Mainly bias tire, the Fypro that tyre cavity cord uses mostly, that is, the nylon being commonly called as, because it has the high spy of intensity
Put and be widely used, but because its heat endurance is poor, once making it in the short time without interior cold technique after vulcanization terminates
Interior cooling, terminate just to occur that cord shrinks and has influence on the size and dimension of tire when internal pressure reduces in vulcanization.Compare
Compared with nylon cord fabrics, polyester cord has intensity close with its and the characteristics of heat endurance will be apparently higher than nylon, generally,
The dry-hot shrinkage of nylon cord fabrics is 6% or so, and polyester cord is less than 2%, selects polyester cord to replace nylon cord fabrics for this
Use, it is ensured that without it is interior it is cold under conditions of reduce tyre cavity cord contraction.
