Latitude is firmly spent, the quality of fabric is influenced, when producing cutting motif fabric, needs to prevent in one layer of frivolous clad of seta roller surface packet
Only licker-in roller hook yarn, clad cannot be thick, coat thickness, will affect licker-in roller to the control ability of cloth cover, to influence fabric
Quality;
Opening time: opening time is determined as 290 °;
Weft yarn beginning flying angle: the upper machine reed width of this fabric is smaller, only 162cm, therefore, when weft yarn has enough flight
Between, later weft yarn beginning flying angle need to be used, the beginning flying angle for selecting weft yarn is 95 °;
Weft yarn angle of arrival: this fabric weft yarn angle of arrival is determined as 230 °;
The pneumatic picking time: GA718 type air-jet loom is configured with 8 groups of pilot jets, when this fabric produces, due to upper machine
Reed width is smaller, therefore actually uses 7 groups of pilot jets, auxiliary spray every group 4, and the maximum spacing of auxiliary spray is 6.5cm;Loom revolving speed is
520m/min, the angle that loom 1ms is turned over are 3.12 degree, and the reaction time of solenoid valve is 5ms, and sluggish angle is 16 °, and weft yarn begins to fly
Row angle is 95 °, and weft yarn angle of arrival is 230 °, whole 250 ° of the spray angle of auxiliary spray, pneumatic picking technological parameter are as follows: gear yarn needle release angle=
Weft yarn beginning flying angle-sluggishness angle=79 °, when the first latitude is weaved, since loom does not reach normal revolving speed, weft yarn has enough
Flight time, gear yarn needle release time can be 10 ° late, and it is 89 ° that the first latitude, which keeps off yarn needle release angle,;Main jet jet time be 69 °-
170 °, when the first latitude is weaved, main jet jet angle is 79 ° -170 °, identical when reason is with gear the first latitude of yarn needle weaving;First group
Pilot jet jet angle is 69 ° -130 °, and second group of pilot jet jet angle is 90 ° -150 °, the spray of third group pilot jet
Air horn degree is 110 ° -170 °, and the 4th group of pilot jet jet angle is 130 ° -190 °, and the 5th group of pilot jet jet angle is
150 ° -210 °, the 6th group of pilot jet jet angle is 170 ° -230 °, the 7th group of pilot jet jet angle be 190 ° -
290 °, the 7th group of pilot jet jet end time, should be identical as the whole spray angle of auxiliary spray, but since GA718 type jet is knitted
Machine does not have draw jet, and to prevent looped weft, last group of pilot jet end time is deferred to 290 ° of heald level time;
Whiff pressure: main jet pressure is set as 0.22MPa, and the auxiliary power of spraying is set as 0.26mpa, machine reed width on this fabric
There is 162cm, upper machine reed width is small, and weft yarn flying speed does not need very fastly, thus lesser whiff pressure can be selected;Production process
In, weft yarn angle of arrival is set as 230 °, from loom display screen, checks that weft yarn is actually reached angle, practical weft yarn angle of arrival control
Between 220 ° -230 °, whiff pressure is no longer needed for adjusting, if being actually reached angle earlier than 220 °, can suitably turn jet down
Pressure needs to increase whiff pressure if being actually reached angle is later than 230 °, prevents that short latitude stops platform;
Gentle breeze: when this fabric produces, since weft yarn is thinner, weft yarn screen resilience is small, and gentle breeze pressure is controlled in 0.06-
Between 0.08mpa, 0.08mpa is not exceeded, gentle breeze pressure is big, and Weft Detwisting is fast, and weft yarn is easy to be blown;
Back beam height: GA718 type air-jet loom, configuration is type dobby shedding mechanism, and common back beam height is 0 scale,
When this fabric weaves, thread count is all bigger, and weft yarn is not easy urgent, and fell backwash is big, therefore back beam height is increased to 1
The tension difference of scale, layer warp thread upper and lower in this way is big, and weft yarn is easy urgent;
Warp tension: warp count is big, and shed open is not easy clearly, it should use biggish warp tension, but this fabric warp
Relatively thin, single thread force is low, and after overall balance, tension is set as 130kg.
As optimization: the Fabric width of the fabric is 146cm, finished product through it is close be 559/10cm, broadwise have ground weft and
Flower latitude, one spends middle ground weft width 2.5cm, 92 yarns of ground weft, and density is 368/10cm at ground weft, and one spends middle colored latitude width
0.2cm, flower latitude 12, flower weft density is 600/10cm, and every colored fill yarn ends are 104 latitudes, average filling density=104/2.7 × 10
=385/10cm, warp yarn shrinkage 9.0%, weft shrinkage 3.7%, dyeing and finishing width shrinkage 6.5%, the long shrinkage of dyeing and finishing is 1.0%.
