ABSTRACT:
A tire cord fabric is provided, the weft of which is composed of thermally modified partially oriented polyester filaments overcoated with adhesive rubbery latex. The weft having a break elongation of at least 80%, a birefringence value of at least 0.03 and dry heat shrinkage of at most 5% at 150.degree. C. for 30 minutes. The fabric shows a superior dimensional stability during crazing process, eliminating undesirable displacement of the weft along the lengthwise of the warp. The wefts in the fabric are also able to expand without breakage during tire building step, enabling the warps to distribute evenly in a spaced relationship.
