66 High-strength Nylon 66 filament having excellent strength ratio

摘要

The present invention relates to the properties of nylon 66 super-high tenacity (SHT) fibers, and relates to nylon 66 high-strength fibers capable of expressing high strength utilization by making the elastic modulus at break of 40 d/g or less. The nylon 66 high-strength fiber with high strength utilization rate manufactured according to the present invention can produce a fiber with a low elastic modulus at break, high yarn strength, and high cut elongation by controlling the yarn manufacturing process conditions. It can be widely used as industrial fiber such as sewing thread, rope, and hose reinforcement.
