Abstract (en)

[origin: WO9517353A1] A method for depositing a substance, or a mixture of substances, on fibres of a fibrous material, in particular of a mineral fibre material, wherein each substance, or a precursor material thereof, in gaseous state at a temperature above the temperature of the fibrous material is made to penetrate into the fibrous material, and which, preferably part thereof, is deposited on the fibres by condensation. The substance or the precursor material thereof may be mixed with a transport gas having a substantially lower dew point temperature than the substance so as to form a polynary gaseous mixture which is made to penetrate into the fibrous material, with the fibrous material being held at a temperature below the dew point temperature of the gaseous mixture so that part of the substance or the precursor material thereof is deposited on the fibres by condensation.
