Researching tomorrow's innovative textiles
Although textiles have a tradition extendng back thousands of years into antiquity, there still remains room for innovation today, and the aim of this year's Fiber Society conference was to sound out the opportunities on offer in this regard. The society was founded in 1941 to encourage and support scientific progress in the field of fibers and fiber products, and the conference motto, "Fiber Research for Tomorrow's Applications", was therefore entirely appropriate. The aim is to emphasize the message that "Textiles have an unbroken potential," as Rudolf Hufenus, of Empa's Advanced Fibers Laboratory and one of the conference organizers, put it in his welcoming address.Innovation in this field generally takes place as a result of partnerships between groups drawn from various scientific disciplines. Just as important is the intensive cooperation between research institutes and industry, in Hufenus' opinion. The Fiber Society Spring Conference, which took place from the 23rd to 25th of May, represented the ideal platform for the exchange of ideas and know-how necessary to initiate and plan collaborative projects. The conference was held at Empa's St Gallen site, which has traditionally been heavily involved in innovative work in the textile field.
There was enormous interest in the event, and the organizers received about twice as many suggestions for expert presentations as they were able to consider. Altogether over 200 scientists from 20 countries attended the event. "The conference deals with the practical applications of today's fiber research," explained Hufenus, whose own work involves developing novel fibers with his team. One such example is a fiber for making protective jackets which, although acting like armor to shield the wearer from heavy blows, is still pliant and supple so that the jacket is comfortable to wear.
The symposium showed that there is a general trend for textiles to find use in new areas of application with high added value, for example in the medical field where implants made of textiles are being used to replace blood vessels or heart valves. The latest developments in conductive fibers are leading to a fusion of electronics and textile technology, with an appropriately large potential for the monitoring of bodily functions and applications in telemedicine.
Empa is itself working intensively on a range of solutions in this very promising area; in all eight Empa staff members presented the latest results of their work during the conference, one being in the area of electrospinning – a process by which fibers of both polymer and purely inorganic material, as well as composites of both, can be manufactured with diameters in the nanometer range. This makes it possible for example to create novel nonwoven textile-based materials for applications in medical and filter technologies, and in catalytic processes.
#Vatdyes are different from reactive dyes, disperse dyes, basic dyes, acid dyes or azoic color but its application process is near similar as sulphur dyes. Vat dyes are used for coloring cellulosic fiber specially cotton fiber. It is widely used for run the dyeing process of cotton yarns which is used for producing jeans or denim product.
