Title:

WET NONWOVEN FABRIC FOR HYDROCARBON TRAP OF GASOLINE ENGINE AIR CLEANER AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2020/027356

Kind Code:

A1

Abstract:

The present invention relates to a wet nonwoven fabric for a hydrocarbon trap of a gasoline engine air cleaner and a method for producing same and, more specifically, to a wet nonwoven fabric for a hydrocarbon trap of a gasoline engine air cleaner and a method for producing same, in which powdered activated carbon having specific physical properties, pulp, a synthetic fiber of specific properties, and a carbon binder are prepared as basic raw materials, the materials are made into a web-type nonwoven fabric, the web-type nonwoven fabric is formed into a wet nonwoven fabric of a predetermined thickness through compression, and the wet nonwoven fabric is produced as a hydrocarbon trap, and when the hydrocarbon trap is installed in a gasoline engine air cleaner and used, the wet nonwoven fabric may adsorb oil mist such as hydrocarbons contained in evaporated gas generated from a combustion chamber of an engine or fuel of a fuel storage tank, and then desorb same when the engine is running, thereby preventing external leakage of hydrocarbons, which is the main cause of air pollution, and minimizing damage caused by hydrocarbon gas to a passenger in a vehicle.
