Title:
タイヤコード用ライオセル繊維およびこれを含むタイヤコード
Document Type and Number:
Japanese Patent JP5340277
Kind Code:
B2
Abstract:
The present invention relates to a lyocell fiber to which is performed a wet-treatment under a saturation vapor pressure state for 10 minutes at a temperature of 120¡É and then subsequently a dry-treatment for 2 hours at a temperature of 130¡É, wherein the strength of the lyocell fiber is higher than the strength of the untreated lyocell fiber, when measured 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 a water-washing condition of a spinning machine, thereby improving dimensional stability of a tire cord when it is applied to the tire cord.
