LYOCELL FIBER FOR TIRE CORD AND TIRE CORD COMPRISING THE SAME

摘要

The present invention relates to a lyocell fiber having superior the crystalline properties, which are measured by wet-treated and dry-treated condition under high temperature and high pressure conditions compared to measurement under standard conditions, and to a tire cord comprising the lyocell fiber. According to the present invention, the lyocell fiber has strength, elongation, and modulus that are superior to those of a conventional rayon, even when the lyocell fiber is wet- and dry-treated under high temperature and high pressure conditions by specifying water-washing conditions of a spinning machine, thereby improving dimensional stability of a tire cord when it is applied to the tire cord.
