78-640: Davol Mills is a historic textile mill complex located at the corner of Plymouth Avenue and Rodman Street in Fall River, Massachusetts . It was built in 1867 and expanded in 1871. It was added to the National Register of Historic Places in 1983 as part of the Corky Row Historic District The red brick mills are unique in the city, built in the Second Empire style. The Davol Mills Company
156-510: A cotton gin . The cotton gin separates seeds and removes the "trash" (dirt, stems and leaves) from the fibre. In a saw gin, circular saws grab the fibre and pull it through a grating that is too narrow for the seeds to pass. A roller gin is used with longer-staple cotton. Here, a leather roller captures the cotton. A knife blade, set close to the roller, detaches the seeds by drawing them through teeth in circular saws and revolving brushes which clean them away. The ginned cotton fibre, known as lint,
234-405: A patent of his cotton gin on October 28, 1793; the patent was granted on March 14, 1794, but was not validated until 1807. Whitney's patent was assigned patent number 72X. There is slight controversy over whether the idea of the modern cotton gin and its constituent elements are correctly attributed to Eli Whitney. The popular image of Whitney inventing the cotton gin is attributed to an article on
312-404: A cone-shaped bundle of fibres known as a "cop", as the carriage returns. Mule spinning produces a finer thread than ring spinning . The mule was an intermittent process, as the frame advanced and returned a distance of five feet. It was the descendant of the 1779 Crompton device. It produces a softer, less twisted thread that was favoured for fine fabrics and wefts. The ring was a descendant of
390-470: A continuous soft fleecy sheet, known as a lap. Scutching refers to the process of cleaning cotton of its seeds and other impurities. The first scutching machine was invented in 1797, but did not come into further mainstream use until after 1808 or 1809, when it was introduced and used in Manchester, England. By 1816, it had become generally adopted. The scutching machine worked by passing the cotton through
468-424: A loose strand (sliver or tow). The cotton comes off of the picking machine in laps, and is then taken to carding machines. The carders line up the fibres neatly to make them easier to spin. The carding machine consists mainly of one big roller with smaller ones surrounding it. All of the rollers are covered in small teeth, and as the cotton is moved forwards, the teeth get finer (i.e. closer together). The cotton leaves
546-424: A machine with large spikes, called an opener . To fluff up the cotton and remove the vegetable matter, the cotton is sent through a picker or a similar machine. In a picker , the cotton is beaten with a beater bar to loosen it up. It is then fed through various rollers, which serve to remove the vegetable matter. The cotton, aided by fans, then collects on a screen and gets fed through more rollers where it emerges as
624-485: A modified Forbes version, one man and a boy could produce 250 pounds per day. If oxen were used to power 16 of these machines, and a few people's labor was used to feed them, they could produce as much work as 750 people did formerly. The Indian roller cotton gin, known as the churka or charkha , was introduced to the United States in the mid-18th century, when it was adopted in the southern United States . The device
702-445: A pair of rollers, and then striking it with iron or steel bars called beater bars or beaters. The beaters, which turn very quickly, strike the cotton hard and knock the seeds out. This process is done over a series of parallel bars so as to allow the seeds to fall through. At the same time, air is blown across the bars, which carries the cotton into a cotton chamber. In the carding process, the fibres are separated and then assembled into
780-415: A plain loom. A Northrop Loom was fully automatic and was mass-produced between 1909 and the mid-1960s. Modern looms run faster and do not use a shuttle: there are air jet looms, water jet looms, and rapier looms . Ends and Picks: Picks refer to the weft, ends refer to the warp. The coarseness of the cloth can be expressed as the number of picks and ends per quarter-inch square, or per inch square. Ends
858-418: A result, the region became even more dependent on plantations that used black slave labor, with plantation agriculture becoming the largest sector of its economy. While it took a single laborer about ten hours to separate a single pound of fiber from the seeds, a team of two or three slaves using a cotton gin could produce around fifty pounds of cotton in just one day. The number of slaves rose in concert with
SECTION 10
#1733084780428936-469: A single roller made of iron or wood and a flat piece of stone or wood. The earliest evidence of the cotton gin is found in the fifth century, in the form of Buddhist paintings depicting a single-roller gin in the Ajanta Caves in western India . These early gins were difficult to use and required a great deal of skill. A narrow single roller was necessary to expel the seeds from the cotton without crushing
1014-404: A small scale. Whitney's gin is made with two rotating cylinders. The first cylinder has lines of teeth around the circumference, and angled against this cylinder is a metal plate with small holes, "ginning ribs", through which the teeth can fit with minimal gaps. The teeth grip the cotton fibers as the mechanism rotates, dragging them through these small holes. The seeds are too big to fit through
1092-421: A system gin, and obtained related patents. The Munger System Ginning Outfit (or system gin) integrated all the ginning operation machinery, thus assuring the cotton would flow through the machines smoothly. Such system gins use air to move cotton from machine to machine. Munger's motivation for his inventions included improving employee working conditions in the gin. However, the selling point for most gin owners
1170-413: A very thick rope of cotton fibres, the slivers are separated into rovings. Generally speaking, for machine processing, a roving is about the width of a pencil. These rovings (or slubbings) are then what are used in the spinning process. Most spinning today is done using break, or open-end spinning . This is a technique where the fibres are blown by air into a rotating drum, where they attach themselves to
1248-452: Is a major industry . It is largely based on the conversion of fibre into yarn , then yarn into fabric. These are then dyed or printed, fabricated into cloth which is then converted into useful goods such as clothing , household items, upholstery and various industrial products. Different types of fibres are used to produce yarn. Cotton remains the most widely used and common natural fiber making up 90% of all-natural fibers used in
