Drawing Slubbing Intermediate Roving Fine Roving Mule Spinning Ring Spinning Spinning Reeling Doubling Winding Bundling Bleaching Winding Warping Cabling Sizing Slashing Dressing Gassing Weaving Spooling Cloth Yarn Cheese Bundle Sewing Thread 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 five stages Cultivating and Harvesting Preparatory Processes Spinning Weaving Finishing Cultivating and harvesting Cotton is grown anywhere with long hot dry summers with plenty of sunshine and low humidity Indian cotton gossypium arboreum is finer but the staple is only suitable for hand processing American cotton gossypium hirsutum produces the longer staple needed for machine production Planting is from September to mid November and the crop is harvested between March and May The cotton bolls are harvested by stripper harvesters and spindle pickers that remove the entire boll from the plant The cotton boll is the seed pod of the cotton plant attached to each of the thousands of seeds are fibres about 2 5 160 cm long Ginning The seed cotton goes in to 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 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 priced by quality and that broadly relates to the average length of the staple and the variety of the plant Longer staple cotton 2 in to 1 in is called Egyptian medium staple 1 in to in is called American upland and short staple less than in is called Indian The cotton seed is pressed into a cooking oil The husks and meal are processed into animal feed and the stems into paper Issues Cotton is farmed intensively and uses large amounts of fertiliser and 25 of the worlds insecticide Native Indian variety were rainwater fed but modern hybrids used for the mills need irrigation which spreads pests The 5 of cotton bearing land in India uses 55 of all pesticides used in India Before mechanisation cotton was harvested manually and this unpleasant task was done by the lower castes and in the United States by slaves of African origin Preparatory Processes Preparation of yarn Ginning bale making and transportation is done in the country of origin Opening and cleaning Platt Bros Picker Cotton mills get the cotton shipped to them 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 a machine with large spikes It is called an Opener In order to fluff up the cotton and remove the vegetable matter the cotton is sent through a picker or similar machines A picker looks similar to the carding machine and the cotton gin but is slightly different The cotton is fed into the machine and gets beaten with a beater bar to loosen it up It is 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 till it emerges as a continuous soft fleecy sheet known as a lap Blending Mixing amp Scutching Carding Main article Carding Carding machine Carding the fibres are separated and then assembled into a loose strand sliver or tow at the conclusion of this stage The cotton comes off of the picking machine in laps and is then taken to carding machines The carders line up the fibres nicely 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 progresses further on the teeth get finer i e closer together The cotton leaves the carding machine in the form of a sliver a large rope of fibres Note In a wider sense Carding can refer to these four processes Willowing loosening the fibres Lapping removing the dust to create a flat sheet or lap of cotton Carding combing the tangled lap into a thick rope of 1 2 in in diameter a sliver and Drawing where a drawing frame combines 4 slivers into one repeated for increased quality Combing is optional but is used to remove the shorter fibres creating a stronger yarn A Combing machine Drawing the fibres are straightened 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 a very thick rope of cotton fibres directly after being combined the slivers are separated into rovings These rovings are then what are used in the spinning process Generally speaking for machine processing a roving is about the width of a pencil Next 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 a very thick rope of cotton fibres directly after being combined the slivers are separated into rovings These rovings or slubbings are then what are used in the spinning process Generally speaking for machine processing a roving is about the width of a pencil Drawing frame Draws the strand out Slubbing Frame adds twist and winds on to bobbins Intermediate Frames are used to repeat the slubbing process to produce a finer yarn Roving frames reduces to a finer thread gives more twist makes more regular and even in thickness and winds on to a smaller tube Spinning Yarn manufacture Main article Cotton spinning machinery Spinning The spinning machines take the roving thins it and twists it creating yarn which it winds onto a bobbin In mule spinning the roving is pulled off a bobbin and fed through some 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 could jam the machine The yarn is twisted through the spinning of the bobbin as the carriage moves out and is rolled onto a cop as the carriage returns Mule spinning produces a finer thread than the less skilled ring spinning The mule was an intermittent process as the frame advanced and returned a distance of 5ft It was the descendant of 1779 Crompton device It produces a softer less twisted thread that was favoured for fines and for weft It