Two chinese Scientists have developed a method to create cotton fabrics that clean and deodorize themselves when exposed to sunlight.
Mingce Long and Deyong Wu, from the Shanghai Jiao Tong University, say their fabric uses a coating made from a compound of titanium dioxide. Their report describes “A cotton fabric coated with nanoparticles made from a compound of titanium dioxide and nitrogen“. They show that fabric, coated with the material, removes an orange dye stain when exposed to sunlight. Additional nanoparticles composed of silver and iodine accelerates the discoloration process. They also add that the coating remains intact after multiple washing and drying (although we thought the main purpose was that we wouldn’t need to do that anymore).
The two scientists note self-cleaning cotton fabrics have been made in the past, but at this time, the fabrics self-clean process worked only when exposed to ultraviolet rays. That’s why they set out to develop a new cotton fabric that cleans itself when exposed to ordinary sunlight.
Should we keep your washer as of yet?
Well, in the end, the story doesn’t tell how the fabrics looks like neither if this technology will be massively used. Maybe the real question is: are we mentally prepared to wear wardrobe that rids itself of stains and dirt when exposed to sun?
