Conductive fabric filter, method for manufacturing the same and electric dust collector having the same

An electric dust collector comprising:

• conductive fabric filters each comprising:
• a non-woven fabric coated with copper by electroless plating, wherein the non-woven fabric has pores and is conductive;
• and
• a housing part comprising:
• an inlet through which air including a foreign material flows;
• an outlet through which the air without the foreign material is discharged;
• and
• a seating portion in which the conductive fabric filters are seated and spaced apart from each other at a predetermined interval between the inlet and the outlet, wherein
• the conductive fabric filters are configured such that, when opposite polarity DC voltages, between 1 V and 12 V, are applied to the conductive fabric filters, the conductive fabric filters include:
• a positive conductive fabric filter, to which a positive (+) electric charge is applied;
• and
• a negative conductive fabric filter, to which a negative (−) electric charge is applied, and
• fine dust particles in the air, that have a positive (+) electric charge while passing through the pores of the negative conductive fabric filter, are adsorbed to the negative conductive fabric filter, and fine dust particles in the air, that have a negative (−) electric charge while passing through the pores of the positive conductive fabric filter, are adsorbed to the positive conductive fabric filter.
