Abstract
A system and method for applying de-dusting agents to fibrous mats, webs, and/or blankets requiring a lower usage of the de-dusting agents, and producing fibrous products having improved dust suppression are disclosed. The dedusting agent or agents are first reduced to very fine particles or droplets and then, in an air suspension, are passed through the fibrous mat, web and/or blanket to deposit the very fine particles or droplets onto the surfaces of the fibers.
