Cotton roll is made through Comb preparation procedure again, the good cotton yarn of fibre length consistency is made through combing process again for cotton roll,
Cotton yarn is then fed into the drawing frame with autoleveller, the cotton ripe bar of uniform quality is made through one of mixing in doubling step,
Cotton rove quantitative smaller and with the smaller twist is made through Roving Frames in cotton ripe bar again, cotton rove is made through spinning process
The final required high branch cylinder of pure cotton combed is made through winding procedure in cotton coil by cotton coil quantitative smaller and with the larger twist
Yarn.
To realize the above-mentioned production for washing pure cotton combed high grade cotton yarn, the present invention uses following production method, including following step
It is rapid:
The first step, by cotton packet being emitted on front side of full-automatic reciprocating type griping cotton machine and on the conveyer belt of rear side in proportion, warp
The suction type of full-automatic reciprocating type griping cotton machine is grabbed cotton head and is moved along back and forth shuttle of conveyer belt, so that biography will be placed on
It send the cotton fiber in the cotton packet taken under the suction of negative pressure by crawl in proportion, when grabbing cotton, grabs cotton head using double and grab cotton sieve
It draws, while hired roughneck's blade is retracted rib 3mm, it is ensured that the cotton block grabbed every time is smaller, and it is further that it is caducous few broken, which to be conducive to impurity,
Shredding lay a good foundation；The mixing cotton fiber grabbed in proportion is transmitted in heavy object separator by transfer pipeline, in weight
In object separator, it is provided with magnet arrangement and negative pressure device, thus by the weight of ferrous metal mixed in cotton fiber etc. by magnetic
Iron attracts and separates exclusion with cotton fiber, while to the biggish blocky impurity such as non-ferrous weight, miscellaneous using hard such as weights
The difference in the path that the flexible materials such as matter and fiber move in negative pressure gas flow, thus by non-ferrous weight mixed in cotton fiber
Object impurity separates exclusion with cotton fiber, thus finally will be biggish in the cotton fiber grabbed by griping cotton machine in heavy object separator
Impurity is removed；The suction that the cotton fiber of pipeline output through heavy object separator then passes through condenser is fed into single axial stream opener
In machine, cotton-slitting beater is provided in Single axial waste silk opener, the cotton fiber of feeding realizes free shape under the action of cotton-slitting beater
Strike effect under state, thus by mainly being struck with big flock existing for biggish bulk form at lesser piece in cotton fiber
Lower flock existing for shape form, and since cotton fiber is to be hit shredding in a free state, can cotton-slitting beater compared with
It is realized under big impact force and the flexibility of cotton fiber is hit, to reduce the damage to cotton fiber in the shots to cotton fiber
Wound effect carries out shredding, except living together using the area Luo Za of roller frame, V-type elasticity brad hired roughneck, four groups of triangle dirt sticks composition
Reason；The cotton fiber exported through Single axial waste silk opener is then fed into multi-mixer, and 3-5 is provided in multi-mixer
A high hopper, under airflow function, cotton fiber is equably blown into each cotton storehouse, forms moment random mixing effect for the first time,
Fiber in each hopper is conveyed through 90 degree of turnings, and is converged again at point, since the cotton fiber in each hopper enters
The length in path experienced is different when to point, to realize in the cotton fiber of mixture between a variety of different cotton fibers
Second of path difference immixture, while under the cutting crawl and the shredding counterattack of evener roller effect of brad curtain, form third
Secondary tumble mixed effect, while being provided in the equipped at outlet port of hopper and giving cotton roller, thus sending cotton roller to rotate cotton fiber
The lesser blocky impurity in cotton fiber is further separated into removing during conveying；Cotton through multi-mixer output is fine
Dimension is then fed into main de-burring machine, and hopper is provided with before main de-burring machine, and main de-burring machine is used to comb the method that generation beats, warp
The small flock that opener shredding acts on enters hopper after hired roughneck's shredding, passes through transferring roller, big combing roller, mote knife, support
