ABSTRACT = {Traditionally, silkworm silk has been used to make high-quality textiles. Nevertheless, various wastes from silkworm silk textiles that are no longer used are increasing, which is also causing considerable waste and contamination. This issue is causing widespread concern in countries that use more silk. Regenerated silk fibroin (RSF)
fibers have been shown to be fragile and tender, which prohibits RSF from being widely used as a structural component. Therefore, enriching the function of silk and enhancing the RSF mechanical properties are important
directions to expand the comprehensive utilization of silk products. In the present research, wet spinning was
used to create a series of RSF/tungsten disulfide (WS<sub>2</sub>) nanoparticles (NPs) hybrid fiber having distinct WS<sub>2</sub>
nanoparticles concentrations. It was discovered that the temperature of hybrid fibers containing 0.8 wt% RSF/WS<sub>2</sub>
nanoparticles might climb from 20.4°C to 85.6°C in 1 min and 108.3°C in 10 min after being exposed to simulated
sunlight for a period of one minute and ten minutes. It also had certain antibacterial activity and thermal stability.
Fabrics created by hand mixing had outstanding photothermal characteristics under natural sunlight. Furthermore, adding WS<sub>2</sub> nanoparticles might increase the tensile properties of hybrid fibers, which could be caused by
the reality that the blending of WS<sub>2</sub> nanoparticles inhibited the self-assembly of β-sheets in RSF reaction mixture
in a dosage-dependent way, as evidenced by the fact that RSF/WS<sub>2</sub> nanoparticles hybrid fibers had lesser β-sheets
material, crystalline nature, and crystalline size. The above performance makes the RSF/WS<sub>2</sub> nanoparticles hybrid
fibers promising candidates for application in photothermal fabrics as well as military clothing.},
