For example, laundry on a clothes line will dry (by evaporation) more rapidly on a windy day than on a still day. Three key parts to evaporation are heat, atmospheric pressure (determines the percent humidity), and air movement. On a molecular level, there is no strict boundary between the liquid state and the vapor state.
Water is a better conductor of heat than air, thus if clothes are damp — because of sweat, rain, or immersion — water replaces some or all of the air between the fibres of the clothing, causing thermal loss through conduction and/or evaporation. Thermal insulation is thus optimal with three layers of clothing:
Laundry hung on a clothes line in a drying room (dehumidifier in the background and duct for ventilation in the ceiling) Drying is a mass transfer process consisting of the removal of water or another solvent [1] by evaporation from a solid, semi-solid or liquid. This process is often used as a final production step before selling or packaging ...
“Clothing with high thermal insulation keeps you warm by trapping heat inside it,” says Shaker, who has researched the subject, “while wind resistance helps block wind and protect from its ...
“As your body heats up, your body heat will cause evaporation of the water in your clothes, and so that just takes more heat from your body and makes you more likely to have more chills if your ...
Due to body heat and moisture there is almost always higher heat and humidity inside a clothing system. This creates a differential pressure forcing the heat and humidity toward the outside. The greater the difference between the heat and humidity inside the clothing system and the outside, the greater the Differential Pressure to push that ...
A clothes line, also spelled clothesline, also known as a wash line, is a device for hanging clothes on for the purpose of drying or airing out the articles. It is made of any type of rope , cord, wire, or twine that has been stretched between two points (e.g. two posts), outdoors or indoors, above ground level.
[11] [2] In hot-humid conditions, clothing can impede efficient evaporation. [3] In such environments, it helps to wear light clothing such as cotton, that is pervious to sweat but impervious to radiant heat from the sun. This minimizes the gaining of radiant heat, while allowing as much evaporation to occur as the environment will allow.
