Shahtoosh
Shahtoosh (from Persian شاهتوش 'king of wools'), also known as Shatoush, is a wool obtained from the fur of the chiru (''Pantholops hodgsonii'', also called Tibetan antelope). Also, shawls made from the wool of the chiru are called shahtoosh. Shahtoosh is the finest animal wool, followed by vicuña wool. As undomesticated wild animals, the chirus cannot be shorn, so they are killed for this purpose. Due to the severe decline of the chiru population by 90% in the second half of the 20th century, they were internationally classified as a critically endangered species until 2016. Since 2016, they have been classified as a near threatened species due to species conservation programs and partial recovery of population size. The wool is mostly used to make luxurious scarves and shawls, although the production, sale, and acquisition of shahtoosh has been illegal under CITES since 1979. On the black market, shahtoosh shawls fetch prices ranging from $5,000 to $20,000. Properti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pantholops Hodgsonii (chiru) Fibre Natural Vs
The Tibetan antelope or chiru (''Pantholops hodgsonii'') (, pronounced ; ) is a medium-sized bovid native to the northeastern Tibetan plateau. Most of the population live within the Chinese border, while some scatter across India and Bhutan in the high altitude plains, hill plateau and montane valley. Fewer than 150,000 mature individuals are left in the wild, but the population is currently thought to be increasing. In the 1980s and the 1990s, they had become endangered due to massive illegal poaching. They are hunted for their extremely soft, light and warm underfur which is usually obtained after death. This underfur, known as ''shahtoosh'' (a Persian word meaning "king of fine wools"), is used to weave luxury shawls. Shahtoosh shawls were traditionally given as wedding gifts in India and it takes the underfur of three to five adult antelopes to make one shawl. Despite strict controls on trade of shahtoosh products and CITES listing, there is still demand for these luxu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Vicuña Wool
Vicuña wool refers to the hair of the South American vicuña, a camelid related to llamas and alpacas. The wool has, after shahtoosh, the second smallest fiber diameter of all animal hair and is the most expensive legal wool. Properties The down hair of the vicuña used for the production of vicuña wool is, with an average hair diameter of 11–13.5 microns, one of the finest Fur, animal hairs. Only shahtoosh, the hair of the Tibetan antelope, is finer, with an average diameter of 8–13 microns.Carol Ekarius: ''The Fleece & Fiber Sourcebook.'' Storey Publishing, 2011, , pp. 381–382. Among animal textile fibers, besides shahtoosh, only the various silks and byssus have a smaller fiber diameter. The surface structure of the fiber has scales as in sheep wool.Miguel Angel Gardetti: ''Handbook of Sustainable Luxury Textiles and Fashion.'' Springer, 2015, , p. 107. The scale spacing is between 7 and 14 scale rings per 100 microns.Subramanian Senthilkannan Muthu, Miguel A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Shawl
A shawl (from ''shāl'') is a simple item of clothing, loosely worn over the shoulders, upper body and arms, and sometimes also over the head. It is usually a rectangular piece of Textile, cloth, but can also be Square (geometry), square or triangular in shape. Other shapes include oblong shawls. History Kashmir was a pivotal point in the history of the shawl, serving as the birthplace of one of the most coveted garments in the world. Perhaps the most widely known woven textiles are the famed Kashmir shawls. The ''Kanikar'', for instance, has intricately woven designs that are formalized imitations of nature. The ''Chinar'' leaf (plane tree leaf), ''apple and cherry blossoms'', the ''rose and tulip'', the ''almond and pear'', the ''nightingale''—these are done in deep mellow tones of maroon, dark red, gold yellow and browns. Yet another type of Kashmir shawl is the ''Jamia Vr'', which is a brocaded woollen fabric sometimes in pure wool and sometimes with a little cotton adde ...

Dyeing
Dyeing is the application of dyes or pigments on textile materials such as fibers, yarns, and fabrics with the goal of achieving color with desired color fastness. Dyeing is normally done in a special solution containing dyes and particular chemical material. Dye molecules are fixed to the fiber by absorption, diffusion, or bonding with temperature and time being key controlling factors. The bond between the dye molecule and fiber may be strong or weak, depending on the dye used. Dyeing and printing are different applications; in printing, color is applied to a localized area with desired patterns. In dyeing, it is applied to the entire textile. The primary source of dye, historically, has been nature, with the dyes being extracted from plants or animals. Since the mid-19th century, however, humans have produced artificial dyes to achieve a broader range of colors and to render the dyes more stable for washing and general use. Different classes of dyes are used for different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Guard Hair
Guard hair or overhair is the outer layer of hair of most mammals, which overlay the fur. Guard hairs are long and coarse and protect the rest of the pelage (fur) from abrasion and frequently from moisture. They are visible on the surface of the fur and usually lend a characteristic contour and color pattern. Underneath the contour hair is the short, dense, fine down. There are three types of guard hair: awns, bristles, and spines.G. A. Feldhamer, J. F. Merritt, C. Krajewski, J. L. Rachlow, K. M. Stewart. ''Mammalogy: Adaptation, Diversity, Ecology.

Light Microscope
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible spectrum, visible light and a system of lens (optics), lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although many complex designs aim to improve optical resolution, resolution and sample contrast (vision), contrast. The object is placed on a stage and may be directly viewed through one or two eyepieces on the microscope. In high-power microscopes, both eyepieces typically show the same image, but with a stereo microscope, slightly different images are used to create a 3-D effect. A camera is typically used to capture the image (micrograph). The sample can be lit in a variety of ways. Transparent objects can be lit from below and solid objects can be lit with light coming through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Changtang
The Changtang (alternatively spelled Changthang or Qangtang) is a part of the high altitude Tibetan Plateau in western and northern Tibet extending into the southern edges of Xinjiang as well as southeastern Ladakh, India, with vast highlands and giant lakes. From eastern Ladakh, the Changtang stretches approximately east into Tibet as far as modern Qinghai. The Changtang is home to the Changpa, a nomadic Tibetan people. The two largest settlements within the Tibetan Changtang are Rutog Town, which is the seat of Rutog County, and Domar Township, the seat of Shuanghu County. Climate The summers are warm but short and thunderstorms can occur at any time of year, often accompanied with hail. Meanwhile, the winters are cold and Arctic-like despite the latitude, primarily due to the high elevation. History Changtang was once ruled by a culture known as the Zhangzhung, which later merged with Tibetan culture. People The people of the Changtang are nomadic pastoralists. They a ...

Cashmere Wool
Cashmere wool, usually simply known as cashmere, is a fiber obtained from cashmere goats, Changthangi, 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 anglicization 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. Cashmere is a hygroscopic fiber, absorbing and releasing water from the air based on the surrounding environment. This helps regulate the body in both warm and cool temperatures. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Standard Deviation
In statistics, the standard deviation is a measure of the amount of variation of the values of a variable about its Expected value, mean. A low standard Deviation (statistics), deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. The standard deviation is commonly used in the determination of what constitutes an outlier and what does not. Standard deviation may be abbreviated SD or std dev, and is most commonly represented in mathematical texts and equations by the lowercase Greek alphabet, Greek letter Sigma, σ (sigma), for the population standard deviation, or the Latin script, Latin letter ''s'', for the sample standard deviation. The standard deviation of a random variable, Sample (statistics), sample, statistical population, data set, or probability distribution is the square root of its variance.
