Abstract:
A fiber prepared from a copolyester having a dicarboxylic acid component and a diol component, the copolyester comprising repeat units of the following structures: wherein the diol component comprises â€”Oâ€”R11â€”Oâ€” and â€”Oâ€”R12â€”Oâ€”, where R11 and R12 are selected from the group consisting of C2-C12 alkylene, C5-C10 cycloalkylene, C2-C12 oxyalkylene and mixtures thereof; wherein the dicarboxylic acid component contains both aliphatic dicarboxylic acid â€”Oâ€”C(O)â€”R3â€”C(O)â€”, and an aromatic or cycloaliphatic dicarboxylic acid component â€”Oâ€”C(O)â€”R14â€”C(O)â€”, wherein R13 is selected from the group consisting of C0-C8 alkylene, C2-C4 oxyalkylene and mixtures thereof, wherein the mole % of R13 is less than about 95% and is greater than 60% of the dicarboxylic acid component; and R14 is selected from the group consisting of C6-C10 aryl, C5-C10 cycloaliphatic and mixtures thereof wherein the mole % of R14 is from greater than about 5% and is less than 40% of the dicarboxylic acid component.
