  • UV LIGHT SANITIZATION OF CARPETING
    Publication number: 20220064854
    Abstract: A healthier carpet employing UV light-transmitting threads, which facilitate UV light transmittance down from the surface of the carpet, through the interior of the carpet, and into the primary backing of the carpet. The UV light can destroy bacteria, molds, viruses, yeast, and other microorganisms, which are present in the carpet. An external UV light source, with UV wavelengths from 100-400 nm, can be passed over the carpet for effective sanitization.
