Wool is the textile
fiber
obtained from sheep
and certain other animals, including cashmere
from goats
, mohair
from goats, qiviut
from muskoxen, vicuña
, alpaca
, camel
from animals in the camel family, and angora
from rabbits
.
Wool has several qualities that distinguish it from hair or fur: it is crimped, it is elastic
, and it grows in staples (clusters). The term wool is usually restricted to describing the fibrous protein
derived from the specialized skin
cells called follicles
in sheep.
the fleece by helping the individual fibers 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; Bedouin
s and Tuaregs use wool clothes to keep heat out.
The amount of crimp corresponds to the fineness of the wool fibers. A fine wool like Merino
may have up to 100 crimps per inch, while the coarser wools like karakul may have as few as 1 to 2. 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 batt
s for quilts or other insulating products including the famous Tweed (cloth)
cloth of Scotland.
Wool fibers are hydrophilic, meaning they readily absorb moisture. Wool fibers are hollow. Wool can absorb moisture almost one-third of its own weight.
Wool absorbs sound like many other fabrics. Wool is generally a creamy white color, although some breeds of sheep produce natural colors such as black, brown, silver, and random mixes.
Wool ignites at a higher temperature than cotton
and some synthetic fibers. It has lower rate of flame spread
, low heat release, low heat of combustion, and does not melt or drip; it forms a char which is insulating and self-extinguishing, and contributes less to toxic gases and smoke than other flooring products, when used in carpets. Wool carpets are specified for high safety environments, such as trains and aircraft. Wool is usually specified for garments for fire-fighters, soldiers, and others in occupations where they are exposed to the likelihood of fire.
Wool is resistant to static electricity
, as the moisture retained within the fabric conducts electricity. This is why wool garments are much less likely to spark or cling to the body. The use of wool car seat covers or carpets reduces the risk of a shock when a person touches a grounded object. Wool is considered by the medical profession to be hypoallergenic.
Sheep shearing
is the process by which the woollen fleece of a sheep is cut off.
After shearing, the wool is separated into four main categories: fleece (which makes up the vast bulk), broken, bellies, and locks. The quality of fleeces is determined by a technique known as wool classing
, whereby a qualified person called a wool classer groups wools of similar gradings together to maximize the return for the farmer or sheep owner. In Australia
and New Zealand
, before being auctioned all Merino fleece wool is objectively measured for micron
, yield (including the amount of vegetable matter), staple length, staple strength, and sometimes color and comfort factor.
, as well as dirt, dead skin, sweat residue, pesticide, and vegetable matter. Before the wool can be used for commercial purposes, it must be scoured, a process of cleaning the greasy wool. Scouring may be as simple as a bath in warm water, or as complicated as an industrial process using detergent
and alkali
, and specialized equipment.
In commercial wool, vegetable matter is often removed by chemical carbonization
. In less processed wools, vegetable matter may be removed by hand, and some of the lanolin left intact through use of gentler detergents. This semi-grease wool can be worked into yarn and knitted into particularly water-resistant mittens or sweaters, such as those of the Aran Island
fishermen. Lanolin removed from wool is widely used in cosmetic
products such as hand creams. Wool has to be cleaned for a long time because it is so thick.
Merino wool is typically 3-5 inches in length and is very fine (between 12-24 microns
). The finest and most valuable wool comes from Merino
hoggets. Wool taken from sheep produced for meat is typically more coarse, and has fibers that are 1.5 to 6 in (38.1 to 152.4 mm) in length. Damage or breaks in the wool can occur if the sheep is stressed while it is growing its fleece, resulting in a thin spot where the fleece is likely to break.
Wool is also separated into grades based on the measurement of the wool's diameter in microns and also its style. These grades may vary depending on the breed or purpose of the wool. For example:
Any wool finer than 25 microns can be used for garments, while coarser grades are used for outerwear or rugs. The finer the wool, the softer it is, while coarser grades are more durable and less prone to pilling
.
The finest Australia
n and New Zealand
Merino wools are known as 1PP which is the industry benchmark of excellence for Merino wool that is 16.9 micron and finer. This style represents the top level of fineness, character, color, and style as determined on the basis of a series of parameters in accordance with the original dictates of British Wool as applied today by the Australian Wool Exchange (AWEX) Council. Only a few dozen of the millions of bales auctioned every year can be classified and marked 1PP.
, ca. 1500 BC, was preserved in a Danish bog.
Prior to invention of shears - probably in the Iron Age
- the wool was plucked out by hand or by bronze combs. 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 the Elder
records in his Natural History that the 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 wool 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. 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. Both pre-industries were based on English raw wool exports - rivaled only by the sheepwalk
s 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". The importance of wool to the English economy can be shown by the fact that since the 14th Century, the presiding officer of the House of Lords
has sat on the "Woolsack
", a chair stuffed with wool.
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 labor 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; 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 but England herself.
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 a system called by the English the "putting-out" system, or "cottage industry", and the Verlagssystem by the Germans. In this system of producing wool cloth, until recently perpetuated in the production of Harris tweed
s, 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. Fernand Braudel
traces the appearance of the system in the thirteenth-century economic boom, quoting a document of 1275 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. The Industrial Revolution
introduced mass production technology into wool and wool cloth manufacturing. 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.
Due to decreasing demand with increased use of synthetic fibers, wool production is much less than what it was in the past. The collapse in the price of wool began in late 1966 with a 40% drop; with occasional interruptions, the price has tended down. The result has been sharply reduced production and movement of resources into production of other commodities, in the case of sheep growers, to production of meat.
Superwash wool (or washable wool) technology first appeared in the early 1970s to produce wool that has been specially treated so that it is machine washable and may be tumble-dried. This wool is produced using an acid bath that removes the "scales" from the fiber, or by coating the fiber with a polymer that prevents the scales from attaching to each other and causing shrinkage. This process results in a fiber that holds longevity and durability over synthetic materials, while retaining its shape.
In December 2004, a bale of the world's finest wool, averaging 11.8 micron, sold for $3,000 per kilogram at auction in Melbourne
, Victoria. This fleece wool tested with an average yield of 74.5%, 68 mm long, and had 40 newtons per kilotex strength. The result was $AUD279,000 for the bale.
The finest bale of wool ever auction
ed sold for a seasonal record of 269,000 cents per kilo during June 2008. This bale was produced by the Hillcreston Pinehill Partnership and measured 11.6 microns, 72.1% yield and had a 43 Newtons per kilotex strength measurement. The bale realized $247,480 and was exported to India
.
During 2007 a new wool suit was developed and sold in Japan that can be washed in the shower, and dries off ready to wear within hours with no ironing required. The suit was developed using Australian Merino wool and it enables woven products made from wool, such as suits, trousers and skirts, to be cleaned using a domestic shower at home.
In December 2006 the General Assembly of the United Nations proclaimed 2009 to be the International Year of Natural Fibres

