Abstract
To study the effect of a washing machine with silver nano technology on its detergency, the discoloring of the dyed clothes and the staining of standards adjacent fabrics were examined. As the laundry specimen, cotton fabric dyed with reactive dyes and Polyester fabric dyed with disperse dyes were chosen; and as the adjacent fabrics, undyed cotton. polyester and nylon fabrics were chosen. The colorfastness was evaluated after washing under conditions that those washing temperature, liquor ratio, detergency concentration and the type of water were varied. When the clothes were washed with the tap water contains silver ion, the deposition of silver compounds into the washed clothes was measured. As a results, after the washing in the various conditions, discoloring of the dyed clothes was not intense. The higher the washing temperature and the lower the liquor ratio, the larger the staining appeared on the white fabrics; especially for the white nylon fabrics. The concentration of detergent and the type of water affected hardly the colorfastness. After the repeated washing with the water contains silver, whiteness of the cotton and the nylon fabrics were lower than the result after the washing with the tap water, and a quantity of silver ions was found on the washed clothes.
