Grassing (textiles)
Grassing is one of the oldest methods of bleaching textile goods. The grassing method has been long been used in Europe to bleach linen and cotton based fabrics. Method The linens were laid out on the grass for over seven days after boiling with the ''lyes of ashes and rinsing''. The atmospheric oxygen and the oxygen left by the grass provide the whitening action. The cloth becomes whiter day by day until it attains the full whiteness. It was a slow process, but safer for the subjected material. Chemical bleaching may harm the cloth , but in the grassing it hardly affects the cloth's strength. Bleachfield The Bleachfield was an open area to spread cloth. It was a field near the watercourse used by a bleachery. Bleachfields were common in and around the mill towns during the British Industrial Revolution Chemical bleaching With the discovery of Chlorine in the late 18th century, chemical bleaching took over from grassin, as it was quicker and could be done in indoors.

Conjugated System
In theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability. It is conventionally represented as having alternating single and multiple bonds. Lone pairs, radicals or carbenium ions may be part of the system, which may be cyclic, acyclic, linear or mixed. The term "conjugated" was coined in 1899 by the German chemist Johannes Thiele. Conjugation is the overlap of one p-orbital with another across an adjacent σ bond (in transition metals, d-orbitals can be involved). A conjugated system has a region of overlapping p-orbitals, bridging the interjacent locations that simple diagrams illustrate as not having a π bond. They allow a delocalization of π electrons across all the adjacent aligned p-orbitals. The π electrons do not belong to a single bond or atom, but rather to a group of atoms. Molecules containing conjugated syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textile Arts
Textile arts are arts and crafts that use plant, animal, or synthetic fibers to construct practical or decorative objects. Textiles have been a fundamental part of human life since the beginning of civilization. The methods and materials used to make them have expanded enormously, while the functions of textiles have remained the same, there are many functions for textiles. Whether it be clothing or something decorative for the house/shelter. The history of textile arts is also the history of international trade. Tyrian purple dye was an important trade good in the ancient Mediterranean. The Silk Road brought Chinese silk to India, Africa, and Europe, and, conversely, Sogdian silk to China. Tastes for imported luxury fabrics led to sumptuary laws during the Middle Ages and Renaissance. The Industrial Revolution was shaped largely by innovation in textiles technology: the cotton gin, the spinning jenny, and the power loom mechanized production and led to the Luddite rebel ...

History Of The Textile Industry
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Scouring (textiles)
Scouring is a preparatory treatment of certain textile materials. Scouring removes soluble and insoluble impurities found in textiles as natural, added and adventitious impurities, for example, oils, waxes, fats, vegetable matter, as well as dirt. Removing these contaminants through scouring prepares the textiles for subsequent processes such as bleaching and dyeing. Though a general term, "scouring" is most often used for wool. In cotton, it is synonymously called "boiling out," and in silk, and "boiling off." Purpose of scouring Scouring is an essential pre-treatment for the subsequent finishing stages that include bleaching, dyeing, and printing. Raw and unfinished textiles contain a significant amount of impurities, both natural and foreign. It is necessary to eliminate these impurities to make the products ready for later steps in textile manufacturing. For instance, fatty substances and waxy matters are the major barriers in the hydrophilicity of the natural fibers. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Covalent Bond
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full valence shell, corresponding to a stable electronic configuration. In organic chemistry, covalent bonding is much more common than ionic bonding. Covalent bonding also includes many kinds of interactions, including σ-bonding, π-bonding, metal-to-metal bonding, agostic interactions, bent bonds, three-center two-electron bonds and three-center four-electron bonds. The term ''covalent bond'' dates from 1939. The prefix ''co-'' means ''jointly, associated in action, partnered to a lesser degree, '' etc.; thus a "co-valent bond", in essence, means that the atoms share " valence", such a ...

Hydrogen Peroxide
Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use, and in higher concentrations for industrial use. Concentrated hydrogen peroxide, or " high-test peroxide", decomposes explosively when heated and has been used as a propellant in rocketry. Hydrogen peroxide is a reactive oxygen species and the simplest peroxide, a compound having an oxygen–oxygen single bond. It decomposes slowly when exposed to light, and rapidly in the presence of organic or reactive compounds. It is typically stored with a stabilizer in a weakly acidic solution in a dark bottle to block light. Hydrogen peroxide is found in biological systems including the human body. Enzymes that use or decompose hydrogen peroxide are classified as peroxidases. Properties The boiling poi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorine
Chlorine is a chemical element with the Symbol (chemistry), symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Electronegativity#Pauling electronegativity, Pauling scale, behind only oxygen and fluorine. Chlorine played an important role in the experiments conducted by medieval Alchemy, alchemists, which commonly involved the heating of chloride Salt (chemistry), salts like ammonium chloride (sal ammoniac) and sodium chloride (common salt), producing various chemical substances containing chlorine such as hydrogen chloride, mercury(II) chloride (corrosive sublimate), and hydrochloric acid (in the form of ).

Textile Bleaching
The textile bleaching (or bleaching of textiles) is one of the steps in the textile manufacturing process. The objective of bleaching is to remove the natural color for the following steps such as dyeing or printing or to achieve full white. All raw textile materials, when they are in natural form, are known as ' greige' material. They have their natural color, odor and impurities that are not suited to clothing materials. Not only the natural impurities will remain in the greige material, but also the add-ons that were made during its cultivation, growth and manufacture in the form of pesticides, fungicides, worm killers, sizes, lubricants, etc. The removal of these natural coloring matters and add-ons during the previous state of manufacturing is called scouring and bleaching. A continuous bleaching range is a set of machines to carry out bleaching action. It consists of several compartments in which fabric moves from one side to another with the help of guide rollers an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textile Manufacture During The British Industrial Revolution
Textile manufacture during the British Industrial Revolution was centred in south Lancashire and the towns on both sides of the Pennines in the United Kingdom. The main drivers of the Industrial Revolution were textile manufacturing, iron founding, steam power, oil drilling, the discovery of electricity and its many industrial applications, the telegraph and many others. Railroads, steam boats, the telegraph and other innovations massively increased worker productivity and raised standards of living by greatly reducing time spent during travel, transportation and communications.. Before the 18th century, the manufacture of cloth was performed by individual workers, in the premises in which they lived and goods were transported around the country by packhorses or by river navigations and contour-following canals that had been constructed in the early 18th century. In the mid-18th century, artisans were inventing ways to become more productive. Silk, wool, and linen fabrics were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mill Town
A mill town, also known as factory town or mill village, is typically a settlement that developed around one or more mills or factories, usually cotton mills or factories producing textiles. Europe Italy * ''Crespi d'Adda'', UNESCO World Heritage Site * ''Nuovo quartiere operaio'' in Schio * ''Villaggio Leumann'' a Collegno * ''Villaggio Frua'' in Saronno * ''Villaggio operaio della Filatura'' in Tollegno Poland Żyrardów The town grew out of a textile factory founded in 1833 by the sons of Feliks Lubienski, who owned the land where it was built. They brought in a specialist from France and his newly designed machines. He was French inventor, Philippe de Girard from Lourmarin. He became a director of the firm. The factory town developed during the 19th century into a significant textile mill town in Poland. In honour of Girard, 'Ruda Guzowska' as the original estate was called, was renamed Żyrardów, a toponym derived of the polonised spelling of Girard's name. Most of ...
