Wool
posted Sunday, 12 March 2006
Wool is the fibre derived from the hair of animals of the Caprinae family, principally sheep and goats, but the hair of other mammals such as alpacas may also be called wool. This article deals with the wool produced from domestic sheep.
Wool is the fibre produced as the outer coat of sheep. Most of the fibre from domestic sheep has two qualities that distinguish it from hair or fur: it has scales which overlap like shingles on a roof and it is crimped; in some fleeces the wool fibres have more than 20 bends per inch.
Both the scaling and the crimp make it possible to spin and felt the fleece. They help the individual fibres attach to each other so that they stay together. Because of the crimp, wool fabrics have a greater bulk than other textiles and retain air, which causes the product to retain heat. Insulation also works both ways; bedouins and tuaregs use wool clothes to keep the heat out.
The amount of crimp corresponds to the fineness of the wool fibres. A fine wool like merino may have up to a hundred crimps per inch, while the coarser wools like karakul may have as few as one to two crimps per inch.
Hair, by contrast, has little if any scale and no crimp and little ability to bind into yarn. On sheep, the hair part of the fleece is called kemp. The relative amounts of kemp to wool vary from breed to breed, and make some fleeces more desirable for spinning, felting or carding into batts for quilts or other insulating products.
Wool is generally a creamy white colour, although some breeds of sheep produce natural colors such as black, brown (also called moorit) and grey.
Wool straight off a sheep contains a high level of grease (thus "greasy wool") which contains valuable lanolin. In this state it can be worked into yarn or knitted into water-resistant mittens, such as those of the Aran Island fishermen. The grease is generally removed for processing by scouring with detergent and alkali.
After shearing, the wool is separated into five main categories: fleece (which makes up the vast bulk), pieces, bellies, crutchings and locks. The latter four are packaged and sold separately. The quality of fleece is determined by a technique known as wool classing, whereby a qualified woolclasser tries to group wools of similar gradings together to maximise the return for the farmer or sheep owner.
The fibre diameter of wool varies from 15 micrometres (superfine merino) to 30 or more micrometres for the coarser wools. The finer diameters are generally more valuable.
History
As the raw material has been readily available since the widespread domestication of sheep—and of goats, the other provider of wool— the use of felted or woven wool for clothing and other fabrics characterizes some of the earliest civilizations. Prior to invention of shears - probably in the Iron Age - the wool was plucked out by hand or by bronze combs. The oldest European woollen textile, of ca. 1500 BCE , was preserved in a Danish bog [1].
In Roman times, wool, linen and leather clothed the European population: the cotton of India was a curiosity that only naturalists had heard of, and silk, imported along the Silk Road from China, was an extravagant luxury. Pliny's Natural History records a Roman reputation for producing the finest wool was enjoyed by Tarentum, where selective breeding had produced sheep with a superior fleece, but which required special care.
In medieval times, as trade connections expanded, the Champagne fairs revolved around the production of woollen cloth in small centers such as Provins; the network that the sequence of annual fairs developed meant that the woollens of Provins might find their way to Naples, Sicily, Cyprus, Majorca, Spain and even Constantinople (Braudel, 316). The wool trade developed into serious business, the generator of capital. In the thirteenth century, the wool trade was the economic engine of the Low Countries and of Central Italy; by the end of the following century Italy predominated, though in the 16th century Italian production turned to silk (Braudel p 312). Both pre-industries were based on English raw wool exports— rivalled only by the sheepwalks of Castile, developed from the fifteenth century— which were a significant source of income to the English crown, which from 1275 imposed an export tax on wool called the "Great Custom". Economies of scale were instituted in the Cistercian houses, which had accumulated great tracts of land during the twelfth and early thirteenth centuries, when land prices were low and labour still scarce. Raw wool was baled and shipped from North Sea ports to the textile cities of Flanders, notably Ypres and Ghent, where it was dyed and worked up as cloth. At the time of the Black Death, English textile industries accounted for about 10% of English wool production (Cantor 2001, 64); the English textile trade grew during the fifteenth century, to the point where export of wool was discouraged. Over the centuries, various British laws controlled the wool trade or required the use of wool even in burials. The smuggling of wool out of the country, known as owling, was at one time punishable by the cutting off of a hand. After the Restoration, fine English woollens began to compete with silks in the international market, partly aided by the Navigation Acts; in 1699 English crown forbade its American colonies to trade wool with anyone else but England itself.
A great deal of the value of woollen textiles was in the dyeing and finishing of the woven product. In each of the centers of the textile trade, the manufacturing process came to be subdivided into a collection of trades, overseen by an entrepreneur in the system English call the "putting-out" system, or "cottage industry" and the Germans term Verlagssystem. In this system of producing woolen cloth, until recently perpetuated in the production of Harris tweeds, the entrepreneur provides the raw materials and an advance, the remainder being paid upon delivery of the product. Written contracts bound the artisans to specified terms. Frernand Braudel traces the appearance of the system in the thirteenth-century economic boom, quoting a document of 1275 (Braudel, 317) The system effectively by-passed the guilds' restrictions.
Before the flowering of the Renaissance, the Medici and other great banking houses of Florence had built their wealth and banking system on their textile industry based on wool, overseen by the Arte della Lana, the wool guild: wool textile interests guided Florentine policies. Francesco Datini, the "merchant of Prato", established in 1383 an Arte della Lana for that small Tuscan city. The sheepwalks of Castile shaped the landscape and the fortunes of the meseta that lies in the heart of the Iberian peninsula; in the sixteenth century, a unified Spain allowed export of Merino lambs only with royal permission. The German wool market—based on sheep of Spanish origin—did not overtake British wool until comparatively late. Australia's colonial economy was based on sheep raising and the Australian wool trade eventually overtook that of the Germans by 1845, furnishing wool for Bradford, which developed as the heart of industrialized woollens production.

Production
Global wool production is approximately 1.3 million tonnes per annum of which 60% goes into apparel. Australia, China and New Zealand are leading commercial producers of wool. Most Australian wool comes from the merino breed. Breeds such as Lincoln and Romney produce coarser fibres and wool of these sheep is usually used for making carpets.
In the United States, Texas, New Mexico and Colorado also have large commercial sheep flocks and their mainstay is the Rambouillet (or French Merino). There is also a thriving 'home flock' contingent of small scale farmers who raise small hobby flocks of specialty sheep for the handspinning market. These small scale farmers may raise any type of sheep they wish, so the selection of fleeces is quite wide.

Uses
In addition to clothing, wool has been used for carpeting, felt, insulation (see links) and upholstery. Wool felt covers piano hammers and it is used to absorb odors and noise in heavy machinery and stereo speakers. Ancient Greeks lined their helmets with felt and Roman legionnaires used breastplates made of wool felt.
Shoddy is recycled or remanufactured wool. To make shoddy, existing wool fabric is cut or torn apart and respun. As this process makes the wool fibres shorter, the remanufactured fabric is inferior to the original. The recycled wool may be mixed with raw wool, wool noil, or another fibre such as cotton to increase the average fibre length. Such yarns are typically used as weft yarns with a cotton warp.
This process was invented in the Heavy Woollen District of West Yorkshire and created a micro-economy in this area for many years.
Ragg is a sturdy wool fibre made into yarn and used in many rugged applications like gloves.
