TPU Hotmelt powder plays a crucial role in Direct to Film (DTF) printing, a relatively new and innovative method in the realm of garment decoration and textile printing. DTF printing involves transferring designs directly from a printed film to fabric using heat and pressure, and TPU Hotmelt powder is integral to this process.

What is TPU Hotmelt Powder?

TPU (Thermoplastic Polyurethane) Hotmelt powder is a finely ground thermoplastic material that melts and adheres to textiles under heat. It acts as a bonding agent between the printed film and the fabric during the transfer process. This powder is designed to activate at specific temperatures, ensuring a strong and durable bond without damaging the fabric or the printed design.

Key Features and Benefits:

1. Adhesive Properties: TPU Hotmelt powder provides excellent adhesive properties when activated by heat, creating a secure bond between the film and fabric. This ensures that the transferred design adheres firmly and uniformly to the textile surface.

2. Compatibility: It is compatible with a wide range of fabrics, including cotton, polyester, blends, and even some technical textiles. This versatility makes it suitable for various applications in apparel, accessories, and promotional items.

3. Durability: Once applied and properly cured, TPU Hotmelt powder ensures durability of the print, offering resistance to washing and abrasion. This makes it ideal for creating long-lasting designs on garments.

4. Ease of Application: The application process is straightforward. After printing the design onto a special film using compatible printers, the TPU Hotmelt powder is sprinkled over the design. Excess powder is then removed, and the film is cured with heat to activate the adhesive properties and transfer the design onto the fabric.

5. Environmental Considerations: TPU Hotmelt powder is often formulated to be environmentally friendly, containing no harmful chemicals or substances that could impact human health or the environment adversely.

Applications:

• Apparel Decoration: Used extensively for creating customized T-shirts, hoodies, caps, and other apparel items with intricate designs and vibrant colors.

• Promotional Products: Ideal for producing branded merchandise such as bags, hats, and accessories with logos or promotional messages.

• Textile Industry: Offers new possibilities for textile manufacturers and designers looking to innovate with print-on-demand capabilities and quick turnaround times.
