Natural wool is the fiber obtained from sheep and other animals. For example cashmere and the mohair of goats, Qiviut of muskoxen, angora of rabbits, and Camelid wool. Sheep wool is the most preferred because it has important physical properties distinguish it from camel hair, goat hair, and others.
The wool is consists of protein with a low proportion of fat. So it is quite different from cotton which is mainly cellulose. Global raw wool production is approximately 3. There is currently a global interest in reviving the use of organic wool, an initiative that is funded by wool producers from Australia, Britain and New Zealand in an effort to encourage more producers to use wool in the carpet and clothing industry instead of other synthetic fibers.
Wool fibers have been important to the primitive human tribes since more than 10, BC. Wool was woven and coordinated by the Babylonians as well as in northern European tribes. Textile tools were relatively basic. After Norman's invasion of Greece in the 12th century, Greek weavers were sent to Italy as slaves who stimulated the Italian textile industry into extraordinary works. In the 14th century, the Flemish Weavers escaped from the Spanish invasion into England, leading to the flourishing of the wool industry.
Moroccan Arabs used to breed sheep and produce fine wool. They invented many wool weaving processes and transported them to Andalusia Spain. During the fifteenth and eighteenth centuries, sheep and wool were an important economic force. For example, countries such as England and Spain prohibited the export of sheep and raw wool.
In , two-thirds of England's foreign trade was based on exports of woolen textiles. The Spanish sheep Merino flourished in South Africa. Later some descendants of the Spanish Merino sheep were sent to Australia. The first Merino sheep arrived in Australia in The sheep were descendants of the Royal Merino herd of Spain.
After selective breeding Australian farmers produced soft Australian Merino wool and then shipped to England for industrialization. The Arabs of the Levant also cared about raising sheep and wool yarn. This act was to protect producers and consumers from the unknown existence of substitutes and mixtures in wool products. This law required that all products containing wool except for upholstery and floor coverings bear a mark indicating the content and proportions of materials in the fabric.
The fall in the price of wool began in late due to the decline in demand for natural wool with increased use of synthetic fibers resulting in a sharp decline in production.
Hillcreston Pinehill Partnership produced this bale, which measured The wool fibers have three-dimensional crimps, 25 waves per 10 cm in fine fiber, and 4 waves per 10 cm for coarse fibers. The fiber length ranges from 3. The fiber length of cm is used in the garment industry because this length allows the yarn to be manufactured with greater precision.
The diameter of the fiber varies from 14 micrometers to more than 45 micrometers. The higher price is paid for fibers with the fine diameter, especially if they are identical in diameter. The color of sheep's wool varies from white to brown and black. White is more desirable than other colors. The dark fibers cannot be successfully dyed for the difficulty of removing or hiding the natural color.
Wool fibers absorb water from the surrounding atmosphere better than other fabric fibers because they have pores and interstitial spaces in their composition. Wool is a good insulation for heat, preventing heat from leaking out, and cold air from leakage inside. Therefore, woolen textiles are used as a protective cover for heat in hot places as well as cold in the cold winter. Through microscopic examination of wool fibers, we find that they are made from protein molecules.
Keratin protein is a crystalline copolymer; the repeated units are amino acids. Wool fibers are also cross-linked through the disulfide bonds present in amino acids Cysteine. It was found that wool has two structures. One is Alpha-keratin and the second is Beta-keratin that was through X-ray diffraction. The microstructure of wool fibers consists of three basic parts: the cuticle, cortex, and medulla.
The cuticle epidermis is a layer of overlapping cells surrounding wool fibers. There are three cuticles epicuticle, exocuticle, and endocuticle. There are two basic types of cortical cells; ortho cortical, and paracortical, each with a different chemical composition. In superior fibers, these two types of cells are of distinct halves.
The cells expand differently when the moisture absorbed, making the fiber curve, this creates a crease in the wool. In rough fibers, ortho and para cortical-chemical cells are more random so there is less curl. Also, fiber crease makes wool an insulator for air.
The medulla is a mass of degenerated cells in the central part of the fiber. This layer may disappear or be difficult to see in the fine wool. Fine Soft wool : In this type, the fiber diameter does not exceed 25 microns and the average length of wool is cm.
Wool fibers here are very wavy, the fiber density is large, the fat ratio is high, and the wool is white. This type of wool can be obtained from the Merino sheep breeds. Medium Semi-soft wool : Wool is white in color and average fat. The thickness of wool fiber ranges from microns and wool length ranges from cm.
This type of wool can be obtained from the Tsigai , Suffolk, Hampshire, and Tunis sheep breeds. Long wool: This type of wool is white, has a coarse and dry feel. This wool can be obtained from the Awassi and Lincoln sheep breeds. Carpet wool: This type of wool contains more fats than coarse wool as well as more softness. This wool can be obtained from Tajikistan Marco Polo sheep and Karakul sheep. This kind of wool is more suitable for the carpet industry.
Hand shearing: In this method, different types of scissors are used, requiring a long time and a large number of workers, and may cause injury to the animals, as well as irregular shearing wool. Automatic shearing: It is made by electric machines, and spread in many countries because of the saving of time and effort, in addition, to get good quality shearing, and do not cause any injuries to sheep when carried out by trained shearers.
Preliminary studies of woolen underwear have found that they prevent heat and rashes because they absorb moisture more than other fibers. A blend of wool and Kevlar a synthetic fiber used in body armor were discovered by researchers at the Royal Melbourne School of Technology of Fashion and Textiles. Mixing wool with Kevlar reduced the cost of using Kevlar alone.
Hand washing is the best way for natural woolen fabrics. Wash the wool with a large amount of warm water, just by pressing it. Do not use hot water as it changes the properties of wool. When wool is rubbed with soap, it causes shrinkage of the wool and increases wrinkles. It is also not necessary to increase the amount of soap used because when the soap dissolves in the water gives an alkaline effect and if the quantity increased, it will increase its bad effect in the wool fabric.
Also, it is best to change the washing water two or three times, and water temperature is equal at all times. Wool fibers have been blended will both natural or synthetic fibers to produce a material that possesses qualities of each fiber.
For example, Wool is blended with cotton in various ratios. In this kind of fabric cotswool , wool fiber provides warmth property due to its scaly surface, as air entrapped in the scales acts as an insulator. Also, wool contributes to resiliency and abrasion resistance.
On the other hand, Cotton adds strength and reduces the cost of the yarn and fabric. The process of spinning cotton and wool fibers is quite different because they require different types of machinery and processing methods. Silk and wool blended fabrics show excellent value as improved strength, firmness, and smoothness characteristics.
Silk and wool blended fabric provides better comfort than pure wool or pure silk. Wool also is mixed with synthetic threads at different rates to improve the properties of synthetic fibers or to obtain new features fabric. This mixing is done under appropriate pressure and temperature, as well as using special machines due to the different properties of the wool fibers from the characteristics of synthetic threads.

