The area where the tenters were erected was wallpaper known as a tenterground. Scouring edit In Roman times, fulling was conducted by slaves working the cloth while ankle deep in tubs of human urine. Urine was so important to the fulling business that it was taxed. Stale urine, known as wash, was a source of ammonium salts and assisted in cleansing and whitening the cloth. By the medieval period, fuller's earth had been introduced for use in the process. This is a soft clay-like material occurring naturally as an impure hydrous aluminium silicate. It was used in conjunction with wash.
Fulling, also known as tucking or walking (spelt waulking in, scotland is a step in woollen clothmaking which involves the cleansing of cloth (particularly wool ) to eliminate oils, dirt, and other impurities, and making it thicker. The worker who does the job is a fuller, tucker, or walker, 1 all of which have become common surnames. Welsh word for a fulling mill is pandy, which appears in many place-names, for example. Tonypandy fulling mill lea. Contents, process edit, fulling involves two processes, scouring and milling (thickening). Originally, fulling was carried out by the pounding of the woollen cloth with a club, or the fuller's feet or hands. Scottish gaelic tradition, this process was accompanied by waulking songs, which women sang to set the pace. From the medieval period, however, fulling was often carried out in a water mill, followed by stretching the cloth on great frames known as tenters, to which it is attached by tenterhooks. It is from this process that the phrase being on tenterhooks is derived, as meaning to be held in suspense.

This summarises some of the scientific research undertaken. 11 Dyson (creators of the dyson Airblade dryer) have countered the claims presented, suggesting that the results were intentionally falsified. 12 Many people object to the loud noise that hand dryers make. Typically, installed hand dryers make over 80 decibels of sound at a distance of 10 ft (3.0 m) while in thank operation. 13 william Reception edit research conducted in 2008 indicated that European consumers much prefer hand towels over hand dryers in public washrooms. 63 of respondents said paper towels were their preferred drying method, while just 28 preferred a hand dryer. Respondents overwhelmingly considered paper towels to offer faster hand drying than electric hand dryers (68 vs 14). On the whole they also considered paper towels to be the most hygienic form of hand drying in public washrooms (53 vs 44). 14 History edit The earliest hand dryer was patented in 1921.
5, it found that after washing and drying hands with the warm air dryer, the total number of bacteria was found to increase on marathi average on the finger pads by 194 and on the palms by 254; drying with the jet air dryer resulted. 5 The scientists also carried out tests to establish whether there was the potential for cross contamination of other washroom users and the washroom environment as a result of each type of drying method. They found that: the jet air dryer, which blows air out of the unit at claimed speeds of 400 mph (640 km/h was capable of blowing micro-organisms from the hands and the unit and potentially contaminating other washroom users and the washroom environment up to 2 metres. In 2005, in a study conducted by tüv produkt und Umwelt, different hand drying methods were evaluated. 6 The following changes in the bacterial count after drying the hands were observed: Drying method Effect on Bacterial count Paper towels and roll Decrease of 24 Hot-air dryer Increase of 117 Another paper found that air dryers dispersed specify marker bacteria in a radius. 7 Another study found that hot air dryers had the capacity to increase the bacterial count on the skin, and that paper towel drying decreased skin bacterial count. 8 This is corroborated by another study which found that the mechanical action of paper towel drying removed bacteria, something air dryers cannot. 9 Doctors at the University of Ottawa claim that "the blowing of warm air may lead to an accelerated dehydration of the skin surface, thereby affecting the viability" of the microorganisms, and that the warm air may "penetrate all the crevices in the skin, whereas. 10 The european Tissue symposium, a trade body, has produced a position statement on the hygiene standards of different hand drying systems.
and divide it by the number of drys the hand dryer is capable of performing back to back in 1 hour. The world's lowest energy hand dryer uses just 1 watt-hour per dry and is rated.24 kW. Effect on environment edit, due to the reduction in litter and waste in comparison with paper towels, which cannot be recycled, 1 hand dryers are claimed to be better for the environment. Another study shows that whereas the majority of the environmental impact of a hand dryer occurs during its use, the environmental impact of paper towels is predominantly in the material production and manufacturing stages. 2, it is estimated that hand dryers use 5 less energy than paper towels in the first year, and 20 less over five years. A world Dryer study of 102 hand dryers installed in public schools in Topeka, kansas, claimed an annual savings.5 tons of solid waste, 690,000 gallons of water, and 587 trees; another World Dryer study of 153 hand dryers in the iowa state capitol. 3, however, a dutch study published in March 1995 indicated that there was environmental parity between hand dryers and paper towels as hand drying methods when all factors were taken into consideration. 4, hygiene edit, in 2009 a published study was conducted by the.

They may either operate with the push of a button or automatically using a sensor. Hand washing is an important part of hygiene, and so an effective method of drying the hands is necessary. Contents, hand dryers have been popular with industries for their apparent economies. According to manufacturers, hand dryers can cut costs by as much.5 (for example a company may spend 2340.00 per year on paper towels, where as the hand dryer expenditure would be as low.00 per year - this will vary good according. They require very little maintenance compared to paper towels, which must be replaced. An added benefit is the removal of the paper waste. Hand dryers represent a larger initial investment, so those responsible for facility management must do a careful cost analysis to determine whether they are cost effective in their building.
