Karl Kroyer demonstrates his new invention - "Air laid paper".
Karl Kroyer 1964
Her husband's employer Karl Kroyer had invited the Elsinore International Journalist Congress to witness the event of the year. The scene was set. Light dimmed. Mrs. Borud appears on top of the stairs bathed in light while she slowly, slowly strides her way down. She looks marvellous in the wedding gown - completely made of our new dry-formed non-woven air-laid paper. No one was allowed to get closer than five meters -and Oops, lights out and she disappeared.
Next the day the world knew the fantastic story of paper textile. Letters were pouring in, but the price for touching a paper sample and told how it is made was 25.000 USD.
An American company Grace negotiated better terms. If they were disappointed they should be allowed to have research of their own choice for the money. They got disappointed by what they saw and asked for a total sucrose process in stead. This took "Inventions on Demand" a big step forward.
It is now 40 years since Karl Kryer invented the air-laid technique - a method to produce paper by using air instead of water. This adds to the paper a variety of properties such as absorbent properties. The production is environmentally friendly. Since then the use of air-laid products produced with this technology has exploded. Here in Denmark we have made all the machines, but most products have so far been fabricated abroad. A new Danish company "Danish Air laid Technology A/S" will remedy this situation.
In more recent times, the earlier work by M&J Fibertech and DanWebforming, both also located in Denmark, has resulted in turn-key machine systems that allow the production of multilayer webs based on cellulose fluff pulp, synthetic fibres or mixtures.
The formed webs may be thermally bonded, latex emulsion bonded or both systems may be used. Napkins, diapers, tablecloth made by the air-laid technique is huge industry today.
