Fusible interfacing, a fabric component with a heat-activated adhesive on one side, is employed to add structure, stability, or support to various textiles. Application involves fusing the interfacing to the designated fabric using an iron, creating a unified layer. For example, it is commonly used to stiffen collars, cuffs, and plackets in garment construction, or to provide reinforcement to bags and other accessories.
The utilization of this material enhances the durability and appearance of finished items. By adding body and preventing stretching or distortion, it contributes to a more professional and long-lasting result. Historically, interfacing was sewn in place, a more time-consuming process. The advent of the fusible variety streamlined garment construction, offering a faster and more efficient method for achieving desired structural enhancements.
