Claims (21)

The hydrophobic organic ester immersion penetration control agent having a melting point of 27 ° C. or higher is applied to the synthetic polymer yarn based on the weight of the synthetic polymer yarn to 0.05% by weight or more. Method for producing a tire yarn that can be converted. The method of claim 1 wherein the modulator is a polyol ester. The method of claim 2, wherein the polyol ester is pentaerythritol ester. The method of claim 2 wherein the polyol ester is triglycerides. The method of claim 4, wherein the triglyceride is hydrogenated coconut oil. The method of claim 1 further comprising applying 0.05 to 0.5% by weight of ethoxylated nonionic surfactant based on the weight of the synthetic polymer yarn. The method of claim 5, wherein at least 0.25% by weight of hydrogenated coconut oil is applied based on the weight of the synthetic polymer yarn. 7. The method of claim 6, further comprising applying 0.001 to 0.05% by weight of an antioxidant compound based on the weight of the synthetic polymer yarn. The method of claim 1 wherein the synthetic polymer yarn is a polyamide yarn. 10. The method of claim 9, wherein the polyamide yarn is poly hexamethylene adipamide yarn. The method according to claim 1, wherein the breathability measured by the suction of the tire cord is at least 0.40 l / 30 minutes. The method of claim 11, wherein the tire cord has a stiffness of less than 40 g. 13. The method according to claim 12, wherein the breathability measured by the tire cord's suction is at least 0.7 l / 30 minutes. The method of claim 13, wherein the stiffness of the tire cord is less than 30 g. It is characterized by containing at least 0.05% by weight of a hydrophobic organic ester immersion penetration regulator having a strength of at least 9 g / den, a copper content of at least 40 ppm, and a melting point of at least 27 ° C on the surface of the polyamide yarn based on the weight of the polyamide yarn. And a polyamide yarn suitable for use as a tire yarn capable of converting into a tire cord having a breathability of 0.4 l / 30 minutes or more, measured by suction. 16. The polyamide yarn of claim 15 wherein the tire cord has a stiffness of less than 40 g. 17. The polyamide yarn of claim 16 wherein the modulator is pentaerythritol tetralaurate. 17. The polyamide yarn of claim 16 wherein the modulator is hydrogenated coconut oil. 17. The polyamide yarn of claim 16 wherein the polyamide yarn contains from 0.05 to 0.5 wt% of an ethoxylated nonionic surfactant based on the weight of the polyamide yarn on the surface of the polyamide yarn. 17. The polyamide yarn of claim 16 having a breathability of at least 0.7 l / 30 minutes and a stiffness of less than 30 g. The polyamide yarn according to claim 20, wherein the polyamide yarn is poly hexamethylene adipamide sine polyamide yarn. ※ Note: The disclosure is based on the initial application.
