| Abstract: | All types of surfactants (cationic, anionic and nonionic) reported in this paper could enhance the surficial wettability of polypropylene (PP) and polyethylene terephthalate (PET) nonwoven fabrics. However, the effects of cationic and nonionic surfactants were better. The longer the treatment time of surfactants on the nonwoven fabrics, the better the surficial wettability. The surficial rewetting time would no longer change above a certain treatment time. The rewettability of nonwoven fabrics could be evidently improved just when the concentration of surfactants was just above the CMC, except for sodium dodecylbenzene sulfonate (LAS). The finer the fibers and the looser the structures, the better the surficial rewettability of nonwoven fabrics. |
