What is a piece of lint free or fluff free fabric with unstitched edges?

A piece of lint-free or fluff-free fabric with unstitched edges is typically known as a "non-woven fabric" or "non-woven material." These fabrics are designed to minimize the shedding of fibers, making them ideal for applications like cleaning, medical uses, or craft projects where clean edges are needed. They often come in sheets and can be made from various materials, such as polypropylene or polyester. The absence of stitched edges allows for easy handling and minimizes the risk of fraying.
