- Abstract
- Purpose:Pollen may spread indoors through clothes contaminated during outdoor activities. This study aimed to evaluate the pollen removal efficacy of a mechanical dryer.Methods:Cotton clothes served as laundry, and fabrics measuring 2 x 5 cm served as test samples. Pollen was spread evenly on the test fabrics. The fabrics were then fixed on the cloth and left for 8 h to imitate real-life conditions. This experiment was conducted under 2 conditions, wet (after washing clothes) and dry (without washing). After drying, we counted pollen on the test fabrics to evaluate the pollen removal rate. We measured the remaining allergens in extracts from the contaminated fabrics after mechanical drying. The concentrations of allergens (Amb a 1, Bet v 1, Crp j 1, and Phl p 1) in each extracted solution were measured using 2-site ELISA.Results:For ragweed, Japanese cedar, birch, and timothy grass, the mean pollen removal ratios for the dry samples were 99.88 +/- 0.09%, 99.96 +/- 0.03%, 99.89 +/- 0.02%, and 99.82 +/- 0.11%, respectively, and those for the wet samples were 98.83 +/- 0.87%, 97.91 +/- 1.81%, 97.29 +/- 1.19%, and 96.3 +/- 0.92%, respectively. Further, for the pollen allergens Amb a 1 [ragweed], Crp j 1 [Japanese cedar], Bet v 1 [birch], and Phl p 1 [timothy grass], the mean pollen allergen removal ratios for the dry samples were 99.81 +/- 0.06%, 99.94 +/- 0.23%, 99.90 +/- 0.11%, and 99.84 +/- 0.17%, respectively, and those for the wet samples were 98.11 +/- 0.14%, 96.04 +/- 1.52%, 97.21 +/- 0.83%, and 95.23 +/- 0.92%, respectively. There was no statistically significant difference for each species.Conclusions:Mechanical drying effectively removed pollen and allergens from dry and wet fabrics. We expect that further studies on the removal of other indoor allergens would contribute to improved environmental control for allergy patients.
