Galoshes , also known by many other names , are a type of overshoe or rubber boot that is put on over shoes to keep them from getting muddy or wet during inclement weather.
81-443: A zipper , zip , or fly , formerly known as a clasp locker , is a commonly used device for binding together two edges of fabric or other flexible material. Used in clothing (e.g. jackets and jeans ), luggage and other bags , camping gear (e.g. tents and sleeping bags ), and many other items, zippers come in a wide range of sizes, shapes, and colors. In 1892, Whitcomb L. Judson , an American inventor from Chicago, patented
162-493: A blend of cotton and polyester can be more durable and easier to maintain than material woven solely from cotton. Other than sharing functional properties, blending makes the products more economical. Union or Union fabrics is the 19th century term for blended fabrics. While it is no longer in use. Mixture or mixed cloth is another term used for blended cloths when different types of yarns are used in warp and weft sides. Blended textiles are not new. Fiber composition
243-605: A broader application than cloth. Fabric is synonymous with cloth, material, goods, or piece goods . The word 'fabric' also derives from Latin, with roots in the Proto-Indo-European language . Stemming most recently from the Middle French fabrique , or "building," and earlier from the Latin fabrica ('workshop; an art, trade; a skillful production, structure, fabric'), the noun fabrica stems from
324-544: A cave in the Republic of Georgia dated to 34,000 BCE suggests that textile-like materials were made as early as the Paleolithic era. The speed and scale of textile production have been altered almost beyond recognition by industrialization and the introduction of modern manufacturing techniques. The textile industry grew out of art and craft and was kept going by guilds . In the 18th and 19th centuries, during
405-423: A clipped version, and the slider has a gap above the zipper teeth for separating the ridge seal. This seal is structurally weak against internal pressure, and can be separated by pressure within the sealed container pushing outward on the ridges, which simply flex and spread apart, potentially allowing air or liquid entry. Ridge-sealed zippers are sometimes used on lower-cost surface dry suits . Some zippers include
486-547: A continuous zipper chain. Within the first year of operation, Sundbäck's machinery was producing a few hundred feet (around 100 meters) of fastener per day. In March of the same year, Mathieu Burri, a Swiss inventor, improved the design by adding a lock-in system attached to the last teeth, but his version never got into production due to conflicting patents. In 1923, during a trip to Europe, Sundbäck sold his European rights to Martin Othmar Winterhalter, who improved
567-466: A designed ability for the slider to hold in a steady open or closed position, resisting forces that would try to move the slider and open the zipper unexpectedly. There are two common ways this is accomplished: The zipper handle can have a short protruding pin stamped into it, which inserts between the zipper teeth through a hole on the slider, when the handle is folded down flat against the zipper teeth. This appears on some brands of trousers. The handle of
648-485: A form of currency. Textiles were among the objects offered to the gods [votive offering] in ancient Greece for religious purposes. The smallest component of a fabric is fiber; fibers are typically spun into yarn, and yarns are used to make fabrics. Fibers are very thin and hair-like structures. The sources of fibers may be natural , synthetic , or both. Global fiber production per person has increased from 8.4 kilograms in 1975 to 14.3 kilograms in 2021. After
729-597: A further step of the production. Cloth may also be used synonymously with fabric , but often specifically refers to a piece of fabric that has been processed or cut. Textiles are various materials made from fibers and yarns. The term "textile" was originally only used to refer to woven fabrics, but today it covers a broad range of subjects. Textiles are classified at various levels, such as according to fiber origin (natural or synthetic), structure (woven, knitted, nonwoven), finish, etc. However, there are primarily two types of textiles: Textiles have an assortment of uses,
810-452: A high-pitched zip when used . In many jackets and similar garments, the opening is closed completely when the slider is at the top end. Some jackets have double-separating zippers with two sliders on the tape. When the sliders are on opposite ends of the tape, the jacket is closed. If the lower slider is raised then the bottom part of the jacket may be opened to allow more comfortable sitting or bicycling. When both sliders are lowered then
891-518: A long, continuous strand of yarn. Yarns are then used to make different kinds of fabric by weaving, knitting, crocheting , knotting , tatting , or braiding . After manufacturing, textile materials are processed and finished to add value, such as aesthetics, physical characteristics, and increased usefulness. The manufacturing of textiles is the oldest industrial art . Dyeing , printing , and embroidery are all different decorative arts applied to textile materials. The word 'textile' comes from