The collective effect of cotton plate etc., realizes further careful shredding and the efficient impurity removal of small flock, and when use defers to " thin feeding, light
The technological principle of shredding, high transfer, removal of impurities height, few damage "；The cotton fiber exported through main de-burring machine, which is then sequentially fed into, to be removed
In micronic dust machine and different fine separator, thus by the more tiny blocky impurity or flexible impurity in cotton fiber in except micronic dust machine
Separation is removed, other fibers mixed in cotton fiber are carried out separation removing in different fine separator；Complete fine impurities and different
Property the cotton fiber removed of fiber be then fed into carding machine, be provided with hopper on rear side of carding machine, cotton fiber first by
It is sent in the hopper of carding machine, the negative pressure pressure of the hopper of carding machine is set as 60Pa, and cotton layer is maintained at hopper height
Between 39%-41%, thus by the cotton fiber of feeding to be constantly fed into cotton carding after quality and cotton in homogeneous thickness layer output
In machine, cotton is uniformly fed to carding machine to realize, cotton carding uses the principle of " big gauge, light quantitative, jogging speed ", in carding machine
To cotton fiber through cylinder flat device carry out depth point comb, removal of impurities, needle cloth is provided on the cylinder of major diameter, using compared with
Short, shallower Bearded-needle knitted cloth, 65 ° of the operating angle of needle cloth can guarantee that the extended parallelization and Carding Degree of fiber, cylinder speed are suitable
When grasp is set to 425r/min, using somewhat higher cover plate speed, selection 235mm/min, the cotton through cylinder flat combing is fine
It ties up the doffer being subsequently rotated constantly to strip, doffing speed is directly related to the yield of carding machine, improves doffing speed and then produces
Amount increase, but speed it is excessively high can to point comb it is unfavorable, select doffing speed for 35r/min, doffer's electric machine frequency be 31Hz, by doffer
The cotton fiber stripped most obtains the cotton carded sliver at item, coiler mechanism through carding machine afterwards；
The cotton carded sliver made from the first step is realized that the cotton fiber in the carded sliver is further deep through full combing process by second step
Degree combing, thus by the short cotton fiber separation removing in the carded sliver and the fine impurities in the further removal carded sliver, so that cotton be made
Yarn, full combing process include preparatory process and combing process before combing, before combing preparatory process include pre-drawing process and
Item simultaneously rolls up process, and pre-drawing process uses the first drawing frame, and the first drawing frame is raw using 6 cottons withouyt evereven
Item is fed jointly, and draft mechanism adds guiding top roller curve drawing using 3/3 pressure bar, and draft mechanism includes rear roller, middle sieve
It draws, front roller, adds pressure bar at the rear portion of rear roller, add guide roller in the front of front roller, so that feeding
The 6 cotton carded slivers entered after pressure bar controls enter rear roller, then successively through between rear roller and middle roller first break draft area,
Control output through guide roller again after the drawing-off effect of the front draft zone draft area Liang Ge between middle roller and front roller, thus
Forming curves drawing-off effect, and the total draft multiple of draft area is set between 5.5-6.2, so that 6 cottons of feeding are raw
Item is stretched and attenuates through the drawing-off effect of the first drawing frame, then again and the first pre-drawing is synthesized, to be effectively improved cotton
The bar evenness of the carded sliver；24 first pre-drawings are fed into ribbon lap machine jointly then and are recycled, thus again
To combing cotton roll, to complete the preparation before combing, in ribbon lap machine, drafting system is led using 3/3 drawing-off Pneumatic Pressure
Stretched form, drafting system include rear roller, middle roller, front roller, the total draft multiple of drafting system between 1.3-1.5, from
And the straightening of fibers stretching action under small drawing-off is realized to 24 first pre-drawings of feeding, then again and synthesized combed cotton
Volume；Combing cotton roll is then fed into combing machine, is fed jointly using 8 combing cotton rolls, under draft mechanism uses five on three
