, series of Triaxial fabrics are prepared using Polyester, Kevlar 29 and Vetran. The effect of material type on quasi-static puncture resistance is studied comparatively. The failure mode of the fabrics is analyzed. Findings indicate that the material type affects the quasi-static puncture resistance property of Triaxial fabrics. The contact pressure of fabric-probe represents the main resistance during the quasi-static puncture processes leading to the breakage of the fibers under penetration of the probe caused by tensile stress. The puncture resistance of the triaxial fabric/polyester composite was enhanced through the adding of a certain percentage of glass nanoparticles to the polyester polymer. The polyester/glass Nanoparticle matrix show better puncture resistance than ordinary polyester polymer matrix. The analysis of the results of the punching stress and the punching energy of the triaxial fabric/polyester/glass Nanoparticles composite is enhanced due to the application of the hybrid polyester/glass Nanoparticles using 2.8% glass particle volume fraction.

Several systems are introduced to produce such yarns which have better physical and mechanical properties than the ring spinning. All the systems for the production of compact spun yarns consist of a modification of the drafting system on the ring spinning machine, so that the spinning triangle dimensions decreases. The properties of compact spinning were thoroughly investigated by several researchers. The results of their studies indicated that compact spun yarn strength is higher by about 15% and elongation at break by about 20%. Furthermore, the yarn hairiness becomes 70% less, and the coefficient of variation of the yarn was lower by 15% than that for the equivalent ring spun yarn. These advantages can reflect on the downstream processing. In this work a comparative study has been carried out to investigate if the compact fine ply carded yarn spun from Egyptian cotton G86 will have better quality than combed ring spun yarns. The results indicate that through the adjusting the production speed of the carding machine the carded compact yarns for the counts up to Ne 80/2 give better quality in comparison to the combed ring spun yarns.
