Hot-melt powder for clothing generally refers to tpu polyurethane-based adhesives. The melting point is generally around 110 degrees Celsius. This temperature will melt the powder from particles into a gel.

1. Air humidity (reference value 40%-70%)

Air humidity mainly affects the powder sticking to the film during storage, printing, and powder shaking. There is no feedback that it has an impact on the pressing process.

Inkjet technology utilizes tiny droplets of ink to facilitate direct printing without the device coming into contact with the printing surface. Because the technology supports non-contact printing, it can be applied to a variety of media and is now being introduced into a wide range of fields from general-purpose to industrial. The simple structure combining the inkjet print head with the scanning mechanism has the advantage of reducing equipment cost. In addition, because they do not require a printing plate, inkjet printers have the advantage of saving print setup time compared to traditional printing systems (such as screen printing) that require fixed print blocks or plates, etc.

One of the most commonly raised questions from people regarding UV printer is “Do UV printer emit radiation?”Before we can answer that, lets find out a little more about radiation. In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Almost everything emits radiation of one kind or another. Like many other questions phrased similarly. You are implying that radiation is dangerous. But the scientific fact is that there are different types of radiation and not all of them is harmful. Radiation can be low level like microwaves, which is called non-ionizing and high level such as cosmic radiation, which is ionizing radiation.The harmful one is the ionizing radiation.

UV inks used in UV printers can be divided into hard ink and soft ink according to the hardness properties of the printing material. Rigid, non-bending, non-deforming materials such as glass, ceramic tile, metal plate, acrylic, wood, etc., use hard ink; elastic, bendable, twisting materials such as leather, soft film, soft PVC, etc., Use soft ink.

The relationship between the waveform of the uv printer nozzle and the uv ink is as follows: the waveforms corresponding to different inks are also different, which is mainly affected by the difference in the sound speed of the ink, the viscosity of the ink, and the density of the ink. Most of the current printheads have flexible waveforms to adapt to different inks.
