BIODEGRADABLE NONWOVEN FABRIC IMPROVED IN FLEXIBILITY AND SOFTNESS, PREPARATION THEREOF AND BIODEGRADABLE MASK USING THE SAME

摘要

According to the present invention, (i) PLA-PBAT resin blend, (ii) PLA-PBAT oligomer block copolymer, and (iii) additives; A biodegradable mask using the same is provided, wherein (i) the PLA-PBAT resin blend is a mixture containing polylactic acid (PLA) resin and polybutylene adipate-terephthalate (PBAT) resin; The (ii) PLA-PBAT oligomer block copolymer is a compatibilizer, and the PLA oligomer block and the PBAT oligomer block may be linked by a linking group derived from a polyfunctional compound having a straight-chain hydrocarbon group having 3 to 12 chain atoms; and (iii) the additive may be selected from the group consisting of a plasticizer, an inorganic filler, an antioxidant, a slip agent, and an anti-blocking agent. According to the present invention, by improving the compatibility and radioactivity of the biodegradable resin, it is possible to economically manufacture a biodegradable nonwoven fabric having improved flexibility and ductility and a biodegradable mask using the same.
