Spunbond web for adsorption of petrochemical substances from liquids gases

摘要

An adsorption web for adsorption of petrochemical substances from liquid phases or for adsorption of odorous substances has at least one face coated with a polymer. At least one adsorption substance present is in the polymer as a filler and has micropores or mesopores or macropores.

主权项

1. A mat for adsorption of petrochemical substances from water, the mat comprising:
a porous base web of continuous polymer filaments and having at least one face; a layer of a polymer containing soot as a filler irreversibly coated on the one face, the soot having micropores or mesopores or macropores; a porous cover web of continuous filaments bonded over the polymer/soot layer to the one face; and buoyancy elements or solids between the base web and cover web and imparting to the mat a lesser density than that of water.
