Shearing (textiles)
Shearing is a kind of mechanical finish in which the appearance of the fabric is enhanced by cutting the loops or raised surface to a uniform and even height. The machine may have a spiral blade similar to a grass cutting machine. A Shearing machine can cut the loop or the pile to a desired level. Shearing was most commonly used to make woolens and worsted materials. It was a part of dry finishing of woolen and worsted goods. Previously, shearing was also a component of gigging or napping; when partially produced goods were exposed to shear in order to improve the impact of gigging or napping, the process was referred to as "cropping." History Most of the Medieval clothing and textiles were processed and finished manually. The finishing of English Woolens includes shearing. Shearmen were skilled artisans who used to shear the fabric by hand. Shearman's job was to nap the cloth manually, using teasels and shears to trim the pile. A silky and smooth feeling was produced by the gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finishing (textiles)
In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing. The precise meaning depends on context. Fabric after leaving the loom or knitting machine is not readily useable. Called grey cloth at this stage, it contains natural and added impurities. Sometimes it is also processed at fiber or yarn stages of textile manufacturing. Grey fiber or yarn or fabric goes through a series of processes such as wet processing and finishing. Finishing is a broad range of physical and chemical treatments that complete one stage of textile manufacturing and may prepare for the next step, making the product more receptive to the next stage of manufacturing. Finishing adds value to the product and makes it more attractive, useful, and functional for the end-user. Improvi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aesthetics (textile)
Aesthetics in textiles is one of the basic concepts of serviceability of textiles. It is determined by the perception of touch and sight. Aesthetics imply the appearance and attraction of textile products; it includes the color and texture of the material. It is a statement about the end user (consumer) and the target market. When combined with fabric construction, the finish of the clothing material, garment fit, style, and fashion compatibility, colours create an aesthetic comfort. All of these elements work together to satisfy our visual perception. Aesthetics incorporates the role of evaluation (analysing and judging) also. There are various arts and applications that imparts aesthetic properties in textiles. Additionally, the use of LEDs and optical fibres enables the creation of aesthetic properties such as illuminated textiles. History From antiquity until the eighteenth century, the majority of textiles were crafted and decorated by hand. Human ingenuity and the u ...

Lawn Mower
A lawn mower (also known as a mower, grass cutter or lawnmower) is a device utilizing one or more revolving blades (or a reel) to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower, but generally is adjustable by the operator, typically by a single master lever, or by a lever or nut and bolt on each of the machine's wheels. The blades may be powered by manual force, with wheels mechanically connected to the cutting blades so that when the mower is pushed forward, the blades spin or the machine may have a battery-powered or plug-in electric motor. The most common self-contained power source for lawn mowers is a small (typically one cylinder) internal combustion engine. Smaller mowers often lack any form of propulsion, requiring human power to move over a surface; "walk-behind" mowers are self-propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self-propelled "walk-behind" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gig-mill
A gig-mill (gigging machine, napping machine) was type of raising machine that used teasels to produce a nap on cloth. Examples of the results of gigging are woolen fabrics such as chinchilla, beaver cloth, and melton. The process involved gradual teasing of the surface to raise the nap. Gigging Gigging was an old method of raising. As with flannelette, the fabric surface is treated with sharp teasels during ''Gigging'' to elevate the surface fibers, providing hairiness and lustrous nap. The fabric gets a soft feel. Teasels from a plant, a thistle-like species, were once used to make it. These were fixed to a cylinder. Later, teasels were replaced by metallic wires similar to those used in carding machines. Napped fabrics "Napping", "raising" and "gigging" are synonymous terms. Napping is the process of brushing for raising the nap. The raising method is used to draw out the ends of the fibers. Examples of napped fabrics include Brushed tricot, and Flannelette. Nap Nap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nap (fabric)
Primarily, nap is the raised (fuzzy) surface on certain kinds of cloth, such as velvet or moleskin. Nap can refer additionally to other surfaces that look like the surface of a napped cloth, such as the surface of a felt or beaver hat. Starting around the 14th century, the word referred originally to the roughness of woven cloth before it was sheared."nap". ''The Oxford English Dictionary''. 2nd ed. 1989. When cloth, especially woollen cloth, is woven, the surface of the cloth is not smooth, and this roughness is the nap. Generally the cloth is then "sheared" to create an even surface, and the nap is thus removed. A person who trimmed the surface of cloth with shears to remove any excess nap was known as a shearman. Piled nap Since the 15th century, the term ''nap'' has generally referred to a special pile given to the cloth. The term ''pile'' refers to raised fibres that are there on purpose, rather than as a by-product of producing the cloth. In this case, the nap is woven i ...

