Wool Scour
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack cri ...

Yarn
Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework. Yarn can be made of a number of natural or synthetic materials, and comes in a variety of colors and thicknesses (referred to as "weights"). Although yarn may be dyed different colours, most yarns are solid coloured with a uniform hue. Etymology The word yarn comes from Middle English, from the Old English ''gearn'', akin to Old High German ''garn'', "yarn," Dutch "garen," Italian ''chordē'', "string," and Sanskrit ''hira'', "band." History The human production of yarn is known to have existed since the Stone Age and earlier prehistory, with ancient fiber mat ...

Cuticle (hair)
The hair cuticle is the outermost part of the hair shaft.James, William; Berger, Timothy; Elston, Dirk (2005) ''Andrews' Diseases of the Skin: Clinical Dermatology'' (10th ed.). Saunders. Page 8. . It is formed from dead cells, overlapping in layers, which form scales that strengthen and protect the hair shaft. While the cuticle is the outermost layer, it is not responsible for the color of the hair. Melanin is the pigment that gives hair its color and is found in the cortex Cortex or cortical may refer to: Biology * Cortex (anatomy), the outermost layer of an organ ** Cerebral cortex, the outer layer of the vertebrate cerebrum, part of which is the ''forebrain'' *** Motor cortex, the regions of the cerebral cortex i ....

Karakul (sheep)
Karakul or Qaraqul (named after Qorakoʻl, a city in Bukhara Region in Uzbekistan) is a breed of domestic sheep which originated in Central Asia. Some archaeological evidence points to Karakul sheep being raised there continuously since 1400 BC. Hailing from the desert regions of Central Asia, Karakul sheep are renowned for their ability to forage and thrive under extremely harsh living conditions. They can survive severe drought conditions because of a special quality they have, storing fat in their tails. Karakul are also raised in large numbers in Namibia, having first been brought there by German colonists in the early 20th century. They are currently listed as endangered. Use by humans Karakul sheep are a multi-purpose breed, kept for milking, meat, pelts, and wool. As a fat-tailed breed, they have a distinctive meat. Many adult Karakul are double-coated; in this case, spinners separate the coarse guard hair from the undercoat. Karakul is a relatively coarse fiber used ...

Merino
The Merino is a breed or group of breeds of domestic sheep, characterised by very fine soft wool. It was established in Spain near the end of the Middle Ages, and was for several centuries kept as a strict Spanish monopoly; exports of the breed were not allowed, and those who tried risked the death penalty. During the eighteenth century, flocks were sent to the courts of a number of European countries, including France (where they developed into the Rambouillet), Hungary, the Netherlands, Prussia, Saxony, Estonia, Livonia and Sweden. The Merino subsequently spread to many parts of the world, including South Africa, Australia, and New Zealand. Numerous recognised breeds, strains and variants have developed from the original type; these include, among others, the American Merino and Delaine Merino in the Americas, the Australian Merino, Booroola Merino and Peppin Merino in Oceania, the Gentile di Puglia, Merinolandschaf and Rambouillet in Europe. The Australian Poll Merino is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Elasticity (physics)
In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. This is in contrast to ''plasticity'', in which the object fails to do so and instead remains in its deformed state. The physical reasons for elastic behavior can be quite different for different materials. In metals, the atomic lattice changes size and shape when forces are applied (energy is added to the system). When forces are removed, the lattice goes back to the original lower energy state. For rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied. Hooke's law states that the force required to deform elastic objects should be directly proportional to the distance of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crimp (wool)
Wool classing is the production of uniform, predictable, low-risk lines of wool, carried out by examining the characteristics of the wool in its raw state and classing (grading) it accordingly. Wool classing is done by a wool classer. Basis for classification Some of the qualities a wool classer examines when classing wool are:Wool Classification Manual by the National Wool Growers Association, of Southafrica * '' Breed of the sheep'': Shedding breeds will increase the risk of medullated or pigmented fibers. Any sheep likely to have dark fibers should be shorn last to avoid contamination. The age of the sheep will have a bearing on the diameter and value of the fibers of wool, too. * ''Usage of chemicals'': Ensure that all rule ...

Tuareg People
The Tuareg people (; also spelled Twareg or Touareg; endonym: ''Imuhaɣ/Imušaɣ/Imašeɣăn/Imajeɣăn'') are a large Berber ethnic group that principally inhabit the Sahara in a vast area stretching from far southwestern Libya to southern Algeria, Niger, Mali, and Burkina Faso. Traditionally nomadic pastoralists, small groups of Tuareg are also found in northern Nigeria. The Tuareg speak languages of the same name (also known as ''Tamasheq''), which belong to the Berber branch of the Afroasiatic family. The Tuaregs have been called the "blue people" for the indigo dye coloured clothes they traditionally wear and which stains their skin. They are a semi-nomadic people who practice Islam, and are descended from the indigenous Berber communities of Northern Africa, which have been described as a mosaic of local Northern African (Taforalt), Middle Eastern, European (Early European Farmers), and Sub-Saharan African-related ancestries, prior to the Arab expansion.

Bedouin
The Bedouin, Beduin, or Bedu (; , singular ) are nomadic Arab tribes who have historically inhabited the desert regions in the Arabian Peninsula, North Africa, the Levant, and Mesopotamia. The Bedouin originated in the Syrian Desert and Arabian Desert but spread across the rest of the Arab world in West Asia and North Africa after the spread of Islam. The English word ''bedouin'' comes from the Arabic ''badawī'', which means "desert dweller", and is traditionally contrasted with ''ḥāḍir'', the term for sedentary people. Bedouin territory stretches from the vast deserts of North Africa to the rocky sands of the Middle East. They are traditionally divided into tribes, or clans (known in Arabic as ''ʿašāʾir''; or ''qabāʾil'' ), and historically share a common culture of herding camels and goats. The vast majority of Bedouins adhere to Islam, although there are some fewer numbers of Christian Bedouins present in the Fertile Crescent. Bedouins have been referred ...
