Yak Fiber
Yak fiber is the term commonly used to refer yak fiber wool produced from the coat hair of yaks (''Bos grunniens''), a long-haired bovinae, bovine mainly found in the Himalayan region, Tibetan plateau, and some areas of Mongolia and Central Asia. Yak fiber wool has been used by nomads in the Trans-Himalayan region for over a thousand years to make clothing, tents, ropes and blankets. Types The coat hair of the yak is composed of three different types of fiber that vary greatly in appearance and characteristics. The quantity of fiber produced by one yak is dependent on factors such as sex, age and breed of the yak, and the proportions of the different layers vary throughout the different seasons. *The coarse: Mostly used by nomads in tent making, this fiber has a size range of 79–90 microns forming the outer coat of long hair that characterizes the appearance of the yak. *The mid-type: With a diameter size between 20–50 microns, this fiber is naturally strong but not strong ...

Bovinae
Bovines (subfamily Bovinae) comprise a diverse group of 10 genera of medium to large-sized ungulates, including cattle, bison, African buffalo, water buffalos, and the four-horned and spiral-horned antelopes. The evolutionary relationship between the members of the group is still debated, and their classification into loose tribes rather than formal subgroups reflects this uncertainty. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur. In many countries, bovid milk and meat Meat is animal flesh that is eaten as food. Humans have hunted, farmed, and scavenged animals for meat since prehistoric times.

Fiber
Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: *Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and die ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breathability
Breathability is the ability of a fabric to allow moisture vapor to be transmitted through the material. Mechanism Air permeability is the ability of a fabric to allow air to pass through it. While air permeable fabrics tend to have relatively high moisture vapor transmission, it is not necessary to be air permeable to be breathable. Moisture Vapor Transfer (MVT) in waterproof fabrics occurs by two processes: * Physical: Hydrophobic (water fearing) are water proof, yet steam permeable -microporous coatings or laminations have pores that are so small that liquid water cannot go through. However, vapor water molecules are many times smaller than the liquid state and can pass through these “micro pores”. * Chemical: Hydrophilic (water loving) / non-porous lamination or coating move moisture by chemical diffusion. The water molecule is positively charged and the hydrophilic PU is negatively charged, attracting the water through the intermolecular gaps of the PU. Because the ionic b ...

Lanolin
Lanolin (from Latin 'wool', and 'oil'), also called wool yolk, wool wax, or wool grease, is a wax secreted by the sebaceous glands of wool-bearing animals. Lanolin used by humans comes from domestic sheep breeds that are raised specifically for their wool. Historically, many pharmacopoeias have referred to lanolin as wool fat (''adeps lanae''); however, as lanolin lacks glycerides (glycerol esters), it is not a true fat. Lanolin primarily consists of sterol esters instead. Lanolin's waterproofing property aids sheep in shedding water from their coats. Certain breeds of sheep produce large amounts of lanolin. Lanolin's role in nature is to protect wool and skin from climate and the environment; it also plays a role in skin ( integumental) hygiene. Lanolin and its derivatives are used in the protection, treatment, and beautification of human skin. Composition A typical high-purity grade of lanolin is composed predominantly of long chain waxy esters (approximately 97% by weight) ...

Myristic Acid
Myristic acid (IUPAC name: tetradecanoic acid) is a common saturated fatty acid with the molecular formula CH3(CH2)12COOH. Its salts and esters are commonly referred to as myristates or tetradecanoates. It is named after the binomial name for nutmeg (''Myristica fragrans''), from which it was first isolated in 1841 by Lyon Playfair, 1st Baron Playfair, Lyon Playfair. Occurrence Nutmeg#Nutmeg butter, Nutmeg butter has 75% trimyristin, the triglyceride of myristic acid. Besides nutmeg, myristic acid is found in palm kernel oil, coconut oil, butterfat, 8–14% of bovine milk, and 8.6% of breast milk as well as being a minor component of many other animal fats. It is found in spermaceti, the crystallized fraction of oil from the sperm whale. It is also found in the rhizomes of the Iris (plant), Iris, including Orris root. Chemical behaviour Myristic acid acts as a Lipid-anchored protein, lipid anchor in biomembranes. Reduction (chemistry), Reduction of myristic acid yields myristy ...

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] |
Cashmere Wool
Cashmere wool, usually simply known as cashmere, is a fiber obtained from cashmere goats, pashmina goats, and some other breeds of goat. It has been used to make yarn, textiles and clothing for hundreds of years. Cashmere is closely associated with the Kashmir shawl, the word "cashmere" deriving from an anglicisation of ''Kashmir'', when the Kashmir shawl reached Europe in the 19th century. Both the soft undercoat and the guard hairs may be used; the softer hair is reserved for textiles, while the coarse guard hair is used for brushes and other non-apparel purposes. A number of countries produce cashmere and have improved processing techniques over the years but China and Mongolia are two of the leading producers as of 2019. Afghanistan is ranked third. Some yarns and clothing marketed as containing cashmere have been found to contain little to no cashmere fiber, so more stringent testing has been requested to make sure items are fairly represented. Poor land management and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wool
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 c ...

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...

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 ...

Clothing Industry
Clothing industry or garment industry summarizes the types of trade and industry along the production and value chain of clothing and garments, starting with the textile industry (producers of cotton, wool, fur, and synthetic fibre), embellishment using embroidery, via the fashion industry to apparel retailers up to trade with second-hand clothes and textile recycling. The producing sectors build upon a wealth of clothing technology some of which, like the loom, the cotton gin, and the sewing machine heralded industrialization not only of the previous textile manufacturing practices. Clothing industries are also known as allied industries, fashion industries, garment industries, or soft good industries. Terminology By the early 20th century, the industry in the developed world often involved immigrants in "sweat shops", which were usually legal but were sometimes illegally operated. They employed people in crowded conditions, working manual sewing machines, and being paid le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
