  • ⁇ Evaluation method for detergency> Preparation of artificial mud-contaminated cloth
  • the model-contaminated cloth used for evaluation was prepared by the following procedure. Since this method adheres particles between fibers by re-staining, the soiled cloth is more difficult to remove than a normal soiled cloth with mud applied to the surface.
  • the mud used was Kanuma gardening Akadama soil dried at 120° C. ⁇ 5° C. for 4 hours, pulverized and sieved through a 75 ⁇ m sieve before use. 6 g of mud was added to 1000 mL of ion-exchanged water, stirred, and then subjected to ultrasonic waves for 15 minutes.
  • the cleaning rate is 45% or more.
  • the reflectance before or after washing is the reflectance measured on the artificial sludge contaminated cloth before or after washing, respectively.
  • Cleaning rate (%) 100 x [(reflectance after cleaning-reflectance before cleaning)/(reflectance of raw fabric-reflectance before cleaning)]
