Abstract: With the improvement of people’s living standards, the development of functional textiles has become a research hotspot. Anti-mosquito textiles can help people avoid mosquito bites and disease transmission. The paper researched the application of the finishing process of the anti-mosquito agent EULAN SPA 01 on cotton twill and polyester plain fabric, and measured the permethrin content in antimosquito fabric via high performance gas chromatography. The result indicated the best anti-mosquito finishing process: using the anti-mosquito cross-linking agent TANA PUR ONE 40 g/L at 140 ℃ curing temperature for 1 minute. After 10 standard washing of the anti-mosquito fabric, its permethrin content remained at 80% or so, which maintained excellent anti-mosquito effect and washing fastness.
