24 S T A R T H E R E 2 0 2 1 may not need to have as long of a dwell time, which in some cases reduces possible damage to the garment or the emblem. Preheating can also release retained moisture, fabric softeners, or other finishes that might interfere with a good bond. If the garment happens to be wrinkled, it ensures a nice flat surface for the patch. Three seconds is usually enough to accomplish all of these goals. A common mistake is to test a newly applied emblem by tugging on it before the adhesive has had enough time to cool. Be sure to wait until it is cool to the touch before trying to lift it to test the bond. Also be aware that on patches with a thick merrowed edge, the heat-seal adhesive does not extend over this border. Only the flat body of the patch has heat-seal adhesive on it. This is sufficient to securely hold the patch onto a garment, but the border will not also be glued down. Finally, you should always follow your supplier's instructions for temperature, time, and pressure; however, there are often factors like humidity and shop temperature that can impact these recom- mendations. The type of fabric and press you use also can require slight adjustments. For the best outcome, test following the recom- mendations and then adjust accordingly based on the results. Know Your Options for Emblem Creation: From pre-decorated patches and kits to creating them from scratch, get to know your emblem options at For jobs requiring heat-sensitive fabrics, a low-melt adhesive is the best choice. This type is ideal for polyester, rayon, and silk. When in doubt, always do a test print and evaluate the results. An industrial melt adhesive is ideal for heat sealing emblems that will be subjected to commercial laundering or any activity that will involve a lot of wear and tear. It offers a stronger bond and longer durability than any other type of adhesive. With patches that have a thick merrowed edge, the heat-seal adhesive does not extend over this border. Do not be alarmed when the edges are not sealed. If properly applied, the emblem will still maintain a secure bond for the life of the garment. One of the most common mistakes is to test the heat- sealed bond before it has completely cooled. If it is still hot or warm, you may be able to peel it off. Wait a sufficient amount of time before testing. A handy accessory for applying heat-seal emblems is thermal tape. It can be applied prior to pressing to ensure the patch stays in place. If you are not using a pad or a pillow, always cover the decoration with a piece of kraft paper or a silicone sheet before heat pressing. This protects the emblem from scorching and keeps excess adhesive from sticking to the upper platen.
