In this study, 32 different electro-conductive fabrics and seven non-conductive were taken for an analysis of their electromagnetic shielding ability, electrical resistivity air permeability. According to the present state development textile structures, a diverse set samples was selected, including stainless steel, copper, silver, aluminum, carbon polypyrrole as conductive component. The ASTM D4935 coaxial transmission line method used study D257 ring electrode evaluate surface volume all...
Insulation offers thermal comfort by blocking the heat flow across walls of buildings and drastically reduces cost associated with energy consumed in maintaining temperature inside buildings. Commercial insulating materials such as fiberglass, polystyrene, polyurethane foams, although demonstrating long serviceability, are several limitations including non-biodegradability. This study hence presents development biodegradable multilayer nonwoven fabrics based on natural fibers for insulation...
Expanded graphite (EG) has been used to store phase change materials (PCM) enhance thermal conductivity and avoid leakage. However, systematic investigation on physical structure of various embedded PCMs in EG is not reported. Besides, the effect environment behavior PCM/EG composites investigated yet. In this work, three common (including myristic acid (MA), polyethylene glycol (PEG) paraffin wax (PW)) were obtained. As a result, capillary force between supported encapsulation EG. had...
Advancement in technology has miniaturized electronic gadgets capable of functioning at a high speed, especially world pitching toward 5G. With the growing demand for electronics as well small portable devices, electromagnetic pollution is precipitously emerging critical problem affecting human health and environment. Electromagnetic interference (EMI) radiation particular causes multiple concerns, ranging from malfunctioning data to its effect on performance also can affect functions body....
The objectives of the present study were to develop an environmentally friendly, low-price, easy, and fast method for developing antipathogenic (antibacterial, antifungal, antiviral) cuprous-oxide-coated multifunctional fabrics. fabrics first sensitized with citric acid, then Cu2O particles formed using Fehling solution method. cuprous oxide applied cotton To create particles, three different kinds reducing agents varying concentrations used. SEM, dynamic light scattering, FTIR, EDS, XRD...
Electromagnetic (EM) radiation is everywhere in this world and galaxy different forms levels. In some cases, human beings need to protect themselves from electromagnetic radiations the same thing also recommended for electronic devices as well. Lots of studies are there on shielding interference using metals, polymers, minerals. For protecting being, textile structures playing main role. material structure itself many types there; each one having its unique geometrical shape design. work,...
Nowadays, electrically conductive textile materials are widely used also for sensing applications in addition to being as antistatic, electromagnetic shielding, creating smart textiles, etc. The main aim of this paper is study the effect tensile deformation applied on knitted fabrics their shielding ability, electrical resistance, and porosity gain knowledge construction textile-based wireless strain sensors. For experiment, silver-coated yarn was chosen produce with two different patterns...
Textile-based electromagnetic interference (EMI) shielding materials with good flexibility and high EMI effectiveness (SE) are highly desirable. Still, the poor mechanical properties of textile-based limit their application. The carbon filaments (CF) combine superior conductivity. Therefore, we demonstrate CF-reinforced material, which was laminated two types copper-coated nonwoven polyester (CuPET10 CuPET20) for shielding. Compared to traditional lamination method, this process more...
Abstract Electromagnetically shielding textile materials, especially in professional or ordinary clothing, are used to protect an implanted pacemaker the body. Alternatively, traditional textiles known for their non-conductivity and transparency electromagnetic field. The main goal of this work was determine whether high moisture content (sweat) structure significantly affects resulting ability material shield Specifically, sufficient wetting can increase its electrical conductivity match...
This study was focussed to investigate the effect of fluorocarbon, hydrocarbon and hybrid fluorocarbon on mechanical properties moisture regain jute fiber reinforced composites. A significant difference in values treated untreated reinforcement samples observed at a concentration 40 g/l. The composite made from regained very low content exhibited improved (tensile flexural strength). Being dual nature (hydrophilic hydrophobic groups) Hybrid fibers corresponding composites showed better as...
In this study, the different proportion of conductive component blended with polypropylene yarn were taken for making textile samples analysis electromagnetic shielding effectiveness, fabric bending moment and air permeability.