#1732790551898972-559: A modest drop due to COVID-19 pandemic in 2020, global fiber output rebounded to 113 million tons in 2021. Global fiber output roughly doubled from 58 million tons in 2000 to 113 million tons in 2021 and is anticipated to reach 149 million tons in 2030. The demand for synthetic fibers is increasing rapidly. This has numerous causes. Reasons include its low price, the demand-supply imbalance of cotton, and its [Synthetic fibers'] versatility in design and application. Synthetic fibers accounts for 70% of global fiber use, mainly polyester. By 2030,
1053-497: A pneumatic street railway, patented a "Shoe-Fastening". The device served as a (more complicated) hook-and-eye shoe fastener. With the support of businessman Colonel Lewis Walker, Judson launched the Universal Fastener Company to manufacture the new device. Judson's "clasp locker" had its public debut at the 1893 Chicago World's Fair and met with little commercial success. Judson is sometimes given credit as
1134-598: A significant supplier to the apparel industry. In Europe, the Cremalleras Rubi company was established in 1926 in Spain. It sold over 30 million zippers in 2012. In 2005, The Guardian reported that China had 80 percent of the international market. Most of its product is made in Qiaotou, Yongjia County . From U.S. patent 1,219,881 , the following mechanism of the zipper improved by Gideon Sundback in 1917
1215-400: A single piece by the slider and increased the opening for the teeth guided by the slider. The patent for the "Separable Fastener" was issued in 1917. Gideon Sundbäck also created the manufacturing machine for the new device. The "S-L" or "strapless" machine took a special Y-shaped wire and cut scoops from it, then punched the scoop dimple and nib, and clamped each scoop on a cloth tape to produce
1296-430: A small block of wood by sawing a slot into one end so that it fits over the upper arm of the slider. Then a hammer can be used to exact a force onto the slider by carefully hitting the wood. When the protective coating of the diecast slider has been worn off by prolonged use, the material can corrode. The corrosion products are usually metal salts which can accumulate and block the slider from moving. When this happens,
1377-725: A textile product, including fiber, yarn, fabric, processing, and finishing , affects the final product. Components may vary among various textile products as they are selected based on their fitness for purpose . Fiber is the smallest component of a fabric; fibers are typically spun into yarn, and yarns are used to manufacture fabrics. Fiber has a hair-like appearance and a higher length-to-width ratio. The sources of fibers may be natural , synthetic , or both. The techniques of felting and bonding directly transform fibers into fabric. In other cases, yarns are manipulated with different fabric manufacturing systems to produce various fabric constructions. The fibers are twisted or laid out to make
1458-465: A variant of Late Latin calopes and calopedes , a partial calque of Greek καλοπόδιον ( kalopódion ) from κᾶλον ( kâlon ) ' wood ' and πούς ( poús ), ' foot ' . The calopedes of Late Antiquity were a kind of wooden clog and the name was occasionally reused in the Middle Ages for pattens , wooden bottoms strapped to softer shoes to allow outdoor use. By
1539-480: A zipper fails, it can either jam (i.e. get stuck) or partially break off. In 1851, Elias Howe received a patent for an "Improvement in Fastenings for Garments". He did not try seriously to market it, thus missing the recognition that he might otherwise have received. Howe's device was more like an elaborate drawstring than a true slide fastener. Forty-two years later, in 1893, Whitcomb L. Judson, who invented
1620-409: Is any material made of interlacing fibers, including carpeting and geotextiles , which may not necessarily be used in the production of further goods, such as clothing and upholstery . A fabric is a material made through weaving , knitting , spreading, felting, stitching, crocheting or bonding that may be used in the production of further products, such as clothing and upholstery, thus requiring
1701-434: Is decorative art of Odisha , a state in eastern India , used for umbrellas , wall hangings, lamp shades, and bags. To make a range of decorative products, colored cloth in the shapes of animals, birds, flowers, are sewn onto a base cloth. Architextiles , a combination of the words architecture and textile, are textile-based assemblages. Awnings are a basic type of architectural textile. Mughal Shahi Lal Dera Tent , which

