Unlike woven interlining, non-woven interlining is created by bonding or felting fibers together without weaving. It offers uniform support, smooth appearance, and good drapability. It can be attached to fabric layers through sewing, fusing, or adhesive bonding. Made from synthetic fibers like polyester, polypropylene, or nylon, non-woven interlining is strong, durable, and resistant to shrinkage. It is widely used to enhance the functionality and aesthetics of garments, providing structure while ensuring comfort and flexibility.
