FILTER WITH EXCELLENT HEAT-RESISTING PROPERTY

摘要

A filter with excellent heat-resisting properties according to the present invention has a structure in which a polyester spunbond nonwovens (A) are respectively laminated onto both sides of aramid filament nonwovens (B) dispersed with activated carbon. The present invention comprises an excellently heat-resisting aramid fiber nonwovens (A) and polyester spunbond nonwovens so as not to deform at a temperature lower than 180°C, and to improve working environment by not generating dusts caused by using glass fiber. The present invention is, therefore, useful for a car, a ship, and a filter in a painting room, which are run in a high temperature condition.