Prass-bar draft, draft mechanism includes rear roller, middle roller, front roller, to lead after forming between rear roller and middle roller
It stretches and forms front draft zone between area, middle roller and front roller, first break draft area drafting multiple should performance according to raw material, combing cotton roll
In the requirement of fiber condition, output sliver adjust, when the straightening of fibers depth of parallelism of the combing cotton roll of feeding is preferable, after lead
The grasp bigger than normal of area's drafting multiple is stretched, when requiring the uniformity of combing sliver of output preferable, first break draft area drafting multiple is less than normal
It grasps, when material quality is poor, short fibre content is high, the grasp less than normal of first break draft area drafting multiple, conversely, then grasp bigger than normal, and
The total draft multiple of draft area is set between 115-130, so that the combing cotton roll of feeding is made through the high draft of combing machine
Strip structure is thinned down to being stretched again, under high draft effect, by combing to the depth under the free state of cotton fiber
Effect, so that wherein shorter cotton fiber is fallen removing, to generate cotton noils, during noil, while by one
A little more tiny impurity separate removing together；
Cotton ripe bar is made through mixing in doubling step together, to avoid strip in cotton yarn made from second step by third step
Excessively shredded to decline yarn quality, mixing in doubling step uses the second drawing frame, and the second drawing frame installs evereven, drafting additional
Process uses the technological principle of " tight gauge, again pressurization, light quantitative, jogging speed ", to improve the extended parallelization of fiber in strip
And the uniformity, it is fed jointly using 6 cotton yarns, draft mechanism adds guiding top roller curve drawing using 3/3 pressure bar, leads
Stretching mechanism includes rear roller, middle roller, front roller, adds pressure bar at the rear portion of rear roller, is installed additional in the front of front roller
There is guide roller, so that 6 cotton yarns of feeding enter rear roller after pressure bar controls, then successively through rear roller
It is passed through again after the drawing-off effect of the front draft zone draft area Liang Ge between first break draft area, middle roller and front roller between middle roller
The control of guide roller exports, so that forming curves drawing-off acts on, so that 6 cotton yarns of feeding are in first break draft area
Arranged and closed, carried out in front draft zone stretch attenuate, and be arranged draft area total draft multiple between 6.2-6.5,
Item in order to guarantee ripe bar is dry uniformly and the straightening of fibers depth of parallelism is good, by the setting less than normal of the drafting multiple in first break draft area, from
And realize and concentrate front draft zone drawing-off, thus improve the strip dry CV value of obtained cotton ripe bar, reduce weight unevenness, while after
The roller gauge of draft area needs slightly larger setting, and the roller gauge of front draft zone answers tight slightly setting, to reinforce pressure bar to front draft
The control of slow speed fiber in area makes speed change point move forward, thus realize that front draft zone extracts stretching action to the concentration of fiber, thus
So that 6 cotton yarns of feeding are organized first and are closed through the drawing-off effect of the second drawing frame, being then stretched attenuates, thus
It is effectively improved the weight unevenness and bar evenness of obtained cotton yarn；
Cotton ripe bar made from third step is made quantitative smaller through Roving Frames and has the cotton of the smaller twist thick by the 4th step
Yarn, Roving Frames use ring ingot fly frame, and fly frame is fed using the technological principle of " light quantitative, pressurization again " using 1 cotton ripe bar
Enter, fly frame mainly includes draft mechanism and twisting mechanism, and draft mechanism uses four roller double short apron drawing-offs, draft mechanism packet
Include rear roller, middle rear roller, middle front roller, front roller, thus between rear roller and middle rear roller form first break draft area, in after
Front draft zone, first break draft Qu Weijian are formed between draft area, middle front roller and front roller in composition between roller and middle front roller
Single-roller drawing-off, middle draft area are main drawing area, be provided with by selling above and below in middle draft area, upper and lower apron, spring of top apron cradle, every
