When it comes to DTF (Direct to Film) printing, DTF adhesive powder stands out as the go-to printable adhesive. Designed to transfer graphics to materials like cotton and leather, it's a polyurethane resin-based hot melt adhesive. Before initiating the print, this powder is layered on. Its adaptability is unmatched, fitting all DTF printers and PET films. Its diverse range of qualities complement other DTF essentials such as inks and films.
What is DTF Powder Made of?
DTF powder is made of polyester resin, colors, and other additives. It is a hot melt powder made of polyurethane resin and ground into adhesive powder. White DTF powder is made of 100% high-purity polyurethane. It's a premium medium adhesive powder you can apply after printing a DTF design. DTF PreTreat Powder is a proprietary DTFPRO branded, specially formulated Thermoplastic Polyurethane (TPU) Hot Melt Adhesive Powder.
What are the Types of DTF Powders?
TPU (Thermoplastic Polyurethane) is a type of hot melt adhesive powder that is used in DTF (Direct to Film) printing. In the context of DTF, TPU is commonly used as the base material for DTF powders. When applied to printed films, it helps the ink adhere to the fabric while providing elasticity and durability to the printed design. This ensures that the printed design doesn't crack easily and can stretch with the fabric. TPU-based powders are popular because of their flexibility, which allows printed designs to move and stretch with the fabric. They also provide a soft hand feel, making the printed area comfortable against the skin.
PES powders are also used in DTF printing. When applied over printed films, they help to bind the ink to the fabric. PES offers a more rigid finish compared to TPU, making it suitable for certain applications that demand higher durability but might compromise a bit on elasticity. Polyester powders are known for their durability. They are less elastic compared to TPU, but they offer excellent wash resistance and longevity. For designs or garments where maximum durability is crucial, PES powders might be preferred.
Polyamides, often referred to as nylon, are synthetic polymers that have a wide range of applications due to their strength, flexibility, and resistance to wear. PA powders in DTF provide a balance between elasticity and durability. They help in ensuring that the printed design adheres well to the fabric while also offering a good degree of stretchability. PA powders are versatile, offering a good balance between the elasticity of TPU and the rigidity of PES. This makes them suitable for a variety of applications, depending on the desired finish and properties of the printed design.
