Abstract

The invention discloses a making method of 1670-dtex / 2-PEN impregnation tire fabric used for taking radial tire cap ply. The making method specifically includes the steps of twisting, weaving, impregnating, winding and finished product making and obtaining. The invention further discloses the 1670-dtex / 2-PEN impregnation tire fabric used for the taking radial tire cap ply, the 1670-dtex / 2-PEN impregnation tire fabric used for the taking radial tire cap ply is obtained with the making method, and the drying shrinkage of the 1670-dtex / 2-PEN impregnation tire fabric used for the taking radial tire cap ply is smaller than or equal to 1.6% when the temperature is 177 DEG C. The 1670-dtex / 2-PEN impregnation tire fabric is high in modulus and free of creeping deformation, and has the better size stability.

Description

technical field [0001] The invention belongs to the technical field of polymer fiber production, and in particular relates to a method for preparing a 1670dtex / 2PEN dipped cord fabric used for the cap ply of a passenger radial tire. The invention also provides a method for the cap ply of a passenger radial tire 1670dtex / 2PEN dipped cord fabric. Background technique [0002] It has become an indisputable fact that the revolution of tire structure and the improvement of product performance cannot be separated from the renewal of skeleton materials. Radial tires have long been the development direction of tires. At present, the material of semi-steel radial tire crown belt is basically nylon 66. However, for high-speed, high-performance tires, nylon has obvious shortcomings in dimensional stability. In contrast, PEN fiber has been paid more and more attention due to its high modulus, high dimensional stability and other performance advantages and acceptable cost performance, ...
