Fluid transfer through materials is very important when dealing with materials that are in direct contact with human skin, such as materials used in the manufacture of sportswear. The ability of this group of materials to control this transfer in a defined way directly affects human comfort, which is now considered a must for optimal human performance. The results of the studies published to date point to certain influential parameters, including the material mass and thickness, the cross-section of the multifilaments, and the material pattern. For this research, a series of materials differing in yarn parameters were designed and fabricated. Water vapour permeability, wetting time, drying time, and wetting area are measured to compare the properties of the designed materials that describe the ability of the materials to transfer liquid. The results of the measurements are discussed in the context of the product application. It is shown that the recycled material has the highest value for water vapour permeability, but does not show different behaviour in terms of wetting time. It is also confirmed that the raw material has a greater influence on the water vapour permeability results than the thickness or the mass per unit area. © 2023 IEEE.

Unmanned aerial vehicles (UAVs) are used in many industries thanks to their beneficial characteristics and propellers are one of the most important components of UAVs. Propellers transform rotary motion into linear thrust and they generally provide lift and thrust to the UAV by spinning and creating an airflow, which results in a pressure difference between the top and bottom surfaces of the propeller. During the life cycle of the propellers, they may receive impact loadings as a result of hard landings or bird strikes. Therefore, impact damage can occur in UAV propellers. Due to that reason, the impact resistance of the propellers must be improved. In this study, a composite material is designed to be used in the manufacture of UAV propellers. Polyamide 6 (PA6) is selected as the matrix material thanks to its superior abrasion resistance, outstanding dimensional stability, and high specific tensile strength. In order to improve the impact resistance of the PA6, olefin block copolymer (OBC) and carbon-based reinforcement including carbon nanotube (CNT) are planned to be used. Following the development of the composite formulation, composites are going to be manufactured and tensile tests, Charpy impact, and hardness tests were carried out to determine fundamental mechanical properties. Finally, optical microscopy was used to examine the CNT distribution in the manufactured composites. © 2023, The Society for Experimental Mechanics, Inc.

Chronic exposure to ultraviolet (UV) radiation can cause degenerative changes in the cells, fibrous tissues and blood vessels. Moreover, microbiological attacks pose severe risks to human health and are a major cause of sickness worldwide. The aim of this work is to develop UV protective and antimicrobial materials using zinc oxide (ZnO) colloidal solution with carrot and orange peel extract. Treated samples were subjected to color strength (K/S value) measurement, scanning electron microscope (SEM) image analysis, attenuated total reflectance (ATR) Fourier transform infrared (FTIR) spectroscopy analysis, ultraviolet protection factor (UPF) test, bacterial reduction rate analysis and bursting strength measurement. The study revealed that the treated fabric exhibited remarkable UV protection capabilities, as evidenced by low transmission percentages across UV wavelengths and an outstanding UPF rating of 50, signifying excellent defense against harmful ultraviolet radiation. Additionally, antibacterial tests revealed the significant effectiveness of the treatment against common bacterial strains, with impressive reduction rates for Staphylococcus aureus (99.99%) and Escherichia coli (99.17%). Furthermore, the fabric's bursting strength, both in dry and wet conditions, remained nearly unchanged after treatment. ATR-FTIR analysis and SEM imaging provided insights into the phytochemical compounds that give protection against UV composition (44.63–49.91) and surface morphology of the treated fabric, elucidating the mechanisms behind its enhanced properties. Due to the availability of carrot and orange peel in nature and low cost of raw materials, this process can be considered to apply commercially for further research purposes. Highlights: Utilization of carrot and orange peel waste. Successful application of zinc oxide for antibacterial and ultraviolet protective materials. Excellent defense against harmful ultraviolet radiation. Significant effectiveness against common

