“…The concept of smart textiles has gained considerable momentum over the last decade [5][6][7][8][9][10][11], and the implementation of such textiles in the form of fibers, yarns or fabrics containing conductive elements is crucial in a wide range of applications such as telecommunications, medical monitoring and therapy, electromagnetic shielding, electro-thermal device, and aesthetic design. Recently, the development of conductive fabrics that provide environmental and health care protection 2 of 16 from EM waves has entered mainstream consciousness [12]. They can be extensively used in radar and thermal camouflage in military, civilian, and other fields.…”

“…For example, Lin et al successfully prepared electromagnetic shielding/far-infrared elastic warp-knitted fabrics by using PET filament and rubber threads as warps and charcoal/stainless steel wrap yarns as wefts. The fabrics displayed reasonable electromagnetic shielding efficiency at lower frequency range up to 3 GHz and super elastic response rates following five cycles of stretch with 50% preset elongation [12]. The EMSE values of these fabrics following test cycles and single continuous elongations were not taken into account.…”

Multifunctional Stretchable Conductive Woven Fabric Containing Metal Wire with Durable Structural Stability and Electromagnetic Shielding in the X-Band

Elastomeric, conductive composite yarns have recently received attention around the opportunity for them to offer special protective fields. A straightforward approach for fabricating tri-component elastic-conductive composite yarns (t-ECCYs) containing stainless steel wire (SSW) was proposed previously. This work mainly focuses on the electromagnetic shielding effectiveness (EMSE) of weft-stretchable woven fabric containing t-ECCY over the X-band under different testing conditions, e.g., single step-by-step elongation, cyclic stretch and lamination events. Results showed that a woven cotton fabric with weft yarn of t-ECCY not only exhibited superior weft stretch-ability to a higher elongation (>40%) compared with a pure cotton control but also had an acceptable 15-cyclic stability with 80% shape recovery retention. The t-ECCY weft fabric was effective in shielding electromagnetic radiation, and its EMSE was also enhanced at elevated elongations during stretch at parallel polarization of EM waves. There was also no decay in EMSE before and after the t-ECCY fabric was subject to 15 stretch cycles at extension of 20%. In addition, a 90 • by 90 • cross lamination of t-ECCY fabric remarkably improved the EMSE compared to a 0 • /90 • one. The scalable fabrication strategy and excellent EMSE seen in t-ECCY-incorporated fabrics represent a significant step forward in protective fields.

In this study, a continuous‐forming wrapping process simultaneously feeds far‐infrared ray polyester (FIR‐PET) filaments and stainless steel (SS) wire to prepare functional SS/FIR‐PET composite wrapped yarns. The wrapped yarns are made into functional SS/FIR‐PET composite woven fabrics. The cover factor, tensile properties, electromagnetic shielding effectiveness (EMSE), FIR emissivity, and air permeability of the wrapped yarns and woven fabrics are evaluated, examining the influences of the combinations of diameter of SS wires (0.05 and 0.08 mm are referred as 005SS and 008SS) and wrapped count (7, 10, and 13, turns/cm). For SS/FIR‐PET composite wrapped yarns, 005SS‐7 (0.05‐mm SS with wrapped counts 7 turns/ cm) and 008SS‐7 (SS/ FIR‐PET composite wrapped yarns with 0.08‐mm SS and wrapped counts 7 turns/ cm) have the optimal tensile strength and tenacity, while 008SS‐13 has the optimal elongation and work of rupture. For SS/ FIR‐PET composite woven fabrics, 008SS‐W (W regarded as woven fabric) has the optimal tensile properties; 008SS‐W‐10 has the maximum stress at break of 27.01 MPa along the weft direction; and 008SS‐W‐13 has the maximum elongation at break of 29.83% along the weft direction. The EMSE test results confirm that changing the number of lamination layers and changing the lamination angles have a positive influence on the EMSE of the woven fabrics. The EMSE of 008SS‐W reaches −40 dB when the number of lamination layers is 3 and the lamination angle is 90°. Moreover, the EMSE of 008SS‐W reaches 0.85 when the number of lamination layers is 3. It is expected to apply functional SS/FIR‐PET woven fabric in practical domains, which that can be regarded as the middle layer of laminated composite fabric or health‐care textile. The functional SS/FIR‐PET woven fabric can give traditional laminated composite fabric with the electromagnetic‐shielding ability and FIR emissivity, and thus highly enhance the additional value of traditional composite fabrics.

This study aims to produce sandwich-structured composite boards with flame retardance, far-infrared emissivity, and electromagnetic shielding effectiveness using nonwoven, weaving processes, and heat treatment. Needle punching and roller-type hot pressing are used to improve their tensile strength, tensile elongation, puncture strength, and burst strength. The limiting oxygen index is 30 regardless of whether the flame retardance/far-infrared emissivity/electromagnetic shielding effectiveness composite board is stainless steel (SS), SS+Ni–Cu (nickel-coated copper), or SS+Ni–Cu+Cu (copper) composite fabrics. SS+Ni–Cu and SS+Ni–Cu+Cu composite boards both have optimal thermal conductivity at the eighth test hour. SS–B composite board exhibit far-infrared emissivity of 0.81; moreover, they have optimal electromagnetic shielding effectiveness of −41dB at 2450 MHz when they are laminated into three layers at a 90° lamination.
