One.
1 mechanical part is not accurate, because the equipment accuracy is not high, or mechanical
Aging equipment, syringes single pernicious peace of synchronous data beyond the permitted
Range, it will be business as usual sense of the yarn tension variations and fluctuations, the last guide
Induced coil, the size of such produce Dahenglu Dahenglu general mechanical adjustment number
It will disappear after,
2, the yarn output tray and the transmission line problems in some more and then called fly except
Poor dust system manufacturers, not a long time to clean up the output tray slider yarn product
The words have been flying since the slider aging rubber sleeve, so that the belt answer, speed
Degree abnormal, yarn sending speed produce Dahenglu, lost the plot yarn fly,
Anti fail to do so up and down in the drive position, a boot As the yarn is negative
State, arising Dahenglu,
3 debug problems in the debugger when the depth of the upper and lower pressure needle triangle
Mixed nephew, resulting cloth coil has size, produce Dahenglu, such problems
In general, the law, because the triangular indenter depth than with the naked eye to see
More difficult, so we put in the time to debug the machine under the pressure of the needle bar
To a pressure needle depth position, and then transferred the pressure needle, then with yarn
Tension as standard, in this process, we often encounter such a
See the phenomenon that rib fabrics, warp in the fabric surface two straight lines perpendicular to
The line will be a while intermediate ring size while small alley, causes
The pressure needle is not pressed together, this phenomenon also has cotton wool, fabric will be very
Ugly, the other because of the upper and lower triangular seat sharing would not lead to this phenomenon
Occurrence, the concept is in line with these points on the circumference of the upper and lower ranges
Points, so that inconsistency into cloth upper and lower pressure when the needle point of the needle, this issue
It is difficult to see to the naked eye
4, the raw material problem, the more common problem of raw materials, produced in the form of Wang Road
Yellow IOUs Henglu. Irregular Batocera Dahenglu such Dahenglu generally change
After the yarn can be solved, but some are hidden Dahenglu such Dahenglu most hemp
Trouble, yarn quality is poor, uneven twist, yarn mix will yield
Students such problems, one of stripes spandex fabric is a common problem, there are
Some more spandex problem of poor quality. Such as sticky twist resistance is too large, fluffy
Sex.
5, color issues, sometimes we encounter such a situation, that is,
On Mao no Dahenglu blank, but the light came out full of blank Wang Road. Then weave
He said the issue will be made dyeing, bleaching will say weaving problems. I have
After hearing a friend so and I said: This is due to the raw absorption color
Dahenglu color caused by poor, light-colored dye or bleach all right, it seems
Some truth, but whether that is the case specifically, I am unable to verify, off
Here on this topic, please tell a friend dyeing.
6, creel yarn guide structure issues, such problems in terry machine, especially in the open
Chemical fiber F generated when the number is higher, typically being configured nap or taut yarn guide
Dahenglu generated such Dahenglu obvious, so some manufacturers setter
Creel will be between landing or lose with the feel of the yarn tension to check.
7, stop Dahenglu the problem, generally with the broader market as the main drive gear teeth
Wheel gap and the gap with the broader market base and gear problems, cloth open
Thicker, down across the clear, most do debugging for such Dahenglu
Mitigation, all finished to eliminate unlikely, because it has been characterized at the factory.

Knitting yarn bar problem solving techniques and management for cross-knitting yarn
Article probability produced will be greatly reduced, no matter what the circumstances knitting yarn
Bar next generation, we will give knitting yarn, knitted fabrics manufacturers bring
Great economic losses, whether knitting yarn knitted in a later step
Generate bar dyeing process we will know only after staining. Knitting
Bar was the emergence of the problem there is cotton, but also knitting, dyeing and finishing plant
The problem, for knitted stripes distinguish the type generally follow through
Inspection laws: ① cotton regularity and apparent bar shadows, a
Generally by certain yarn twist unevenness,
Wrong number, weight deviation is too large, single or multiple mixed batch of cotton produced;
② Knitters produce a regular bar, generally due to the knitting machine
Some tension unevenness or knitting needle use cotton mixed batch, wrong number,
Caused by wrong batch; knit stripes ③ dyeing factory produced general performance
Lighter stripe or bar without any rules, cause this bar of
The main reason is knitted in a vat scouring for too long, or knitting
Cloth in the dye vat dye can not penetrate so wrinkled, dye concentration interlayer difference
Too big, there is staining caused by poor water quality will appear dyed knitted fabric
④ reason caused by irregular stripes; color bar
Are: mixed cotton uneven, irregular use of raw cotton to replace cotton into
Maturity differences, sliver mixing uneven, thick cotton long long more details,
Dyeing pressure is not enough, uneven staining liquid concentration, dyeing temperature steam
Enough, vat not clean, cotton cloth in the dye vat scouring too long;
Reason ⑤ regularity bar produced: there are also reasons for both cotton needle
Factors weaving factory, because cotton has twist unevenness, wrong wrong support grant,
Cotton mixed uneven, uneven batch pick cotton; reason Knitters are not tension
Uniform, wrong wrong branch approval.
Technical measures to solve knitting yarn bar include: stable mixed cotton
Quality, the best mixed batch of cotton once a turn; stable than cotton successor
Examples and time; reduce spindle twist difference between the control carding strip,
Combing, and uneven roads of weight and weight deviation and prevent cotton mix
Support mixed batch, to prevent long thick and long sections detail generation. Including scanning facilities management
: Development of mixed cotton quality control standards and implement row packet inspection, no-
Defects spinning perform operations management, strengthen maintenance equipment maintenance management,
Strict blocking spinners produce the wrong batch dead wrong branch link (wrong tube, mixing tube, wrong
