Some types of ceramics show thermally-induced photoluminescence, emitting light in the far infrared (FIR) region of the electromagnetic spectrum.
One way in which fabrics can be impregnated with ceramic is the process of electrophoretic deposition or EPD in the industry.
Next, a current is passed through and the nano ceramic particles coat and impregnate the fabric.
The process by which the textile is impregnated depends on what materials will be used, as well as the intended purpose of that fabric.
In the electronic industry, the fabrics are used primarily for insulation and seals, because of its low porosity.
