As a general rule, the dense molecular structure of all nylon 6,6 will prevent some spills and stains from setting into the carpet. But today's environments demand even more and Solutia delivers. Ultron nylon 6,6 with 3M Commercial Carpet Protector, or equivalent, features powerful soil protection, a heavy denier and a unique mix of cross-sections to prevent soil from becoming trapped in the carpet. The "Classic Luster" of Ultron fiber also helps to mask soiling. When resistance to acid type stains (such as Kool-Aid or wine) is required, specify Ultron Solution-Dyed nylon, which features a stain resistant polymer.