Apron control element away from block composition, to realize effective control of fiber during counter extensioin, front draft zone is Distribution Area, and
The drafting multiple of front draft zone is 1, and collector is provided in front draft zone, keeps fiber movement more steady reliable；First break draft
Area is simple roller draft, using weight pressing technology method, prevents from having skidded phenomenon in drawing-off, using lesser back area draft
Multiple, biggish first break draft are separated away from can effectively reinforce the control for fiber, so that holding when yarn enters intermediate draft
Close structure is conducive to keep good item dry, since fibre weight is larger in fly frame, has friction to generate " automatic control " between fiber and makees
With, therefore middle draft area gauge setting bigger than normal, to realize effective drawing-off under multifilament state, while proparea Distribution Area is held
Away from be slightly larger than or equal to cotton fiber quality length, thus realize the yarn after counter extensioin effective arrangement effect；Through drafting machine
It is thick that the cotton with certain strength is twisted under the twisting twist effect of twisting mechanism after the cotton yarn output that structure drawing-off obtains
Yarn, it is contemplated that the cotton fiber of selection is thinner, and quantifying for the cotton yarn of feeding is relatively light, is designed using twist factor bigger than normal, but cannot
It is too big, " harmful drafting " is prevented on spinning frame；
Cotton rove made from 4th step is made quantitative smaller and with the larger twist through spinning process and had by the 5th step
There is the cotton coil of smaller package capacity, spinning process is using the ring throstle for adding grid ring compact spinning device, using 1
The feeding of cotton rove, spinning frame mainly include draft mechanism and twisting mechanism, and draft mechanism is added using four roller length apron cradles
Drawing-off is pressed, draft mechanism includes rear roller, middle rear roller, middle front roller, front roller, thus between rear roller and middle rear roller
It is led before being formed between draft area, middle front roller and front roller in composition between composition first break draft area, middle rear roller and middle front roller
Area is stretched, wherein first break draft area and middle draft area are drawing-off Distribution Area, are mainly responsible for and complete solving to the cotton rove of feeding
Arrangement, straightening of fibers are twisted, is that item is created to the dominant draft of yarn in front draft zone to keep the yarn for feeding front draft zone close
Part, front draft zone are main drawing area, are mainly responsible for the cotton yarn completed to obtaining after the double arrangements in first break draft area and middle draft area
Stretching attenuate, to obtain line density and cotton yarn that cotton coil is consistent；The cotton rove of feeding is led after being first into
It stretches in area, under the action of the small drafting multiple in first break draft area, the cotton fiber in one side cotton rove is further stretched
It stretches, mutual sliding occurs between the cotton fiber in another aspect cotton rove, so that the line density of cotton rove reduces, and
During cotton fiber sliding, axial rotation, and the twist direction in the direction axially rotated and cotton rove occur for cotton fiber
On the contrary, to obtain the first cotton yarn, the first cotton yarn enters middle drawing-off to realize that the backtwisting arrangement to cotton rove acts on
In area, under the action of the small drafting multiple of middle draft area, on the one hand the cotton fiber in the first cotton yarn is further drawn
It stretches, mutual sliding on the other hand occurs between the cotton fiber in the first cotton yarn, so that the line of the first cotton yarn
Density reduces, and during cotton fiber sliding, axial rotation, and the direction axially rotated and the first cotton occur for cotton fiber
The remaining twist is contrary in yarn, to realize that the backtwisting arrangement to the first cotton yarn acts on, to obtain the second cotton palpus
Item, the cotton rove of feeding is after double arrangements of first break draft area and middle draft area effect, the obtained cotton fiber in the second cotton yarn
The effect of entwining with more consistent extended parallelization, and between fiber reduces, so that the fiber in the second cotton yarn
Keep close under more parastate, the second cotton yarn enters in front draft zone, the big drafting multiple in front draft zone
