Assess The Whiteness Of Clothes Used In Hotels And Hospitals

Responsive image

In hotels and hospitals, white color is the best and preferred color used for linens, towels, and sheets because it is directly associated with the cleanliness and freshness. There is no standard provided for preference of shade in white color as its all depend on the perception & taste of the users. Frequent usage and exposure of the white cloth and then to the chemical at the time of cleaning and washing can affect the whiteness of the linen cloths and turn it to yellowish color which looks unhygienic and dirty. The lack of assessing the whiteness of linen forces the users to reject the material before the ends of its actual life which unnecessarily leads to incurring the purchasing cost by replacing it. Grading the white color by visual assessment is entirely useless because different conditions of lights and eye fatigue will affect the results.
