Id Subject Object Predicate Lexical cue
T169 0-4 Sentence denotes 3.3.
T170 5-26 Sentence denotes Mechanical Filtration
T171 27-141 Sentence denotes The particle capture of an electret filter is contributed by both mechanical and electrostatic capture mechanisms.
T172 142-374 Sentence denotes An electrostatic capture mechanism significantly improves the quality factor (filtration performance per a unit resistance); and when the surface charges are decayed, filtration mostly depends on the mechanical capture of particles.
T173 375-608 Sentence denotes It is well accepted that IPA treatment removes the surface charges of filter media; therefore, the IPA-treated samples can be deemed as the mechanical filter (mechanical contribution noted as “mech. cont’n”) (Figure 2 and Figure 3B).
T174 609-764 Sentence denotes The performance above this level of filtration for the untreated respirators A and B is considered as the electrostatic capture mechanism (electr. cont’n).
T175 765-1040 Sentence denotes Disinfection treatments such as solvent immersion, UV, oven-dry, and microwaving seemed to have negligible impacts on the structural integrity (Figures S3 and S4); accordingly, there were no apparent changes in the resistance and mechanical filtration after those treatments.
T176 1041-1158 Sentence denotes Notable fiber damage was found in the laundered samples by the external force imposed during laundering (Figure S3A).
T177 1159-1187 Sentence denotes The physical damage of Resp.
T178 1188-1336 Sentence denotes A resulted in the decrease of resistance and mechanical filtration performance, corresponding to the lower filtration efficiency compared with Resp.
T179 1337-1339 Sentence denotes B.
