Technical characteristics

Knitting function:

It is able to knit the basic knitting organizations (full needle,single side etc), multicolour random jacquard weave, applique(intarsia), twist knitting, pointelle and other weft knitting organizations. It is applicable for real silk, spun silk, synthetic, wool, acrylic, blended, yarn and other raw materials toknit the sweater and scarf, cap, trousers,socks and garment accessories. The function of wholegarment knitting and filling knitting is possible.

Product Specifications:

Knitting system single head double system,single head three system
Gauge 9G12G, 14G
Knitting range 22,36,52Inch
Knitting speed It adopts 128 segments with the maximum speed of 1.5m/s. AC servo motor control is adopted and controlled by refined feedback control and DSP with high-speed computation capability, for the purpose of controlling the IGBT to generate precise current output.
Needle bed shifting AC servo motor control is adopted with the needle shifting range realizing 2 inches; in the meantime, it is of precise fine tuning functions.
Yarn feed device Positive yarn feeder and guide wheel with standard configuration has greatly reduced the resistance of yarn feeding.
Power single phase 220V/three phase 380V; it adopts the advanced CMOS technology to memorize and recover at the moment of power cut.


1.D3 type first use the 5.0inch compound needle-bed  rail carriage, each carriage system width narrow by 30mm, to match the 0.05ms high speed return of carriage servo ( such as: for three system machine running with 90 speed, 10 lines save 1 second.)  It is a leap on the basis of A2 type machine;

2. The integrated installation of sinker and cam plate of carriage, it ensure the consistency and stability between sinker device and whole carriage, and it is easier for operator to observe the looping process;

3. Add adjustable tight knitting and tight tuck function、expand the knitwear design varieties;

4. In the carriage, heavy use the intelligent encoder on the basis of motorized. It can find the zero position intelligently and feedback the position information  circularly (it mean when send a command,it will go to finish the command and feedback the result ). It improved the qualification rate of knitwear greatly, customers and maintance staff can use it conveniently;

5. Double layer separate stitch cam design, it has finish the single needle stitch effect. For stitch control, it use the customized motor to accurate it to 0.005mm, it greatly improve the flatness of knitwear ;

6.The raising cam is controlled seperately, can do pre-select in the middle when single system working. The carriage can turn back from the middle when automatic locking, it greatly improved the working efficiency as it saved unnecessary working distance;

7. It can with 2*8 groups of yarn mouth configurations are equipped in two sides of four guide rails for the purpose of shifting the yarn mouth at any position of needle bed( sweater machine's standard configuration 1*8, shoe machine's standard configulation 2*8) ;It also can equipped with automatic feeder device.

8.The high-quanlity batching roller system, the soft upper roller traction which is specially designed, can ensure the posotion closes to the mouth of needle plate and improve the high quality batching control on the fabrics;

9.The humanity developped function of double racking within 1 line. it improved 50% effiency after adopt this function;

10.The sole design of sinker self-protection control technology, it ensures that when the needle bed moves left and right, the sinker will not be damaged. With the new sinker control structure (which  can adjust up, down, left and right directions) , sinker can control with the yarn perfectly. 

11. Separate sinker control system, every system can makes transfer, knitting and filling ect to be finished in one line.

12.Patentable needle bed gap adjustable function, it can with three  working station in different lines of same knitwear. It can equipped with specific multi gauge needles, then it can knit different gauge knitting styles in one machine.It reaches “ ONE MACHINE WITH MULTI FUNCTION”  (14G can working with 1.7mm~2.0mm~2.3mm gap; 7G can working with 3.7mm~4.1mm~4.5mm gap,  etc.)

13. 9-14g of D3S type machine can equipped with filling feeders to knit filling type knitwear.

14. Equipped with computerized oiling system for long jack and spring jack needles,it can refueling at regular time and fixed quantity to reduce wear of cams and jacks, and extend service life.


1.Adopt the latest A8 high-speed processor, to bring you unparalleled operational experience;

2.LCD industrial display is adopted in the screen, and USB and internet are used as transmission modes. Users can save a great deal of pattern documents and use from time to time in line with the production requirements;

3.Monitoring screen: it is able to display all knids of working parameters and the numerical value for the knitting lines. Meanwhile, it adjusts from time to time at the moment of machine running; therefore it can maximally operate and save time;

4.Platemaking system and control system are researched and developed independently; the software, as the free configuration, can be upgraded conveniently;

5.Multi-Language operation versions: it supports Chinese, English and other languages; meanwhile it can set other required languages as per the customers' requirements;

6.Support design colour code tight tuck 2, support contiguous and multi piece knitted. Stitch can fine adjust seperately and edge correction;

7.Support the function of current detection , provide a warm reminder for maintenance personnel to quickly identify the fault source;

8.Batching system:Computer programs command, stepper motor control,128 segments tension selection. It is able to select the moment of force to assist the roller for the purpose of providing effective tensile force for thick piece of clothes;

9.Support the automatic correction of transfer stitch value, can avoid yarn broken and missed stitch when do tighter knitwear, improved qualification rate of knitwear.

10.With recovery function of factory setting,  it can recovery easily when by error operation.

11.The intelligent waste-yarn function, it ensures the minimum use of waste yarn in continuous knitting.
