その後、水道水による流水濯ぎを約１分間行い、二層式洗濯機で脱水した後、アイロンプレス（１８０℃、３０秒）で乾燥した。
洗浄前後の汚染布の反射率及び原布（汚染前の布)の反射率を、Spectro Color Meter SE2000 （日本電色工業株式会社製）を用いてλ＝４６０ｎｍにて測定し、下式により洗浄率を算出した。
洗浄率（％）＝［（Ｒｂ−Ｒａ）／（Ｒｏ−Ｒａ）］×１００
Ｒａ：洗浄前の反射率
Ｒｂ：洗浄後の反射率
Ｒｏ：原布（汚染前の布)の反射率
(Detergency evaluation method)
Into a 200 mL glass beaker, add 0.2 L of 4 ° DH hard water (Ca / Mg = 8/2) and 1 g of powder washing pretreatment composition, and add a magnetic stirrer and a stirrer 8 mm in diameter and 20 mm in length. It was dissolved by stirring at 200 rpm for 5 minutes to prepare a treatment solution. Four sheets of model stool-contaminated cloth were put into this and left for 30 minutes. The temperature of the treatment liquid was 25 ° C. at the start of the soaking. Further, the ratio of the amount of the processing liquid (L) / the mass (kg) of the model stool-contaminated cloth was 50.
Thereafter, a standard concentration solution (0.67 g / liter) of a commercially available liquid detergent [Liquid Big (non-fluorescent, manufactured by Kao Professional Service Co., Ltd.)] prepared in a stainless beaker of Terg-O-tometr (manufactured by Ueshima Seisakusho Co., Ltd.) (L, 25 ° C.) 1 L was taken out from the soaking bath, and a model stool-contaminated cloth with squeezed water was put in and washed with Terg-O-tometr at 85 rpm for 10 minutes.
Then, running water was rinsed with tap water for about 1 minute, dehydrated with a two-layer washing machine, and then dried with an iron press (180 ° C., 30 seconds).
Measure the reflectance of the contaminated fabric before and after cleaning and the reflectance of the fabric (pre-contaminated fabric) at λ = 460 nm using a Spectro Color Meter SE2000 (manufactured by Nippon Denshoku Industries Co., Ltd.). The rate was calculated.
Washing rate (%) = [(R b −R a ) / (R o −R a )] × 100
R a : reflectivity before cleaning R b : reflectivity after cleaning R o : reflectivity of raw fabric (cloth before contamination)
