Steaming Process In Lancashire Cotton Mills
Steaming or artificial humidity was the process of injecting steam from boilers into cotton weaving sheds in Lancashire, England, in the late 19th and early 20th centuries. The intention was to prevent breakages in short-staple Indian Surat cotton which was introduced in 1862 during a blockade of American cotton at the time of the American Civil War. There was considerable concern about the health implications of steaming. Believed to cause ill health, this practice became the subject of much campaigning and investigation from the 1880s to the 1920s. A number of Acts of Parliament imposed modifications. Background Warp yarns were strengthened by the addition of size – a substance made from flour and tallow or china clay. High humidity was required to weave sized yarn and to minimise the size dust in the air. This was especially important when cloth companies were forced to use Indian Surat cotton instead of Sea Island cotton from South Carolina in 1862 during the American Ci ...

Weaving Shed
A weaving shed is a distinctive type of mill developed in the early 1800s in Lancashire, :Derbyshire and Yorkshire to accommodate the new power looms weaving cotton, silk, woollen and worsted. A weaving shed can be a stand-alone mill, or a component of a combined mill. Power looms cause severe vibrations requiring them to be located on a solid ground floor. In the case of cotton, the weaving shed needs to remain moist. Maximum daylight is achieved, by the sawtooth "north-facing roof lights". History The early textile trade relied on domestic outworking. Handloom weavers would take the yarn to their cottage loom shops, and return the completed fabric to the mill. Reliable power looms that could be worked from an overhead line shaft were not available before Kenworthy and Bulloughs weft stop motion, the roller temple and the loose reed which appeared in the 1840s. The first weaving floors were on the ground floor of the existing narrow mills, where the workpiece was lit by tal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four Loom Weaver
Four Loom Weaver (Roud 1460), probably derived from "The Poor Cotton Weaver" is a 19th-century English lament on starvation. One source also names it Jone o Grinfilt though this title usually refers to different lyrics and score, which is about the naiveté of country folk. Actually, it is very similar to Jone o'Grinfilt Junior which can be found in John Harland's ''Ballads and Songs of Lancashire'' (1875 pp. 169–171). Jone o Grinfilt is believed to have been written by Joseph Lees of Glodwick, near Oldham in the 1790s. The earlier version, the Poor Cotton Weaver, was probably written before 1800, after the Napoleonic wars it was revived or re-written, due to economic hard times, when weavers were reduced to eating nettles. This could refer to the war itself any of the periodic economic downturns in the cotton industry. It was featured in Mary Barton published in 1848, then later referred to the Lancashire Cotton Famine of 1862. It is found on broadsides in Manch ...

Wet-bulb Temperature
The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked (water at ambient temperature) cloth (a wet-bulb thermometer) over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature ( dry-bulb temperature); at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling. The wet-bulb temperature is defined as the temperature of a parcel of air cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat supplied by the parcel. A wet-bulb thermometer indicates a temperature close to the true (thermodynamic) wet-bulb temperature. The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only. Even heat-adapted people cannot carry out normal outdoor activities past a wet-bulb temperature of , equivalent to a heat index of . The theo ...

Thermometer
A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer or the digital readout on an infrared model). Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research. History While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to approximate this clo ...

Psychrometer
A hair tension dial hygrometer with a nonlinear scale. A hygrometer is an instrument used to measure the amount of water vapor in air, in soil, or in confined spaces. Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity. Modern electronic devices use the temperature of condensation (called the dew point), or they sense changes in electrical capacitance or resistance to measure humidity differences. A crude hygrometer was invented by Leonardo da Vinci in 1480. Major leaps came forward during the 1600s; Francesco Folli invented a more practical version of the device, while Robert Hooke improved a number of meteorological devices including the hygrometer. A more modern version was created by Swiss polymath Johann Heinrich Lambert in 1755. Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Enfield Roscoe
Sir Henry Enfield Roscoe (7 January 1833 – 18 December 1915) was a British chemist. He is particularly noted for early work on vanadium, photochemical studies, and his assistance in creating Oxo (food), in its earlier liquid form. Life and work Henry Enfield Roscoe was born in London, the son of Henry Roscoe (1800–1836) and Maria Roscoe, née Fletcher (1798–1885), and grandson of William Roscoe (1753–1831). Stanley Jevons the Australian economist was a cousin. Roscoe studied at the Liverpool Institute for Boys and University College London. He then went to Heidelberg to work under Robert Bunsen, who became a lifelong friend. He also befriended William Dittmar. In 1857, Roscoe returned to England with Dittmar and was appointed to the chair of chemistry at Owens College, Manchester, with Dittmar as his assistant. In 1858 the state of the college was such that the ''Manchester Guardian'' called it "a mortifying failure". In the same year Roscoe was accoste ...

Royal Commission On Labour
The Royal Commission on Labour (or the Whitley Commission on Labour) was a Royal Commission set up in 1929 to investigate the working conditions on plantations in India. The commission The Commission was chaired by John Henry Whitley. The commission submitted its report in 1931. The report surprised many by concurring with the criticisms of Mahatma Gandhi Mohandas Karamchand Gandhi (; ; 2 October 1869 – 30 January 1948), popularly known as Mahatma Gandhi, was an Indian lawyer, Anti-colonial nationalism, anti-colonial nationalist Quote: "... marks Gandhi as a hybrid cosmopolitan figure ... and others that poverty was the cause of India's social and industrial problems. It was also critical of British employers' role in perpetuating the problems. The Royal Commission on Labour in 1931 pointed out the need for systematic collection of labour statistics. It observed that the policy must be built on facts as the uncertainty of facts would lead to confusion and confl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnley
Burnley () is a town and the administrative centre of the wider Borough of Burnley in Lancashire, England, with a 2001 population of 73,021.
