Abstract

The present invention relates to a hyaluronate nonwoven fabric composed of hyaluronate fibers and a manufacturing method therefor, wherein a nonwoven fabric composed of only pure hyaluronate is provided without the addition of any heterogeneous fiber, such as PVA which is a binding fiber essentially added during a wet-laid nonwoven fabric manufacturing process, so that a nonwoven fabric composed of only hyaluronate fibers with excellent human compatibility and without cytotoxicity, skin irritation, and the like can be provided, and thus can be used as patches for cosmetic patches, wet wound dressings, tissue adhesion barrier membranes, and the like.

Abstract

The present invention relates to a vehicle exhaust gas abatement apparatus. The automotive exhaust gas abatement apparatus comprises: an exhaust gas discharging unit which is provided on one side with an exhaust gas discharging passage through which exhaust gas generated from an engine of a vehicle is exhausted; a catalytic converter which is connected to a rear end of the exhaust gas discharging unit along a direction in which the exhaust gas is discharged, and which removes harmful substances in the exhaust gas by using a catalyst; and a surface combustion unit which is coupled to one side of the exhaust gas discharging unit and heats the inner portion of the exhaust gas discharging unit such that the exhaust gas is heated to an activation temperature of the catalyst or higher so as to reach the catalytic converter.
