FILTER CLOTH FOR SEPARATING ACRYLONITRILE POLYMER AND METHOD FOR PRODUCING ACRYLONITRILE-BASED POLYMER SEPARATED BY CONTINUOUS ROTARY FILTER EQUIPPED WITH THE FILTER CLOTH

摘要

PROBLEM TO BE SOLVED: To provide a filter cloth capable of efficiently filtering and separating a polymer from the polymer suspension of an acrylonitrile-based polymer obtained by aqueous suspension polymerization.SOLUTION: A filter cloth for separating polymer particles from the suspension of the polymer particles obtained by the aqueous precipitation polymerization of an acrylonitrile-based polymer consisting of a fabric having a twill structure in which a polyester multifilament yarn having an air permeability of 3 cc/cm/sec or more and 27 cc/cm/sec or less and a cloth thickness of 0.17 mm or more and 0.30 mm or less is a constituent yarn is provided.
