Sericin
Sericin is a protein created by ''Bombyx mori'' (silkworms) in the production of silk. Silk is a fibre produced by the silkworm in production of its cocoon. It consists mainly of two proteins, fibroin and sericin. Silk consists of 70–80% fibroin and 20–30% sericin; fibroin being the structural center of the silk, and sericin being the gum coating the fibres and allowing them to stick to each other. Structure Sericin is composed of 18 different amino acids, of which 32% is serine. The secondary structure is usually a random coil, but it can also be easily converted into a β-sheet conformation, via repeated moisture absorption and mechanical stretching. The serine hydrogen bonds give its glue-like quality. The genes encoding sericin proteins have been sequenced. Its C-terminal part contains many serine-rich repeats. Using gamma ray examination, it was determined that sericin fibers are composed typically of three layers, all with fibers running in different patterns of ...

Bangladeshi Clothing
Bangladeshis ( bn, বাংলাদেশী ) are the citizens of Bangladesh, a South Asian country centered on the transnational historical region of Bengal along the eponymous bay. Bangladeshi citizenship was formed in 1971, when the permanent residents of the former East Pakistan were transformed into citizens of a new republic. Bangladesh is the world's eighth most populous nation. The vast majority of Bangladeshis are ethnolingustically Bengalis, an Indo-Aryan people. The population of Bangladesh is concentrated in the fertile Bengal delta, which has been the center of urban and agrarian civilizations for millennia. The country's highlands, including the Chittagong Hill Tracts and parts of the Sylhet Division, are home to various tribal minorities. Bengali Muslims are the predominant ethnoreligious group of Bangladesh with a population of 150.36 million, which makes up 91.04% of the country's population as of 2022. The minority Bengali Hindu population made up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sericulture
Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, '' Bombyx mori'' (the caterpillar of the domestic silkmoth) is the most widely used and intensively studied silkworm. Silk was believed to have first been produced in China as early as the Neolithic Period. Sericulture has become an important cottage industry in countries such as Brazil, China, France, India, Italy, Japan, Korea, and Russia. Today, China and India are the two main producers, with more than 60% of the world's annual production. History According to Confucian text, the discovery of silk production dates to about 2700 BC, although archaeological records point to silk cultivation as early as the Yangshao period (5000–3000 BC). In 1977, a piece of ceramic created 5400–5500 years ago and designed to look like a silkworm was discovered in Nancun, Hebei, providing the earliest known evidence of sericulture. Also, by caref ...

Bangladesh Sericulture Research And Training Institute
The Bangladesh Sericulture Research and Training Institute is an autonomous national research institute that carries out research on sericulture (silk farming) and supports the sericulture industry in Bangladesh. The organization is located in the city of Rajshahi. History The institute traces its origins to the Silk Institute that was established in Rajshahi in 1898, during the colonial British Raj period. During the post-colonial East Pakistan period (1955–1971) there were two institutes, the Silk Research Institute and Silk Technology Institute. Following national independence, the institutes were merged to form Silk Research and Training Institute in 1974. Now renamed the Sericulture Research and Training Institute, it is under the Bangladesh Sericulture Board. The institute is the only one in Bangladesh specializing in silk research. It has developed a number of high yielding Mulberry (plant), Mulberry plant cultivars and silkworms. See also * * References ...

Designers
A designer is a person who plans the form or structure of something before it is made, by preparing drawings or plans. In practice, anyone who creates tangible or intangible objects, products, processes, laws, games, graphics, services, or experiences can be referred to as a designer. Overview Historically, the main area of design was regarded as only architecture, which was understood as the major art. The design of clothing, furniture, and other common artifacts were left mostly to tradition or artisans specializing in hand making them. With the increasing complexity in industrial design of today's society, and due to the needs of mass production where more time is usually associated with more cost, the production methods became more complex and with them, the way designs and their production are created. The classical areas are now subdivided into smaller and more specialized domains of design (landscape design, urban design, interior design, industrial design, furniture d ...

Textile
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: Domestic purposes onsumer textilesand technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, but in technical textiles, functional properties are the priority. Geotextiles, industrial textiles, medical textiles, and many other areas are examples of technical textiles, whereas clothing and ...

Tassar Silk
Tussar silk (alternatively spelled as tussah, tushar, tassar, tussore, tasar, tussur, or tusser, and also known as (Sanskrit) ''kosa'' silk) is produced from larvae of several species of silkworms belonging to the moth genus '' Antheraea'', including '' A. assamensis'', '' A. paphia'', '' A. pernyi'', '' A. roylei'', and '' A. yamamai''. These silkworms live in the wild forests in trees belonging to '' Terminalia'' species and ''Shorea robusta'', as well as other food plants such as jamun and oak found in South Asia, eating the leaves of the trees on which they live. Tussar silk is valued for its rich texture and natural, deep-gold colour, and varieties are produced in many countries, including China,Su Jing, Lun Luo, ''Landlord and Labor in Late Imperial China: Case Studies from Shandong'', Harvard University Asia Center, 1978 India, Japan, and Sri Lanka. Process To kill the silkworms, the cocoons are dried in the sun. A variation of the process exists in which the silkworms ...

Eri Silk
Eri silk (Khasi'': Ryndia)'' is the product of the domesticated silkworm '' Samia ricini'', found mainly in North East India and some part of China and Japan. It was imported to Thailand in 1974. The name "eri" is derived from the Assamese word "era", which means "castor", as the silkworm feeds on castor plants. Another type of eri silk is "Ailanthus silk moth", refers to the host plant, Borkesseu, Ailanthus excelsa, practiced in China. Eri silk is also known as endi or errandi in India. The woolly white silk is often referred to as the fabric of peace when it is processed without killing the silkworm. This process results in a silk called Ahimsa silk. Moths leave the cocoon and then the cocoons are harvested to be spun. The eri silkworm is the only completely domesticated silkworm other than ''Bombyx mori''. Process Eri caterpillars eat a number of plants, including Kesseru. In India, it is grown in the states of Meghalaya, Assam, Nagaland, Manipur, Arunachal Pradesh, Bih ...

Mulberry
''Morus'', a genus of flowering plants in the family Moraceae, consists of diverse species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the genus has 64 identified species, three of which are well-known and are ostensibly named for the fruit color of the best-known cultivar: white, red, and black mulberry ('' Morus alba'', '' M. rubra'', and '' M. nigra'', respectively), with numerous cultivars. ''M. alba'' is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. ''M. alba'' is also the species most preferred by the silkworm, and is regarded as an invasive species in Brazil and the United States. The closely related genus '' Broussonetia'' is also commonly known as mulberry, notably the paper mulberry (''Broussonetia papyrifera''). Description Mulberries are fast-growing when young, and can grow to tall. The l ... [...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 ...

Silkworm
The domestic silk moth (''Bombyx mori''), is an insect from the moth family Bombycidae. It is the closest relative of '' Bombyx mandarina'', the wild silk moth. The silkworm is the larva or caterpillar of a silk moth. It is an economically important insect, being a primary producer of silk. A silkworm's preferred food are white mulberry leaves, though they may eat other mulberry species and even the osage orange. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths (other species of ''Bombyx'') are not as commercially viable in the production of silk. Sericulture, the practice of breeding silkworms for the production of raw silk, has been under way for at least 5,000 years in China, whence it spread to India, Korea, Nepal, Japan, and the West. The domestic silk moth was domesticated from the wild silk moth '' Bombyx mandarina'', which has a range from northern India to northern China, Korea, ...