1326-488: Is a weft knit. Finishing is a broad range of physical and chemical processes/treatments that complete one stage of textile manufacturing, sometimes in preparation for the next step. Finishing adds value to the product and makes it more attractive, useful and functional for the end-user. Fresh off the loom, cotton fabric not only contains impurities, including warp size, but it also requires further treatment to develop its full potential and to add to its value. Depending on
1404-433: Is always written first. For example: Heavy domestics are made from coarse yarns, such as 10's to 14's warp and weft, and about 48 ends and 52 picks. Associated job titles include piecer, scavenger , weaver, tackler , draw boy. When a hand loom was located in the home, children helped with the weaving process from an early age. Piecing needs dexterity, and a child can be as productive as an adult. When weaving moved from
1482-470: Is boiled in an alkali solution, which forms a soap with free fatty acids. A kier is usually enclosed, so the solution of sodium hydroxide can be boiled under pressure, excluding oxygen , which would degrade the cellulose in the fibre. If the appropriate reagents are used, scouring will also remove size from the fabric, although desizing often precedes scouring and is considered to be a separate process. Preparation and scouring are prerequisites to most of
1560-404: Is called Indian. The cotton seed is pressed into cooking oil. The husks and meal are processed into animal feed, and the stems into paper. Ginning, bale-making and transportation are done in the country of origin. Cotton is shipped to mills in large 500-pound bales. When the cotton comes out of a bale, it is all packed together and still contains vegetable matter. The bale is broken open using
1638-502: Is considered to be 'A Treatise on the Art of Weaving' by John Murphy. Cotton is the world's most important natural fibre. In the year 2007, the global yield was 25 million tons from 35 million hectares cultivated in more than 50 countries. There are six stages to the manufacturing of cotton textiles: Cotton is grown in locations with long, hot, dry summers with plenty of sunshine and low humidity. Indian cotton, Gossypium arboreum ,
SECTION 20
#17330847804281716-404: Is done by pulling yarn from two or more bobbins and twisting it together, in a direction opposite to the one it was spun in. Depending on the weight desired, the cotton may or may not be plied, and the number of strands twisted together varies. Gassing is the process of passing yarn very rapidly through a series of Bunsen gas flames in a gassing frame, to burn off the projecting fibres and to make
1794-480: Is done in two different ways; warp and weft. Weft knitting (as seen in the pictures) is similar in method to hand knitting with stitches all connected to each other horizontally. Various weft machines can be configured to produce textiles from a single spool of yarn or multiple spools, depending on the size of the machine cylinder (in which the needles are bedded). In a warp knit , there are many pieces of yarn and there are vertical chains, zigzagged together by crossing
1872-417: Is finer but the staple is only suitable for hand processing. American cotton, Gossypium hirsutum , produces the longer staple needed for mechanised textile production. The planting season is from September to mid-November, and the crop is harvested between March and June. The cotton bolls are harvested by stripper harvesters and spindle pickers that remove the entire boll from the plant. The cotton boll
1950-461: Is mercerised under tension, and all alkali must be washed out before the tension is released, or shrinkage will take place. Many other chemical treatments may be applied to cotton fabrics to produce low flammability, crease-resistance and other qualities, but the four most important non-chemical finishing treatments are: Singeing is designed to burn off the surface fibres from the fabric to produce smoothness. The fabric passes over brushes to raise
2028-472: Is the application of colour in the form of a paste or ink to the surface of a fabric in a predetermined pattern. It can be described as a form of localised dyeing. Printing designs onto previously dyed fabric is also possible. Production of cotton requires arable land . In addition, cotton is farmed intensively and uses large amounts of fertilizer and 25% of the world's insecticides. Native Indian varieties of cotton were rainwater fed, but modern hybrids used for
2106-498: Is the seed pod of the cotton plant; attached to each of the thousands of seeds are fibres about 2.5 cm long. There is a higher rate of cotton being produced compared to the actual workers needed to produce the material. In 2013 a cotton farmer in Mississippi, Bower Flowers, produced around 13,000 bales of cotton in that year alone. This amount of cotton could be used to produce up to 9.4 million T-shirts. The seed cotton goes into
2184-419: Is then compressed into bales which are about 1.5 m tall and weigh almost 220 kg. Only 33% of the crop is usable lint. Commercial cotton is graded and priced according to its quality; this broadly relates to the average length of the staple and the variety of the plant. Longer-staple cotton (2½ in to 1¼ in) is called Egyptian, medium staple (1¼ in to ¾ in) is called American upland, and short staple (less than ¾ in)
2262-479: The Indian subcontinent since at earliest AD 500 and then in other regions. The Indian worm-gear roller gin was invented sometime around the 16th century and has, according to Lakwete, remained virtually unchanged up to the present time. A modern mechanical cotton gin was created by American inventor Eli Whitney in 1793 and patented in 1794. Whitney's gin used a combination of a wire screen and small wire hooks to pull
2340-487: The crank handle in the cotton gin, first appeared sometime during the late Delhi Sultanate or the early Mughal Empire. The incorporation of the worm gear and crank handle into the roller cotton gin led to greatly expanded Indian cotton textile production during the Mughal era. It was reported that, with an Indian cotton gin, which is half machine and half tool, one man and one woman could clean 28 pounds of cotton per day. With
2418-422: The weft . The warp, which must be strong, needs to be presented to loom on a warp beam. The weft passes across the loom in a shuttle that carries the yarn on a pirn . These pirns are automatically changed by the loom. Thus, the yarn needs to be wrapped onto a beam, and onto pirns before weaving can commence. After being spun and plied, the cotton thread is taken to a warping room where the winding machine takes