Early Medieval European Dress
Early medieval European dress, from about 400 AD to 1100 AD, changed very gradually. The main feature of the period was the meeting of late Roman costume with that of the invading peoples who moved into Europe over this period. For a period of several centuries, people in many countries dressed differently depending on whether they identified with the old Romanised population, or the new populations such as Franks, Anglo-Saxons, Visigoths. The most easily recognisable difference between the two groups was in male costume, where the invading peoples generally wore short tunics, with belts, and visible trousers, hose or leggings. The Romanised populations, and the Church, remained faithful to the longer tunics of Roman formal costume, coming below the knee, and often to the ankles. By the end of the period, these distinctions had finally disappeared, and Roman dress forms remained mainly as special styles of clothing for the clergy – the vestments that have changed relatively li ...

Woolen
Woolen (American English) or woollen (Commonwealth English) is a type of yarn made from carded wool. Woolen yarn is soft, light, stretchy, and full of air. It is thus a good insulator, and makes a good knitting yarn. Woolen yarn is in contrast to worsted yarn, in which the fibers are combed to lie parallel rather than carded, producing a hard, strong yarn.Burnham (1980), p. 191 Commercial manufacture The woolen and worsted process both require that the wool (and other similar animal fibres, cashmere, camel, etc.) be cleaned before mechanical processing. Woolen and worsted nomenclatures apply only to the textile processing of animal fibres, but it has become common to include fibre blends under these terms. The resultant fabrics will be classified as being either woolen or worsted, but this designation is assigned during fiber processing and yarn formation, not in the cloth or finished garment. A woven woolen fabric is one which is subjected to fabric finishing techniques de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dipsacus
''Dipsacus'' is a genus of flowering plant in the family Caprifoliaceae. The members of this genus are known as teasel, teazel or teazle. The genus includes about 15 species of tall herbaceous biennial plants (rarely short-lived perennial plants) growing to tall. ''Dipsacus'' species are native to Europe, Asia and northern Africa. Etymology The genus name (''Dipsacus'') is derived from the Greek word for thirst (''dipsa'') and refers to the cup-like formation made where sessile leaves merge at the stem. The name ''teasel'' derives from words such as Old English ''tǣsl'', ''tǣsel''; relating to the verb "to tease" – the dried heads of the plant were once used in the textile industry to raise the nap on woolen cloth. Description Teasels are easily identified with their prickly stem and leaves, and the inflorescence of purple, dark pink, lavender or white flowers that form a head on the end of the stem(s). The inflorescence is ovoid, long and broad, with a basal whorl of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcloth
Broadcloth is a dense, plain woven cloth, historically made of wool. The defining characteristic of broadcloth is not its finished width but the fact that it was woven much wider (typically 50 to 75% wider than its finished width) and then heavily milled (traditionally the cloth was worked by heavy wooden trip hammers in hot soapy water) in order to shrink it to the required width. The effect of the milling process is to draw the yarns much closer together than could be achieved in the loom and allow the individual fibres of the wool to bind together in a felting process, which results in a dense, blind face cloth with a stiff drape which is highly weather-resistant, hard wearing and capable of taking a cut edge without the need for being hemmed. The manufacturing process originates from Flanders, the type of cloth was also made in Leiden and several parts of England at the end of the medieval period. The raw material was short staple wool, carded and spun into yarn and then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shearing Blades Gri 33125000004685 0150
Sheep shearing is the process by which the Wool, woollen fleece of a sheep is cut off. The person who removes the sheep's wool is called a ''Sheep shearer, shearer''. Typically each adult sheep is shorn once each year (a sheep may be said to have been "shorn" or "sheared", depending upon dialect). The annual shearing most often occurs in a shearing shed, a facility especially designed to process often hundreds and sometimes more than 3,000 sheep per day. Sheep are shorn in all seasons, depending on the climate, management requirements and the availability of a Wool classing, woolclasser and wikt:Special:Search/shearer, shearers. Ewes are normally shorn prior to lambing in the warmer months, but consideration is typically made as to the welfare of the lambs by not shearing during cold climate winters. However, in high country regions, pre lamb shearing encourages ewes to seek shelter among the hillsides so that newborn lambs aren't completely exposed to the elements. Shorn shee ...

Machine
A machine is a physical system using Power (physics), power to apply Force, forces and control Motion, movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by Animal power, animals and Human power, people, by natural forces such as Wind power, wind and Water power, water, and by Chemical energy, chemical, Thermal energy, thermal, or electricity, electrical power, and include a system of mechanism (engineering), mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input fo ...

Moleskin
Moleskin is a heavy cotton fabric, woven and then shorn to create a short, soft pile on one side. The feel and appearance of its nap is suede-like, less plush than velour and more like felt or chamois. The word is also used for clothing made from this fabric. Clothing made from moleskin is noted for its softness and durability. Some variants of the cloth are so densely woven as to be windproof. Its name is due to the soft brushed hand of the fabric, similar to mole fur. Though mole pelts have been used to make fur clothing, they are not referred to as "moleskin", which is also a term for soft, dense adhesive pads stuck to the skin to prevent blisters. Structure Moleskin is woven of carded cotton yarn in a dense weft-faced satin weave. The surface is napped or shorn to "produce a suede-like finish". Uses Moleskin fabric is commonly used to make trousers, also referred to as "moleskins", that are similar to jeans in terms of cut and construction. They similarly started as w ...