Consequently, it will be seen that the members on one stringer alternate with those on
1863-475: Is made of fabric-reinforced polyethylene and is bonded to the rest of the suit) wrapped around the outside of each row of zipper teeth. When the zipper is closed, the two facing sides of the plastic sheeting are squeezed tightly against one another (between the C-shaped clips) both above and below the zipper teeth, forming a double seal. This double-mated surface is good at retaining both vacuum and pressure, but
1944-458: Is not correct. A Wellington boot is named after the Duke of Wellington and is a separate item from a pair of galoshes, which have continued in use as an overshoe cover. So, the first type of true galosh is a slightly smaller, oversize shoe or low boot made of thick rubber with a heavy sole and instep, also designed for heavy-duty use. The last is much thinner, of more flexible material, and more like
2025-560: 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
2106-412: Is often the least durable component in any garment or type of equipment. Most often, the zipper fails to close due to a worn or bent slider not being able to apply the necessary force to the sides of the teeth to cause them to interlock. This problem can sometimes be redressed by using small pliers to carefully squeeze the back part of the slider together a fraction of a millimeter. This can compensate for
2187-459: Is one of the important characteristics of the fibers. They have a greater length-to-width ratio [100 times the diameter]. Fibers need to be strong, cohesive, and flexible. The usefulness of fibers are characterized on the basis of certain parameters such as strength, flexibility, and length to diameter ratio, and spinnability. Natural fibers are relatively short [ staple ] in length. Synthetic fibers are produced in longer lengths called filaments. Silk
2268-410: Is pulled outward against spring tension, lifting the pins out from between the teeth as the slider moves. When the handle is released the pins automatically engage between the zipper teeth again. They are called "auto-lock sliders". A three-piece version of the above uses a tiny pivoting arm held under tension inside the hinge. Pulling on the handle from any direction lifts the pivoting arm's pins out of

The zipper is analogous in mechanism to a bobby pin , where the person's hand slides hair into and out of the pin's "contractible jaw". Zippers have entered into urban legends . American folklorist Jan Brunvand noted that "The zipper has been

Originally applied to woven fabrics , the term "textiles" is now used to encompass a diverse range of materials, including fibers, yarns , and fabrics , as well as other related items. A "fabric" is defined as any thin, flexible material made from yarn, directly from fibers, polymeric film, foam, or any combination of these techniques. Fabric has

Although cloth is a type of fabric, not all fabrics can be classified as cloth due to differences in their manufacturing processes, physical properties, and intended uses. Materials that are woven, knitted, tufted, or knotted from yarns are referred to as cloth, while wallpaper, plastic upholstery products, carpets, and nonwoven materials are examples of fabrics. Textiles themselves are too fragile to survive across millennia;

A galosh that only wraps around a shoe's upper is known as a spat or gaiter . Among bootmakers, a galosh is also a piece of leather like a welt that runs around the top of the sole between it and the uppers. In Turkish contexts, galoş most often refers to smaller overshoes that are worn indoors to keep from tracking mud or dirt onto

Esquire declared the zipper the "Newest Tailoring Idea for Men", and that among the zippered fly's many virtues was that it would exclude "The Possibility of Unintentional and Embarrassing Disarray." The most recent innovation in the zipper's design was the introduction of models that could open on both ends, as on jackets. The zipper has become by far
3078-514: The industrial revolution , it became increasingly mechanized. In 1765, when a machine for spinning wool or cotton called the spinning jenny was invented in the United Kingdom, textile production became the first economic activity to be industrialised. In the 20th century, science and technology were driving forces. The textile industry exhibits inherent dynamism, influenced by a multitude of transformative changes and innovations within
3159-648: The 14th century, galosh was also being used to refer to English-style clogs , shoes with a wooden sole and a full fabric or leather upper and then to any shoe or boot generally, a meaning it still bears in Azorean Portuguese . From the patten definition, galosh ultimately took on its present meaning of an overshoe worn at sea or in inclement weather. As such, they are also known as overshoes or bad-weather shoes and, now that they are universally made from rubber or rubber-like plastic , may be called rubbers , rubber boots , or gumshoes .

