Abstract
The present invention addresses the problem of providing a twisted cord of liquid-crystal polyester multifilaments which gives various high-order processed products capable of retaining desired product shapes and which is suitable for use in general industrial material applications such as high-strength ropes, slings, and nets. The twisted cord of liquid-crystal polyester multifilaments has a coefficient of variation in longitudinal-direction cord diameter, X, of less than 30%.
Claims11
A twisted cord of liquid-crystal polyester multifilaments, the twisted cord having a coefficient of variation in cord diameters in a longitudinal direction, X, of less than 30%, the coefficient of variation in cord diameters that is calculated from (Formula 1) described below:
- Coefficient of variation in cord diameters, X (%)={standard deviation of cord diameters in a longitudinal direction, σ (mm)÷average cord diameter, D (mm)}×100 (Formula 1).
