Properly bonded fabric can determine the difference between a great project or a wasted mess. Fabric is bonded using an adhesive substance and heat to permanently set the bond. Bonding is used to decorate sewing projects, create unique fashion looks and create special types of fabric, including Kevlar. Different fabrics require different heat settings and, depending on the application the final fabric will be used for, specific types of bonding agents. Bonding agents are also known as adhesives.
Lay the bottom layer of fabric on a flat surface, and smooth out any wrinkles.
Place bonding powder or liquid onto the fabric along the areas that will be bonded. The bonding agent can be placed using a stencil to make a pattern, around the edges for a full bond or anywhere on the fabric that will enable you to receive the desired result.
Remove any plastic stencils that you used to apply the bonding agent. Lift the stencil from two sides, and pull straight up to avoid displacing any of the bonding agent.
Place the fusible web on top of the bonding agent.
Iron on the highest setting applicable to the type of fabric you are sewing. To avoid damaging the fabric, do not set the iron higher than the recommendations on the fabric tag or bolt. Only cotton and wool can withstand the highest iron settings; other fabrics will burn.
Let the fabric and bonding agent cool, and then remove the fusible web carefully.
Place the material to be bonded on top of the original fabric.
Place a layer of parchment paper on top of the material.
Iron slowly and gently over the entire area.
Allow the project to cool, and then remove the parchment paper.
- Fabric bonding agent, powder or liquid
- Fusible web
- Baking parchment paper
Bonding agents will stiffen the fabric slightly. Not all fabric glues will form a true bond of the fabrics; some are only meant for hemming seams or temporary adhesion. Special fabrics, such as Kevlar, require a heat bonding press and special fabric weaves and are typically only made commercially.
