3D hot‑melt adhesive powder is mainly applied for fabric 3D patterns, embossed effects and textile lamination. It can be used via powder sprinkling, screen printing and electrostatic spraying. Bonding and shaping are achieved through high‑temperature melting and cooling.

Notes
1. Store powder in cool and dry place to prevent caking. Sift caked powder before use.
2. Excessive temperature leads to collapse and flowing of 3D relief. Insufficient temperature causes incomplete melting, poor bonding strength and inferior wash resistance.
3. TPU‑based 3D hot‑melt adhesive powder is recommended for stretch fabrics to avoid cracking under tension.
4. Perform washing test only after products are fully cooled for better wash resistance and anti‑aging performance.
