Hassas kumaşların ev tipi çamaşır makinelerinde yıkanması için yenilikçi bir ıslak yıkama algoritması tasarımı

From ancient times, cleaning has been an essential requirement and various developments have been achieved until today. Besides daily used garments, delicate garments produced from silk and wool; as well as leather products are popular. These delicate garments demand special care; i.e. washing in specialized machines with novel techniques to prevent inevitable harms which occur when delicate garments are laundered in a home type washing machine. This risk can be minimized with dry cleaning technique in which a hazardous petroluem-based solvent, namely perchloroethylene, is widely used. This common solvent has many side effects including carcinogenic effects on human health and detrimental wastes which are one of the main causes of environmental contamination. Environmental Protection Agency, a foundation, has limited the usage of perchloroethylene and pronounced that using perchloroethylene in dry cleaning will not be continued as of 2023. This limitation brings out a need for a novel environmental friendly cleaning technique without the use of solvents, and the best alternative offered so far appears to be wet cleaning. In wet cleaning, water and biodegradable detergents are used. Thus, wet cleaning process provides an environmental friendly and harmless cleaning technique for human health. There are some commercial wet cleaning applications which attracted attention, however, a non-commercial application is yet missing.The objective of the study is to design an algorithm to launder delicate fabrics in home-type washing machines with a newly designed wet cleaning algorithm for minimum shrinkage with acceptable color loss. To achieve this, different levels of washing parameters in wet cleaning technique are taken into consideration. These parameters are water amount, mechanical action during laundering (ED) and number of rinsings whose levels are selected to design different washing algorithms. Shrinkage, color loss, rinsing performance, washing performance and mechanical action performance of algorithms are determined with aforementioned algorithms with silk fabrics and other standard test references. The effects of selected parameters on shrinkage, color loss, rinsing performance, washing performance and mechanical action performance are investigated with Minitab® ANOVA analysis. Finally, the parameters, with no or minimum adverse effect on delicate garments, are chosen and two alternative novel washing algorithms possessing these parameters are proposed.
