Abstract
An industrial absorbent and methods of manufacturing the same. In one embodiment, the industrial absorbent includes a first scrim made from at least one thermoplastic material; a second scrim made from at least one thermoplastic material; and a middle layer positioned between the first and second scrims. The middle layer includes a dry-laid web of fire-retardant treated cellulose and opened, individuated staple bicomponent fiber. At least some of the bicomponent fiber in the middle layer is thermally bonded to at least some of the cellulose in the middle layer, and the first and second scrims are thermally bonded to the middle layer.
