A METHOD FOR CONTINUOUS IMPREGNATION OF ORGANIC,MINERAL OR METAL FIBRES WITH A SOLID PULVERULENT SUBSTANCE IN SUSPENSION IN A GAS,AND APPARATUS FOR THE APPLICATION THEREOF

摘要

The method comprises the continuous passage of said fibers in an aerosol, optionally in movement, with a substantially constant concentration of particles or microparticles of said pulverulent polymeric products in a gas, said passage being followed by a thermal treatment and a shaping operation. The plant for implementing such method comprises a housing (1) provided with supply means (3-9) for an aerosol-type suspension of polymers from an aerosol generator (2) supplied with compressed air (4) and a means for the circulation (10) of the fibers in said housing.
