Effect of Electrolyzed Water on Washing
alkaline ionized liquid
acid ionized liquid
The detergency, that is the effect on removal of particle soil, on soiling prevention and on deodorization etc., of the electrolyzed water was compared with that of the pure water. The electrolyzed water, i.e. the alkaline ion liquid and the acid ion liquid, was produced using an electricity resolution production device. The wet artificially soiled cloths were washed at 40? in each liquid for 10 minutes by a Terg-O-tometer. Sodium dodecyl sulfate (SDS) was used as detergent. The removal efficiency of carbon black was demanded by applying an expression of Kubelka-Munk on the basis of the surface reflection rates of the test cloths. The soiling rates of the test pieces of white polyester were calculated on the surface reflection rates after they were washed with the wet artificially soiled cloths. The smoke of a cigarette (tar 12 mg, nicotine 1.0 mg) was absorbed by the test cloths of wool muslin in a glass container sealed up for 24 hours, and they were washed only with water afterwards. The stench of the specimens was measured with a smell meter, and the deodorant efficiency of the stench was calculated afterwards. The detergency was all good in order of the alkaline ion liquid, the pure water, the acid ion liquid. The property of dispersing solid particles of each liquid was dependent on the ingredients included in each liquid, the pH of the liquid and the hardness of water. The power of dispersing particles of the alkaline ion liquid was the biggest in three kinds of liquids used.