Comments are not for promoting your articles or other sites. Thank you very much, Linda. Natural wool is important and very useful to us away from diseases and allergies and also has a long history in the industry. Wool is such a amazing fiber that creates wonderful textiles. It;s been around for centuries and they've been using a similar manufacturing process that is still used today. A great in-depth article with lots of interesting details.
Thanks, RTalloni for reading the article and comment. The production of natural wool in the whole world is few because it needs a high cost so the price of the product will be expensive. It has been replaced with synthetic fibers and this is certainly unhealthy.
There is a global call to revive natural fibers, including wool. Such an interesting read. Learning about the Hillcreston Pinehill Partnership still has me smiling. To own the finest wool must be amazing!

Natural Wool: Its Characteristics, Manufacturing Process, and Good Washing of Woolen Fabrics
Girls are taught from an early age by their mothers how to create beautiful clothing from alpaca and sheep fur. In many rural Andean villages, before shearing begins, an offering is made to the gods and the Pachamama Mother Earth. We visited an Andean weaving center in Chinchero where a group of women, all dressed in typical clothing and speaking amongst themselves in native Quechua language, welcomed us to watch while they washed, spun, thread, weaved and dyed their alpaca and sheep fibers. Here we see an Andean girl who is washing sheep fibers using an ancient mixture of water and root mixture. Peru has more than one kind of naturally-occurring plant detergents, which are traditionally used to wash shorn wool and fiber. In the Sacred Valley, Sacha Paraqay is a root which is grated into the wash water and mixed to create a foamy lather. The wool came out bright white, and ready to dye.SEE VIDEO BY TOPIC: How to Wash Raw Wool Fleece

Soaps are cleaning agents that are usually made by reacting alkali e. A soap is a salt of a compound known as a fatty acid. A soap molecule consists of a long hydrocarbon chain composed of carbons and hydrogens with a carboxylic acid group on one end which is ionic bonded to a metalion, usually a sodium or potassium. The hydrocarbon end is nonpolar and is soluble in nonpolar substances such as fats and oils , and the ionic end the salt of a carboxylic acid is soluble in water. Soap is made by combining tallow or other hard animal fat or vegetable or fish oil with an alkaline solution. The two most important alkalis in use are caustic soda and caustic potash. A detergent is an effective cleaning product because it contains one or more surfactants. Because of their chemical makeup, the surfactants used in detergents can be engineered to perform well under a variety of conditions.

Washing wool fibers. Chinchero, Peru.
Textile manufacturing is a major industry. It is based on the conversion of fibre into yarn , yarn into fabric. These are then dyed or printed, fabricated into clothes. Different types of fibres are used to produce yarn. Cotton remains the most important natural fibre, so is treated in depth. There are many variable processes available at the spinning and fabric-forming stages coupled with the complexities of the finishing and colouration processes to the production of a wide range of products. Cotton is the world's most important natural fibre. In the year , the global yield was 25 million tons from 35 million hectares cultivated in more than 50 countries.
Back to Scouring of wool. Wool is processed to yarn mainly via two systems: woollen and worsted. Scourers tend to specialise in wools for one system or the other.
As with many discoveries of early man, anthropologists believe the use of wool came out of the challenge to survive. In seeking means of protection and warmth, humans in the Neolithic Age wore animal pelts as clothing. Finding the pelts not only warm and comfortable but also durable, they soon began to develop the basic processes and primitive tools for making wool. By B.
