PAPERMAKING MACHINE FABRICS, FILTERS AND REINFORCING LAYERS FOR ELASTOMERS COMPRISING MONOFILAMENTS COMPRISING SPECIFIC COPOLYESTERS, STABILIZED COPOLYESTERS AND USE OF COPOLYESTERS FOR MANUFACTURING PAPERMAKING MACHINE FABRICS, FILTERS AND R INFORCING LAYERS FOR ELASTOMERS

摘要

Papermaking machine fabrics, filters and reinforcing layers forelastomers comprising monofilaments comprising specific copolyesters,stabilized copolyesters and use of copolyesters for manufacturingpapermaking machine fabrics, filters and reinforcing layers forelastomersDescribed are papermaking machine fabrics, filters and reinforcinglayers for elastomers, comprising monofilaments comprising copolymerscontaining 85 to 99 mol % of the structural repeat unit of the formula ? (?) , and1 to 15 mol % of the structural repeat unit of the formula ??-OC-R-CO-O-R3-O- (??),where R1 is a radical of a dihydric aliphatic or cycloaliphatic alcohol oris derived from mixtures of such alcohols,R is a radical of an aliphatic, cycloaliphatic or monocyclic aromaticdicarboxylic acid or is derived from mixtures of such dicarboxylic acids,R3 assumes one of the definitions for R1, and the quantitative data arebased on the total amount of the polymer.
