Soft winding New Technology:

New Soft winding technology advantage and theory description

Perfect yarn winding and dyeing are connected closely, application and research are in synchronous developing in these field. It is very deep affection to next dyeing process by package quality.  

Yarn density uniformity of the dye can penetrate layer by layer yarn, in a dyeing batches ensure consistent flow.

Sunking soft winding machine features:

So far, for spun yarn is cannot use production of grooved drum winder for greater than the density of the staining of 0.38 g / cubic centimeter of yarn, the reason is grooved drum winding technology leads to the yarn and yarn winding density overlap are not hindered the dye penetration.

Sunking new groove drum winding machine, winding speed maximum reach the production speed of 1600 M / min, the digital tension control system and advanced anti overlapping technique can in the cross angle of 14 degrees, the working speed of can in higher than 1000 meters / minute, the yarn density can do more than 0.45 grams / cubic centimeter of uniform density and the density along axial direction and the radial density identical yarn while at the same time ensure perfect dyeing quality. This means that let the quantity of yarn improve / in the same volume we wound more yarn, dyeing cost without any increase.

The simple yarn design completely eliminates the yarn on the road due to wear the yarn path folding angle of yarn damage, eliminate the can affect the yarn hairiness and strength of many problems.

Winding kinds:

The use of drum winder technology, the advantages of fiber winding.

In the whole winding process, the intersection angle is constant, which is simple, practical and the most economical winding way.

The groove barrel type winding machine is a grooved drum winding with the following characteristics:

- The yarn is constant in the channel

- Constant winding angle

- The angular velocity of yarn decreases with the yarn diameter;

- The number of winding yarn is proportional to the diameter of tube.

Precision winding machine barrel of the drum type winding machine is different, its character is guided around the hook yarn traverse, the rhythm with yarn rotation frequency, yarn is allocated to the surface of the bobbin.

Its advantage is the long fiber, but its obvious defect is, intersection angle decreased when the yarn diameter increases, the result is yarn in yarn distribution inhomogeneity. So the edge of the yarn is distributed more yarn, so the density of the edge is more, because of the decrease of the angle. In the initial stage, the cross angle is larger, the yarn winding stability on the bobbin is not good. And guide yarn hook to reduce the speed in the direction of rotation is close to the end, because the yarn speed did not change, which led directly to the in the region distribution more yarn, leading to the hard edge of the cone yarn, the attendant problems is stained unevenness of yarn edge is easy to fall off and stability decreased, and pineapple tube winding used in order to avoid such problems, is a direct result of lower the capacity of yarn.

Perfect Anti-ribbon:

Futerritory pro*According to the principle of random winding in the slot, the characteristics of the region overlap with the diameter ratio factor are the characteristics of the region overlap. With axial traverse device used, the yarn in winding of axial reciprocating displacement, the yarn end surfaces on both sides of the yarn to form a soft edge without overlapping, in order to be the same axial density. Yarn of brachial pressure regulation by the reverse of the cylinder and in the winding the yarn diameter gradually increases, gas spring reverse should be force to offset the yarn to gradually increase the weight, in order to maintain the pressure arm of the same, to ensure yarn radial density consistent.

"Perfect anti overlapping" system to production for in the dying completely uniform high density yarn, and yarn diameter unchanged, the dyeing machine production capacity has been significantly improved.

Overfeeding system:

Overfeeding device adopts modular discrete design, simple threading path. The high sensitivity of the tension sensor detection range of up to 0.1g, can be carried out in the whole winding process in real-time monitoring and feedback to the processing unit, the central processing unit is actively responding / driving device to fully control the yarn tension and display the tension state. The initial winding end of the yarn is used for the initial tension device of the self cleaning, to prevent the tension fluctuation caused by the Mao Yu residue. Regardless of how changes in the winding winding speed even yarn in faded around when, random changes in natural tension due to bond and other factors caused by the tension of the moment, and feed yarn diameter becomes small case, winding tension remained in the setting of a constant value. At the same time, with high anti overlap to avoid any yarn winding overlap together, which can avoid overlapping area within the yarn local density increases, and the impact of a uniform distribution of dye.

The optimization and upgrading of the chromium layer metal overfeed wheels; the yarn is widely used, high hardness solves the drawbacks from the early of carbon fiber coating material easy to wear and tear of the, is suitable for winding for a long time.

The loose type coning is a very special skills of production process, perfect yarn winding to make dye in the dyeing process can be uniformly distributed. In order to get the yarn density uniform, the yarn tension control is extremely important.

To avoid this kind of problem, the model of the system is equipped with a digital constant tension feeding device.

Actual production test report

Dyeing test with 40 British branch cotton yarn, moderately deep color (camel Beige), 54 packages.

Traditional industrialization of dyeing factory of cotton dyed using density is generally 0.33-0.35 grams / cubic centimeter, each yarn weight at 900 - 1000 grams.
The cylinder yarn density of 0.45 g / cubic centimeter, and the data obtained by the model are clearly stated. The traditional winding machine can directly increase the dyeing output by 36.5%, and the production cost is not increased.

Data obtained by the actual dyeing tests: 1000 l / vertical dyeing machine

Through the actual dyeing test, the diameter of the yarn is not constant, but the density of the cylinder is improved, and the economy of the production process of the capacity of the tube yarn is greatly improved, especially the following items:

-Product logistics
- Storage
- Packing
-Production process (dyeing, dehydration, dryer)
- Labour cost
1. time
2. electricity consumption
3. water consumption
4. dyestuff and chemical
   
Output ratio: for 40 single yarn and other winding machine, the efficiency of 85%

From the test data, the production efficiency of the high efficiency of the cylinder is higher than that of the 47%, which is higher than the 129% of the traditional 1332 type trough tube winding machine. It can directly reduce the workload in the process of winding / including operators and porters and volume of employment.

Dyeing process, in the same configuration dyeing production requirements can be significantly optimized to enhance the efficiency in the use of VAT / maximum improve capacity utilization, particularly critical is: refining and dyeing process does not need to make any adjustments, every process to complete the time there is no any change, circulation pump speed is not any change. For the production process of logistics, warehousing, packaging, etc., than the traditional tube yarn density and the same weight, the need for working hours as well as storage and logistics have been saved.

 Therefore, the increase in the density of any cylinder can be reduced in proportion to the time of production, consumption and cost.
