We tested six non-woven samples and estimated the volume of SB that leaked onto absorption paper for each sample (Fig. 4) . Leakage volume was correlated with splash gun pressure for all samples except 10 and 11, which had flashspun fabric structures (Table 1 ). Samples 10 and 11 The pressure is increased step-by-step at 5-minute intervals. For example, if it was observed visually that the SB did not leak through a protective clothing sample at 3.5 kPa but did leak at 7 kPa after more than 15 minutes, the sample was classified into Class 3. The pressure is increased step-by-step at 5-minute intervals. For example, if it was observed visually that the SB did not leak through a protective clothing sample at 3.5 kPa but did leak at 7 kPa after more than 15 minutes, the sample was classified into Class 3. and samples 10 and 11. Based on these observations, the six non-woven samples were classified into low-, moderate-, and high-performance groups (i.e., samples for which leakage volumes at 21.3 kPa were > 100 μl, between 100 and 50 μl, and < 50 μl, respectively). The above findings indicate that quantitative differences in protection performance among samples were distinguishable by our modified test method.