2496-522: The 16th century. This mechanical device was, in some areas, driven by waterpower. The worm gear roller gin, which was invented in the Indian subcontinent during the early Delhi Sultanate era of the 13th to 14th centuries, came into use in the Mughal Empire sometime around the 16th century, and is still used in the Indian subcontinent through to the present day. Another innovation, the incorporation of
2574-474: The American Civil War. In modern cotton production, cotton arrives at industrial cotton gins either in trailers, in compressed rectangular " modules " weighing up to 10 metric tons each or in polyethylene wrapped round modules similar to a bale of hay produced during the picking process by the most recent generation of cotton pickers. Trailer cotton (i.e. cotton not compressed into modules) arriving at
2652-469: The Arkwright Water frame of 1769. It was a continuous process, the yarn was coarser, had a greater twist and was stronger, thus suitable for use as warp thread. Ring spinning is slow due to the distance the thread must pass around the ring. Sewing thread was made of several threads twisted together, or doubled. This is the process where each of the bobbins is rewound to give a tighter bobbin. Plying
2730-529: The South. Additionally, the greatly expanded supply of cotton created strong demand for textile machinery and improved machine designs that replaced wooden parts with metal. This led to the invention of many machine tools in the early 19th century. The invention of the cotton gin caused massive growth in the production of cotton in the United States, concentrated mostly in the South. Cotton production expanded from 750,000 bales in 1830 to 2.85 million bales in 1850. As
2808-513: The art and craft industries. Until the 18th and 19th centuries, the textile industry was a household work. It became mechanised in the 18th and 19th centuries, and has continued to develop through science and technology since the twentieth century. Specifically, ancient civilizations in India, Egypt, China, sub-Saharan Africa, Eurasia, South America, and North and East Africa all had some forms of textile production. The first book about textile manufacturing
2886-422: The carding machine in the form of a sliver: a large rope of fibres. In a wider sense, carding can refer to these four processes: Combing is optional, but is used to remove the shorter fibres, creating a stronger yarn. Several slivers are combined. Each sliver will have thin and thick spots, and by combining several slivers together, a more consistent size can be reached. Since combining several slivers produces
2964-522: The cleaning of seeds from short-staple cotton, it damaged the fibers of extra-long staple cotton ( Gossypium barbadense ). In 1840 Fones McCarthy received a patent for a "Smooth Cylinder Cotton-gin", a roller gin. McCarthy's gin was marketed for use with both short-staple and extra-long staple cotton but was particularly useful for processing long-staple cotton. After McCarthy's patent expired in 1861, McCarthy type gins were manufactured in Britain and sold around
3042-444: The cotton gin by 1796. However, the evidence indicates Whitney did invent the saw gin, for which he is famous. Although he spent many years in court attempting to enforce his patent against planters who made unauthorized copies, a change in patent law ultimately made his claim legally enforceable – too late for him to make much money from the device in the single year remaining before the patent expired. While Whitney's gin facilitated
3120-454: The cotton gin led to an increase in the use of slaves on Southern plantations. Because of that inadvertent effect on American slavery, which ensured that the South's economy developed in the direction of plantation-based agriculture (while encouraging the growth of the textile industry elsewhere, such as in the North), the invention of the cotton gin is frequently cited as one of the indirect causes of
3198-569: The cotton is held by rapidly rotating saw cylinders. The gin stand uses the teeth of rotating saws to pull the cotton through a series of "ginning ribs", which pull the fibers from the seeds which are too large to pass through the ribs. The cleaned seed is then removed from the gin via an auger conveyor system. The seed is reused for planting or is sent to an oil mill to be further processed into cottonseed oil and cottonseed meal . The lint cleaners again use saws and grid bars, this time to separate immature seeds and any remaining foreign matter from

