It can be concluded that the coffee cup brush is made of pure nylon. Rheometer test method. With a tensiometer, the pulling force of the bundled filaments must be greater than 6kg, and the service life of the coffee cup brush can be most directly ensured without losing hair. Surface observation method. Carefully observe the presence or absence of uneven thickness and light leakage of the coffee cup brush on your hand, observe whether the gloss of the brush is consistent, and observe whether there are rust spots on the surface of the metal base.
