A process for quantifying the moisture in a blanket of fibers includes the emission of an incident electromagnetic wave towards the blanket, by at least one emitter; the receiving of the electromagnetic wave transmitted through the blanket, by at least one receiver; the identification of a variation of at least one parameter of the transmitted wave relative to the incident wave; the determination of a representative value of moisture in the blanket of fibers, as a function of the variation and of the effective volume of blanket that has actually interacted with the incident wave. 1. A process for quantifying the moisture in a blanket of fibers , comprising:emitting an incident electromagnetic wave towards the blanket, by at least one emitter,receiving the electromagnetic wave transmitted through the blanket, by at least one receiver,identifying a variation of at least one parameter of the transmitted wave relative to the incident wave,determining a representative value of the moisture in the blanket of fibers, as a function of said variation and of an effective volume of blanket that has actually interacted with the incident wave.2. The process as claimed in claim 1 , wherein the incident wave is a microwave.3. The process as claimed in claim 1 , wherein a variation of one parameter of the transmitted wave relative to the incident wave is a phase shift.4. The process as claimed in claim 1 , wherein a variation of one parameter of the transmitted wave relative to the incident wave is a change in amplitude.5. The process as claimed in claim 1 , wherein the representative value of the moisture in the blanket of fibers corresponds to an actual amount of water that has interacted with the incident wave claim 1 , referred to as effective amount of water.6. The process as claimed in claim 5 , wherein the effective amount of water is determined by means of a mathematical relationship giving the variation of one parameter of the transmitted wave relative to the incident wave ...
