When sourcing transfer badges (such as heat transfers, TPU, or silicone patches), you must prioritize adhesion strength and color accuracy. Ensure the supplier uses high-quality hot-melt adhesives that are compatible with your specific fabric type (e.g., cotton, polyester, or nylon). Technical benchmarks should include a washing fastness rating of Level 4-5 (ISO 105-C06) and the ability to withstand at least 50 industrial laundry cycles without cracking or peeling. For high-end branding, request high-definition (HD) printing with a resolution of at least 300 DPI to ensure sharp logo edges.
