Abstract
PURPOSE: To remove even foreign substances, attached to nonwoven metallic fibrous filters and not easily removable therefrom, with ease and certainty, by subjecting the spinneret filters to the combination of disassembly and decomposition with a salt, cleaning with ultrasonic waves and immersion in a nitric acid bath in a specific order.
CONSTITUTION: Spinneret packs are subjected to the disassembly and decomposition with a salt primarily to take out spineret filters, which are then immersed in a salt bath at 400W440°C, preferably in the direction perpendicular to the liquid surface and without laminating on each other for about 2hr. Thus, carbonized substances, etc. are decomposed with the salt secondarily. The filters are then introduced into a water bath, and subjected to the ultrasonic waves preferably in the cross direction of the filter surface to shake down the decomposed and carbonized substances. The filters are immersed in a 10W30% nitric acid bath preferably in the direction perpendicular to the solution surface without laminating on each other for about 2hr to dissolve and remove the residual carbonized substances and foreign substances. After washing with water, the filters are further subjected to the ultrasonic wave treatment in the same manner as described above.
