Using Movable Air Ring Control Ring To Reduce Yarn Mao Yu

Do spinning hairiness It will have adverse effects on spinning process, and will also cause some defects. The balloon control ring divides the larger air ring into 2 smaller air rings, and maintains stable and normal gas figure under the small spinning tension, thereby reducing the friction degree and frequency of the collision between the air ring and the spacer plate, and significantly reducing the yarn hairiness. The movement form of the balloon directly reflects the spinning tension, affects the yarn's evenness and broken ratio. After the balloon control ring is added, the shape of the balloon is relatively stable, which improves the yarn quality and reduces the breakage rate. At present, domestic cotton spinning frames seldom use air ring, but with the development and application of high-speed spinning and spinning doffer, it is imperative to configure air ring on ring spinning frame.

The balloon control ring divides the larger air ring into 2 smaller air rings. The transposition spinning is that the spindle does not spin at its corresponding front roller position and can maintain stable and normal gas figure yarns under the small spinning tension while spinning at the adjacent front roller position. The spinning principle is to pass through the state, thereby reducing the degree of collision and friction between the air ring and the spacer plate, and changing the twist triangle between the drafting unit and the twisting winding unit to change the twisting triangle to significantly reduce the yarn hairiness. The motion form of the balloon directly reflects the shape and size of the spinning, so as to better control the yarn tension in the twisting process, affect the yarn's sliver and breakage ratio, and easily cause the accidental elongation of the yarn. Therefore, we should make full use of the advantages of transposition spinning to improve the yarn hairiness, and try to avoid the deterioration of the yarn and the increase of the broken ends. A new idea is put forward in this paper, which is to install a movable air ring control ring on the basis of transposition yarn path.

The addition of a removable balloon control ring can reduce well. yarn Hairiness, which is because the balloon control ring not only makes the yarn balloon form divided into 2 smaller air rings from a larger air ring, but also makes the shape of the air ring always divided into 2 circles with nearly equal height, and the tension fluctuation is also reduced to the minimum. This makes the yarn shape of the output roller to the yarn guide hook stable, the centrifugal force of the yarn outward movement decreases, and the outward transfer of the yarn decreases, which is bound to reduce yarn hairiness to a certain extent. On the other hand, the shape of the balloon is stable, which reduces the degree of friction and the number of collisions with the spacer plate, and further reduces the yarn hairiness. Practice has proved that under the condition of high-speed operation of the ring spinning frame, the movement of the balloon is one of the main reasons for the increase of the broken ends. This is mainly manifested in the high speed, the movement of the balloon is significantly deviated from the scope of the normal balloon requirement, so that the tension of the yarn increases significantly, and the balloon lacks a certain elasticity, which weakens the ability of the yarn itself to bear the change of tension.

Removable Balloon control ring The reduction rate of hairiness for normal yarn path is over 20%; for the transposition yarn, the yarn Mao Yushu of the left commutator spinning is significantly less than that of the right transposition spinning, in which the moveable balloon control ring reduces the hairiness rate of the left transposition spinning 19.53%, while the hairpin reduction rate of the right transposition spinning reaches 30.56%. When spinning fine tex yarn, the yarn hairiness of the transposition yarn path is obviously smaller than that of the normal yarn path. This is mainly due to the change of the shape of the twisting triangle area by the transposition yarn path, thus increasing the pre tension of the yarn in the yarn. After adding the movable air ring control ring, the yarn hairiness of the 2 yarn paths decreased significantly. The movable balloon control ring can stabilize the shape of the air ring, reduce the yarn hairiness caused by the friction between the air gap and the spacer plate and the increase of centrifugal force. On the basis of transposition spinning, adding movable air ring control ring is a kind of spinning method that is worth popularizing and reducing hairiness.
