  • Use of a vegetal or plant fiber
    Publication number: 20040093696
    Abstract: A fiber material from the fruits of poplars, willows, composites or similar plants is suitable for use as a raw material for insulation, for the production of fiber mattresses or as a filling or padding material. The fiber material can be extracted from closed fruits with the plants being dried and/or opened using an air flow and agitated in a treatment chamber (17), whereby the fiber material (21) contained in the fruit capsules (19) is substantially separated from the other constituent parts of the fruits. Disadvantages related to the use of cotton are thereby avoided.
