<P>PROBLEM TO BE SOLVED: To provide a composite yarn that is excellent in heat resistance and also satisfies a high tensile strength and a high breaking elongation at the same time. <P>SOLUTION: By paying attention to that a para-type whole aromatic copolyamide fiber obtained after a drying process or a one-stage drawing has a low elastic modulus in spite of having a high heat resistance, the core-sheath composite yarn is provided by combining the fiber and a high strength fiber having a high heat resistance and tensile strength. <P>COPYRIGHT: (C)2013,JPO&INPIT |
