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 × 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.

机械干燥对花粉过敏原去除的影响。

目的：花粉可能会通过户外活动中被污染的衣服传播到室内。这项研究旨在评估机械干燥机的花粉去除功效。方法：棉制衣服用作衣物，尺寸为2×5厘米的织物用作测试样品。花粉均匀地分布在测试织物上。然后将织物固定在布料上，放置8小时以模仿现实生活条件。该实验在湿（洗衣服后）和干（不洗）两个条件下进行。干燥后，我们在测试织物上计数花粉，以评估花粉去除率。机械干燥后，我们测量了污染织物提取物中的残留过敏原。使用2-位点ELISA检测每种提取溶液中的过敏原浓度（Amb a 1，Bet v 1，Crp j 1和Phl p 1）。结果：对于豚草，雪松，桦木和太白草，干样品的平均花粉去除率分别为99.88±0.09％，99.96±0.03％，99.89±0.02％和99.82±0.11％。样本分别为98.83±0.87％，97.91±1.81％，97.29±1.19％和96.3±0.92％。此外，对于花粉变应原Amb a 1 [豚草]，Crp j 1 [日本雪松]，Bet v 1 [桦树]和Phl p 1 [太白草]，干燥样品的平均花粉变应原去除率为99.81±分别为0.06％，99.94±0.23％，99.90±0.11％和99.84±0.17％，湿样品的分别为98.11±0.14％，96.04±1.52％，97.21±0.83％和95.23±0.92％ 。每个物种没有统计学上的显着差异。结论：机械干燥可有效去除干湿织物上的花粉和过敏原。我们希望对去除其他室内过敏原的进一步研究将有助于改善过敏患者的环境控制。