3276-472: The cotton through, while brushes continuously removed the loose cotton lint to prevent jams. It revolutionized the cotton industry in the United States, but also inadvertently led to the growth of slavery in the American South . Whitney's gin made cotton farming more profitable and efficient so plantation owners expanded their plantations and used more of their slaves to pick cotton. Whitney never invented
3354-422: The cotton yarn. Warp knits do not stretch as much as a weft knits, and they are run-resistant. A weft knit is not run-resistant, but it has more stretch. This is especially true if spools of elastane are processed from separate spool containers and interwoven through the cylinder with cotton yarn, giving the finished product more flexibility and preventing it from having a 'baggy' appearance. The average t-shirt
3432-478: The culmination of what geographer Charles S. Aiken has termed the second ginning revolution, in which the privately owned plantation gins were replaced by large-scale public ginneries. This revolution, in turn, led to a major restructuring of the cotton gin industry, as the small, scattered gin factories and shops of the nineteenth century gave way to a dwindling number of large twentieth-century corporations designing and constructing entire ginning operations." One of
3510-504: The dents of the reed and the eyes of the healds, in the order indicated by the draft. A pirn-winding frame was used to transfer the weft from cheeses of yarn onto the pirns that would fit into the shuttle. At this point, the thread is woven. Depending on the era, one person could manage anywhere from 3 to 100 machines. In the mid-nineteenth century, four was the standard number. A skilled weaver in 1925 could run 6 Lancashire Looms . As time progressed, new mechanisms were added that stopped
3588-410: The fabric is to be dyed a deep shade, then lower levels of bleaching are acceptable. However, for white bedding and for medical applications, the highest levels of whiteness and absorbency are essential. A further possibility is mercerising, during which the fabric is treated with a caustic soda solution, to cause swelling of the fibres. This results in improved lustre, strength and dye affinity. Cotton
3666-403: The fabric will shrink less upon laundering. Dyeing is commonly carried out with an anionic direct dye by completely immersing the fabric (or yarn) in an aqueous dye bath according to a prescribed procedure. For improved fastness to washing, rubbing and light, further dyeing methods can be used. These require more complex chemistry during processing, and are thus more expensive to apply. Printing
3744-713: The few (and perhaps only) examples of a Munger gin left in existence is on display at Frogmore Plantation in Louisiana. Prior to the introduction of the mechanical cotton gin, cotton had required considerable labor to clean and separate the fibers from the seeds. With Eli Whitney's gin, cotton became a tremendously profitable business, creating many fortunes in the Antebellum South . Cities such as New Orleans, Louisiana ; Mobile, Alabama ; Charleston, South Carolina ; and Galveston, Texas became major shipping ports, deriving substantial economic benefit from cotton raised throughout
3822-425: The fibers ("lint") in the bolls are tightly interwoven with seeds. To make the fibers usable, the seeds and fibers must first be separated, a task which had been previously performed manually, with production of cotton requiring hours of labor for the separation. Many simple seed-removing devices had been invented, but until the innovation of the cotton gin, most required significant operator attention and worked only on
3900-412: The fibers. The bale press then compresses the cotton into bales for storage and shipping. Modern gins can process up to 15 tonnes (33,000 lb) of cotton per hour. A single-roller cotton gin came into use in India by the 5th century. An improvement invented in India was the two-roller gin, known as the "churka", "charki", or "wooden-worm-worked roller". The earliest versions of the cotton gin consisted of

