Textile Arts Of Africa
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, and different types of fabric. 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: consumer textiles for domestic purposes and technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, while in technical textiles, functional properties are the priority. The durability of textiles is an important property, with common cotton or blend garments (such as t-shirts) able t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weaving Jamdani At BSCIC Jamdani Palli, Narayanganj 113
Weaving is a method of textile production in which two distinct sets of yarn, yarns or threads are interlaced at right angles to form a textile, fabric or cloth. Other methods are knitting, crocheting, felting, and braid, braiding or plaiting. The longitudinal threads are called the Warp (weaving), 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 ...

Spacesuit
A space suit (or spacesuit) is an environmental suit used for protection from the harsh Space environment, environment of outer space, mainly from its Vacuum (outer space), vacuum as a highly specialized pressure suit, but also its temperature extremes, as well as Effects of ionizing radiation in spaceflight, radiation and micrometeoroids. Basic space suits are worn as a safety precaution inside spacecrafts in case of loss of cabin pressure. For extravehicular activity (EVA) more complex space suits are worn, featuring a portable life support system. Pressure suits are in general needed at low pressure environments above the Armstrong limit, at around above Earth. Space suits augment pressure suits with complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum. A self-contained oxygen supply and environ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crochet
Crochet (; ) is a process of creating textiles by using a crochet hook to interlock loops of yarn, thread (yarn), thread, or strands of other materials. The name is derived from the French term ''crochet'', which means 'hook'. Hooks can be made from different materials (aluminum, steel, metal, wood, bamboo, bone, etc.), sizes, and types (in-line, tapered, ergonomic, etc.). The key difference between crochet and knitting, beyond the implements used for their production, is that each stitch in crochet is completed before the next one, while knitting keeps many stitches open at a time. Some variant forms of crochet, such as Tunisian crochet and Broomstick lace, do keep multiple crochet stitches open at a time. Etymology The word crochet is derived from the French language, French word , a diminutive of ''croche'', in turn from the Germanic languages, Germanic ''croc'', both meaning "hook". It was used in 17th-century French lace-making, where the term ''Crochetage'' designated a sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonwoven Fabric
Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam. Applications Because nonwoven fabrics do not require the intermediate step of converting fibres to yarn, they have more flexibility in materials usage. Nonwoven fabrics may be single-use, have a limited life, or be very durable. Nonwoven fabrics are sometimes designed to provide specific functions such as absorbency, liquid repellence, resilience, stretch, softness, strength, flame retardancy, washability, cushioning, thermal insulation, acoustic insulation, filtration, use as a bacterial ba ...

Felt
Felt is a textile that is produced by matting, condensing, and pressing fibers together. Felt can be made of natural fibers such as wool or animal fur, or from synthetic fibers such as petroleum-based acrylic fiber, acrylic or acrylonitrile or wood pulp–based rayon. Blended fibers are also common. Natural fiber felt has special properties that allow it to be used for a wide variety of purposes. It is "fire-retardant and self-extinguishing; it dampens vibration and absorbs sound; and it can hold large amounts of fluid without feeling wet..." History Felt from wool is one of the oldest known textiles. Many cultures have legends about the origins of felt-making. Sumerian legend claims that the secret of feltmaking was discovered by Urnamman of Lagash. The story of Clement of Metz, Saint Clement and Saint Christopher relates that the men packed their sandals with wool to prevent blisters while fleeing from persecution. At the end of their journey the movement and sweat had turned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Fiber
Synthetic fibers or synthetic fibres (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms, such as plants like cotton or fur from animals. They are the result of extensive research by scientists to replicate naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). The first synthetic fibres Nylon was the first commercially successful synthetic thermoplastic polymer. DuPont began its research project in 1927. The first nylon, nylon 66, was synthesized on February 28, 1935, by Wallace Hume Carothers at DuPont's research facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Fiber
Natural fibers or natural fibres (see Spelling differences#-re, -er, spelling differences) are fibers that are produced by geology, geological processes, or from the bodies of plants or animals. They can be used as a component of Composite material, composite materials, where the orientation of fibers impacts the properties. Natural fibers can also be Felted, matted into sheets to make paper or felt. The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Georgia (country), Republic of Georgia that date back to 36,000 Before Present, BP. Natural fibers can be used for high-tech applications, such as Composite material, composite parts for automobiles and medical supplies. Compared to composites reinforced with glass fibers, composites with natural fibers have advantages such as lower density, better thermal insulation, and reduced skin irritation. Further, unlike glass fibers, natural fibers can be broken down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finishing (textiles)
In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing. The precise meaning depends on context. Fabric after leaving the loom or knitting machine is not readily useable. Called greige cloth at this stage, it contains natural and added impurities. Sometimes it is also processed at fiber or yarn stages of textile manufacturing. Grey fiber or yarn or fabric goes through a series of processes such as wet processing and finishing. Finishing is a broad range of physical and chemical treatments that complete one stage of textile manufacturing and may prepare for the next step, making the product more receptive to the next stage of manufacturing. Finishing adds value to the product and makes it more attractive, useful, and functional for the end-u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Textiles
Medical textiles are numerous Fiber, fiber-based materials intended for medical purposes. Medical textile is a sector of technical textiles that emphasizes fiber-based products used in health care applications such as Preventive healthcare, prevention, care, and hygiene. The spectrum of applications of medical textiles ranges from simple cotton bandages to advanced tissue engineering. Common examples of products made from medical textiles include Dressing (medical), dressings, Implant (medicine), implants, surgical sutures, certain medical devices, healthcare textiles, diapers, menstrual pads, Wet wipe, wipes, and barrier fabrics. Medical textiles include many fiber types, yarns, fabrics, non-woven materials, woven, braided, as well as knitted fabrics.

Indutech
Indutech (Industrial textiles) is the branch of technical textile that deals with textiles used in the diverse industrial applications such as in filtration, conveying, cleaning and other industrial uses. Industrial textiles These are the specially designed (unconventional) textiles useful in the industrial processes, products and services. Technical textiles are classified with their area of applications, and it is divided into twelve separate categories. Though certain sectors overlap each other. Industrial textiles can act as a component to strengthen other product, or act as a tool similar to filteration, or it can be a product (independently) sufficing several functions. Indutech has vast application areas like filtration, cleaning, chemical industry, electrical applications and in mechanical engineering. Indutech includes conveyor belts, drive belts, ropes and cordages, filtration products, glass battery separators, decatising and bolting cloth, AGM (absorption glass m ...

Geotextile
Geotextiles are versatile permeable fabrics that, when used in conjunction with soil, can effectively perform multiple functions, including separation, filtration, reinforcement, protection, and drainage. Typically crafted from polypropylene or polyester, geotextile fabrics are available in two primary forms: woven, which resembles traditional mail bag sacking, and nonwoven, which resembles felt. Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Geotextiles are durable and are able to soften a fall. Overall, these materials are referred to as geosynthetics and each configuration—geonets, geosynthetic clay liners, geogrids, geotextile tubes, and others—can yield benefits in geotechnical engineering, geotechnical and environmental engineering design. History Geotextiles were originally intended to be a substitute for granular soil filters. Geotextiles can also be referred to as ''filter fabrics''. In the 1950s, R.J. Barr ...
