Abstract
A cleaning cloth is formed by treating a fibrous material with a composition to which solid particles adhere. The composition includes a tackifier, a pressure-sensitive adhesive and a slip agent. The tackifier is 45-77 wt. %, the pressure-sensitive adhesive is 20-40 wt. % and the slip agent is 3-15 wt. % of the composition. Other ingredients, such an antifoam agent and a pH control, can also be added. The tackifier is an unsaturated, low-molecular-weight resin having low vapor pressure and a molecular weight of<30,000, e.g., polybutene, polyisobutylene, polyhexene or an unsaturated alkyl. The preferred tackifier is polybutene. The pressure-sensitive adhesive is acrylic, styrene butadiene rubber, vinyl acetate or other suitable pressure-sensitive compounds. The slip agent is a high-melting-point wax or a natural fatty acid ester. The preferred slip agent is ammonium stearate. The cleaning cloth is formed by applying a water-based emulsion of a mixture of a tackifier, a pressure-sensitive adhesive and a slip agent to the untreated cloth. The tackifier, adhesive and slip agent form a continuous coating on the fibers of the cloth.
