High-quality products should be controlled from the source. During the production process, Bethune set up six inspection points. During the production of meltblown fabrics, real-time sampling inspections are carried out to ensure product quality. When the meltblown fabrics arrive at the mask production workshop, they will be further sampled and tested to ensure the meltblown fabrics again. It is qualified. After the mask product is produced, a random inspection of the filter efficiency of the mask will be carried out to ensure that the final product meets the standard.
