This is due to the limitation of the mechanical structure of the equipment and the natural accumulation of the material in the conveying process, resulting in uneven thickness of the cotton layer in the transverse direction. The uneven cotton layer entering the subsequent carding process will cause uneven carding effect. In the thick cotton layer area, the fiber is not fully carded, and there are more impurities and neps, and the fiber straightness is poor, which affects the strength and uniformity of the yarn; in the thin cotton layer area, excessive carding may produce a large amount of short fibers, reducing the fiber utilization rate and yarn quality.
