Polypropylene (PP) and polyethylene terephthalate (PET) nonwoven fabrics were treated with a mixed aqueous solution of sodium carboxymethylcellulose (CMC) and iron lactate (FeLac), and their ventilation resistance R, coefficient of kinetic friction μ and electrification voltage V were measured to evaluate the changes in physical properties due to the treatment. The results showed the following: The R of the PP and PET nonwovens increased with processing treatment with CMC and FeLac mixed aqueous solutions, and was greater for PET nonwovens than for PP ones. The R of the treated fabrics increases with increase in the concentration of CMC in the treatment solution. The R of the CMC + FeLac treated fabrics is slightly lower at a moisture content of less than 5.4 % than in the dry state, whereas it increases as the moisture content increases to several hundred percent. The μ of PP and PET nonwovens increases with CMC + FeLac treatment and is even higher at higher moisture contents. Furthermore, the V of PP and PET nonwovens are suppressed by the CMC + FeLac treatment.
