Abstract:
This invention relates to a process for the treatment of insulating materials in the supple, fluffy state, such as down, wherein the fluff of the down is subjected to a physical treatment adapted to take the filaments of the fluff into a substantially radial position, giving the fluff its maximum volume in which it is stabilized by the superficial deposit of a resin. The apparatus for carrying out the process comprises a dehydration enclosure in the form of a rotating drum with inner blades, hot air inlet and upper evacuation. The invention is more particularly applicable to the treatment of down for filling duvets, sleeping bags or the like.