Modern cotton gins create a substantial amount of cotton gin residue (CGR) consisting of sticks, leaves, dirt, immature bolls, and cottonseed. Research is currently under way to investigate the use of this waste in producing ethanol . Due to fluctuations in

During raising, the fabric surface is treated with sharp teeth to lift the surface fibres, thereby imparting downiness, softness and warmth, as in flannelette. Calendering is a process in which the fabric is passed between heated rollers to generate smooth, polished or embossed effects. Sanforisation is a form of mechanical pre-shrinking, so that
4134-438: The gin is sucked in via a pipe, approximately 16 inches (41 cm) in diameter, that is swung over the cotton. This pipe is usually manually operated but is increasingly automated in modern cotton plants. The need for trailers to haul the product to the gin has been drastically reduced since the introduction of modules. If the cotton is shipped in modules, the module feeder breaks the modules apart using spiked rollers and extracts
4212-469: The gin stand ran smoothly, a condenser to make the clean cotton coming out of the gin easier to handle, and indoor presses so that cotton no longer had to be carried across the gin yard to be baled. Then, in 1879, while he was running his father's gin in Rutersville, Texas , Robert S. Munger invented additional system ginning techniques. Robert and his wife, Mary Collett, later moved to Mexia, Texas , built
4290-575: The holes, and are thus removed from the rotating cotton by the metal plate, before they fall into a collecting pot. On the other side of the first cylinder, there is a second cylinder, also rotating, with brushes attached. This second cylinder wipes the cotton from the first, and deposits it into the collecting bucket. The seed is reused for planting or is sent to an oil mill to be further processed into cottonseed oil and cottonseed meal . The lint cleaners again use saws and grid bars, this time to separate immature seeds and any remaining foreign matter from
4368-878: The home to the mill, children were often allowed to help their older sisters, and laws had to be made to prevent child labour from becoming established. The working conditions of cotton production were often harsh, with long hours, low pay, and dangerous machinery. Children, above all, were also prone to physical abuse and often forced to work in unsanitary conditions. It should also be noted that Children who worked in handlooms often faced extreme poverty and were unable to obtain an education.

Children, above all, were also prone to physical abuse and often forced to work in unsanitary conditions. It should also be noted that Children who worked in handlooms often faced extreme poverty and were unable to obtain an education. Knitting by machine
4446-496: The increase in cotton production, increasing from around 700,000 in 1790 to around 3.2 million in 1850. The invention of the cotton gin led to increased demands for slave labor in the American South , reversing the economic decline that had occurred in the region during the late 18th century. The cotton gin thus "transformed cotton as a crop and the American South into the globe's first agricultural powerhouse". The invention of
4524-525: The largest pieces of foreign material from the cotton. The module feeder's loose cotton is then sucked into the same starting point as the trailer cotton. The cotton then enters a dryer, which removes excess moisture. The cylinder cleaner uses six or seven rotating, spiked cylinders to break up large clumps of cotton. Finer foreign material, such as soil and leaves, passes through rods or screens for removal. The stick machine uses centrifugal force to remove larger foreign matter, such as sticks and burrs, while

Forty of these Northrop Looms or automatic looms could be operated by one skilled worker. The three primary movements of a loom are shedding, picking, and beating-up. The Lancashire Loom was the first semi-automatic loom. Jacquard looms and Dobby looms are looms that have sophisticated methods of shedding. They may be separate looms or mechanisms added to
4680-482: The machine to harvest cotton: it still had to be picked by hand. The invention has thus been identified as an inadvertent contributing factor to the outbreak of the American Civil War . Modern automated cotton gins use multiple powered cleaning cylinders and saws, and offer far higher productivity than their hand-powered precursors. Cotton fibers are produced in the seed pods ("bolls") of the cotton plant where

