FLAME-RETARDANT CELLULOSE FILAMENT FIBER, TIRE CORD, AND METHOD FOR PREPARING THE SAME

摘要

Flame retardant cellulose filament fiber, tire cord, and a method for preparing the same are provided to improve flame retardant by including a flame-retardant substituent. Flame retardant cellulose filament fiber includes a phosphorous based silicon flame retardant. A manufacturing method of flame retardant cellulose based fiber comprises the following steps of: spinning cellulose based spinning dope; coagulating the dope; washing the coagulated dope; and manufacturing the filament fiber by drying the washed dope. In the method, spin finish including a phosphorous-based compound and a silicon based compound is added on the cellulose based fiber additionally.
