Airing
Airing is the practice of hanging or laying out articles and exposing them to air, and sometimes heat and light. This practice is commonly used to dry many types of fabric. One of the most common methods of drying using airing is the clothesline. It consists of a thin wire from which clothing pieces and bedsheets (among others) are hung, using pegs or simply laying the article over the line.
Air contains water vapour; warm air can hold more water than cold air. If the temperature of air drops past its dew point, the water will condense out. The dew point is the point where the relative humidity reaches 100%, and the air becomes supersaturated with water.
If water condenses on pieces of equipment, it can cause rot, mould, mildew, and other deterioration. To prevent this, they are brought out in the open, and undersaturated air is circulated around them to dry them out. Some extant mildew can be killed by airing for several hours before vacuuming the cloth.
In a building with forced-air heating, the air is brought in from the outside and warmed, so the indoor relative humidity is lowered. In cold weather, the relative humidity inside such a building will be very dry, and airing will not be as important. In warmer climates where heating is less-used, condensation is more likely to be a problem. As exhaled breath is at about 100% humidity, breathing in a room will encourage condensation.
A human body heats and humidifies clothing it is wearing. Airing clothing after wearing dries it out again.
Airing is used to reduce smells and allow clothing to be washed less frequently. Reduced microbial growth aside, a common source of smells is volatile organic compounds. As they are volatile, they will tend to evaporate into the air when articles are aired.
Airing outdoors is best done when the outdoor humidity is lower, often between 10:00 a.m. and 3:00 p.m., midmorning to midafternoon. Airing for a few hours will prolong the life of fabric, but airing for too long in strong light can damage it.
Clothing is often hung to air in a clothesline or clotheshorse, outdoors in dry weather, and indoors in wet. An overhead clothes airer may be used to save space.
