NOVELTY - Performing blow molding process of renewable polyester fiber with low density involves preparing recycled polyester fiber as raw material for blow molding, blending the regenerated polyester fiber and low-melting polyester, and then slicing. A two-step injection stretch blow molding method is used, and blow-molded the slices to prepare a molded product. USE - Method for performing blow molding process of renewable polyester fiber with low density ADVANTAGE - The process has good inhibiting effect on the bacteriostasis performance by the graphene modified regenerated polyester fiber the carbon atom in the graphene does not have the chance of nutrient interaction between the bacteria and the outside, the bacteria is not directly lethal by the carbon atoms in the not graphene, it will not reach the nutrient supply and finally disappear for a long time. The bacteriodeostatic performance of the regenerated polymer fiber is excellent. The blow-molded product wall thickness is uniform, and saves time and increases production efficiency.