sheep. New Zealand
is the second-largest producer of wool, and the largest producer of crossbred wool. China

, Romney
, Tukidale, Drysdale and Elliotdale produce coarser fibers, and wool from these sheep is usually used for making carpet

Organic wool is becoming more and more popular. This wool is very limited in supply and much of it comes from New Zealand and Australia. It is becoming easier to find in clothing and other products, but these products often carry a higher price. Wool is environmentally preferable (as compared to petroleum-based Nylon
or Polypropylene
) as a material for carpets as well, in particular when combined with a natural binding and the use of formaldehyde
-free glues.
Animal rights
groups have noted issues with the production of wool, such as Mulesing
.
. Sale by Sample is a method in which a mechanical claw takes a sample from each bale in a line or lot of wool. These grab samples are bulked, objectively measured, and a sample of not less than 4 kg is displayed in a box for the buyer to examine. The Australian Wool Exchange (AWEX) conducts sales primarily in Sydney
, Melbourne
, Newcastle
, and Fremantle
. There are about 80 brokers and agents throughout Australia.
About 7% of Australian wool is sold by private treaty on farms or to local wool-handling facilities. This option gives wool growers benefit from reduced transport, warehousing, and selling costs. This method is preferred for small lots or mixed butts in order to make savings on reclassing and testing.
About 5% of Australian wool is sold over the internet on an electronic offer board. This option gives wool growers the ability to set firm price targets, reoffer passed in wool and offer lots to the market quickly and efficiently. This method works well for tested lots as buyers use these results to make a purchase. 97% of wool is sold without sample inspection; however, as of Dec 2009, 59% of wool listed had been passed in from auction. Growers through certain brokers can allocate their wool to a sale and what price their wool will be reserved at.
Sale by tender can achieve considerable cost savings on wool clips large enough to make it worthwhile for potential buyers to submit tenders. Some marketing firms sell wool on a consignment basis, obtaining a fixed percentage as commission.
Forward selling: Some buyers offer a secure price for forward delivery of wool based on estimated measurements or the results of previous clips. Prices are quoted at current market rates and are locked in for the season. Premiums and discounts are added to cover variations in micron, yield, tensile strength, etc., which are confirmed by actual test results when available.
Another method of selling wool includes sales direct to wool mills.
Less than half of New Zealand
's wool is sold at auction, while around 45% for farmers sell wool directly to private buyers and end-users. Some businesses in New Zealand like Blue House Yarns have turned to selling organic wool
, a new trend on wool production.
United States
sheep producers market wool with private or cooperative wool warehouses, but wool pools are common in many states. In some cases, wool is pooled in a local market area but sold through a wool warehouse. Wool offered with objective measurement test results is preferred. Imported apparel wool and carpet wool goes directly to central markets, where it is handled by the large merchants and manufacturers.
, wool has been used for blankets, horse rugs, saddle cloths, carpet
ing, felt
, wool insulation
(also 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.
Wool has also been traditionally used to cover cloth diapers. Wool fiber exteriors are hydrophobic (repel water) and the interior of the wool fiber is hygroscopic (attracts water); this makes a wool garment able to cover a wet diaper while inhibiting wicking, so outer garments remain dry. Wool felted and treated with lanolin
is water resistant, air permeable, and slightly antibacterial, so it resists the buildup of odor. Some modern cloth diapers use felted wool fabric for covers, and there are several modern commercial knitting
patterns for wool diaper covers.
Initial studies of woollen underwear have found it prevented heat and sweat rashes because it more readily absorbs the moisture than other fibers.
