The Rubbermaid Trapper dust mop has a blend of post-industrial 4-ply cotton and synthetic fibers for better launderability, durability, and dust retention than traditional cotton dust mops, and is made with looped ends that resist fraying and withstand laundering better than cut ends. This mop head is pretreated with a mineral oil-based mop treatment to improve dust attraction and retention. The pretreatment has a lemon fragrance, and lasts for one to three months depending on use conditions. It has a slip-on style synthetic backing sleeve that fits a dust mop frame (sold separately) without requiring strings. This mop is suitable for commercial and industrial applications. Dust mops (also called dry mops) consist of a mop head, a mop frame, and a handle. A mop head is sometimes tied on to a mop frame with connected strings, or it has a sleeve that the frame fits into. The frame provides support for the shape of the mop head, which consists of dust-collecting yarns and a flexible backing to hold the yarns together and connect to the frame. Dust mop heads have traditionally been made of cotton, and used with an oil- or water-based chemical treatment to improve dust retention. Synthetic fibers build a positive electrostatic charge from friction that attracts and retains dust so that no treatment is needed. Also, synthetic fibers withstand laundering better and dry faster, which leads to a longer product lifespan when synthetics are blended with cotton because harmful bacteria grow in a damp mop. The handle is a separate item that connects to the frame. Often either the frame or the handle also includes a swivel joint for flexible maneuverability. Rubbermaid manufactures cleaning, organizing, and material handling products for commercial, medical, and industrial applications. The company, founded in 1933, is headquartered in Huntersville, NC.
