This is produced with an 80/20 split fiber microfiber yarn blend and polypropylene strips for additional abrasion. These pads are 19” x 5 ½” in size and are designed to be used with our 16” Aluminum microfiber frame with overhang on each end after shrinkage. This pad is designed with a combination of plush cut-pile microfiber for good surface friction and absorption & polypropylene stripes to increase scrubbing and reduce drag or fatigue to the user. The center of the pad is made with a layer of microfiber fabric rather then a sponge which will increase the overall absorption of the pad while reducing the potential for bacteria that you find with sponges. These pads work great where color coding cleaning systems are in place and can be used for both wet mopping and dry mopping.
