LYOCELL FILAMENT FIBER AND CELLULOSE BASED TIRE CORD

摘要

The present invention relates to lyocell filament fibers and a cellulose-based tire cord, and particularly to lyocell filament fibers of which the swelling anisotropy defined in the specification is 1.1 to 1.4. Furthermore, the present invention provides a cellulose based tire cord of which the swelling anisotropy is 1.1 to 1.4. According to the present invention, there is an effect of providing the lyocell filament fibers and the cellulose based tire cord of which the dimensional stability in a highly humid state is particularly good and thus the tenacity, the elongation, and the modulus are superior to common cellulose based fibers, such as rayon and so on, the property maintaining rate at the post manufacturing process is high, and the processibility is good.
