Elmarco’s Nanospider technology is a modified electrospinning system which has been developed in co-operation with the University of Liberec and has the ability to process a wide range of polymers in diameters of 50-300nm into nonwoven webs of 0.1-5 gsm.

The fibres are formed by an electrostatic field from a thin film of an aqueous or solvent solution and a wide range of polymers, including PA6, PVA and PUR, as well as more exotic types such has chitosan and gelatine, have been successfully spun.

Centrifugal spinning is similar to electrospinning, using a high-speed rotating cylinder instead of nozzles or capillaries to create the fibres. It has a high productivity but fibres are not as fine, according to professor Oldrich Jirsak. In the electrospinning process high voltage is used to create and electrically charge a stream of polymer solution that is electrospun by capillary action using a spinneret.

“We would like to offer co-operation in the development of nanofiberous materials as we are fully aware of Japan being a country with enormous potential, open to new technologies,” said general manager and founder Elmarco Ladislav Mareš at the opening of the new Kobe office. “We believe that this branch office will move us closer to the needs and requirements of our customers and will help us to establish long term business relations.”

“The decision to start our operations on the Asian market originates from the company’s experience gained at international exhibitions confirming the main characteristics of Japan as well as of the Japanese clients which have a widespread usage of modern technologies and advanced infrastructure,” added Oldrich Jirsak.

At the ANEX 2006 nonwovens show in Tokyo in May this year Elmarco held practical demonstrations comparing a common sound absorbing material and made of nanofibrous layers using the Nanospider technology.
