Study on Washing of Clothes by Thermal Foam Prewashing
Firstly,this paper introduces and analyzes the washing habits of consumers.Secondly,the basic principle of hot foam pre-washing is expounded,and then three kinds of standard contaminated cloths are pre-washed respectively from the test.At the same time,the contaminated cloth after pre-washing is washed by the drum washing machine,and the cleaning rate of the contaminated cloth is determined using a whiteness meter.It is shown that adding pre-washing before washing has a more significant effect on removing clothes stains.In order to further study and confirm the effect of hot foam pre-washing,we used a variety of pre-washing methods with a variety of detergents through the orthogonal test method to pre-wash 3 kinds of standard contaminated cloth and then washed and ed the cleaning rate.The cleaning of hot foam pre-washing is better than other pre-washing methods,and the optimal parameter combination is provided.
