Infrared Emitters Optimise Technical Textiles
Infrared Heat for Modern Materials
During their manufacture, technical textiles require various heating processes - and often infrared emitters help these processes to be carried out efficiently.
Heraeus Noblelight is showing infrared emitters for the textiles sector on Stand B43 in Hall 3 at the Techtextil Exhibition, which takes place in Frankfurt from 24 to 26 May.
Infrared radiation is a reliable and established heat source in textiles processing, as infrared generates the heat directly in the material without any intermediate medium. As a result, large amounts of energy can be transferred very quickly and this helps to reduce energy costs, increase production speeds and minimise production costs.
Quartz glass infrared emitters and ceramic and metal emitters often have significant advantages over conventional heating methods such as steam or warm air, as they can be precisely matched to the product and process in terms of wavelength, shape and power.
A custom-built infrared system from Heraeus Noblelight is helping the British company Century Dyeing to carry out a drying process within a very short time window and very tight space constraints.
Century Dyeing, part of the Allied Textiles Group, is one of the UK's leading commission dyeing companies. The company works with high value synthetic fabrics to produce finished products such as parachutes, tents and hot air balloons.
On changing from dark colours to lighter shades, the dyes were not dried sufficiently on the material causing smearing. Fast response, medium wave infrared emitters proved the remedy, as they could dry the water-based dyes much more quickly because of their precisely matched, medium wavelength radiation. At the same time, these emitters react to control within seconds. This enables rapid temperature changes and, in the case of unanticipated line stoppage, the emitters are quickly switched off, minimising any damage to the material.
Infrared emitters also offer significant advantages because of their compact design and construction. Existing drying sections, such as Stenters, can be complemented and throughput increased by infrared emitters.
The demands of processing continue to increase and it is important that heating processes do not limit production. Contact-free infrared systems, with their fast heat transfer, offer especially efficient possibilities for preheating, smoothing, laminating, embossing, fixing or drying technical textiles.
Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China and Australia, is one of the technology- and market-leaders in the production of specialist light sources.