Under the action of, a wide range of mutual sliding occurs between the cotton fiber in the second cotton yarn, so that the line of the second cotton yarn
Density substantially reduces, and then obtains the third cotton yarn being consistent with the cotton coil line density spinned；It is led through draft mechanism
The cotton pipe with certain strength is twisted under the twisting twist effect of twisting mechanism after the third cotton yarn output stretched

On cotton packet in cotton fiber under the suction of negative pressure by crawl in proportion, when grabbing cotton, grab cotton head using double and grab cotton roller, together
When hired roughneck's blade be retracted rib 3mm, it is ensured that the cotton block grabbed every time is smaller, and it is caducous few broken to be conducive to impurity, further to open
Pine is laid a good foundation；The mixing cotton fiber grabbed in proportion is transmitted in heavy object separator by transfer pipeline, in weight point
From in device, it is provided with magnet arrangement and negative pressure device, so that the weight of ferrous metal mixed in cotton fiber etc. be inhaled by magnet
Draw and separate exclusion with cotton fiber, while to the biggish blocky impurity such as non-ferrous weight, using the hard impurities such as weight with
The difference in the path that the flexible materials such as fiber move in negative pressure gas flow, so that non-ferrous weight mixed in cotton fiber is miscellaneous
Matter separates exclusion with cotton fiber, thus finally by the biggish impurity in the cotton fiber grabbed by griping cotton machine in heavy object separator
It removes；The suction that the cotton fiber of pipeline output through heavy object separator then passes through condenser is fed into Single axial waste silk opener
In, cotton-slitting beater is provided in Single axial waste silk opener, the cotton fiber of feeding realizes free state under the action of cotton-slitting beater
Under strike effect, thus by cotton fiber mainly with big flock existing for biggish bulk form impact at lesser bulk
Lower flock existing for form, and since cotton fiber is to be hit shredding in a free state, it can be in the larger of cotton-slitting beater
Impact force under realize the flexibility of cotton fiber hit, to reduce damage to cotton fiber in the shots to cotton fiber
Effect carries out shredding, removal of impurities processing using the area Luo Za of roller frame, V-type elasticity brad hired roughneck, four groups of triangle dirt stick compositions；
The cotton fiber exported through Single axial waste silk opener is then fed into multi-mixer, and 3-5 are provided in multi-mixer
High hopper, under airflow function, cotton fiber is equably blown into each cotton storehouse, forms moment random mixing effect for the first time, respectively
Fiber in hopper is conveyed through 90 degree of turnings, and is converged again at point, since the cotton fiber in each hopper enters
The length in path experienced is different when point, to realize in the cotton fiber of mixture the between a variety of different cotton fibers
Secondary path difference immixture, while under the cutting crawl and the shredding counterattack of evener roller effect of brad curtain, form third time
Tumble mixed effect, while being provided in the equipped at outlet port of hopper and giving cotton roller, thus defeated sending cotton roller to rotate cotton fiber
The lesser blocky impurity in cotton fiber is further separated into removing during sending；The cotton fiber exported through multi-mixer
It is then fed into main de-burring machine, hopper is provided with before main de-burring machine, main de-burring machine is used to comb the method that generation beats, through opening
The small flock that cotton machine shredding acts on enters hopper after hired roughneck's shredding, passes through transferring roller, big combing roller, mote knife, support cotton
The collective effect of plate etc., realizes further careful shredding and the efficient impurity removal of small flock, defers to when use that " thin feeding is gently opened
The technological principle of pine, high transfer, removal of impurities height, few damage "；The cotton fiber exported through main de-burring machine is then sequentially fed into except micro-
In dirt machine and different fine separator, thus by the more tiny blocky impurity or flexible impurity point in cotton fiber in except micronic dust machine
From removing, other fibers mixed in cotton fiber are subjected to separation removing in different fine separator；Complete fine impurities and the opposite sex
The cotton fiber that fiber is removed is then fed into carding machine, hopper is provided on rear side of carding machine, cotton fiber is sent first
