Textile Testing
Textile testing is the process of measuring the properties and performance of textile materials—textile testing includes physical and chemical testing of raw materials to finished products. Textile testing assists textile production in selecting various types of fibers and their transformation into yarn, fabric, and finished goods such as clothing. The materials are evaluated at multiple stages of production to qualify, compare, and standardize to meet the norms of different production stages and consumer requirements. The testing of textiles is carried out in laboratories and in the field using simple to sophisticated testing methods and equipment. In textile testing, many analytical instruments and online monitoring systems are utilized. Textile testing adds value to different agencies involved in the textile supply chain, from production, distribution and consumption. Multiple units are utilized to measure textile fibers, threads, yarns, and fabrics. History Textile tes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists Are Working In The Lab
A scientist is a person who conducts Scientific method, scientific research to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have Terminal degree, advanced degrees in an area of science and pursue careers in various Sector (economic), sectors of the economy such ...

Colorimetry
Colorimetry is "the science and technology used to quantify and describe physically the human color perception". It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities. History The Duboscq colorimeter was invented by Jules Duboscq in 1870. Instruments Colorimetric equipment is similar to that used in spectrophotometry. Some related equipment is also mentioned for completeness. * A tristimulus colorimeter measures the tristimulus values of a color. * A spectroradiometer measures the absolute spectral radiance (intensity) or irradiance of a light source. * A spectrophotometer measures the spectral reflectance, transmittance, or relative irradiance of a color sample. * A ''spectrocolorimeter'' is a spectrophotometer that can ''calculate'' tristimulus values. * A densitometer measures the degree of light ...

Spinning (textiles)
Spinning is a twisting technique to form yarn from fibers. The fiber intended is drawn out, twisted, and wound onto a bobbin. A few popular fibers that are spun into yarn other than cotton, which is the most popular, are viscose (the most common form of rayon), and synthetic polyester. Originally done by hand using a spindle whorl, starting in the 500s AD the spinning wheel became the predominant spinning tool across Asia and Europe. The spinning jenny and spinning mule, invented in the late 1700s, made mechanical spinning far more efficient than spinning by hand, and especially made cotton manufacturing one of the most important industries of the Industrial Revolution. Process The yarn issuing from the drafting rollers passes through a thread-guide, round a Ring spinning#How it works, traveller that is free to rotate around a ring, and then onto a tube or bobbin, which is carried on to a Spindle (textiles), spindle, the axis of which passes through a center of the ring. The spin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Standard
European Standards (abbreviated EN, from the German name ("European Norm")) are technical standards which have been ratified by one of the three European standards organizations: European Committee for Standardization (CEN), European Committee for Electrotechnical Standardization (CENELEC), or European Telecommunications Standards Institute (ETSI). All ENs are designed and created by all interested parties through a transparent, open, and consensual process. European Standards are a key component of the Single European Market. They are crucial in facilitating trade and have high visibility among manufacturers inside and outside the European territory. A standard represents a model specification, a technical solution against which a market can trade. European Standards must be transposed into a national standard in all EU member states. This guarantees that a manufacturer has easier access to the market of all these European countries when applying European Standards. Member count ...

International Organization For Standardization
The International Organization for Standardization (ISO ) is an international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and (as of November 2022) it has published over 24,500 international standards covering almost all aspects of technology and manufacturing. It has 809 Technical committees and sub committees to take care of standards development. The organization develops and publishes standardization in all technical and nontechnical fields other than electrical and electronic engineering, which is handled by the IEC.Editors of Encyclopedia Britannica. 3 June 2021.International Organization for Standardization" ''Encyclopedia Britannica''. Retrieved 2022-04-26. It is headquartered in Geneva, Switzerland, and works in 167 countries . The three official languages of the ISO are English, Fren ...

British Standards
British Standards (BS) are the standards produced by the BSI Group which is incorporated under a royal charter and which is formally designated as the Standards organization#National standards bodies, national standards body (NSB) for the UK. The BSI Group produces British Standards under the authority of the charter, which lays down as one of the BSI's objectives to: Formally, as stated in a 2002 memorandum of understanding between the BSI and the United Kingdom Government, British Standards are defined as: Products and services which BSI certifies as having met the requirements of specific standards within designated schemes are awarded the Kitemark.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
