Why does laundry dry?

A clear explanation of the basic knowledge necessary to understand distillation, distillation towers, and distillation devices!

Kansai Chemical conducts plant engineering for processes such as distillation, evaporation, refining, reaction, fermentation, extraction, and solvent recovery. I will explain the "mechanism of how laundry dries." On rainy days during the rainy season, laundry is difficult to dry. On sunny summer days, it dries easily. This is due to the difference in the amount of moisture in the air (humidity). However, the total number of air molecules (the amount of air) and water molecules (the amount of moisture) in the atmosphere is almost equal. The number of water molecules in the atmosphere increases with higher temperatures, and as the number of water molecules increases, the number of air molecules decreases. There is a limit to the number of water molecules that can exist. On winter mornings, you may see water droplets on the window glass. This happens because the room temperature has risen due to heating at night, allowing it to hold a lot of moisture. When morning comes and the temperature drops, it exceeds that limit, resulting in water droplets. During such times, laundry does not dry. *For more details, please refer to the PDF document or feel free to contact us.*
