What is Zigzag cotton? The lint cotton processed by sawtooth gin is called Zigzag cotton. Zigzag cotton seed cotton is processed by sawtooth gin to remove cottonseed lint. Compared with cot cotton, it contains fewer impurities, a lower lint rate, uniform color, and loose fibers. We together look.
Here is the content list:
l The principle of Zigzag cotton.
l Craft configuration of Zigzag cotton.
The saw-toothed cotton gin grasps the fibers with the teeth of the saw blade, blocks the cotton seeds by the rows of ribs arranged in parallel, and uses the method of tearing to cut the cotton fibers along the roots and separate them from the cotton seeds. The sawtooth gin is violent, and it is easy to damage long fibers and produce processing defects, but the uniformity of fiber length is high, and the content of impurities and short fibers is low. Generally, the spinning cotton is mostly Zigzag cotton. Zigzag cotton is grasped by the high-speed rotating sawtooth on the sawtooth gin, to separate the fiber from the cottonseed, and the fiber aggregate is in a loose state. Since the sawtooth gin is generally cleaned, some short fibers, impurities, and defects can be eliminated. Therefore, Zigzag cotton contains impurities and fewer short fibers. Although the fiber length of Zigzag cotton is relatively short, the uniformity is better, the yarn strength spun is higher than that of top roller cotton, and the evenness is better. Since the sawtooth cotton gin is violent, it is easy to damage the fibers, and defects are easily generated during the rolling process. Therefore, there are many ginning defects such as neps, ropes, and fiber seed chips. The sawtooth cotton gin has a high output and is generally used by large cotton gins to roll fine-staple cotton.
Imported cotton is generally picked by machine, and there are many seed chips. The cotton ginning process is processed by multiple processes. Although the impurities in the raw cotton are fine and small, there are many neps and filaments, and there are many neps and impurities in the yarn. The process configuration should be based on reducing filaments and neps. Looseness and early fall, use the characteristics of the cotton box machine to increase the trash area; adjust the tearing speed ratio between the curtains, increase the density of the corner nails of the nail curtain, change the diameter of the small nails, and use the polygonal nails to open the cotton. Then reduce the amount of cotton fed, and correspondingly slow down the rotation speed of the porcupine, three wings, and comb beaters, so as not to damage the fibers. Such as individual raw cotton with a high short-staple rate and more neps? The porcupine beater can be changed to a carding roller to enlarge the separation distance of the drop zone, eliminate the short lint, or use the free blow to reduce the neps of Zigzag cotton. Appropriately reduce the ration of cotton laps, so that the feast cotton is fully loosened, but it is necessary to prevent the cotton lumps from rolling too much in the cotton box and increase the neps.
