Abstract

PURPOSE: To improve filter mediums in dust collection efficiency by making tanning treatment thereof, causing fine cracks thereto and/or making fluffing thereof.
CONSTITUTION: Various kinds of filter mediums are improved in dust collection efficiency by making tanning treatment including bending, beating, extending and massaging thereof; by causing fine cracks thereto; or by making fluffing thereof. Thereby, said filter mediums can be reduced in air passage resistance. Table shows for comparison the test results of various kinds of filter mediums whose thickness and air passage resistance are adjusted to 3mm and 3mmAq respectively and which have been treated and not treated by a mechanical means for this method.
