(2) Electrostatic dust absorption test
The bottom of the culture dish is fully paved with soot, and the tissue to be tested is cut into a square with the side length larger than the diameter of the culture dish. After the sample is rubbed on a plastic or rubber stick for 50 times, the lower part of the friction surface of the sample is covered on a culture dish (the sample is kept in a straight state at the mouth of the culture dish), the fabric is taken down after 1min, and the grade 5 is the best grade, and the grade 1 is the worst grade according to the amount of the adsorbed cigarette ash on the sample. The rating scale is: 1, the friction part of the sample is full of soot; 2, more soot adheres to the friction part of the sample; grade 3, some soot adheres to the surface of the sample; level 4, slight soot adhesion on the surface of the sample; and 5, no soot is adhered to the surface of the sample. The test results are shown in Table 2.
