Abstract: A delivery system for delivering liquid fire retardant material to cotton batting during the course of producing the cotton batting includes a spray manifold arrangement including a liquid conduit carrying the fire retardant material under pressure, a parallel air manifold carrying air under pressure and a plurality of spaced nozzles distributed across the mainfold, each of which is connected to both conduits. This manifold is physically positioned in the cotton batt producing machines just downstream of the garnetting rollers where two separate thin webs of cotton are produced. These webs are impacted by spray from the nozzles just ahead of and at the point where the webs are combined. A tank containing the fire retardant material is connected to a regulated source of air under pressure some of which is supplied to put the contents of the tank under pressure such that it flows to the liquid conduit and some of which is supplied to the air manifold.
