Strengthening the fight against Covid-19, ACTife has produced textile materials which kill bacteria and viruses. These utilise semiconductor sputtering technology, which uses silver, copper and titanium sputtering to produce hydroxyl radicals on the surface of the fabric. Hydroxyl radicals destroy viruses and bacteria by making their proteins lose function.Therefore, the materials developed by ACTife can not only block viruses and bacteria, but also use hydroxyl radicals to prevent contact with bacteria and viruses while they are adsorbed on the surface of the fabric. This technology has been verified by the SGS, Boken, Intertek, and Japan SEK to effectively sterilise 99.9 per cent of bacteria and germs.This technology generates free radicals which cause the side chains of amino acids on the surface make proteins lose their function, thereby making germs harmless and greatly reducing the risk of infection. Not only can it apply to masks, but anything that uses fabric like towels, socks, clothing or air filters. The advantage of physical antibacterial properties is that it makes the material more durable and does not precipitate any toxic or undesirable substances. As of now, the most used antibacterial chemical is bleach and the substance of bleach is actually a high concentration of sodium hypochlorite, which is well known for killing germs but it is harmful to the human body and the environment in terms of smell and touch.
