Selecting Reasonable Carding Machine Can Improve Yarn Quality.

From international

In view of the development trend, Xilin fixed cover has become part of the new carding machine.

With the in-depth study and popularization of Xilin fixed cover in China, the theory and practice prove that the carding machine has many advantages before and after installing tin forest. The technical pformation is an inevitable trend of technological progress.

After several months of market investigation and operation for 3 months, the results show that the quality of the resultant yarn has been obviously improved.

Practice shows that the qualified rate of cotton web is obviously improved after adding fixed cover plate, and the degree of parallelism of the fiber in the cotton net is better. The strong combing of the front and back fixed covers reduces the cross and kink between the fibers, and ultimately reduces the formation of potential neps in the cotton net.

The rate of impurity removal of the cover plate is 0.85% higher than that before the modification, and the impurity removal efficiency is increased. This indicates that the cotton roll is pre combed after fixing the cover plate, providing the basis for fully combing the rotary cover plate, so that impurities and fibers can be easily decomposed in the work area of the cover plate.

The number of Neps in the sliver is reduced, and the cotton fibers are further combed into the work area of the cover plate after the preset carding of the cotton sheets, which reduces the chance to generate neps. The distance between the fixed cover and the outlet of the cylinder after the cylinder is gradually narrowed from wide to narrow, which prevents the fibers from being rolled into radish filaments or forming neps.

The increase in the number of impurities in the sliver is caused by the preset carding of the rear fixed cover, because the new fixed cover has sharp edges and strong combing, which makes the large particles broken into many fine impurities, making it difficult to comb in the carding process behind.

The CV value of yarn Worcester can be reduced by 0.69% after installing the fixed cover. This shows that the Xilin fixed cover has a positive effect on improving the comprehensive quality of the yarn, and the blackboard neps reduce by 6. This is consistent with the results of the sliver.

In addition, the number of impurities in the blackboard is reduced by 3 grains after modification, which seems to be in contradiction with the increase of impurities in the raw strips. The author thinks that this is mainly due to the more thorough combing of cotton fibers, the improvement of the sliver structure, and the breakage of the fine impurities in the process of post spinning.

Before and after the carding machine is installed

After fixing the cover, the carding ability of the carding machine is improved, and the yarn quality is improved.

Metal card clothing is one of the key spinning equipment, it has the heart of carding machine.

Its smoothness, smoothness, sharpness, wear resistance and quenching uniformity (commonly known as five degrees) directly affect the carding efficiency and stability.

If the separation of the fiber web is high after the combing, the cleaning of the sliver is better and the structure is clean and uniform, then the downstream process will improve the product quality, reduce the yarn miscellaneous defects and improve the appearance of the fabric.

However, some cotton spinning enterprises have disadvantages such as low ability to pick fibers from card clothing, low impact on carding and so on.

Therefore, when making carding cloth, textile manufacturers must make reasonable choices and pay attention to matching so as to give full play to their carding efficiency.

For the A186 series carding machine, the four matching of the needle roller, the cylinder, the cover plate and the doffer clothing are generally concerned. Now the FA series carding machine adds the front, the rear fixed cover and the thorn roller preset combing board, which is called the seven matching, but the four matching is still the foundation.

For this reason, since April 2008, our factory has replaced the card clothing of the FA224 high yield card, and has made certain results in comparison with the domestic and foreign famous products.

In the first 6 months of the use of ~8, all kinds of card clothing can maintain good combing efficiency and little difference. However, with the extension of the use time, the regularity of the increase of neps remains to be observed.

Domestic needle clothing has long been able to meet production requirements under normal circumstances.

When producing high count carding Combed Knitting Yarn with high production carding machine, the GRAFSPACETOP can be used for the flat card clothing, and the rest can be matched with GERON card clothing, so that the tin linen can reduce the times of grinding.

And the neps will not deteriorate too much.
