DTF PES Hot-melt Powder

1. Application Introduction

In the DTF process, hot melt powder is the critical material that bonds the printed design to the fabric. It determines the transfers hand feel, elasticity, adhesion, and wash resistance. TPU and PES are the two most common types of hot melt powder, each with distinct properties suited for different fabrics and requirements，selection Guide below is for your reference.

Important Notes:

l   Match the Fabric: The primary rule is to match the powder type to the fabric composition. Use TPU for stretchy cotton/spandex, and PES for polyester/nylon. Using the wrong type can lead to poor adhesion or cracking.

l   Blending: For cotton-polyester blends, the choice between TPU or PES depends on the desired stretch and hand feel. Sometimes they are blended in specific ratios to achieve the best balance.
