Strain Sensors Based on Electroless Ni-P Plated Polyester Woven Fabrics
Mostafa Youssefi,Elaheh Fanaei,Mohsen Shanbeh 한국섬유공학회 2019 Fibers and polymers Vol.20 No.3
In this study, polyester and polyester/spandex woven fabrics were electroless Ni-P plated at different conditions. The physical and electrical properties of Ni-P coated fabrics were investigated by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), wide angle X-ray scattering (WAXS), tensile tests, and air permeability, hydrophobicity and cyclic electro-mechanical measurements (strain sensor evaluation). SEM, WAXS and EDX results revealed the existence of an amorphous layer consisting of Ni and phosphorous atoms on the surface of the fabrics. Besides, the coated fabrics became more hydrophobic than the raw fabrics and the air permeability of them was also decreased. The electroless plated polyester fabrics showed some regular variation of resistance versus time during cyclic loading under 25 % strain, with very distinct maximums and minimums in the resistance/time curves. This trend was not observed for polyester/ spandex coated fabrics due to its mechanism of deformation under strain. As a conclusion, the polyester Ni-P electroless plated fabrics could be considered as strain fabric sensors that might be applied in smart textiles.

This paper describes a study on the development of novel lightweight and highly flexible composites forelectromagnetic interference (EMI) shielding applications. The weft-knitted fabrics produced by using polyester/cotton,polyester/cotton-copper, and polyester/cotton-stainless steel composite yarns with metal deposition and without metaldeposition were tested to determine the EMI shielding effectiveness (SE). The surface structures of all composite fabricsamples were observed by stereomicroscope. The state of the presence of metal particles on the metal deposited compositefabric was studied by field emission scanning electron microscope (FESEM) and energy dispersive X-ray (EDX) analyzer. The EDX analyses confirmed the presence of metal particles, and the FESEM analyses revealed uniformly deposited metalparticles on the surface of composite fabrics. The EMI shielding was also evaluated using vector network analyzers in thefrequency range of 8-12 GHz for all samples. The highest value of EMI SE in this research for the composite fabric with themetal deposited sample was achieved to 19.53-23.95 dB. Moreover, the breathability and the durability of produced fabricswere characterized by air permeability, moisture regains, abrasion resistance, and washing fastness. The results of EMIshielding, durability, and breathability tests confirmed their potential for use as an excellent material for EMI shielding inwearable textiles for commercial applications.

Suppressing the human body’s thermal radiation is important for infrared (IR) camouflage and radiative personal heating. Aluminum (Al) is a good insulator for thermal radiation, but there are challenges to its use in wearable applications. In this study, multifilament yarns containing spherical Al particles were produced by a pilot plant melt-spinning machine. The physical and mechanical properties of the produced composite fibers were measured and analyzed by the different test methods. The results showed that the presence of Al particles up to 2 wt% did not negatively affect the production process and microstructure of the fibers. However, the fabric containing 2 wt% Al particles showed a decrease in IR transmittance by 66%, compared to the control fabric. Thermal camera images confirmed the suppression of body heat radiation.
