“…The thermal stability of the fabrics was effectively assessed with thermogravimetric (TG) and derivative thermogravimetric (DTG) analyses, as shown in Figure 7a,b. In general, silk has a small mass loss in the range of 40-200 • C, mainly due to the evaporation of water; in the range of 320-480 • C, silk fabrics show a large mass loss, which is due to their thermal degradation [3]. Therefore, we concluded from the readings that the thermal degradation temperature of the untreated silk fabric was 324 • C and that of the C@SiO 2 -nanoparticletreated silk fabric was 320 • C. We noted a slight acceleration in the decomposition, possibly occurring due to the ability of C@SiO 2 nanoparticles to increase the absorption of heat by the fabric.…”

“…Therefore, they can be used as photothermal conversion materials [19], anti-UV materials [20], and electromagnetic shielding materials [17,21]. Because carbon-based nanomaterials have SP 2 and SP 3 hybrid orbitals with very close energy levels and π-electron clouds, they show excellent photothermal conversion performance and high efficiency due to their strong absorption of near-infrared light with a wide range of visible light absorption wavelengths [22,23]. Therefore, they can be used as a photothermal conversion material for wearable smart fabrics.…”

With the improvement in people’s living standards, the development and application of smart textiles are receiving increasing attention. In this study, a carbon nanosurface was successfully coated with a SiO2 layer to form C@SiO2 nanomaterials, which improved the dispersion of carbon nanomaterials in an aqueous solution and enhanced the absorption of light by the carbon nanoparticles. C@SiO2 nanoparticles were coupled on the surface of silk fabric with the silane coupling agent KH570 to form C@SiO2 nanosilk fabric. The silk fabric that was subjected to such surface modification was endowed with a special photothermal function. The results obtained with scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), and infrared spectroscopy (FTIR) showed that C@SiO2 nanoparticles were successfully modified on the surface of the silk fabric. In addition, under the irradiation of near-infrared light with a power of 20 W and a wavelength of 808 nm, the C@SiO2 nanosilk fabric experienced rapid warming from 23 °C to 60 °C within 30 s. After subjecting the functional fabric to hundreds of photothermal experiments and multiple washes, the photothermal efficiency remained largely unchanged and proved to be durable and stable. In addition, the thermogravimetric (TG) analysis results showed that the C@SiO2 nanoparticles contributed to the thermal stability of the silk fabric. The UV transmittance results indicated that C@SiO2 nanofabric is UV-resistant. The silk modification method developed in this study is low-cost, efficient, and environmentally friendly. It has some prospects for future applications in the textile industry.

“…However, silk possesses inferior ultraviolet (UV) protective behavior and cannot resist the direct attack of UV radiation, which is the primary cause of sunburn, skin tanning, and skin cancers. 6,7 Accordingly, functional modification to improve various performances of silk in terms of natural fiber applications in technical aspects has become an appealing research topic over the last decade. A few nanomaterial-based strategies were developed, for instance, silk was treated with the nanoparticles of platinum, copper sulphide, gold, and silver to produce antibacterial activity against Staphylococcus aureus ( S. aureus ) and Escherichia coli ( E. coli ).…”

Natural dyes have attained the interest of scientists over the last decade due to their functional activities in addition to their primary role of color impartation on textile materials. This study is the first report on the functionalization of silk with antimicrobial and ultraviolet protective properties using a dye extract from the roots of Rubia cordifolia L. in conjunction with chitosan as a bio-mordant. Alum mordant was also used in the dyeing process alongside chitosan for comparison purposes. Fourier transform infrared spectroscopy and ultraviolet-visible spectroscopy were utilized to determine the anthraquinone-based components of the dye extract. Furthermore, the structure and surface morphology of silk fibers before and after dyeing were investigated. The dyed silk samples exhibited good fastness against washing, rubbing, and lighting. The chitosan mordanted-dyed silk presented remarkable antimicrobial properties with maximum inhibitions of 96.71% and 99.08% against Escherichia coli and Staphylococcus aureus, respectively, and only 2.3% spore germination of white mold ( Aspergillus spp.). Likewise, an excellent ultraviolet protection factor was achieved in the chitosan modified-dyed silk. The findings of this study demonstrated the potential of the Rubia cordifolia L. extract as a functional dye, as well as the advanced properties of chitosan in increasing the fastness and functional performance for the dyed silk compared to alum mordant.

“…Generally, the ultraviolet ray is divided into three fragments by the wavelength: ultraviolet A (UVA) (315∼400 nm), ultraviolet B (UVB) (280∼315 nm) and ultraviolet C (UVC) (200∼280 nm). 21–24 In order to absorb ultraviolet rays in a full spectrum of ultraviolet rays, inorganic ultraviolet absorbers, such as titanium dioxide (TiO 2 ) nanoparticles, were added into benzotriazole coatings. As an ultraviolet blocking material, TiO 2 is attracting more and more attention because of its excellent heat resistance, nontoxicity and physiochemical stability.…”

In this work, multifunctional knitted fabrics with ultraviolet resistance and antibacterial properties are presented. The functional coating was fabricated on cotton fabric through a facile one step pad-dry process after being dipped in benzotriazole derivative and titanium dioxide mixture solution. Alkali catalyzed polymerization was applied to synthesis amino-benzotriazole, which could form covalent bonds with cellulose after fixation on cotton fiber. The coating was compacted and agglutinated to the cotton fibers, which were observed by scanning electron microscopy, the wash fastness also revealed the bonding capacity. The ultraviolet protection factor was calculated by the transmittance value, the results illustrated tremendous improvement in the ultraviolet protection factor of the functionalized knitted fabrics, since the energy absorption and surface nanoparticles scatters of incident ultraviolet radiation. Moreover, the attenuation rate of ultraviolet resistance is low. The bursting strength, pilling resistance, air permeability and moisture resistance of the functionalized knitted fabrics demonstrated their good wearing comfort properties. In addition, the as-constructed fabrics also showed a strong ability to resist Escherichia coli and Staphylococcus aureus.