Cotton gin A cotton gin —meaning "cotton engine " —is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation. The separated seeds may be used to grow more cotton or to produce cottonseed oil . Handheld roller gins had been used in

A series of brushes on a second rotating cylinder then brushed the now-cleaned fibers loose from the wires, preventing the mechanism from jamming. Many contemporary inventors attempted to develop a design that would process short staple cotton , and Hodgen Holmes, Robert Watkins, William Longstreet , and John Murray had all been issued patents for improvements to
4914-491: The other finishing processes. At this stage, even the most naturally white cotton fibres are yellowish, and bleaching is required. Bleaching improves whiteness by removing natural colouration and whatever impurities remain in the cotton; the degree of bleaching is determined by the levels of whiteness and absorbency required of the fabric. Cotton, being a vegetable fibre, is bleached using an oxidizing agent , such as diluted sodium hypochlorite or diluted hydrogen peroxide . If

Because the thread is fine, often three of these would be combined to get the desired number of ends. A sizing machine is needed for strengthening the warp by adding starch, to reduce breakage. The process of drawing each end of the warp separately through
5070-408: The roving is pulled off a bobbin and fed through rollers, which are feeding at several different speeds. This thins the roving at a consistent rate. If the roving was not a consistent size, then this step could cause a break in the yarn, or jam the machine. The yarn is twisted through the spinning of the bobbin as the carriage moves out, and is rolled onto a cylinder called a spindle, which then produces
5148-464: The seeds. The design was similar to that of a mealing stone , which was used to grind grain. The early history of the cotton gin is ambiguous, because archeologists likely mistook the cotton gin's parts for other tools. Between the 12th and 14th centuries, dual-roller gins appeared in India and China. The Indian version of the dual-roller gin was prevalent throughout the Mediterranean cotton trade by

Scouring is a chemical washing process carried out on cotton fabric to remove natural waxes and non-fibrous impurities (like the remains of seed fragments) from the fibres and any soiling or dirt that might remain. Scouring is usually carried out in iron vessels called kiers . The fabric
5304-603: The speed at which the gin could operate. In the middle of the 20th Century gins using a rotating blade replaced ones using a reciprocating blade. These descendants of the McCarthy gin are the only gins now used for extra-long staple cotton in the United States. For a decade and a half after the end of the Civil War in 1865, a number of innovative features became widely used for ginning in the United States. They included steam power instead of animal power, an automatic feeder to assure that
5382-452: The subject written in the early 1870s and later reprinted in 1910 in The Library of Southern Literature . In this article, the author claimed Catharine Littlefield Greene suggested to Whitney the use of a brush-like component instrumental in separating out the seeds and cotton. Greene's alleged role in the invention of the gin has not been verified independently. Whitney's cotton gin model

This method has replaced the older methods of ring and mule spinning. It is also easily adapted for artificial fibres . The spinning machines takes the roving, thins it and twists it, creating yarn which it winds onto a bobbin. In mule spinning

There are many variable processes available at the spinning and fabric-forming stages coupled with the complexities of the finishing and colouration processes to the production of a wide range of products. Textile manufacturing in the modern era is an evolved form of

Only the better qualities of yarn are gassed, like the kinds used for voiles, poplins, venetians, gabardines, Egyptian cottons, etc. The thread loses around 5-8% of its weight if it's gassed. The gassed yarn is darker in shade afterwards, but should not be scorched. The weaving process uses a loom . The lengthwise threads are known as the warp , and the crosswise threads are known as
5694-513: The world. McCarthy's gin was adopted for cleaning the Sea Island variety of extra-long staple cotton grown in Florida, Georgia and South Carolina. It cleaned cotton several times faster than the older gins, and, when powered by one horse, produced 150 to 200 pounds of lint a day. The McCarthy gin used a reciprocating knife to detach seed from the lint. Vibration caused by the reciprocating motion limited

Several modifications were made to the Indian roller gin by Mr. Krebs in 1772 and Joseph Eve in 1788, but their uses remained limited to the long-staple variety, up until Eli Whitney's development of a short-staple cotton gin in 1793. Eli Whitney (1765–1825) applied for
