Trapper Dust Mop features blended, four-ply yarn for general-purpose dusting. Made with a high percentage of recycled post-industrial cotton & 35 percent PET plastic, this mophead is pre-treated, pre-shrunk & fully launderable for long product life. Looped ends reduce de-plying & minimize linting. Mophead is easy to attach to Rubbermaid Commercial Snap-On Wire Dust Mop Frames. Envelope end-style backing allows easy frame insertion with no strings to tie or break. Heavy-duty synthetic backing resists rotting & is colorfast & absorbent.
