Abstract
A method of spraying fiber-containing fluids that results in smoother, more uniform coatings. The method comprises displacing a fiber-containing fluid through a nozzle assembly at about 69 KPa to about 386 KPa. The fibers have a length of about 1 mm to about 6 mm. The nozzle assembly comprises a nozzle extension, an elbow joint, and a nozzle in series communication through at least two hollow fluid passages. A first fluid passage exits at a first nozzle outlet having a diameter of about 2.5 mm to about 3.5 mm. A second gas passage exits at a second nozzle outlet and directs a gas at the fiber-containing fluid to atomize the fluid. Control means are disposed upstream of the nozzle assembly for controlling the fiber-containing fluid flow and the gas flow.
