Abstract

The present invention provides a thin layer capply and a low-weight tire to which the thin layer capply is applied. The thin layer capply of the present invention has effects of reducing a rolling resistance of the tire through a weight reduction and improving fuel efficiency of a vehicle in which the tires are mounted while maintaining stiffness required for the tire, by forming the cord spinninglayer in a thin tape form by spinning and depositing a plurality of cord strands, rather than twisting a plurality of cord strands to form the capply cord.

Description

[0001] related application [0002] This application claims priority from Korean Patent Application No. 10-2017-0161612 filed with the Korean Intellectual Property Office on November 29, 2017, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a cap ply for a tire and a low-weight tire using the cap ply, and more particularly, to a thin cap ply in which a cap in the form of a thin belt is formed by textile cord strands The belt cord is manufactured so that the same rigidity can be maintained as a whole and the weight of the tire can be reduced, as well as a low-weight tire involving the application of the thin layer cap ply. Background technique [0004] In order to reduce the weight of the tire, it is necessary to reduce the weight while maintaining the strength or rigidity of the tire by applying various low-weight reinforcing materials. As a solution thereof, there is a method of reducing the thi...
