Abstract:
A polyester dipped cord cloth, which is produced by subjecting at least two strands of polyester multi-filamentary yarn to first twisting and second twisting, to form a twisted cord, said polyester multi-filamentary yarn comprising 90 mol % of polyethylene terephthalate; forming the twisted cord into a fabric; and treating the fabric with blocked isocyanate and resorcinol formaldehyde latex (RFL), wherein the cord treated with RFL satisfies the following characteristics:a) a tenacity of 5.0 g/d or greater, b) a dimensional stability index (E4.5+SR) of less than 7.0%, c) a breaking elongation of 9% or greater, and d) an intermediate elongation difference (E1âˆ’E0) of 3% or less, wherein the intermediate elongation E0 is the elongation under a load of 4.5 g/d and the intermediate elongation E1 is the elongation under a load of 4.5 g/d after conducting a thermal treatment 177Â° C. for 10 min. under load of 0.01 g/d.
