Brief description of the treatment of natural fibers vegetable, in particular for use of these fibers for the insulation of buildings

摘要

This process comprises the successive steps consisting in: *) to treat the fibers by a first tearing (1) with a view to their ventilation, *) bringing the fibers to a processing tunnel (3) of the fibers by treating liquids (4), *) to treat the fibers by their mixing together with their wetting by the treating liquids (4), at a temperature of the order of between 30°C. and 60°C. for a period of time between 2mn and 10mn, successively to the inside of the rotating capacitances (5), respectively, in at least one of the respective sets of washing (6), of a flame-retardant treatment (7), processing, anti - parasitic (8), or even as a perfuming of treatment (9), liquid-proofing treatment (10) and treatment of the marking, *) to extract the liquids out of the fibers by their compression and the drying with hot air, *) convey the fibers to a storage station (16), at the output of which is arranged a second tearer (17), *) bringing the fibers to a packaging station (19).