Enter into the hopper of carding machine, the negative pressure pressure of the hopper of carding machine is set as 60Pa, and cotton layer is maintained at the 39%- of hopper height
Between 41%, thus by the cotton fiber of feeding to be constantly fed into carding machine after quality and cotton in homogeneous thickness layer output,
Cotton is uniformly fed to carding machine to realize, cotton carding uses the principle of " big gauge, light quantitative, jogging speed ", to cotton in carding machine
Fiber carries out point comb of depth, removal of impurities through cylinder flat device, is provided with needle cloth on the cylinder of major diameter, use is shorter, compared with
Shallow Bearded-needle knitted cloth, 65 ° of the operating angle of needle cloth can guarantee that the extended parallelization and Carding Degree of fiber, cylinder speed are suitably slapped
Hold and be set to 425r/min, using somewhat higher cover plate speed, select 235mm/min, the cotton fiber through cylinder flat combing with
The doffer being rotated afterwards constantly strips, and doffing speed is directly related to the yield of carding machine, and improving doffing speed, then yield increases
Add, but speed it is excessively high can to point comb it is unfavorable, select doffing speed for 35r/min, doffer's electric machine frequency be 31Hz, stripped by doffer
Cotton fiber most obtain the cotton carded sliver at item, coiler mechanism through carding machine afterwards；
The cotton carded sliver made from the first step is realized that the further depth of cotton fiber in the carded sliver is combed through full combing process by second step
Reason, so that the short cotton fiber separation in the carded sliver be removed and further remove the fine impurities in the carded sliver, so that cotton combing be made
Item, full combing process include preparatory process and combing process before combing, before combing preparatory process include pre-drawing process and item simultaneously
Process is rolled up, pre-drawing process uses the first drawing frame, and the first drawing frame is total using 6 cotton carded slivers withouyt evereven
With feeding, draft mechanism adds guiding top roller curve drawing using 3/3 pressure bar, and draft mechanism includes rear roller, middle roller, preceding
Roller, adds pressure bar at the rear portion of rear roller, adds guide roller in the front of front roller, so that the 6 of feeding
The root cotton carded sliver enters rear roller after pressure bar controls, then successively through the first break draft area between rear roller and middle roller, middle sieve
The control output through guide roller again after acting on the drawing-off of the front draft zone draft area Liang Ge between front roller is drawn, to be formed
Curve drawing effect, and be arranged draft area total draft multiple between 5.5-6.2 so that feeding 6 cotton carded slivers warp
The drawing-off effect of first drawing frame is stretched and attenuates, and then again and the first pre-drawing is synthesized, to be effectively improved the cotton carded sliver
Bar evenness；24 first pre-drawings are fed into ribbon lap machine jointly then and are recycled, to obtain essence again
Cotton carding volume, to complete the preparation before combing, in ribbon lap machine, drafting system uses the drawing-off shape of 3/3 drawing-off Pneumatic Pressure
Formula, drafting system include rear roller, middle roller, front roller, and the total draft multiple of drafting system is between 1.3-1.5, thus right
24 first pre-drawings of feeding realize the straightening of fibers stretching action under small drawing-off, then again and are synthesized combing cotton roll；
Combing cotton roll is then fed into combing machine, is fed jointly using 8 combing cotton rolls, and draft mechanism uses five lower pressure on three
Stick drawing-off, draft mechanism include rear roller, middle roller, front roller, thus formed between rear roller and middle roller first break draft area,
Form front draft zone between middle roller and front roller, first break draft area drafting multiple should be according in the performance of raw material, combing cotton roll
The requirement of fiber condition, output sliver is adjusted, when the straightening of fibers depth of parallelism of the combing cotton roll of feeding is preferable, first break draft area
Drafting multiple grasp bigger than normal, when requiring the uniformity of combing sliver of output preferable, the grasp less than normal of first break draft area drafting multiple,
When material quality is poor, short fibre content is high, the grasp less than normal of first break draft area drafting multiple, conversely, then grasp bigger than normal, and setting is led
