Guide to Rotor Spinning Machine

 

What is the principle of rotor spinning machine?

Rotor spinning is a new spinning technology which uses air flow to condense and twist fibers in a spinning cup with high speed rotation. He does not use spindle, mainly rely on comb roller, spinning cup, false twist device and other parts. The carding roller is used to grab and comb the feed of the cotton strip fiber, through the centrifugal force generated by its high-speed rotation can throw out the grabbed fiber. The spinning cup is a small metal cup that spins more than 10 times faster than the comb roller. The resulting centrifugal action pushes the rotor out of the cup. According to the principle of fluid pressure, make the cotton fiber into the rotor cup, and form the fiber flow, along the inner wall of the cup constantly movement.

What is rotor spinning machine?

Unlike ring spinning, rotor spinning does not use spindle twisting, winding and forming. It mainly relies on several parts such as carding roller, spinning cup and false twisting device. The carding roller is used to grab and comb the feed fiber, and the centrifugal force generated by its high-speed rotation can throw out the grabbed fiber. The spinning cup is a small metal cup that spins more than 10 times faster than the comb roller. The resulting centrifugal action pushes the rotor out of the cup. According to the principle of fluid pressure, make the cotton fiber into the rotorflow cup, and form the fiber flow, along the inner wall of the cup constantly movement. At this time, there is a yarn head outside the cup, which leads out the fibers of the inner wall of the cup and connects them together. Coupled with the centrifugal effect caused by the high-speed rotation of the yarn tail of the cup, it is like “feeding” the cotton fibers while twisting the yarn, so that the yarn is connected with the fibers of the inner wall of the cup. Under the rotating tension of the yarn barrel, the yarn is wound continuously, and the process of rotor spinning is completed.
Characteristics of rotor spinning:
1. High speed
2. Large roll
3. Short process, reduce investment in infrastructure and equipment
4. Simple mechanism and no spindle, steel collar, wire ring
5. Compared with ring spinning, it can increase the yield exponentially

What are the advantages of rotor spinning?

The advantages of pure cotton rotor spinning:
1. The strips of rotor-spun yarn are good and even, with less impurity and yarn defects.
2. Rotor spinning yarn has high anti-wear strength and is not easy to pilling compared with ordinary ring spinning process.
3. The yarn has many twist, large tension and good elasticity.
4, Rotor spinning yarn structure fluffy, strong hydrophilicity, soft yarn, dyeing and hygroscopicity is better.

Twist Test Methods and Influencing Factors

Image
  Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To understand twist testing, you must first understand what twisting is. Twisting is a necessary condition for yarn formation. Short fibers can be made into yarns with certain physical and mechanical properties through twisting; filaments often need to be twisted in order to increase the tightness between single filaments, facilitate processing, and improve fabric properties. Number of twists Twisting is to cause two cross-sections of parallel straight fiber slivers to rotate relative to each other. The number of relative rotations of the two cross-sections is called the number of twists. Twist Twist refers to the number of twists per unit length of yarn . Twist coefficient In actual production, the twist coefficient is of

Combing Process in Spinning

Image
Before processing cotton, wool, and silk fibers into fabrics, the process of removing impurities and short fibers in the fibers with a combing machine is called combing. The texture, washability and durability of the fabric produced through this process are greatly improved compared with carded fabrics. The following introduces the composition of the combing machine and the combing process. The kinematic coordination relationship of the main parts on the combing machine is indicated by a dial. The disc is mounted on the combing machine and rotates synchronously with the cylinder, which is generally called the indexing disc. The index plate is divided into 40 equal parts along the circumference, and each equal part is 9°, which becomes one index. The working cycle refers to the time interval between the combing cylinder of the intermittent combing machine corresponding to the two actions of combing the whiskers. That is: the first row of needles in the combing cylinder goes to the botto

Garment Dyeing-Special Dyeing Method In Textile

Image
Garment dyeing is a relatively special dyeing process for textiles and garments. Many people may not know much about this dyeing process. In the impression of most people, textile and clothing products are dyed in the fabric period, and garment dyeing is a dyeing process that breaks people’s cognitive limitations on textile dyeing. ​What is garment dyeing ​Garment dyeing means that dyeing the one not in the fabric type but in the garment type itself. The garment type mentioned above include socks, towels, sportswear, shirts, plush toys (without fillers), T-shirts, pants, bathrobes, handkerchiefs, bath mats, carpets, scarves, etc. The material of these garments can be wool, linen, silk and cotton of natural fibers. But most garments are made of cotton or a cotton-rich blends. Garment dyeing imparts vibrant colors to garments. The clothes such as denim garments, tops, sportswear and casual clothing with garment dyeing can provide a distinctive special effect. Garment dyeing method Garmen
