⭐ Core Definition: Silk

Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin. It is most commonly produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori, which are reared in captivity (sericulture). The shimmery appearance of silk is due to the triangular prism-like structure of the silk fiber, which causes silk cloth to refract incoming light at different angles, thus producing different colors.

Harvested silk is produced by numerous insects; generally, only the silk of various moth caterpillars has been used for textile manufacturing. Research into other types of silk, which differ at the molecular level, has been conducted. Silk is produced primarily by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera (bees, wasps, and ants), silverfish, caddisflies, mayflies, thrips, leafhoppers, beetles, lacewings, fleas, flies, and midges. Other types of arthropods also produce silk, most notably various arachnids, such as spiders.

Silk in the context of Weaving

Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. The longitudinal threads are called the warp and the lateral threads are the weft, woof, or filling. The method in which these threads are interwoven affects the characteristics of the cloth.Cloth is usually woven on a loom, a device that holds warp threads in place while filling threads are woven through them. A fabric band that meets this definition of cloth (warp threads with a weft thread winding between) can also be made using other methods, including tablet weaving, back strap loom, or other techniques that can be done without looms.

The way the warp and filling threads interlace with each other is called the weave. The majority of woven products are created with one of three basic weaves: plain weave, satin weave, or twill weave. Woven cloth can be plain or classic (in one colour or a simple pattern), or can be woven in decorative or artistic design.

Silk in the context of Textile arts

Textile arts are arts and crafts that use plant, animal, or synthetic fibers to construct practical or decorative objects.

Textiles have been a fundamental part of human life since the beginning of civilization. The methods and materials used to make them have expanded enormously, while the functions of textiles have remained the same, there are many functions for textiles. Whether it be clothing or something decorative for the house/shelter. The history of textile arts is also the history of international trade. Tyrian purple dye was an important trade good in the ancient Mediterranean. The Silk Road brought Chinese silk to India, Africa, and Europe, and, conversely, Sogdian silk to China. Tastes for imported luxury fabrics led to sumptuary laws during the Middle Ages and Renaissance. The Industrial Revolution was shaped largely by innovation in textiles technology: the cotton gin, the spinning jenny, and the power loom mechanized production and led to the Luddite rebellion.

Silk in the context of History of Asia

The history of Asia can be seen as the collective history of East Asia, South Asia, Southeast Asia and West Asia. The continent is home to two of the world's oldest, continuous civilizations, Chinese civilization and Indian civilization.

Asia was also home to the Mesopotamian, Indus Valley and Yellow river civilizations. These civilizations were among the first in the world, and developed around fertile river valleys as they were conducive to agriculture. They shared many similarities and likely exchanged technologies and ideas such as mathematics and the wheel. Other inventions such as writing likely developed independently as did Cities, states, and empires.

Silk in the context of Silk Road

The Silk Road was a network of Asian trade routes active from the second century BCE until the mid-15th century. Spanning over 6,400 km (4,000 mi) on land, it played a central role in facilitating economic, cultural, political, and religious interactions between the Eastern and Western worlds. The name "Silk Road" was coined in the late 19th century, but some 20th- and 21st-century historians instead prefer the term Silk Routes, on the grounds that it more accurately describes the intricate web of land and sea routes connecting Central, East, South, Southeast, and West Asia as well as East Africa and Southern Europe. In fact, some scholars criticise or even dismiss the idea of silk roads and call for a new definition or alternate term. According to them, the literature using this term has "privileged the sedentary and literate empires at either end of Eurasia" thereby ignoring the contributions of steppe nomads. In addition, the classic definition sidelines civilisations like India and Iran.

The Silk Road derives its name from the highly lucrative trade of silk textiles that were primarily produced in China. The network began with the expansion of the Han dynasty (202 BCE – 220 CE) into Central Asia around 114 BCE, through the missions and explorations of the Chinese imperial envoy Zhang Qian, which brought the region under unified control. The Chinese took great interest in the security of their trade products, and extended the Great Wall of China to ensure the protection of the trade route. The Parthian Empire provided a vital bridge connecting the network to the Mediterranean. Meanwhile, the rise of the Roman Empire in the west further established the western terminus of the interconnected trade system. By the first century CE, Chinese silk was widely sought after in Rome, Egypt, and Greece. Other lucrative commodities from the East included tea, dyes, perfumes, and porcelain; among Western exports were horses, camels, honey, wine, and gold. Aside from generating substantial wealth for emerging mercantile classes, the proliferation of goods such as paper and gunpowder greatly affected the trajectory of political history in several theatres in Eurasia and beyond.