Merino wool has been used in baby sleep products such as swaddle baby wrap blankets and infant sleeping bags.
Wool is an animal protein, and as such it can be used as a soil fertiliser, being a slow release source of nitrogen and ready made amino acids.
Researchers at the Royal Melbourne Institute of Technology school of fashion and textiles have discovered that a blend of wool and kevlar, the synthetic fiber widely used in body armor, was lighter and cheaper and worked better in damp conditions than kevlar alone. Kevlar, when used alone loses about 20 per cent of its effectiveness when wet and therefore required an expensive waterproofing process. Wool increased friction in a vest with 28-30 layers of fabric, to provide the same level of bullet resistance as 36 layers of Kevlar alone.
Shoddy or recycled wool is made by cutting or tearing apart existing wool fabric and respinning the resulting fibers. As this process makes the wool fibers shorter, the remanufactured fabric is inferior to the original. The recycled wool may be mixed with raw wool, wool noil
, or another fiber such as cotton
to increase the average fiber length. Such yarn
s 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 fiber made into yarn and used in many rugged applications like gloves.
Worsted
is a strong, long-staple, combed
wool yarn with a hard surface.
Woollen is a soft, short-staple, carded
wool yarn typically used for knitting. In traditional weaving, woollen weft yarn (for softness and warmth) is frequently combined with a worsted warp yarn for strength on the loom.
wool, Ermenegildo Zegna
, has offered awards for Australian wool producers. In 1963, the first Ermenegildo Zegna Perpetual Trophy was presented in Tasmania for growers of "Superfine skirted Merino fleece". In 1980, a national award, the Ermenegildo Zegna Trophy for Extrafine Wool Production, was launched. In 2004, this award became known as the Ermenegildo Zegna Unprotected Wool Trophy. In 1998, an Ermenegildo Zegna Protected Wool Trophy was launched for fleece from sheep coated for around nine months of the year.
In 2002, the Ermenegildo Zegna Vellus Aureum Trophy was launched for wool that is 13.9 micron and finer. Wool from Australia, New Zealand
, Argentina
, and South Africa
may enter, and a winner is named from each country. In April 2008, New Zealand won the Ermenegildo Zegna Vellus Aureum Trophy for the first time with a fleece that measured 10.8 microns. This contest awards the winning fleece weight with the same weight in gold as a prize, hence the name.
In 2010 an ultra-fine, 10 micron fleece, from Windradeen, near Pyramul, New South Wales
set a new world record in the fineness of wool fleeces when it won the Ermenegildo Zegna Vellus Aureum International Trophy.
Since 2000, Loro Piana
has awarded a cup for the world’s finest bale of wool that produces just enough fabric for 50 tailor-made suits. The prize is awarded to an Australian or New Zealand wool grower who produces the year's finest bale.
The New England
Merino Field days which display local studs, wool, and sheep are held during January, every two years (in even numbered years) around the Walcha, New South Wales
district. The Annual Wool Fashion Awards, which showcase the use of Merino wool by fashion designers, are hosted by the city of Armidale, New South Wales
in March each year. This event encourages young and established fashion designers to display their talents. During each May, Armidale hosts the annual New England Wool Expo to display wool fashions, handicrafts, demonstrations, shearing competitions, yard dog trials, and more.
In July, the annual Australian Sheep and Wool Show is held in Bendigo, Victoria
. This is the largest sheep and wool show in the world, with goats and alpacas as well as woolcraft competitions and displays, fleece competitions, sheepdog trials, shearing, and wool handling. The largest competition in the world for objectively-measured fleeces is the Australian Fleece Competition, which is held annually at Bendigo. In 2008, there were 475 entries from all states of Australia with first and second prizes going to the Northern Tablelands, New South Wales

