Abstract
In making entangled fibrous products by depositing fibers from streams of hot gas in which they are entrained, dust suppressant incorporated in the product by introducing at least a portion of it into the cooler region surrounding and separating the fiber-entraining streams of hot gas and communicating with the zone wherein the fibers are deposited minimizes smoke evolution as compared to introducing such portion into the hot gas streams.
