Guest Post: Effects of Twist on Cord Properties

Spending years in materials science in the tire and rubber industry, I have found large volumes of publications available on most performance aspect of cord properties (strength, elasticity, fatigue, adhesion), and when I run across something on twist I usually make a note of it. I have seen less published data and information available on the effect of twist level on textile cord properties. I have collected a few “rules of thumb” from Takeyama and Fujimoto. Recently at Hailide America Inc, we have looked at the twist effects in an industrial-grade high-tenacity polyester and have found the old tire-cord-twist rules of thumb that apply are actually inverted in the low twist region.
