Monarch Brands' SmartEdge laser-cut edge microfiber cloth is made from
80% polyester and 20% polyamide. This innovative spliced yarn creates miniature gripping "hooks" built into its yarn construction with a positive electrical charge that attracts dust and dirt, which carries a negative charge. Microfiber attracts and traps dirt like a magnet! The laser-cut edgeless construction has a zig-zag border and no new edges for streak-free cleaning.