In 1916, newspapers in Australia reported displays of the "new hookless fastener", a device from America that "the world has been waiting for" by a live model in the store window of Raynor's of Melbourne. Gideon Sundbäck increased the number of fastening elements from four per inch (about one every 6.4 mm) to ten or eleven (around every 2.5 mm), introduced two facing rows of teeth that pulled into

The popular North American term zipper (UK zip , or occasionally zip-fastener ) came from the B. F. Goodrich Company in 1923. The company used Gideon Sundbäck's fastener on a new type of rubber boots (or galoshes ) and referred to it as

Textile operations can experience ramifications arising from shifts in international trade policies, evolving fashion trends, evolving customer preferences, variations in production costs and methodologies, adherence to safety and environmental regulations, as well as advancements in research and development. The textile and garment industries exert a significant impact on the economic systems of numerous countries engaged in textile production. Most textiles were called by their base fibre generic names, their place of origin, or were put into groups based loosely on manufacturing techniques, characteristics, and designs. Nylon , olefin , and acrylic are generic names for some of
3726-425: The early 20th century, galoshes have been almost universally made of rubber. Overshoes have evolved in the past decades and now are being made with more advanced features, such as high traction outsoles. There are now only two basic types of galoshes. It is commonly thought that galoshes are known in the United Kingdom as a Wellington boot , a large rubber boot, commonly worn as footwear in their own right, but this
3807-412: The fiber blend composition of mixtures of the fibers, is an important criterion to analyze the behavior, properties such as functional aspects, and commercial classification of the merchandise. The most common blend is cotton and polyester. Regular blended fabric is 65% polyester and 35% cotton. It is called a reverse blend if the ratio of cotton predominates—the percentage of the fibers changes with
3888-402: The fit must be very tight to press the surfaces together firmly. Consequently, these zippers are typically very stiff when zipped shut and have minimal flex or stretch. They are hard to open and close because the zipper anvil must bend apart teeth that are being held under tension. They can also be derailed, causing damage to the sealing surfaces, if the teeth are misaligned while straining to pull
3969-506: The floor. The transition from a traditional wooden sole galosh to one of vulcanized rubber may be attributed to Charles Goodyear and Leverett Candee . The qualities of rubber , though fascinating to Goodyear , were highly dependent on temperature: it was tacky when hot, brittle when cold. Vulcanization of rubber tempered its properties so that it was easily molded, durable, and tough. A rubberized elastic webbing made Goodyear's galoshes ( c. 1890 ) easy to pull on and off. Since

The Universal Fastener Company moved to Hoboken, New Jersey , in 1901, reorganized as the Fastener Manufacturing and Machine Company. Gideon Sundbäck , a Swedish -American electrical engineer , was hired to work for the company in 1906. Good technical skills and marriage to the plant manager's daughter, Elvira Aronson, led Sundbäck to
4293-401: The material to which the rows are attached. The slider, usually operated by hand, contains a Y-shaped channel that, by moving along the rows of teeth, meshes or separates them, depending on the direction of the slider's movement. The teeth may be individually discrete or shaped from a continuous coil, and are also referred to as elements . The word zipper is onomatopoetic , as the device makes

Several textile remnants, such as the Inca Empire's textile arts remnants, which embody the Incas' aesthetics and social ideals, serve as a means for disseminating information about numerous civilizations, customs, and cultures. There are textile museums that display history related to many aspects of textiles. A textile museum raises public awareness and appreciation of

The related words " fabric " and " cloth " and " material " are often used in textile assembly trades (such as tailoring and dressmaking ) as synonyms for textile . However, there are subtle differences in these terms in specialized usage. Material is an extremely broad term basically meaning consisting of matter , and requires context to be useful. A textile
4536-927: The most common of which are for clothing and for containers such as bags and baskets . In the household, textiles are used in carpeting , upholstered furnishings , window shades , towels , coverings for tables, beds, and other flat surfaces, and in art . Textiles are used in many traditional hand crafts such as sewing , quilting , and embroidery . Textiles produced for industrial purposes, and designed and chosen for technical characteristics beyond their appearance, are commonly referred to as technical textiles . Technical textiles include textile structures for automotive applications, medical textiles (such as implants), geotextile (reinforcement of embankments), agrotextiles (textiles for crop protection ), protective clothing (such as clothing resistant to heat and radiation for fire fighter clothing, against molten metals for welders, stab protection, and bullet proof vests). In

