Iron - On Backing
Iron-on backing attaches the patch to the fabric by applying heat and ironing with pressure. Usually used on denim and cotton, do not use iron-on backing patches on towels and corduroy. Also, do not use this type of backing on fabrics with a rough surface. If it is used for hats, it is better to use a hat press rather than an iron. Or the patch will be heated unevenly and cannot be firmly attached.
Note: Application methods, pressing temperatures, and times may vary depending on the product type, design, material, application surface, and equipment used.
