Airing (air Circulation)
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. Reasons 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grating
A grating is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets, in which case the second set is usually perpendicular to the first (as illustrated). When the two sets are perpendicular, this is also known as a wikt:grid (as in grid paper) or a mesh. As filters A grating covering a drain (as illustrated) can be a collection of iron bars (the identical, elongated elements) held together (to ensure the bars are parallel and regularly spaced) by a lighter iron frame. Gratings over drains and air vents are used as filters, to block movement of large solids (e.g. people) and to allow movement of liquids. A register is a type of grating used in heating, ventilation, and air conditioning, which transmits air, while stopping solid objects.

Textiles
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: Domestic purposes onsumer textilesand technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, but in technical textiles, functional properties are the priority. Geotextiles, industrial textiles, medical textiles, and many other areas are examples of technical textiles, whereas clothing a ...

Microbial Growth And Nutrition
A microorganism, or microbe,, ''mikros'', "small") and ''organism'' from the el, ὀργανισμός, ''organismós'', "organism"). It is usually written as a single word but is sometimes hyphenated (''micro-organism''), especially in older texts. The informal synonym ''microbe'' () comes from μικρός, mikrós, "small" and βίος, bíos, "life". is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax. Because m ...

Humidity And Hygrometry
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waste Heat
Waste heat is heat that is produced by a machine, or other process that uses energy, as a byproduct of doing work. All such processes give off some waste heat as a fundamental result of the laws of thermodynamics. Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the original energy source. Sources of waste heat include all manner of human activities, natural systems, and all organisms, for example, incandescent light bulbs get hot, a refrigerator warms the room air, a building gets hot during peak hours, an internal combustion engine generates high-temperature exhaust gases, and electronic components get warm when in operation. Instead of being "wasted" by release into the ambient environment, sometimes waste heat (or cold) can be used by another process (such as using hot engine coolant to heat a vehicle), or a portion of heat that would otherwise be wasted can be reused in the same process if make-up heat is added to the ...

Airing Cupboard
A cupboard is a piece of furniture for enclosing dishware or grocery items that are stored in a home. The term gradually evolved from its original meaning: an open-shelved side table for displaying dishware, more specifically plates, cups and saucers. These open cupboards typically had between one and three display tiers, and at the time, a drawer or multiple drawers fitted to them.Andrews, John (2006) ''British Antique Furniture''. Antique Collectors' Club ; p. 226 Types of cupboards Airing cupboard An airing cupboard (or hot press) is a built-in storage space, sometimes of walk-in dimensions, containing a water heater, either an immersion heater for hot running water or a boiler for central heating water (hence, also "boiler cupboard"), or a hot water storage tank. Shelves, usually slatted to allow for circulation of heat, are positioned above or around the heater to provide room for clothing. The purpose is to allow air to circulate around the stored fabrics to prevent dam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanging Locker
Hanging is the suspension of a person by a noose or ligature around the neck.Oxford English Dictionary, 2nd ed. Hanging as method of execution is unknown, as method of suicide from 1325. The ''Oxford English Dictionary'' states that hanging in this sense is "specifically to put to death by suspension by the neck", though it formerly also referred to crucifixion and death by impalement in which the body would remain "hanging". Hanging has been a common method of capital punishment since medieval times, and is the primary execution method in numerous countries and regions. The first known account of execution by hanging was in Homer's ''Odyssey'' (Book XXII). In this specialised meaning of the common word ''hang'', the past and past participle is ''hanged'' instead of ''hung''. Hanging is a common method of suicide in which a person applies a ligature to the neck and brings about unconsciousness and then death by suspension or partial suspension.

Drying Cabinet
A drying cabinet is today usually an electrical machine designed to expedite the drying of items - usually clothing - that are unsuitable for a mechanical clothes dryer. Such items may include delicate clothing care labeled as "hang dry", "dry flat" or "do not tumble dry" on their wash instructions, as well as items such as comforters, boots and coats. History In both Europe and America, wealthier and commercial properties sometimes had drying cabinets or drying rooms associated with their laundry rooms. The cabinets were of wood or cast iron, with a series of drying racks on wheels which were pulled in or out of the cabinet horizontally. The cabinet was heated by coal, gas or wood. The Shaker community still uses these cabinets. See also Airing Cupboard. However these cabinets and cupboards were intended for the general drying of laundry, whereas the modern cabinets are usually intended for items of clothing unsuitable for a traditional clothes dryer. Europe Since the 1980s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Futon Dryer
A is an electric device that warms and dries a Japanese ''futon'' by forcing warm air through it. Mechanism A ''futon'' dryer works by drawing in air with an electric fan and heating it, and then forcing it into a large cloth pouch. The pouch is usually inserted between the futon mattress and comforter, and hot air is forced through it for about an hour to dry the ''futon''. ''Futon'' dryers run on a timer, and when the timer reaches zero, cold air is blown before the unit shuts off. A ''futon'' drier uses about 600 watts of electricity, about the same as a hair dryer. Purpose A ''futon'' must be kept dry because human sweat and body heat create a warm, moist environment which is amenable to mites. Traditionally ''futon'' are kept dry by hanging them out on a balcony in the sun to dry in the open air, but some people are too busy to do this since they must be hung during daylight hours and brought in before sunset, when the temperature drops and moisture condenses inside t ...

Overhead Clothes Airer
An overhead clothes airer, also known variously as a ceiling clothes airer, laundry airer, pulley airer, laundry rack, laundry pulley, or a Sheila Maid, is a ceiling-mounted mechanism to dry clothes. In the North of England it is often known as a creel, in Scotland as a pulley, and in United States as a Sheila Maid. History Overhead clothes airers were often installed, from the late eighteenth century onwards, in the laundry room of large houses and estates in Europe. Originally made by the estate handyman, by the middle of the 19th century they almost always benefited from a rope and pulley system to raise and lower the rack, and such systems began to be manufactured and sold commercially, both in Europe and America. Larger, wealthier or commercial properties sometimes had drying cabinets or drying rooms associated with their laundry rooms, in addition to or instead of clothes airers. The cabinets were of wood or cast iron, with a series of drying racks on wheels which were pulled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clothesline
A clothes line or washing line is any type of rope, cord, or twine that has been stretched between two points (e.g. two sticks), outside or indoors, above the level of the ground. Clothing that has recently been washed is hung along the line to dry, using clothes pegs or clothespins. Washing lines are attached either from a post or a wall, and are frequently located in back gardens, or on balconies. Longer washing lines often have props holding up sections in the middle due to the weight of the usually wet clothing. More elaborate rotary washing lines save space and are typically retractable and square or triangular in shape, with multiple lines being used (such as the Hills Hoist from Australia). Some can be folded up when not in use (although there is a very minor hazard of getting fingers caught, so there is usually a safety button). In Scotland, many tenement buildings have a "drying green", which is a communal area predominantly used for clothes lines – it may also be u ...
