These microfiber dust mops are some of the most durable energy efficient dust mop products you will ever find. Our Industrial microfiber closed loop dust mop is constructed with an 80/20 blend microfiber yarn that contains loops which are twisted closed for maximum dirt and dust pick up and retention along with more durability. These closed microfiber loops along with the Industrial heat set dust mop backing make the product more durable, and more effective than other microfiber dust mops. Other microfiber dust mops container large open loops that snag and tear leaving big webs of microfiber yarns during and after processing, our closed loops eliminate this all together while providing more surface area on each strand to attract and hold dirt and dust particles. These mops fit a standard 5” wide wire dust mop frame and are available in 18”, 24”, 36”, 48”, 60”, and 72” lengths.
