Embodiment Construction
[0033] A kind of cold pile process of present embodiment, combines figure 1, the loose fibers, fiber webs or the like to be processed are immersed in liquid, squeezed into liquid, and rolled into rolls, and the rolled loose fibers, fiber webs, or the like are packaged in a closed environment and rotated and stacked. Roll back and send to the next process. Among them, in the process of turning and stacking, the rotating speed is 5-30r / min, and the cold stacking treatment time is 5-20 hours; and the turning method can be swinging with one point as the center, circular or similar with the center line of the fiber roll as the axis. Circular motion or a combination of the above two methods.
[0034] As a specific embodiment, combining figure 2 , the packaged fiber roll A (only a small amount of thin fiber layers are shown in the figure, but the solution is not limited to thin layers; the package structure is not marked) is placed on the rotating shaft 1a, and the rotating shaft ...