The utility model has the advantages that, due to being limited through cutting motif fabric by every reed penetration number and reed, flower pattern can not show a candle in the present invention
Latitude cutting motif fabric is abundant.Latitude cutting motif fabric floats the front that long line floats on fabric by latitude, decorative pattern is formed, due to GA718 type loom
Electronic take-up mechanism has been used, 8 kinds of filling densities at most can be used in same kind, so that the patterning design of latitude cutting motif fabric becomes non-
It is often convenient, it can be also far below according to the arbitrarily devised filling density of requirement of flower pattern, difficulty of weaving through cutting motif fabric, product quality is better than
Through cutting motif fabric.
When producing latitude cutting motif fabric, it should be noted that the following: the basic organization of 1. latitude cutting motif fabrics, it is preferred to use plain weave group

3.5 weavings:
GA718 type air-jet loom is selected to weave.GA718 type air-jet loom, by Shanghai Textile Machinery, factory is produced, configured with electricity
Sub- type dobby shedding mechanism, the heald frames of page 16, loom speed 520r/min.
Become filling density weaving:
The loom of non-electronic spooler, which can also weave, becomes filling density fabric, and when weaving ground weft, spooler is normally batched,
Hua Weishi is woven, by dobby wirerope, hook will be batched and lifted, stop batching.In actual production process, hook quilt is batched
After lifting, fell can be moved back, and practical filling density is difficult to control, and the quality of fabric is difficult to ensure, can only weave some low grade products.
It is configured with electronic take-up and electronic warp feeding in GA718 type air-jet loom, in technique setting menu, chooses to batch and send
Through system, filling density is set.8 kinds of filling densities can be at most designed in system as needed, 2 kinds of filling densities are arranged in this fabric, and filling density 1 is set as
364/10cm, filling density 2 is set as 594/10cm, and chooses and become filling density weaving, then in technological design menu, chooses figure

The use of structure, so that the size of filling density can be controlled arbitrarily as needed, the quality of fabric can be effectively guaranteed.
Licker-in roller: when weaving broadwise cutting motif fabric, due to flower latitude to float long line longer, it is easy to by the acicular hook on licker-in roller
Firmly flower warp or flower latitude, influence the quality of fabric, when producing cutting motif fabric, need in one layer of frivolous cladding of seta roller surface packet
Layer prevents licker-in roller hook yarn, and clad cannot be thick, coats thickness, will affect licker-in roller to the control ability of cloth cover, to influence
The quality of fabric.
Opening time:
Opening time is determined as 290 degree.The common opening time of type air-jet loom is 290 ° -320 °, this fabric weaves
When, warp thread radical is more, and shed open is not easy clearly, using early opening, is conducive to that shed open is clear, and opening time is determined as 290 °.It adopts
With early opening, there are one the reason is that: fabric tissue is plain weave, yarns interwoven often, weft yarn be not easy it is urgent, using early opening
Be conducive to urgent weft yarn.
Weft yarn beginning flying angle:
GA718 type air-jet loom, for common weft yarn beginning flying angle between 80 ° -90 °, this fabric determines that weft yarn begins to fly
Angle is 95 °.The determination of weft yarn beginning flight angle mainly determines that upper machine reed width is wide according to machine reed width on fabric, to guarantee latitude
Yarn has enough flight time, and often using weft yarn beginning flying angle earlier, but weft yarn beginning flying angle is early, shed open effective height
It is small, in weft yarn flight course, filoplume on warp thread may be encountered or Warp opening is unintelligible, weft yarn directly encounters warp thread,
Short latitude is caused to stop platform.When this fabric produces, the upper machine reed width of fabric is smaller, only 162cm, and therefore, weft yarn has enough fly
The row time can use later weft yarn beginning flying angle, and the beginning flying angle for selecting weft yarn is 95 °.Weft yarn beginning flying angle is also not easy again
Evening, flying angle evening weft yarn beginning, weft yarn will also reach opposite side shed open in defined angle, this just needs biggish whiff pressure, spray
Atmospheric pressure is big, and can cause long irregular pick point, while also adding the consumption of gas consumption.
Weft yarn angle of arrival:
The type loom, common weft yarn angle of arrival are 220 ° -230 °, and broad fabric weft yarn angle of arrival can control the latest
240°.Weft yarn reaches evening, and when weft yarn goes out shed open, shed open effective height is small, is easy at the selvedge of right side when weaving, and forms side looped weft
Fault influences the quality of fabric.This fabric weft yarn angle of arrival is determined as 230 °, and weft yarn angle of arrival should not be early, because weft yarn reaches
Angle is early, and whiff pressure needs are larger, and pressure is big, and one side compressed air consumption is big, on the other hand be easy to cause long irregular pick point.
The pneumatic picking time:
GA718 type air-jet loom is configured with 8 groups of pilot jets, when this fabric produces, since upper machine reed width is smaller,
7 groups of pilot jets are actually used, are able to satisfy the production requirement of fabric completely.Auxiliary spray every group 4, the maximum spacing of auxiliary spray is 6.5cm.
