PURPOSE:To provide the subject cord causing no strength drop-off in its dipping and curing processes, also excellent in the fatigue resistance under repeated compressive strain. CONSTITUTION:The objective cord <=8.0g/d in the tenacity after cured in rubber, treated with a specific adhesive liquor. This adhesive liquor has the following characteristics: (1) each of the following parameters fall within a specified range: (a) molar ratio of the total resorcin to the total formaldehyde in the solution; (b) weight ratio of a total of the resorcin and formaldehyde to the total rubber latex solid fraction; (c) wt.% of the alkali metal hydroxide solid fraction based on the total solid in the RFL adhesive liquor; (d) wt.%, on a NH4OH basis, of the aqueous NH3 solution added based on the total solid; and (e) the total solid concentration (%); (2) the rubber as a component of the latex in this adhesive liquor is specified. |
