Therefore, adjusting the carding polyester raw materials suppliers parameters has a great impact on the sliver quality. Impurity pre-spinning impurities are classified as follows: large impurities, fiber fragments, and dust. Even if the linear velocity ratio of the surface of the cylinder and doffer decreases, the fiber transfer effect will increase, but if the doffer speed is increased, If it increases too much, the cohesion will decrease, and the transfer effect is closely related to the formation of fiber hooks. Therefore, the selection of good feed materials can reduce the level of impurities and reduce dust accumulation in the rotor. 4. When all other parameters are unchanged, only increasing the cover speed will increase the cover flowers.
The longer the fiber length and the higher the length uniformity , The more stable the spinning process. (Source: Internet). As the doffer speed increases, the cohesion effect increases. The strength of fiber air-jet spinning has a linear relationship with the strength of the fiber. Affect yarn quality.
Even if they can be removed by the carding roller, they may still deposit in the cotton condensation tank and cause flying flowers.2 twist is passed down to a special point of the rotor condensation tank, called the peeling point, there is one in the rotor condensation tank Bundle area where fibers are twisted. The strength and appearance of the yarn will be significantly reduced. Dusty deposition will also damage the evenness of the yarn and increase the hairiness of the yarn. Carding is the key process of air-jet spinning.
The following five main factors affecting the quality of air-jet spinning are analyzed: 1. Hooks, fiber loops, fiber pieces, and other deformations greatly affect the quality of air-jet spinning. In the process of air-jet spinning, the following tasks are mainly completed: opening and drawing the sliver to a single fiber state; removing impurities from the feed material; uniformly mixing the fibers; forming a sliver; agglomerating the fibers; improving uniformity through merging Degree; twisting; winding forming. 6. 2. By adjusting the speed of the cover plate or the content of the cover flower, a sliver of better quality can be produced with a cotton roll of ordinary quality. When the cylinder passes through the transfer zone, its surface speed is very high.
