Innovative technical textiles for garments - Techtextil presents innovations for functional garments in the Avantex product group
New technology can absorb heat and UV radiation / New intercalated fabric offering protection against electromagnetic radiation
New sun-protection finish for textiles stops negative aspects of sunshine
To much sun ages the skin, causes sun burn or, in the worst case, melanomas. Particularly unpleased in this connection are dark colours that reflect neither the visible nor invisible rays of the sun. Schoeller Technologies AG (Switzerland) took these negative aspects as their basis when developing the Coldblack® textile finish in cooperation with the Clariant chemical company. Coldblack® technology is used to treat textiles and directly influences the absorption of heat rays through an invisible colour change. Additionally, the fabric then offers more protection against UV rays (at least UPF 30) without causing any change in the feel or look of the material. Moreover, this new textile finish is permanent, i.e., it does not loose its effect after washing, and can be used on all textiles. The product attracted great interest soon after being officially launched in August 2008. "We seem to have discovered a great demand and this is reflected by the large number of inquiries already received", reports Hans U. Kohn, Chief Operation Officer (COO) of Schoeller Technologies AG. "In the garment sector, Coldblack® is currently used in the outdoor, motorcycle, golf, cycling, swimming, running and workwear segments", adds Kohn. Coldblack ® made its market debut last December at the Davis Cup Finale in Mar del Plata, Argentina, where the line judges and ball kids were dressed completely in black by Hugo Boss. This was possible because, according to the manufacturer, heat is managed over the complete colour spectrum. Motorcyclists, whose season centres around the summer months, are frequently dressed in black. In this connection, BMW Motorcycles have taken the initiative and are using theses textiles in their Streetguard 3 suits. Having reached this point, however, the Swiss company does not intend to rest on its laurels. "Business and leisure wear will also come. Additionally, we have also carried out initial tests for seat covers and the results have been very promising. Heat management is a topic of great interest in connection with a wide variety of textiles that are subject to direct sunlight. I can also imagine that they will be suitable for use in the architecture and design fields, and I am looking forward to seeing which companies will contact us at Techtextil," says Kohn.
SR Shield against electromagnetic radiation
Electromagnetic radiation is a not-to-be underestimated danger in certain situations at work and in everyday life. At Techtextil, SR-Webatex GmbH (Germany) will present a new product called 'SR Shield', a protective textile layer that is integrated into garments in the form of an intercalated fabric. "SR Shield is designed to protect people who, for example, work on radar equipment and are thus subjected to permanent and direct high-frequency radiation", says Axel Merz, Head of Development and Sales at SR-Webatex GmbH. "Thanks to a high-tech finish, SR Shield effectively screens the wearer from electromagnetic radiation", adds Merz. According to the manufacturer, the product is distinguished by very high level of shielding effectiveness for radio frequencies in the range from ten megahertz to four gigahertz and is, therefore, highly suitable for use as a protective-clothing fabric in these sectors. The fabric sample is effective not only in the case of linear, vertical and horizontal polarisation but also against waves with circular polarisation. Figures show the extent to which SR Shield protects, i.e., how little radiation can penetrate the fabric. Thus, 99.99999 percent of the radiation is stopped in the case of a load of, for example, 70 decibels. This is confirmed by an expertise commissioned by SR-Webatex GmbH last year from the Universität der Bundeswehr Munich (University of the German Armed Forces), Department for High Frequency, Microwave and Radar Technology in Neubiberg. SR Shield could also be of interest for military applications. SR-Webatex GmbH conducted tests with infrared cameras and came to the conclusion that SR Shield has the same properties of normal camouflage fabric with infra-red resistance, which makes conceivable the development of a fabric with SR Shield for the 'invisible soldier'. A business suit with integrated protection is already reality. "The SR Shield fabric is integrated into the breast pocket of suits because this is often where mobile phones are carried. Thus, the wearer is protected against this form of electro-magnetic radiation", says Metz
How textiles can be protected
The driver of a tanker truck is liable to come into contact with oil, a railway man with lubricants, such as graphite. Protective clothing generally has a hard life, gets dirty and has to be washed time and again. Thus, textiles also need protection to ensure durability and comfort. Trans-Textil GmbH from Freilassing (Germany), which claims to be one of Europe's leading companies in the fields of lamination, coatings, printing and special finishing for functional textiles, will present four new products in accordance with the Öko Tex 100 Standard at Techtextil 2009. One of them is called Topaz dual guard, a finishing agent that protects garments and, according to the manufacturer, doubles the service life. On the one hand, the fabric thus treated is resistant to water, oil and dirt. On the other hand, contamination caused by oil or graphite can be washed out completely. Hence, Topaz dual guard can ensure that protective clothing in accordance with EN 471 remains highly visible longer and that products made in accordance with other personal protection-equipment standards continue to meet these standards longer. The company draws attention to the long service life of such products and the resulting economic efficiency of the textiles.
Topaz airtouch is another new development by the Bavarian company. In this case, the focus is on the inside of a garment because they are areas of application where the protective garment is worn directly on the skin, e.g., to save weight. Topaz airtouch is a highly breathable composite with a coating that is applied to the membrane as fine spots, which protect it against mechanical damage at the same time as making it comfortable to wear directly against the skin. In this connection, Topaz airtouch is light and environmentally friendly because it is a water-based product. Additionally, it can be used specifically in accordance with the appropriate technical circumstances. "The perfect interaction of the individual components is the special strength of Trans-Textil GmbH", explains Wilhelm Krings, General Manager of Trans-Textil GmbH. "Through our expertise in the individual technologies, we can draw on a broad portfolio of options to find the ideal solution for every requirement." Topaz functional textiles are used in the fields of protective clothing, fashions, sport and leisure, as well as medical and technical applications. According to the company, the emphasis is on protection and safety in combination with top durability and comfort.