Natural dyes serve as a benign alternative to their synthetic counterparts, offering a sustainable option that directly mitigates the release of toxic chemicals. In this study, cotton fabrics were dyed with neem leaf extract in acidic, neutral and alkaline condition where samples were mordanted with lemon juice. The findings revealed a direct correlation between colour strength (K/S) and pH levels, and optimal fastness properties were achieved under alkaline pH conditions when a mordant was employed. The Energy Dispersive X-ray (EDX) ensured the elemental composition of lemon juice assisted dyed fabric which indicates the effective binding of cotton fabric with neem leaves extracted dye. The Fourier Transform Infrared (FTIR) Spectroscopy analysis also confirmed the interaction of cotton fabric with dye particles. The results indicate that cotton fabric can be successfully dyed with neem leaf extract and lemon juice as the biomordant, presenting an eco-friendly and sustainable approach to dyeing practices. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

Stab-resistant textiles play a critical role in personal protection, necessitating a deeper understanding of how structural and layering factors influence their performance. The current study experimentally examines the effects of textile structure, layering, and ply orientation on the stab resistance of multi-layer textiles. Three 3D warp interlock (3DWI) structures ({f1}, {f2}, {f3}) and a 2D woven fabric ({f4}), all made of high-performance p-aramid yarns, were engineered and manufactured. Multi-layer specimens were prepared and subjected to drop-weight stabbing tests following HOSBD standards. Stabbing performance metrics, including Depth of Trauma (DoT), Depth of Penetration (DoP), and trauma deformation (Ymax, Xmax), were investigated and analyzed. Statistical analyses (Two- and One-Way ANOVA) indicated that fabric type and layer number significantly impacted DoP (P 0.05). Further detailed analysis revealed that 2D woven fabrics exhibited greater trauma deformation than 3D WIF structures. Increasing the number of layers reduced both DoP and DoT across all fabric structures, with f3 demonstrating the best performance in multi-layer configurations. Aligned ply orientations also enhanced stab resistance, underscoring the importance of alignment in dissipating impact energy. © 2025 China Ordnance Society

Natural dyes offer a harmless alternative to synthetic counterparts, minimizing the release of toxic chemicals associated with synthetic dyes. In this investigation, nylon fabrics underwent dyeing with neem leaf extract under acidic, neutral and alkaline conditions along with lemon juice mordant. The study revealed that colour strength exhibited an increase with decreasing pH levels, with the mordanted fabric dyed in an acidic medium demonstrating the highest value. Analysis of colour coordinates indicated that the mordanted fabric dyed in an acidic medium exhibited superior colour pickup compared to the other samples. Enhanced fastness properties were achieved under acidic pH conditions when a mordant was used. The FTIR test result ensured the nylon-lemon juice-neem leaves extracted dye interaction. The EDX analysis also confirmed the elemental composition of neem leaves extracted dye in nylon assisted by lemon juice. The SEM test results validated the dyeing process empirically. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

The demand for superhydrophobic fabric with self-cleaning and antibacterial features as potential practical applications has been rising steadily with the passage of time. In this research work, the wet chemical method is used to manufacture cotton with a superhydrophobic coating. Thus, Nanoparticles of silver were produced by using an in situ method. Afterward, the fabric is treated with a solution of perfluorooctyltriethoxysilane to make it superhydrophobic. The cotton fabric performs remarkably with exceptional hydrophobicity as it had a contact angle of 157 ± 1° and less than 10° in sliding angle. Water droplet's dynamic behavior is also studied so that the superhydrophobic fabric development can be proven. The fabric shows excellent chemical durability by performing chemical tests. The antimicrobial and self-cleaning properties are greatly enhanced by the superhydrophobic coating on cotton. Particle density on the superhydrophobic cotton before and after self-cleaning was found 5.1 and 0.4 mg/cm². In addition, the treated cotton fabric also exhibited superior antibacterial properties against Escherichia coli bacteria. Therefore, the developed multifunctional cotton fabric can be used in real-life applications. Highlights: Cotton fabric enables to repelling of dirt, oil, and water-based stains more effectively. Silver nanoparticles possess potent antibacterial properties. Incorporation of PFOTS controls the release of silver into the environment. Versatile applications from healthcare and hospitality to outdoor and athletic apparel. © 2024 The Author(s).
