What is the principle of rotor spinning machine?
Rotor spinning is a new spinning technology that uses air currents to condense and twist fibers in a spinning cup at high rotational speed. It does not use a spindle, but mainly relies on the pinion, spinning cup, false twist device and other parts. The carding roller is used to feed the cotton strip fibersto grasp and comb by the centrifugal force, its high rotation speed allows the grasped fiber to be thrown out. The spinning cup is a small metal cup that spins more than ten times faster than the pinion. The resulting centrifugal action pushes the rotor out of the bucket. According to the principle of liquid pressure, the cotton fibers get into the rotor cup and form a flow of fibers along the inner wall of the cup, which is constantly moving.
What is a rotor spinning machine?
In contrast to ring spinning, this is not the case with rotor spinning Use spindle turning, winding and shaping. It mainly relies on several parts like the carding roller, the spinning cup and the false twisting device. The carding roller is used to capture and comb the feed fiber and the centrifugal force generated by its high-speed rotting can cause the captured fiber to be thrown out by the rotation. the spinn cup is a small metal cup that rotates more than ten times faster than the pinion. The resulting centrifugal force pushes the rotor out of the bucket. According to the principle of liquid pressure, the... cotton fiber is fed into the rotorflow cup and form the fiber flow along the inner wall of the cup, which is constantly moving. At this point, outside of the cup, there is a twine head that guides the fibers out of the inner wall of the cup and binds them together. Coupled with the centrifugal effect caused by the high speed rotation of the yarn end of the cup, it is as if the cotton fibers are being \"fed\" and at the same time the yarn is being rotated so that the yarn is bonded to the fibers of the inner wall of the cup. Under the rotating tension of the yarn cylinder, the yarn is wound up continuously and the process of rotor spinning is completed.
Features of rotor spinning:
1. High speed
2. Big role
3. Short process, reduced investment in infrastructure and equipment
4. Simple mechanism and no spindle, steel sleeve, wire ring
5. In comparison With ring spinning, the yield can be increased exponentially
What is the rotor spinning process?
Rotor spinning process: cleaning — carding of cotton — strip rotor spinning
1. The role of the cleaning process
2. The role of combing process
4. The role of the roving process
5. The function of the spinning process
Dragging the pregarns by drawing to the desired count;
By twisting the yarn to obtain enough strength to allow the yarn to meet the needs of a particular style or feel of the fabric;
Wrap forming , practical for the next production process.
What is the difference between ring spinning and rotor spinning?
Ring SPINNING is the most common spinning method on the market. It refers to the drawn fiber strip of sliver or oar yarn in the previous spinning process, which is twisted and twisted through the ingot steel wire ring in the spinning process. is faster than the steel wire ring, and the fiber is twisted into spun yarn. It is widely used in all kinds of short fiber spinning system techniques, such as co-combining, combining and blending.
Features:
1. The ring of steel wire is driven from the spool through the strip of yarn around the steel pipe. For twisting,
2. through youe friction of the steel ring, its speed is slightly lower than that of the bobbin, resulting in winding, so the spinning speed is high.
3. The form of ring spinning is that the fibers are mostly conical spiral lines, which are transmitted inside and outside, so that the fibers are wound and connected inside and outside the outside of the yarn, and the structure of the yarn is firm, and the strength is high.
4, Suitable for thread making, knitting and other products.
Rotor spinning and ring spinning are new textile technology and old spinning technology. It is spun with a spindle and a steel bell and steel ring and drawn through rollers. Rotor spinning, on the other hand, is carried by rotor current and twisted at one end. In general, ring-spun yarn has higher strength, higher strength and better quality than rotor-spun yarn. The rotor spinning process is short, the protruding rotor issmaller, especially the viscose fiber can be seen more clearly, the fiber on the yarn does not break, but many rotors are wrapped in the yarn body, so the spinning cup yarn rotor is smaller, the count and twist can not be very high, and the Price is low.
In terms of yarn structure, ring spinning is more compact, while rotor spinning is fluffy and rough, suitable for denim fabric, rotor spinning yarn is generally thicker.
1 . Ring spinning and rotor spinning, one is the traditional textile technology, with a history of nearly 200 years, the other is the new spinning technology, with a history of 50 or 60 years.
2. Ring spinning is mechanical spinning that is drawn, twisted, and wound through rollers through a spindle, steel collar, and steel wire ring. Rotor spinning is done by a rotating cup running at high speed to create a vacuum and the Faser is transported by a rotor filling that is held and rotated at one end.
3. In general, ring spinning lends itself to better raw materials, fewer rotors, higher strength and better quality. The rotor flow spinning process is short, the raw material is short, the yarn wool, the number and twist can not be very high, and the price is low.
4. From the point of view of yarn structure, the ring bar spun yarn is firm and soft and is suitable for underwear fabrics, etc., while the fluffy yarn has a rougher style and is suitable for denim fabrics.
What are the advantages of rotor spinning?
The advantages rotor spinning of pure cotton:
1. Rotor spun yarn slivers are good and uniform, with fewer impurities and yarn defects.
2. Rotor spun yarn has high wear resistance and is not easy to pill compared with ordinary ring spinning process.
3. The yarn has many twists, large spabsorption and good elasticity.
4, rotor spinning yarn structure fluffy, strong hydraulics, soft yarn, dyeing and hygroscopicity is better.
What are the disadvantages of rotor spinning machine?
Poor tubular yarn formation, poor yarn drying, fancy yarn , broken end height, uneven strength and other problems.
