DOPE FOR SPINNING LYOCELL, METHOD FOR PREPARING LYOCELL FILAMENT FIBERS THEREFROM, LYOCELL FILAMENT FIBERS PREPARED THEREFROM, AND TIRE CORD COMPRISING THE SAME

摘要

Dope for spinning lyocell, a method for preparing lyocell filament fiber, the lyocell filament fibers prepared therefrom, and tire cord including the same are provided to improve elongation by generating a micro hollow on the lyocell filament fiber after removing a void forming material. Dope for spinning lyocell includes cellulose, a void forming material, N-methylmorpholine-N-oxide and water. The void forming material is polyalkylene glycol. The amount of molecular weight on the average is 1.000 ~ 20,000. The content of the void forming material is 0.1 weight% ~ 0.5 weight%. The content of cellulose is 5 weight% ~ 35 weight%.
