PLCPAは，溶融成形性に優れ，かつ高強度化できる，
また熱による寸法変化が少ない，またさらに吸水率が少
ない等の理由から，近年，広く展開されはじめた。PLCPA has excellent melt moldability and can be strengthened.
In addition, it has started to be widely used in recent years because of its small dimensional change due to heat and its low water absorption.

な効果が得られていない。However, it was a big drawback that it was melted by heat after melt molding. Japanese Patent Laid-Open No. 50-157619 discloses a method of heat-treating under nitrogen for a long time in order to improve the above problems and to improve the strength of the fiber.
However, this publication has a major drawback in that heat treatment is required for an extremely long time and the cost is very high.
In order to improve such a defect, Japanese Patent Application Laid-Open No. 61-289178 discloses a method in which a yarn is coated with a heat strengthening accelerator composed of an alkali metal salt and then heat treated. According to this method, the heat treatment time can be shortened, but it is still inadequate and a sufficient effect of improving heat resistance has not been obtained.

However, it is generally preferable that the heat resistance accelerator is 3 parts or more with respect to 100 parts of PLCPA. Particularly preferred is 5 parts or more, more preferably 8 parts or more. If it is less than 3 parts, the heat resistance of PLCPA often does not increase.
