effect of fabric electron radiation on increasing the antibacterial coating and perfume longevity

In this paper, we studied the effect of electron beam irradiation on the fabric to increase longevity of antibacterial coating and perfume release and measure it using the optical properties of the fabric. in other words, instead of using chemical compounds in the antibacterial coating and perfume structure, the change in the structural properties of the fabric as a substrate of antibacterial coating and perfume was examined. three different types of fabrics, including fabric with polyester and cotton, fabric with felt and flannelette, and fabric with flannelette and cotton floss were irradiated at different doses without alcohol and in the presence of alcohol (96% ethanol) at an energy of 10 mev with an electron beam of the rhodotron accelerator tt200. then, these three types of fabrics were impregnated with antibacterial coating and perfume after washing with cold water. finally, the longevity of antibacterial coating and perfume on them was measured by using the particle density reflection parameters and he-ne laser with a wavelength of 632 nm and a power of 5 mw. experimental results showed that electron beam irradiation of the fabric in the presence of alcohol enhanced this property.