Silk in the context of Domestication

Domestication is a multi-generational mutualistic relationship in which an animal species, such as humans or leafcutter ants, takes over control and care of another species, such as sheep or fungi, to obtain from them a steady supply of resources, such as meat, milk, or labor. The process is gradual and geographically diffuse, based on trial and error. Domestication affected genes for behavior in animals, making them less aggressive. In plants, domestication affected genes for morphology, such as increasing seed size and stopping the shattering of cereal seedheads. Such changes both make domesticated organisms easier to handle and reduce their ability to survive in the wild.

The first animal to be domesticated by humans was the dog, as a commensal, at least 15,000 years ago. Other animals, including goats, sheep, and cows, were domesticated around 11,000 years ago. Among birds, the chicken was first domesticated in East Asia, seemingly for cockfighting, some 7,000 years ago. The horse came under domestication around 5,500 years ago in central Asia as a working animal. Among invertebrates, the silkworm and the western honey bee were domesticated over 5,000 years ago for silk and honey, respectively.

Silk in the context of Thread (yarn)

A thread is a long strand of material, often composed of several filaments or fibres, used for joining, creating or decorating textiles. Ancient Egyptians were known for creating thread using plant fibers, wool and hair. Today, thread can also be made of many different materials including but not limited to cotton, wool, flax, nylon, silk, polyester etc. There are also metal threads (sometimes used in decorative textiles), which can be made of fine wire.

Thread is similar to yarn, cord, twine, or string, and there is some overlap between the way these terms are used. However, thread is most often used to mean materials fine and smooth enough for sewing, embroidery, weaving, or making lace or net. Yarn is often used to mean a thicker and softer material, suitable for knitting and crochet. Cords, twines or strings are usually stronger materials, suitable for tying and fastening.

Silk in the context of Bulletproof vest

A bulletproof vest, also known as a ballistic vest or bullet-resistant vest, is a type of body armor designed to absorb impact and prevent the penetration of firearm projectiles and explosion fragments to the torso. The vest can be either soft—as worn by police officers, security personnel, prison guards, and occasionally private citizens to protect against stabbing attacks or light projectiles—or hard, incorporating metallic or para-aramid components. Soldiers and police tactical units typically wear hard armour, either alone or combined with soft armour, to protect against rifle ammunition or fragmentation. Additional protection includes trauma plates for blunt force and ceramic inserts for high-caliber rounds. Bulletproof vests have evolved over centuries, from early designs like those made for knights and military leaders to modern-day versions. Early ballistic protection used materials like cotton and silk, while contemporary vests employ advanced fibers and ceramic plates.

Silk in the context of Satin weave

A satin weave is a type of fabric weave that produces a characteristically glossy, smooth or lustrous material, typically with a glossy top surface and a dull back; it is not durable, as it tends to snag. It is one of three fundamental types of textile weaves alongside plain weave and twill weave.

The satin weave is characterised by four or more fill or weft yarns floating over a warp yarn, and four warp yarns floating over a single weft yarn. Floats are missed interfacings, for example where the warp yarn lies on top of the weft in a warp-faced satin. These floats explain the high lustre and even sheen, as unlike in other weaves, light is not scattered as much when hitting the fibres, resulting in a stronger reflection. Satin is usually a warp-faced weaving technique in which warp yarns are "floated" over weft yarns, although there are also weft-faced satins. If a fabric is formed with a satin weave using filament fibres such as silk, polyester or nylon, the corresponding fabric is termed a 'satin', although some definitions insist that a satin fabric is only made from silk. If the yarns used are short-staple yarns such as cotton, the fabric formed is considered a sateen.
