Abstract

PURPOSE: To prevent filter cloth from clogging, to enhance dimensional stability, and to eliminate uneven waving phenomena at selvage portion by using polyester based fiber containing specific amount of acid group substituted with alkali metal.
CONSTITUTION: Normal polyester based fiber is copolymerized with a single or mixed vinyl monomers such as sodium (meth)allyl sulfonate, sodium styrene sulfonate, and (meth)acrylic acid. The fiber is then treated to contain 1.3×102W 4.2×103mol/106 gram-fiber of acidic group such as sulfonic acid and carboxylic acid substituted with alkali metal such as Na and K. The fiber is used to make filter cloth of woven cloth, non-woven cloth or structure of these combination. This filter cloth can be used as dry type filter, but is particularly preferable as endless type wet-system belt filter.
