FIELD: automotive industry.
SUBSTANCE: cord hybrid fabric for multilayer tire carcass relates to automotive industry, namely, to rubberized textile cord for pneumatic multilayer tires of radial and diagonal design. Impregnated and thermally treated cord fabric of polymer is made of threads twisted from fibers of polymer polyamide 6 and polymer polyamide 66, with caliber 2,800–3,100 dtex, wherein fibers of cord hybrid fabric of two types of fabric polymer is characterized by the following parameters in an impregnated and thermally treated condition: torsion number 160–240 rpm; minimum breaking load 450–550 N; intermediate elongation 3.0–3.5±0.5 % at 45 N.
EFFECT: high strength of cord tire fabric with reduced number of layers in multilayer tires.