requires considerable skill so was womens work The ring was a descendant of the Arkwright water Frame 1769 It was a continuous process the yard was coarser had a greater twist and was stronger so was suited to be warp Requiring less skill it was mens work Ring spinning is slow due to the distance the thread must pass around the ring other methods have been introduced These are collectively known as Break or Open end spinning Sewing thread was made of several threads twisted together or doubled Checking This is the process where each of the bobbins is rewound to give a tighter bobbin Folding and twisting Plying is done by pulling yarn from two or more bobbins and twisting it together in the opposite direction that that in which it was spun Depending on the weight desired the cotton may or may not be plied and the number of strands twisted together varies Gassing Main articles Singe Textiles and Gassing Gassing is the process of passing yarn as distinct from fabric very rapidly through a series of Bunsen gas flames in a gassing frame in order to burn off the projecting fibres and make the thread round and smooth and also brighter Only the better qualities of yarn are gassed such as that used for voiles poplins venetians gabardines many Egyptian qualities etc There is a loss of weight in gassing which varies about 5 to 8 per cent so that if a 2 60 s yarn is required 2 56 s would be used The gassed yarn is darker in shade afterwards but should not be scorched Mule spinning Mule spinning Ring spinning Ring spinning Measurements Main article Units of textile measurement Cotton Counts The number of pieces of thread 840 yards long needed to make up 1 lb weight 10 count cotton means that 10x840 yd weighs 1 lb This is coarser than 40 count cotton where 40x840 yards are needed In the United Kingdom Counts to 40s are coarse Oldham Counts 40 to 80s are medium counts and above 80 is a fine count In the United States ones to 20s are coarse counts Hank A length of 7 leas or 840 yards Thread A length of 54 in the circumference of a warp beam Bundle Usually 10 lb Lea A length of 80 threads or 120 yards Denier this is an alternative method It is defined as a number that is equivalent to the weight in grams of 9000m of a single yarn 15 denier is finer than 30 denier Tex is the weight in grams of 1 160 km of yarn The worsted hank is only 560 yd Weaving fabric manufacture The weaving process uses a loom The lengthway threads are known as the warp and the cross way threads are known as 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 Winding After being spun and plied the cotton thread is taken to a warping room where the winding machine takes the required length of yarn and winds it onto warpers bobbins Warping or beaming A Warper Racks of bobbins are set up to hold the thread while it is rolled onto the warp bar of a loom Because the thread is fine often three of these would be combined to get the desired thread count citation needed Sizing Slasher sizing machine needed for strengthening the warp by adding starch Drawing in Looming The process of drawing each end of the warp separately through the dents of the reed and the eyes of the healds in the order indicated by the draft Pirning Processing the weft Pirn winding frame was used to transfer the weft from cheeses of yarn onto the pirns that would fit into the shuttle Weaving Main article Power loom 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 would run 6 Lancashire Looms As time progressed new mechanisms were added that stopped the loom any time something went wrong The mechanisms checked for such things as a broken warp thread broken weft thread the shuttle going straight across and if the shuttle was empty Forty of these Northrop Looms or automatic looms could be operated by one skilled worker A Draper loom in textile museum Lowell Massachusetts The three primary movements of a loom are shedding picking and beating up Shedding The operation of dividing the warp into two lines so that the shuttle can pass between these lines There are two general kinds of sheds open and closed Open Shed The warp threads are moved when the pattern requires it from one line to the other Closed Shed The warp threads are all placed level in one line after each pick Picking The operation of projecting the shuttle from side to side of the loom through the division in the warp threads This is done by the overpick or underpick motions The overpick is suitable for quick running looms whereas the underpick is best for heavy or slow looms Beating up The third primary movement of the loom when making cloth and is the action of the reed as it drives each pick of weft to the fell of the cloth 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 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 Measurements 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 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 Piecer Scavenger Weaver Tackler Draw boy Pirner Issues 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 moves from the home to the mill children were often allowed to help their older sisters and laws have to be made to prevent child labour becoming established Knitting Fabric manufacture A circular knitting machine Close up on the needles Knitting by machine is done in two different ways warp and weft Weft knitting as seen in the pictures is similar in method to hand
