Definitions
- a polyamide fiber is made into a twisted cord, and then treated with an adhesive (hereinafter also referred to as "dip"), and then the twisted cord is subjected to tension.
- a method of tension heat treatment is known. Twisted yarn cords have been subjected to tension heat treatment at higher tensions in order to obtain reinforcing cords with higher strength and higher rigidity. By doing so, the strength after the dip treatment is increased, contributing to further weight reduction of the tire and making it possible to use the tire for higher load applications.
- the room temperature (25°C) knot strength of the polyamide fiber for tire cord of the present embodiment is preferably 4.5 cN/dtex or more and 6.5 cN/dtex or less, more preferably 5.0 cN/dtex or more and 6.0 cN/dtex or less. More preferably, it is 5.2 cN/dtex or more and 5.8 cN/dtex or less.
- the 25° C. knot strength is 4.5 cN/dtex or more, it is possible to suppress breakage of the cord under tension heat treatment.
- the knot strength at 25° C. is 6.5 cN/dtex or less, the production can be carried out without significant decrease in process stability due to increase in fluff and yarn breakage.
- the tensile strength of the polyamide fiber for tire cord of the present embodiment is preferably 8.7 cN/dtex or more and 11.0 cN/dtex or less, more preferably 9.0 cN/dtex or more and 10.5 cN/dtex or less, and still more preferably 9.0 cN/dtex or more and 10.5 cN/dtex or less. It is 4 cN/dtex or more and 10.2 cN/dtex or less.
- the tensile strength is 8.7 cN/dtex or more, the tensile strength is excellent and contributes to the expression of the air knot strength and the knot strength.
- the tensile strength is 11.0 cN/dtex or less, production can be carried out without significant deterioration in process stability due to increased fluff and yarn breakage.
- the dimensional stability of the polyamide fiber for tire cords of the present embodiment is preferably 12% or more and 20% or less, more preferably 15% or more and 19% or less, and still more preferably 16% or more and 18% or less.
- the dimensional stability can be determined from the sum of the boiling water shrinkage of the fiber and the intermediate elongation (elongation at a high load of 1/2 of the breaking strength).
- the dimensional stability is 12% or more, the toughness in rubber reinforcement applications such as tire cords is improved.
- the dimensional stability is 20% or less, it contributes to maintaining strength at high temperatures, is excellent in tensile strength at high temperatures, and contributes to the expression of air knot strength under a temperature of 180° C. and knot strength at 25° C. .
- the coating amount of the finishing agent is less than 0.5% by weight, the effect of reducing frictional resistance (smoothness) between the extreme pressure property and the metal surface is insufficient, making it difficult to stably produce high-strength polyamide fibers.
- the coating amount of the finishing agent exceeds 1.5% by weight, the penetration of the dipping liquid into the polyamide fiber is inhibited during the dipping treatment, resulting in a large decrease in adhesion to the rubber.
- Disarrayed filaments include single yarns of twisted yarn cords that are loose or fluffed, which may cause thickness unevenness when made into a blind. Twisted filament turbulence was evaluated based on the following criteria for 1,000 twisted cords and 1,000 m. (Evaluation criteria) ⁇ : Filament disorder is less than 1.0; ⁇ : 1.0 or more and less than 5.0 filament disturbances; ⁇ : 5.0 or more but less than 10.0 filament disturbances; x: 10.0 or more filament disturbances.
- Example 5 The same procedure as in Example 1 was carried out, except that the air supply energy was changed to 1.0 kW in the entangling step. The results are shown in Table 2 below.
- Example 5 The procedure was carried out in the same manner as in Example 1, except that in the refueling step, a finishing agent containing no ionic surfactant was added so that the deposition rate was 1.1% by weight. The results are shown in Table 2 below.
- Example 8 The entanglement process was carried out in the same manner as in Example 1, except that the air supply energy was changed to 0.8 kW. The results are shown in Table 2 below.
