Static control is another major performance factor, especially in offices and other locations where computers and expensive electronic equipment can be damaged by electric shock. Although some contract carpet features topical anti-static treatments, independent tests show that they can be literally washed away after several cleanings. The best way you can prevent static is to choose carpet with an integral static control system built into the yarn itself. Most integral systems use fibers with anti-static cores down the center, so just the end tops are exposed and functional. Every Ultron nylon yarn bundle, however, features special carbon filaments that run down the edge of the fiber, so more conductive filament is exposed, thus static is dissipated more efficiently.
