Dishwashing sponges are usually made of materials such as polyester, polyurethane, nylon, etc.
These materials have good water absorption and cleaning effects, and can quickly dry dishes. Among them, polyurethane sponge is widely used in dishwashing sponges due to its characteristics of insulation, heat insulation, sound absorption, shock absorption, flame retardancy, anti-static and good breathability. In addition, there are dishwashing sponges made from materials such as polyvinyl alcohol, loofah pulp, and imitation loofah pulp, each with its own characteristics. For example, polyvinyl alcohol has high water absorption capacity, while loofah pulp helps to remove oil stains due to its rough surface.