The total draft multiple in area is stretched between 115-130, so that high draft effect of the combing cotton roll of feeding through combing machine is again
It is stretched and thins down to strip structure, under high draft effect, by the depth combing effect under the free state of cotton fiber, from
And wherein shorter cotton fiber is fallen into removing, to generate cotton noils, during noil, while by some more refinements
Small impurity separates removing together；
Cotton ripe bar is made through mixing in doubling step together, to avoid strip excessively in cotton yarn made from second step by third step
Shredded to decline yarn quality, mixing in doubling step uses the second drawing frame, and the second drawing frame installs evereven, mixing in doubling step additional
Using the technological principle of " tight gauge, again pressurization, light quantitative, jogging speed ", to improve in strip the extended parallelization of fiber and
Evenness is fed jointly using 6 cotton yarns, and draft mechanism adds guiding top roller curve drawing, drafting machine using 3/3 pressure bar
Structure includes rear roller, middle roller, front roller, adds pressure bar at the rear portion of rear roller, adds and lead in the front of front roller
To roller, so that 6 cotton yarns of feeding enter rear roller after pressure bar controls, then successively through rear roller in
Again through being oriented to after the drawing-off effect of the front draft zone draft area Liang Ge between first break draft area, middle roller and front roller between roller
The control of roller exports, so that forming curves drawing-off acts on, so that 6 cotton yarns of feeding carry out in first break draft area
Arrange and close, carried out in front draft zone stretch attenuate, and be arranged draft area total draft multiple between 6.2-6.5, in order to
Guarantee that the dry uniform and straightening of fibers depth of parallelism of the item of ripe bar is good, by the setting less than normal of the drafting multiple in first break draft area, thus real
Front draft zone drawing-off is now concentrated, to improve the strip dry CV value of obtained cotton ripe bar, reduce weight unevenness, while first break draft
The roller gauge in area needs slightly larger setting, and the roller gauge of front draft zone answers tight slightly setting, to reinforce pressure bar in front draft zone
The control of slow speed fiber makes speed change point move forward, thus realize that front draft zone extracts stretching action to the concentration of fiber, so that
6 cotton yarns of feeding are organized first and are closed through the drawing-off effect of the second drawing frame, being then stretched attenuates, thus effectively
Improve the weight unevenness and bar evenness of obtained cotton yarn；
Cotton rove quantitative smaller and with the smaller twist is made through Roving Frames in cotton ripe bar made from third step by the 4th step,
Roving Frames use ring ingot fly frame, and fly frame is fed using the technological principle of " light quantitative, pressurization again " using 1 cotton ripe bar,
Fly frame mainly includes draft mechanism and twisting mechanism, and draft mechanism uses four roller double short apron drawing-offs, and draft mechanism includes
Rear roller, middle rear roller, middle front roller, front roller, thus between rear roller and middle rear roller form first break draft area, in after sieve
It draws and forms front draft zone between draft area, middle front roller and front roller in composition between middle front roller, first break draft area is simple
Roller draft, middle draft area are main drawing area, are provided with by selling above and below in middle draft area, upper and lower apron, spring of top apron cradle, gauge
The apron control element of block composition, to realize effective control of fiber during counter extensioin, front draft zone is Distribution Area, and preceding
The drafting multiple of draft area is 1, and collector is provided in front draft zone, keeps fiber movement more steady reliable；First break draft area
It prevents from having skidded phenomenon in drawing-off using weight pressing technology method for simple roller draft, using lesser back area draft times
Several, biggish first break draft is separated away from can effectively reinforce the control for fiber, so that keeping knot when yarn enters intermediate draft
Structure is close, is conducive to keep good item dry, since fibre weight is larger in fly frame, has friction to generate " automatic control " between fiber and makees
