Degradable fiber containing PHBV (polyhydroxybutyrate-hydroxyvalerate) and preparation method of degradable fiber

摘要: The invention relates to a degradable fiber containing poly (hydroxybutyrate-hydroxyvalerate) (PHBV) and preparation method of the fiber. At present, technology PHBV has various defects. is mixture polylactic acid-containing binary mixture, 100 mass parts contains 1 89 11 99 mixture. acid P (3HB-co-4HB) or (butylene succinate) (PBS ) polybutylene terephthalate (PBAT). comprises following steps of: performing vacuum drying on respectively, then physical mixing in ratio, melt spinning, finally post treatment. good spinning property at low temperature high temperature, mechanical strength sustained stable soft handfeel; can effectively improve production efficiency reduce cost.