The cloth was most likely made by the native Asian people of northwest Romblon . The first clothes, worn at least 70,000 years ago and perhaps much earlier, were probably made of animal skins and helped protect early humans from the elements. At some point, people learned to weave plant fibers into textiles. The discovery of dyed flax fibers in
4860-402: The original design from which the modern device evolved. The zipper gets its name from a brand of rubber boots (or galoshes ) it was used on in 1923. The galoshes could be fastened with a single zip of the hand, and soon the hookless fasteners came to be called "Zippers". A zipper consists of a slider mounted on two rows of metal or plastic teeth that are designed to interlock and thereby join
4941-402: The other and so shaped to act as a "contractible jaw"—the jaw is elastically opened and then closed as it goes over the other tooth. The "snug fit" that results when "one member nests within the recess of an adjoining member" is a stable locked state.

Sundbäck worked on improving the fastener, and, in 1909, he registered a patent in Germany. The US rights to this invention were on the name of the Meadville company (operating as the Hookless Fastener Co.), but Sundbäck retained non-U.S. rights and used these in subsequent years to set up Lightning Fastener Co. in St. Catharines, Ontario, Canada. Sundbäck's work with this firm has led to

Threads coated with zinc oxide nanowires , when woven into fabric, have been shown capable of "self-powering nanosystems", using vibrations created by everyday actions like wind or body movements to generate energy. Textiles are all around us. The textile is a component of basic needs like food and shelter. Textiles are everywhere in our lives, from bath towels to space suits. Textiles help humans by comforting, protecting, and extending their lives. Textiles meet our clothing needs, keeping us warm in
5265-426: The price and required properties. Blending adds value to the textiles; it helps in reducing the cost (artificial fibers are less expensive than natural fibers) and adding advantage in properties of the final product. For instance, a small amount of spandex adds stretch to the fabrics. Wool can add warmth. Fibers from the stalks of plants, such as hemp, flax, and nettles, are also known as 'bast' fibers. Hemp fiber
5346-415: The salt can often be dissolved by submerging the slider in vinegar or another mild acid. Otherwise, the slider needs to be removed and replaced. 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

At the same time this construction gives facility for relative longitudinal movement, without disengagement. The zipper is analogous in function to a drawstring, but different in mechanism. A drawstring works by tension in the string drawing the eyelets of the piece together, since

Those stories reflect "modern anxieties and desires", emphasizing embarrassments and accidents, primarily involving the flies of men's trousers in stories such as "The Unzipped Stranger" and "The Unzipped Fly". In Brave New World , Aldous Huxley repeatedly mentioned zippers, implying that, in their newness (as of the early 1930s), mechanical complexity, ease of use, and speed, zippers were somehow corrosive of natural human values. The zipper
5589-654: The synthetic fiber market will reach 98.21 billion US dollars. From 2022 to 2030, the market is anticipated to increase by 5.1% per year. Monomers are the building blocks of polymers. Polymers in fibers are of two types: additive or condensation. Natural fibers, such as cotton and wool, have a condensation polymer type, whereas synthetic fibers can have either an additive or a condensation polymer type. For example, acrylic fiber and olefin fibers have additive polymers, and nylon and polyester are condensation polymers. Fiber properties influence textile characteristics such as aesthetics, durability, comfort, and cost. Fineness
5670-411: The teeth one-by-one in its "Y-shaped channel", and so, can reversibly lock and unlock them. This is a lock and key design. In Sundback's invention the teeth are symmetric with "exterior and interior rounded surfaces" that are "elongated transversely". The teeth have a material part ("external projection") and a space ("internal recess"). The material part of one tooth is slightly smaller than the space on
5751-411: The tension acts to straighten the string and forces the eyelets toward a line. The zipper works by an elastic , that is, reversible, deformation of the "locking members" (teeth). The zipper teeth are shaped and sized so that the forces which act on the zipper when the garment it is sewn on is worn cannot unlock the teeth. The slider constrains the teeth positions, moves them along a given path, and acts on
5832-490: The tools used for spinning and weaving make up most of the prehistoric evidence for textile work. The earliest tool for spinning was the spindle , to which a whorl was eventually added. The weight of the whorl improved the thickness and twist of the spun thread. Later, the spinning wheel was invented. Historians are unsure where; some say China, others India. The precursors of today's textiles include leaves, barks, fur pelts, and felted cloths. The Banton Burial Cloth,