Quality
The quality of wool is determined by the following factors, fiber diameter, crimp, yield, colour, and staple strength. Fiber diameter is the single most important wool characteristic determining quality and price.Merino wool is typically 3-5 inches in length and is very fine (between 12-24 microns
Micron (wool)

hoggets. Wool taken from sheep produced for meat is typically more coarse, and has fibers that are 1.5 to 6 in (38.1 to 152.4 mm) in length. Damage or breaks in the wool can occur if the sheep is stressed while it is growing its fleece, resulting in a thin spot where the fleece is likely to break.
Wool is also separated into grades based on the measurement of the wool's diameter in microns and also its style. These grades may vary depending on the breed or purpose of the wool. For example:
- <15.5 - Ultrafine Merino
- 15.6-18.5 - Superfine Merino
- 18.6-20 - Fine Merino
- 20.1-23 - Medium Merino
- 23< - Strong Merino

History
Wild sheep were more hairy than woolly. Although sheep were domesticated nine to eleven thousand years ago, archaeological evidence from statuary found at sites in Iran suggests that selection for woolly sheep may have begun around 6000 BC,, with the earliest woven wool garments having only been dated to two to three thousand years later. Woolly-sheep were introduced into Europe from the Near East in the early part of the 4th millennium BC. The oldest known European wool textileTextile

At the time of the Black Death, English textile industries accounted for about 10% of English wool production; 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.

Due to decreasing demand with increased use of synthetic fibers, wool production is much less than what it was in the past. The collapse in the price of wool began in late 1966 with a 40% drop; with occasional interruptions, the price has tended down. The result has been sharply reduced production and movement of resources into production of other commodities, in the case of sheep growers, to production of meat.
Superwash wool (or washable wool) technology first appeared in the early 1970s to produce wool that has been specially treated so that it is machine washable and may be tumble-dried. This wool is produced using an acid bath that removes the "scales" from the fiber, or by coating the fiber with a polymer that prevents the scales from attaching to each other and causing shrinkage. This process results in a fiber that holds longevity and durability over synthetic materials, while retaining its shape.

This method is preferred for small lots or mixed butts in order to make savings on reclassing and testing.
About 5% of Australian wool is sold over the internet on an electronic offer board. This option gives wool growers the ability to set firm price targets, reoffer passed in wool and offer lots to the market quickly and efficiently. This method works well for tested lots as buyers use these results to make a purchase. 97% of wool is sold without sample inspection; however, as of Dec 2009, 59% of wool listed had been passed in from auction. Growers through certain brokers can allocate their wool to a sale and what price their wool will be reserved at.
Sale by tender can achieve considerable cost savings on wool clips large enough to make it worthwhile for potential buyers to submit tenders. Some marketing firms sell wool on a consignment basis, obtaining a fixed percentage as commission.
Forward selling: Some buyers offer a secure price for forward delivery of wool based on estimated measurements or the results of previous clips. Prices are quoted at current market rates and are locked in for the season. Premiums and discounts are added to cover variations in micron, yield, tensile strength, etc., which are confirmed by actual test results when available.

Researchers at the Royal Melbourne Institute of Technology school of fashion and textiles have discovered that a blend of wool and kevlar, the synthetic fiber widely used in body armor, was lighter and cheaper and worked better in damp conditions than kevlar alone. Kevlar, when used alone loses about 20 per cent of its effectiveness when wet and therefore required an expensive waterproofing process. Wool increased friction in a vest with 28-30 layers of fabric, to provide the same level of bullet resistance as 36 layers of Kevlar alone.
