ABSTRACT:
An exhaust particulate filter for a diesel engine which is high in collecting efficiency of exhaust particulates and small in pressure loss, by using a felt-like body having pores of an optimum inner diameter between heat resistant inorganic lengthy fibers. Wire nets (31) formed of heat resistant metal are put upon both upper and lower surfaces of felt-like body (32), which are arrested from both the surfaces thereof by heat resistant yarn (33), the felt-like body (32) being configured such that heat resistant inorganic lengthy fibers cut into a predetermined length are irregularly oriented in a horizontal direction and laminated, to which needles are applied, and the inorganic lengthy fibers are vertically entangled.
