Completed funded project

The focus is on the development of a textile back covering with the following properties:

• Light and flexible
• Temperature resistant (-40 to 300°)
• Food safe, no release of harmful substances
• Washable and reusable
• Low energy consumption

Furthermore, the textile should be equipped with additional functions:

• Production data acquisition by means of RFID chips (Industry 4.0)
• Branding for targeted advertising

For the tests, thin canvas fabrics were made of p-aramid, which were coated with silicone to produce a permanent non-stick layer. In order to be able to use the textiles like a baking tray, they were stretched on a metallic frame. Baking tests showed that the temperature dropped less and heated up faster using the textile sheets than with the standard aluminum sheets. However, the air-impermeable coating makes it difficult for the hot air to circulate in the oven, so the baking program has to be adjusted.

Branding of the baked goods is best achieved by embossing in the silicone coating, which must have a certain depth to transfer to the baked goods. It is also possible to equip the textiles with RFID chips, but their functionality is limited due to the high temperatures.
