Abstract:

To enhance the repeatability and reproducibility of the method for testing the hair-loss quantity according to the standard Raised Silk Scarf and Shawl (FZ/T 44007-2019), and to avoid test failure, the method was studied. The sample area was measured using several different methods. A suction filtration experiment was performed using sand core funnels with four different pore diameters. A hair-loss experiment was then performed using sand core funnels with different pore diameters by different measurement means. The research results showed that different measurement locations and measurement methods may lead to great differences in the sample area results. The adoption of sand core funnels with different pore diameters had different suction filtration efficiency, and also affected the experiment results. Finally, recommendations for test method improvement were proposed. By specifying the effective area measurement method of the sample and the pore diameter of the sand core funnel, it is hoped to improve the repeatability and reproducibility of the experiment.
