<p>Biodegradable fibers used in cigarette and cigarette filter are provided. Raw material components of said biodegradable fibers comprise 90-100% of polylactic acid modified with copolymerization of non-lactone monomer and 0-10wt% of stabilizer. Said polylactic acid modified with copolymerization of non-lactone monomer is a polymer containing 1-30% of chain sections of non-lactone monomer based on total number of chain sections and chain sections of polylactic acid as remainder in molecular chain, and weight average molecular weight thereof is 50,000-350,000, and polydisperse index is 1.2-3.0. Said fibers used in cigarette are prepared by process of melt spinning of the raw materials. Biodegradable cigarette filter rod prepared by the fibers used in cigarette through setting process and cigarette products are also provided.</p> |
