EASILY DYEABLE POLYLACTIC ACID FIBER

摘要

PURPOSE: Easily dyeable polylactic acid fiber is provided to clearly dye the fabric under upper pressure while maintaining biodegradability, antibacterial and fire retardant characteristic by injecting metal sulfonate group into a main chain of polylactic acid. CONSTITUTION: Easily dyeable polylactic acid fiber is manufactured by mixing a polyethyleneterephthalate copolymer having polylactic acid and metal sulfonate and forming a reforming polylactic acid composition which is a main component of modified polylactic acid. The mixed polymer composition comprises copolymer 10-50 weight% containing polylactic acid 50-90 weight% and metal sulfonate 1-30M%.