Loom revolving speed is 520m/min, and the angle that loom 1ms is turned over is 3.12 degree, and the reaction time of solenoid valve is 5ms, and sluggish angle is
16 °, weft yarn beginning flying angle is 95 °, and weft yarn angle of arrival is 230 °, whole 250 ° of the spray angle of auxiliary spray, pneumatic picking technological parameter are as follows: gear yarn
Needle release angle=weft yarn beginning flying angle-sluggishness angle=79 °, when the first latitude is weaved, since loom does not reach normal revolving speed,
Weft yarn has enough flight time, and gear yarn needle release time can be 10 ° late, and it is 89 ° that the first latitude, which keeps off yarn needle release angle,;Main jet spray
The gas time is 69 ° -170 °, and when the first latitude is weaved, main jet jet angle is 79 ° -170 °, when reason is with gear the first latitude of yarn needle weaving
It is identical;First group of pilot jet jet angle is 69 ° -130 °, and second group of pilot jet jet angle is 90 ° -150 °, third group
Pilot jet jet angle is 110 ° -170 °, and the 4th group of pilot jet jet angle is 130 ° -190 °, the 5th group of pilot jet
Jet angle is 150 ° -210 °, and the 6th group of pilot jet jet angle is 170 ° -230 °, the 7th group of pilot jet jet angle
It is 190 ° -290 °, the 7th group of pilot jet jet end time, should be identical as the whole spray angle of auxiliary spray, but due to GA718 type
Air-jet loom does not have draw jet, and to prevent looped weft, last group of pilot jet end time is deferred to 290 ° of heald level time.
Whiff pressure: main jet pressure is set as 0.22mpa, and the auxiliary power of spraying is set as 0.26mpa.Machine reed width on this fabric
There is 162cm, upper machine reed width is small, and weft yarn flying speed does not need very fastly, thus lesser whiff pressure can be selected.Weft yarn compares
Carefully, whiff pressure should not be big, and pressure is big, is easy to produce long irregular pick point.In production process, weft yarn angle of arrival is set as 230 °, from
In loom display screen, check that weft yarn is actually reached angle, practical weft yarn angle of arrival control is between 220 ° -230 °, and whiff pressure is just
It no longer needs to adjust, if being actually reached angle earlier than 220 °, can suitably turn whiff pressure down, be later than if being actually reached angle
It 230 °, needs to increase whiff pressure, prevents that short latitude stops platform.Using lesser whiff pressure, gas consumption on the one hand can be reduced
Consumption, on the other hand can be reduced long irregular pick point.
Gentle breeze: common gentle breeze pressure is 0.08mpa, and when this fabric produces, since weft yarn is thinner, weft yarn screen resilience is small,
Gentle breeze pressure controls between 0.06-0.08mpa, does not exceed 0.08mpa, and gentle breeze pressure is big, and Weft Detwisting is fast, and weft yarn is easy
It is blown.
Back beam height: GA718 type air-jet loom, configuration is type dobby shedding mechanism, and common back beam height is 0 scale,
When this fabric weaves, thread count is all bigger, and weft yarn is not easy urgent, and fell backwash is big, therefore we mention back beam height
For height to 1 scale, the tension difference of layer warp thread upper and lower in this way is big, and weft yarn is easy urgent.
Warp tension: warp count is big, and shed open is not easy clearly, it should use biggish warp tension, but this fabric warp
Relatively thin, single thread force is low, and after overall balance, tension is set as 130kg.
4. the trimmed size of fabric:
Fabric width is 146cm, finished product through it is close be 559/10cm, broadwise has ground weft and flower latitude, and one spends middle ground weft width
2.5cm, 92 yarns of ground weft, density is 368/10cm at ground weft, and one spends middle colored latitude width 0.2cm, flower latitude 12, flower weft density
For 600/10cm, every colored fill yarn ends are 104 latitudes, average filling density=104/2.7 × 10=385 root/10cm, warp yarn shrinkage
9.0%, weft shrinkage 3.7%, dyeing and finishing width shrinkage 6.5%, the long shrinkage of dyeing and finishing is 1.0%.
Conclusion:
It is limited through cutting motif fabric by every reed penetration number and reed, it is abundant that flower pattern can not show a candle to latitude cutting motif fabric.Latitude clipping and carving
Fabric floats the front that long line floats on fabric by latitude, forms decorative pattern, since GA718 type loom has used electronic take-up mechanism, together
8 kinds of filling densities at most can be used in one kind, so that the patterning design of latitude cutting motif fabric becomes very convenient, it can be according to flower pattern
It is required that arbitrarily devised filling density, difficulty of weaving is also far below through cutting motif fabric, and product quality is better than through cutting motif fabric.Produce latitude clipping and carving
When fabric, it should be noted that the following: the basic organization of 1. latitude cutting motif fabrics, it is preferred to use plain weave;2. yarn count is thin;3. knitting
The thread count of object is big.As long as meeting above, the fabric woven out at 3 points, close fine and smooth, flower pattern is small and exquisite changeable, and perception is good,
It is chiefly used in weaving summer shirt fabric.
The present invention is not limited to above-mentioned preferred forms, anyone can show that other are various under the inspiration of the present invention
The product of form, however, make any variation in its shape or structure, it is all that there is skill identical or similar to the present application
Art scheme, is within the scope of the present invention.
