▎ 摘  要

NOVELTY - Adjustable resistance bacteriostatic meltblown cloth comprises 87-97.5 pts. wt. polypropylene, 0.4-10 pts. wt. graphene, and 1-10 pts. wt. electret masterbatch. USE - The adjustable resistance bacteriostatic melt blown cloth is useful in preparing fruit and vegetable packaging bags (claimed). ADVANTAGE - The adjustable resistance bacteriostatic meltblown cloth: can adjust the airflow resistance without changing the processing parameters of the meltblown non-woven fabric by adding graphene and electret masterbatch, improves the antibacterial performance of the meltblown non-woven fabric, the antibacterial rate can be as high as 99.9%, the range of airflow resistance can be controlled within 10.2-27.4Pa, which can meet the respiratory intensity of most types of fruits and vegetables. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the adjustable resistance bacteriostatic meltblown cloth; and (2) a fruit and vegetable packaging bag prepared by the resistance-adjustable antibacterial meltblown cloth.
