纺织品中驱避剂艾草油和氯菊酯含量对驱蚊耐久性影响

Effect of the content of repellent wormwood oil and permethrin on mosquito repellent durability in textiles

采用气相色谱/质谱联用法对驱蚊纺织品中所含杀虫剂氯菊酯和驱避剂艾草油的含量以及对应条件下的驱避等级进行了研究,建立了纺织品中这两种常用驱蚊剂含量与驱蚊效果的关系。结果表明:当艾草油及氯菊酯质量浓度超过500 mg/L时,随着浓度的增加,对蚊虫的驱避率不断提升;经水洗、自然放置和模拟人体穿着后,艾草油主要成分损失率为90%~95%,氯菊酯损失率为10%~40%。

The content of the repellent wormwood oil and permethrin contained in mosquito repellent textiles by gas chromatography/mass spectrometry and the repellent level under the corresponding conditions were studied. The relationship between the content of these two common insect repellent agents in textiles and the mosquito repellent effect was established. The results showed that when the concentration of wormwood oil and permethrin reached more than 500 mg/L, with the increase of concentration, the repelling rate increased continuously. After washing, natural placement, and simulated human body wearing, the main component content of wormwood oil was lost in the range of 90%~95%, and the permethrin content loss was 10%~ 40%.
