Definitions
- the natural organic fibers freshly coated with the aqueous binder composition conveyed by a flow of hot air. They are therefore not liable to adhere massively to the equipment for forming the mat of fibers and the method can operate in an installation without a washing water system operating in a closed circuit.
- the organic natural fibers sized with the aqueous binder composition are first subjected to drying before to be transported, possibly mixed with other fibers, shaped and baked in an oven.
- thermosetting natural organic fibers impregnated with aqueous thermosetting binder composition so as to obtain a set of thermosetting natural organic fibers
- 100 parts by weight of the set of thermosetting natural organic fibers are mixed with 10 to 900 parts by weight, preferably with 10 to 400 parts by weight, preferably with 20 to 300 parts by weight, in particular with 30 to 200 parts by weight of other fibers (non-binding fibers).
- the shaping of the set of thermosetting natural organic fibers can be done for example by compression by means of a roller located at the inlet of the baking oven. on a conveyor.
- the heating temperature of step (e) is advantageously between 130°C and 155°C, preferably between 135°C and 150°C.
- the heating time is advantageously between 30 seconds and 15 minutes, preferably between 1 minute and 10 minutes, in particular between 2 and 8 minutes.
- thermosetting lignocellulosic fibers containing binding natural organic fibers surrounded by a dry layer of thermosetting organic binder and non-binding fibers.
- These natural organic fibers are in bulk, that is to say they are in the form of individual fibers which can be intermingled, but which do not adhere to each other so as to form a mattress of fibers.
- thermosetting natural organic fiber assembly of the present invention provides a stable, non-sticky intermediate product that can be stored, transported and processed under ambient conditions of temperature and relative humidity.
