The fibers for controlling harmful arthropods were subjected to a wash resistance test by the following method.

[0024] (Washing durability test) 1. A cleaning solution was prepared by mixing 40 mL of JAFET standard detergent and 30 L of water. 2. The fiber for controlling harmful arthropods and 300 mL of the cleaning solution were added to a 500 mL beaker, and the mixture was stirred for 30 minutes using a butterfly-shaped stirring blade. 3. The fiber for controlling harmful arthropods was taken out and dehydrated by sandwiching it between paper rags. 4. The dehydrated pest arthropod control fiber and 300 mL of water were placed in a separate 500 mL beaker and stirred with a butterfly-shaped stirring impeller for 30 minutes. 5. The above steps 1 to 4 were repeated twice and then air-dried.

[0025] For various pest control fibers, the content of the insect repellent component in the fiber was measured before and after the washing durability test, and the residual rate was calculated according to the following formula (1).
