Sulfonated melamine-formaldehyde (SMF) resin was successfully synthesized with a mixture of formaldehyde, melamine, and NaHSO 3 in an aqueous solution. Then the SMF was used as the blowing agent to combine with chitosan and phytic acid for fabricating the intumescent flame retardant coating on the surface of the cotton fabric by layer-by-layer (LbL) self-assembled technology. As characterized by X-ray photoelectron spectroscopy, scanning electron microscopy, and attenuated total reflection Fourier transform infrared spectroscopy, the (chitosan/SMF 1 phytic acid) n coating was successfully deposited on the surfaces of cotton fibers. Thermogravimetric analysis results exhibited that the thermal stabilities of coated cotton fabrics under nitrogen and air atmosphere were enhanced at temperatures ranging from 400 to 700 8C compared with pure cotton fabric. At 700 8C, the char residues of cotton-5BL and cotton-10BL under a nitrogen atmosphere were improved 25.9 and 32 wt % than that of pure cotton fabric, respectively. In the vertical flame test, the self-extinguishing could be obtained for the cotton-10BL sample. This work first utilized SMF as negative polyelectrolyte to fabricate intumescent flame retardant coating by LbL self-assembled technology on cotton fabric to strengthen its thermal stability and flame resistance.

“…However, the use of fluorocarbon and partially fluorinated alkyl compounds is undesirable due to the potential risks of the degradation by-products to human health and the environment, exceptionally high greenhouse effect compared to CO 2 [24,25]. Many researchers' industrialized nanocoatings, like ZnO 2 , Cu, TiO 2 , DLC, etc., on the fabrics to increase the hydrophobic properties are still under active research [26][27][28][29][30][31][32].…”

In this work, we study the hydrophobic properties of silk fabrics by deposition of plasma-polymerized (pp) hexamethyldisiloxane (HMDSO) using low-pressure plasma-enhanced chemical vapor deposition. Recently, hydrophobic properties are under active research in textile industry. The effects of coating time and power on the HMDSO-coated silk fabrics are investigated. Water contact angle of pp-HMDSO-coated silk fabric surface is measured as a function of power and coating time. Fabric surface shows an enhancement in hydrophobicity after coating. Attenuated total reflectance-Fourier transform infrared spectroscopy reveals the surface chemistry, and scanning electron microscopy shows the surface morphology of the uncoated and HMDSO-coated fabrics, respectively. In the case of uncoated fabric, water droplet absorbs swiftly, whereas in the case of HMDSO-coated fabric, water droplet remains on the fabric surface with a maximum contact angle of 140[Formula: see text]. The HMDSO-deposited silk surface is found to be durable after detergent washing. Common stains such as ink, tea, milk, turmeric and orange juice are tested on the surface of both fabrics. In HMDSO-coated fabrics, all the stains are bedded like ball droplet. In order to study the self-cleaning property, the fabric is tilted to 45[Formula: see text] angle; stain droplets easily roll off from the fabric.

“…On a note on new revolution, textile fabrics are widely used in the various multifunctional applications in textile industry like e-textile, [21] digital printing on fabrics with coloring [22,23] with overall high performance properties like UV production, antibacterial activity, flame retardancy, water repellent, electrical, optical and electromagnetic interference shielding. [24][25][26][27][28][29][30][31][32][33][34] This review article highlights the state-ofthe-art research related to development of smart textile for EMI shielding application using ICPs, their blends and coating nanoparticles or nanofibers on the fabric (see Figure 1 which schematically illustrates as to how smart textiles can protect us from EM radiations).…”

The conductive fabrics are widely used in smart protective textile, specifically to shield millimeter wavelength radiations. In this context, intrinsically conducting polymers (ICPs) have gained enormous interest in the recent past due to their myriad applications in the field of textile specifically because of their tunable conductivity, lightweight, ease of coating etc. Numerous research studies have been focused to develop electromagnetic (EM) shielding fabric using ICPs and various functional conducting, magnetic and dielectric nanoparticles. The objective of this review article is to highlight the state‐of‐the‐art literature and recent developments in this field involving surface modification of textile fabrics using physical/chemical methods targeted towards EM shielding application. Furthermore, this review also provides useful insight in the shielding mechanism and diverse processes to design and develop smart EM shielded flexible fabrics as protective textiles.
