... To explore the effect of structure parameters on the air permeability of parachute fabric, the parachute fabric was treated as a porous medium. A nonlinear model of the viscosity and the inertia coefficient of the parachute fabric was established based on the Ergun formula, and an an alytical model of the fabric permeability with the fabric structure parameters was established considering the air ...
... This paper presents the fabrication and characterization of laser-treated conductive cotton fabrics by means of copper metallization techniques. The physical properties of the laser-treated knitted samples were examined in terms of thickness, durability, and abrasion impact. Furthermore, the surface topography of the laser-treated substrates was analyzed using a scanning electron microscope (SEM) ...

Abstract:
... Cotton is the most popular natural fiber used in apparel industry world over. Although cotton is cultivated in approximately 2.4% of the world’s arable land, it accounts for 24% of the world’s insecticide market. Industrial hemp is considered as the most sustainable raw material as substitute of cotton in textile industry. However, there are several challenges associated with hemp processing as th ...
... Among insects, female oviposition preferences are critical to understanding the evolutionary dynamics between herbivores and hosts. Previous studies have shown than in Drosophila, resource use has a strong genetic basis, although there is evidence that preferences are adaptable given isolation from ancestral hosts. Given the high degree of adaptability and behavioral plasticity of invasive species ...
... In this article, the breaking elongation properties of woven fabrics with incorporated PBT yarns are presented. Different polybutylene terephthalate (PBT) yarns (multifilament PBT yarn, cotton core yarn and twisted viscose yarn, both with PBT in the core) were used. Textured PBT yarns have latent elastic properties, which become visible after the thermal treatment by the finishing process. The aim ...
... There is increasing growth in research of the development, upgrading and valorization of forestry and agriculture-derived products for applications in fuels, chemicals, and materials. Many biochemical and thermochemical biomass conversion technologies yield unique products for which laboratory characterization of structure and properties is still an ongoing challenge. Historically, popular approac ...
... This paper primarily describes the development of flax braided yarn fabric reinforced thermoplastic composites. Plain woven fabric is made by interlacing 3D braided yarn produced by solid braiding method. Tensile properties of braided yarn and woven fabric are evaluated. Solution casting is used prior to composite fabrication to prepare polylactic acid (PLA) and (natural fiber braided fabric) NFBF ...

Abstract:
... Lungs are the primary interface between the atmosphere and working tissues and act as the primary metabolic machinery of the body. The gas exchange that occurs inside the lungs through alveoli ensures adequate supply of oxygen to the tissues and determines the physical and physiological well beingness of the individuals. Barometric pressure decreases as altitude increases and individuals performin ...

Abstract:
... The almond crop has high economic importance on a global scale, but its sensitivity to salinity stress can cause severe yield losses. Salt-tolerant rootstocks are vital for crop economic feasibility under saline conditions. Two commercial rootstocks submitted to salinity, and evaluated through different parameters, had contrasting results with the survival rates of 90.6% for 'Rootpac 40' (tolerant ...
... New Polyacrylonitrile (PAN) nanoclay hollow fiber membranes were successfully fabricated through the dry-jet wet spinning process. The effects of adding the nanoclay on the hollow fiber mechanical properties and permeation performance and dye removal from water were investigated. Direct red 80, Direct orange 26 and Direct brown 2 dyes were used for dye removal experiments. Field emission scanning ...
... This study evaluates the effects of different aqueous borax solutions on the morphology, mechanical, thermal and chemical properties of regenerated cellulose fiber woven fabric reinforced hydrogel composites. The fabric reinforced hydrogel composites were fabricated with PVA/viscose ring, PVA/viscose open-end (viscose OE), PVA/viscose continuous filament (viscose CF) blended woven fabrics. Mechani ...

Abstract:
... Herein, a novel direct Z-scheme photocatalyst was accomplished by hybridization of 0D MoS₂ quantum dots (MSQDs) and 3D honeycomb-like conjugated triazine polymers (CTP) (namely, CTP-MSQD). The unique 0D/3D hierarchical structure significantly enhanced the exposure of active sites and light harvesting property, while the formed p-n junction enabled the direct strong interface coupling without the n ...
... Polycyclic aromatic hydrocarbons (PAHs) and their oxygenated derivates (O-PAHs) are identified in soils and groundwater of industrialized sites and contribute to the risk for Humans and the Environment. Nevertheless, data are scarce in literature concerning their retention and transfer in soils and no soil - water partition coefficients are available for these compounds. Sorption of two PAHs, fluo ...

Abstract:
... Approximately 94 to 220 million people worldwide are at risk of drinking well water containing arsenic > 10 µg/L, the WHO guideline value. To identify non-compliant domestic wells, assess health risks and reduce exposure, accurate and rapid on-site inorganic arsenic screening methods are desirable because all domestic wells worldwide need to be tested. Here, the principles, advantages and limitati ...
... In this study, a mathematical model has been developed to simulate the through-air drying process of yarn bobbins. For this purpose, experimental data was obtained in a prototype experimental set up by passing pressurized hot air through the wool yarn bobbins. First of all, the physical phenomenon expressing the drying process has been reduced to the heat transfer problem and then a mathematical m ...

Abstract:
... Co-exposure to heavy metal and antibiotic pollution might result in complexation and synergistic interactions, affecting rice growth and further exacerbating pollutant enrichment. Therefore, our study sought to clarify the influence of different Tetracycline (TC) and Cadmium(Cd) concentration ratios (both alone and combined) on rice growth, pollutant accumulation, and transportation during the til ...
... Triclosan (TCS) is a ubiquitous antimicrobial used in daily consumer products. Previous reports have shown that TCS could induce hepatotoxicity, endocrine disruption, disturbance on immune function and impaired thyroid function. Kidney is critical in the elimination of toxins, while the effects of TCS on kidney have not yet been well-characterized. The aim of the present study was to investigate t ...

... Scorodite (FeAsO₄·H₂O) is a common arsenic-bearing (As-bearing) iron mineral in near-surface environments that could immobilize or store As in a bound state. In flooded soils, microbe induced Fe(III) or As(V) reduction can increase the mobility and bioavailability of As. Additionally, humic substances can act as electron shuttles to promote this process. The dynamics of As release and diversity of ...
