JCC Releases High-Elastic TPU Hot Melt DTF Powder for Heat Transfer Printing
Tianyang New Materials (JCC), a hot melt adhesive manufacturer operating since 2002 with plants in Nantong, has introduced a new generation of thermoplastic polyurethane (TPU) hot melt powder engineered specifically for direct-to-film (DTF) printing and heat transfer decoration. The product is supplied as a free-flowing powder with a tightly controlled 80-170 micron particle distribution, giving transfer printers a soft hand feel, high colour yield and dependable wash durability on cotton, polyester, blends and nylon.
Digital textile printing has moved from a sampling tool to a mainstream production tool within a few years. That shift has exposed a weak link in many print shops: the transfer powder. Conventional copolyamide powders bond well on rigid fabrics, but they stiffen stretch knits and can fail after repeated home laundering. TPU chemistry solves both problems at once, because the adhesive film formed during pressing remains elastic and recovers with the fabric instead of cracking.
Why TPU Instead of Conventional Copolyamide Powder
- Superior elasticity: the bonded layer stretches with the garment, so prints on sportswear, leggings, swimwear and stretch denim resist crazing and edge lift.
- Low activation temperature: full bonding is reached at 110-130 degrees Celsius, which protects heat-sensitive synthetics and reduces energy consumption.
- Excellent laundry resistance: passes 40 degrees Celsius home wash cycles and repeated industrial washing without delamination or colour bleed.
- Soft hand feel: the fine particle size builds a thin, even glue line, so the print does not feel like a rigid plastic panel.
- Clean and compliant: 100 percent solid content, no solvent, no VOC emission, REACH and RoHS compliant and suitable for OEKO-TEX certified supply chains.

Supply, Packaging and Technical Support
The powder is produced on a dedicated milling line with in-line sieving, so every batch is verified for particle distribution, melting point and flow behaviour before packing. Standard packs are 20 kg moisture-barrier bags, and OEM labelling, custom particle cuts and matched melting points are available for volume accounts. Typical lead time is 7-15 days from order confirmation, with T/T, L/C and D/P payment terms accepted.
JCC technical teams support customers with press parameter trials, wash test protocols and troubleshooting on new fabric and film combinations. Free samples of 1-2 kg are available for print shops that want to benchmark the powder against their current supplier before committing to a production order.
