Especially in the hot summer months, t-shirts are a must have! But the imprint is what makes them a genuine eye-catcher. Infrared emitters help to dry these imprints fast and energy efficient.
Lots of motives are applied as screen print inks on textile and need to be dried afterwards.
Calmatech BV is a globally-acknowledged manufacturer of flash cure dryers and tunnel dryers for the textiles industry, with over 20 years experience of drying and heating technology. The company strives to incorporate the latest technologies in infrared and electronics to improve the efficiency and effectiveness of its dryers. A recent development saw it replace halogen infrared lamps with medium wave carbon infrared emitters from Heraeus.
The medium wavelength is optimally suited for surface drying, as this wavelength closely matches the absorption characteristics of water. By contrast, the short wavelength of halogen lamps is more penetrative so that energy is lost as it penetrates the ink and the textile itself.
The new emitters are fitted precisely in the dryers to create an even heat distribution over the target textile surface. Calmatech BV was able du reduce the drying time from seven to eight seconds, down to two to three seconds, by using Heraeus carbon infrared emitters.
This is a great benefit for the customers, since they do not only get reduced drying time but also reduced energy costs. This is due to the fact that carbon infrared emitters have a very short response time. Different to halogen emitters which need to be switched on permanently, they are suitable for pulse operation, by being switched on only when required.
Extensive research has shown that a Carbon infrared emitter requires up to 30% less energy than a conventional short wave emitter to carry out the same drying process.
