How many times we thought that it is the worst day in our life, when we suddenly poured red wine on the new white shirt or dress? These stains are so hard to clean, and if your clothing is sensitive to detergents, only dry-cleaning will help. However, as the technologies develop, we can see that many problems that troubled generations before are solved. Today, the nanoparticles can help us do all the small or dirty work - and stain removing is one of them!Scientists from Organic Chemistry at the Faculty of Science of Monash University had made a very interesting and useful invention - a nanoparticle coating that removes most types of stains from fabric each time you spoil it! To become "self-cleaning", fabric must be prepared with a nanoparticle coating composed from anatase titanium dioxide - substance that is known to destroy stains, dirt and harmful microorganisms when exposed to sunlight.
One of the experiments, done in the lab, was pouring red wine on a white fabric, both on coated one and on usual unprepared one. Uncoated fabric was deeply stained after 20 hours, but coated exemplar showed almost no signs of red stain - without any actions from human side! All job is done by nanoparticles that work quietly but thoroughly.
No research can be done without problems, and one of the main challenges that scientists faced was how to bind the keratin to the titanium dioxide. It is hard to apply a ceramic inorganic material to organic fibers, such as wool, silk or hemp. Scientists admit it, but say that this limitation will be cleared soon.
The best part of it is that this coating does not alter the fabrics texture and feel, so a silk tie would still feel silky. It can be permanently bonded to fiber and will remain even after a harsh washing. So once coated shirt will be self-cleaning as long as you wear it.
This invention will be a blessing for all homemakers and moms whose children manage to get dirty after being left alone for a mere five minutes. If this concept gets mass-produced, we will no longer need detergents anymore! Moreover, no washing machines either.
