“…FTIR spectra of cotton fabric (M) and silica coated cotton fabric at 1, 3, 5 and 7 coating times are presented in Figure 1. In the FTIR spectra, the band appears at 3472 cm -1 is assigned to the Si-O-H group of nano SiO 2 and the band at 3390 cm -1 is attributed to the vibration of C-OH group of cotton fabric (cellulose) [18]. The band appearing at 1646 cm -1 is attributed to the fluctuation vibration of group C = O.…”

Cotton fabric was coated by silica sol at different times using dip-coating method. Nano silica coated fabrics were characterized by XRD, FTIR, SEM, EDX, TGA. From SEM result, it showed that fabric surface was coated by nanosilica particles of 20-30 nm size. Nano silica coated fabrics showed the improvement not only flame retardancy (LOI increased from 18.4 to 30.8) but also the tear strength. Tear strength increased from 23 N/mm (cotton fabric) to 29.9 N/mm (fabric coated nanosilica at 3 times).

“…The peaks that refer to C─N─H (1537 cm À1 ), C─N (1465 cm À1 ), ─OH (3291 cm À1 ), and C─O (1032 cm À1 ) in the AuNWs-impregnated cotton fabric present the hydrogen bonding between ─NH (1527 and 1465 cm À1 ) of AuNWs and ─OH (3284 and 1037 cm À1 ) of cotton fabric. [45][46][47][48] The interdigitated electrode arrays were embroidered using conductive copper-doped fibers (Figure S5, Supporting Information). The sensing mechanism is attributed to the piezoresistive behavior correlated with the pressing force-dependent touch between AuNWs-impregnated fabric and the embroidered electrode arrays.…”

According to the sensing mechanism, pressure sensors can be divided into five types: piezoelectric, [1,2] piezoelectric resistivity, [3][4][5][6] capacitance, [7,8] triboelectric, [9,10] and transistor. [11] Piezoresistive sensors have attracted much attention in recent years due to their simple design, low manufacturing cost, good signal repeatability, low power consumption, low working voltage, and simple measurement scheme. [12][13][14][15][16][17][18] The elastic pressure sensor is usually composed of sensing material, substrate material, and electrode. The sensing material can be filled or coated on the substrate material to activate the conductive path. Under the external pressure, the contact area between the surface conductive elements increases significantly, resulting in a significant decrease in the path resistance or contact resistance. The change of resistance is due to the deformation of the microstructure under pressure, which leads to the change of the contact area. The traditional rigid material pressure sensor has been eliminated due to its poor reliability and low applicability. As an optional piezoresistive material, nanomaterials have been proved to be potential components of novel strain sensors with enhanced performance. High-performance sensor devices based on several typical nanostructures, such as carbon nanotubes [19,20] and graphene, have been developed. [21] However, the sensors based on these materials have some defects, such as complex manufacturing processes and unknown toxicity.Sensing material is the essential component of a pressure sensor. In terms of sensing materials, metal nanomaterials, as one of the most popular multifunctional conductive materials, have been widely used in chemistry, biomedical, optical, and other fields. [22] Specifically, gold nanowires (AuNWs) are a flexible filamentous structure in the nanoscale and behave like polymer chains because of their ultrathin nature (2 nm in width and >10 000 in aspect ratio). [23] AuNWs have the advantages of high chemical inertness, good biocompatibility, wide electrochemical window, high conductivity, and easy surface modification that depends on thiol gold chemistry. Zhang and co-workers reported a pulse monitoring sensor based on AuNWs and polyacrylamide

At present, nanotechnology is a priority in research in several nations due to its massive capability and financial impact. However, due to the uncertainties and abnormalities in shape, size, and chemical compositions, the existence of certain nanomaterials may lead to dangerous effects on the human health and environment. The present review includes the different advanced applications of nanomaterials in textiles industries, as well as their associated environmental and health risks. The four main textile industry fields using nanomaterials, nanofinishing, nanocoatings, nanofibers, and nanocomposites, are analyzed. Different functional textiles with nanomaterials are also briefly reviewed. Most textile materials are in direct and prolonged contact with our skin. Hence, the influence of carcinogenic and toxic substances that are available in textiles must be comprehensively examined. Proper recognition of the conceivable benefits and accidental hazards of nanomaterials to our surroundings is significant for pursuing its development in the forthcoming years. The conclusions of the current paper are anticipated to increase awareness on the possible influence of nanomaterial-containing textile wastes and the significance of better regulations in regards to the ultimate disposal of these wastes.
