H-fangcompact spinning accessorial equipment is four-roller device desigened formodification on traditional ring spinning.

HFJ compact spinning is four-roller device designed for modificationon existing traditional ring frames. Enjoying perfect structure, good workship,its performance is well accepted ever since its launching market.

When modifying old ring frame, no need to drill on the beam frame,no need to chang anything on the driving parts or parts beneath the beam frame,thus will not destroy any part of the machine. For the drafting section, onlychange roller stand, front bottom roller, flute pipe unit and add compactdevice. Then change fan case and change roving creel. In case of top ductsolution, even no need to change roving creel.

BasicRequirements for getting good result from compact spinning

1,Install traveling clearner.

2,Control temperature, humidity and dust content of the air in theworkshop:

   A,Temperature:25-30℃constantin all year long

   B, Relative humidity:  55%±5% for cotton

                      75%±5% for worsted

   C, Dust content of the air:<3mg/m3

StructureFeatures

1. Four-roller system, apron lattics are ofpositive drive.

2.  Negative pressure system adopt main blowerwith general air duct and filter net to avoild dirtying workshop.

3.  Modular design,6 spindles or 8 spindles inone unit.

4. Well-designed negativepressure distribution ensures consistency of airflow at each suction nozzle.

5.  The optimization designed suction nozzle onprofiled tube, good for fiber compact.

6.  Inverter control for both energy-saving andpressure adjusting for different yarn count spinning demands.

7.  Smoothly moving of the yarn is guaranteed bytension device of the apron lattice (patent product of H-FANG).

8. Closed-loop control onnegative pressure guarantee stable pressure during spinning.(For option)

9.  Auto-cotton striping device available foroption.(For option)

Benefits from HFJ compact spinning

1. For cotton yarn, over 60%3mmhairiness can be reduced.

2. Under the same process andworking condition, the tenacity of compact spun yarn is 5%-15% higher than ringspun yarn.

3. Decrease CV%, increasefibre availability.

4.  Higher productivity when producing sametenacity yarn than conventional spun yarn.

5. Yarn twist can be reducedby 5-10% while maintaining same yarn strength.

6. Better evenness ofdiameter and hairness.

7. 30% reduction in yarnbreakage in warping process.

8. Better abrasion resistanceof yarn leading to fewer breaks in weaving.

9. Singeing can be omitted incase of compact siro-spinning.

10. Reduction of pilling andbetter dye uptake in fabric.

11. Increase productivity,especially for high density fabrics produced in air jet looms.

12. More clear in fabrictexture for yarn dyed fabric, especially for warp-striped fabric.

13. Maintain tenacity whichlost during noiron finishing.

14. More smooth and soft infabric. 

15. Improve working conditions,reduceflyings in workshop.
