Compressed fleece wadding refers to a type of material that is made from compressed layers of polyester fibers. It is commonly used as a filling or padding material in various applications, such as quilting, upholstery, and bedding. The compression process involves compacting the fibers together, creating a dense and uniform wadding that provides insulation, cushioning, and warmth. Compressed fleece wadding is known for its softness, lightweight nature, and ability to retain heat.
