摘要： Provided are a dust-collecting filter cloth that comprises a base fabric and web, wherein at least the web includes modified cross-section fibers of polyphenylene sulfide; and a bag filter made of the filter cloth. When fitted to an exhaust gas dust collector, the bag filter involves little pressure loss and ensures increased dust-collecting efficiency. As being resistant to heat and ensuring good dust-collecting efficiency, the filter cloth is useful for dust collection.

摘要： The polyester monofilament of this invention has a terminal carboxyl group concentration of not more than 10 equivalent weights/10.sup.6 g and contains an unaltered carbodiimide compound in an amount in the range of from 0.005 to 1.5% by weight and a fluorine type polymer in an amount in the range of from 0.01 to 30% by weight. The polyester monofilament of this invention has an excellent resistance to hydrolysis and proof against staining. When used under high temperature and high humidity conditions susceptible to hydrolysis and the collection of stains, as when used in a papermaking drier canvas, it brings about a notable effect of prolonging the service life of the canvas and lengthening the cycle of cleaning.