With, therefore middle draft area gauge setting bigger than normal, to realize effective drawing-off under multifilament state, while proparea Distribution Area is held
Away from be slightly larger than or equal to cotton fiber quality length, thus realize the yarn after counter extensioin effective arrangement effect；Through drafting machine
It is thick that the cotton with certain strength is twisted under the twisting twist effect of twisting mechanism after the cotton yarn output that structure drawing-off obtains
Yarn, it is contemplated that the cotton fiber of selection is thinner, and quantifying for the cotton yarn of feeding is relatively light, is designed using twist factor bigger than normal, but cannot
It is too big, " harmful drafting " is prevented on spinning frame；
5th step, by cotton rove made from the 4th step through spinning process be made it is quantitative smaller and with the larger twist and with compared with
The cotton coil of small package capacity, spinning process are thick using 1 cotton using the ring throstle for adding grid ring compact spinning device
Yarn feeding, spinning frame mainly include draft mechanism and twisting mechanism, and draft mechanism is led using the pressurization of four roller length apron cradles
It stretches, draft mechanism includes rear roller, middle rear roller, middle front roller, front roller, to form between rear roller and middle rear roller
Front draft zone is formed between draft area, middle front roller and front roller in composition between first break draft area, middle rear roller and middle front roller,
Wherein first break draft area and middle draft area are drawing-off Distribution Area, and it is whole to the carry out backtwisting of the cotton rove of feeding to be mainly responsible for completion
Reason, straightening of fibers create conditions to the dominant draft of yarn for front draft zone to keep the yarn for feeding front draft zone close, preceding
Draft area is main drawing area, is mainly responsible for the stretching completed to the cotton yarn obtained after the double arrangements in first break draft area and middle draft area
Attenuate, to obtain the cotton yarn that line density and cotton coil are consistent；The cotton rove of feeding is first into first break draft area,
Under the action of the small drafting multiple in first break draft area, the cotton fiber in one side cotton rove, which is further stretched, to be stretched, separately
Mutual sliding occurs between cotton fiber in one side cotton rove, so that the line density of cotton rove reduces, and in cotton fibre
During dimension sliding, axial rotation occurs for cotton fiber, and the direction axially rotated is contrary with the twist of cotton rove, from
And realize that the backtwisting arrangement to cotton rove acts on, to obtain the first cotton yarn, the first cotton yarn is entered in middle draft area,
Under the action of the small drafting multiple of middle draft area, on the one hand the cotton fiber in the first cotton yarn, which is further stretched, is stretched,
On the other hand mutual sliding occurs between the cotton fiber in the first cotton yarn, so that the line density of the first cotton yarn subtracts
It is small, and during cotton fiber sliding, axial rotation occurs for cotton fiber, and in the direction axially rotated and the first cotton yarn
The remaining twist is contrary, to realize that the backtwisting arrangement to the first cotton yarn acts on, to obtain the second cotton yarn, feeds
Cotton rove after double arrangements of first break draft area and middle draft area effect, the obtained cotton fiber in the second cotton yarn has more
Consistent extended parallelization, and the effect of entwining between fiber reduces, so that the fiber in the second cotton yarn is kept more
Close under parastate, the second cotton yarn enters in front draft zone, under the action of the big drafting multiple of front draft zone,
A wide range of mutual sliding occurs between cotton fiber in second cotton yarn, so that the line density of the second cotton yarn substantially subtracts
It is small, then obtain the third cotton yarn being consistent with the cotton coil line density spinned；Obtained through draft mechanism drawing-off
The cotton coil with certain strength is twisted under the twisting twist effect of twisting mechanism after the output of three cotton yarns；
The cotton cylinder yarn with larger package capacity is made through winding procedure, to increase in cotton coil made from 5th step by the 6th step
The capacity for adding yarn package is readily transported and stores, and improves the production efficiency of later process；Yarn defect is removed simultaneously, checks yarn
Diameter removes fault and impurity on yarn, improves yarn quality.
