Nanotechnology makes for better hair care products and textile microfibers

NanoWerk.com - Thu, 08/30/2018 - 14:29
Nanotechnology researchers now have developed a natural and non-damaging hair surface engineering technique for making hair coloring formulations that do not use any chemical reactions but instead relies only on physical forces acting at a very close range. The same surface engineering approach is applicable to textile microfiber modifications because natural textiles like like wool, silk, cellulose, but also biomimetic synthetic textiles, have similar chemical composition.
