Problems solved by technology

However, in practical application, some problems also appeared, such as: cold pad-batch dyeing technology is applied to cloth dyeing, because the cloth itself has continuity, but when it is applied to loose fiber dyeing, because the loose fiber itself does not have continuity, even through The web forming machine spreads the loose fibers into a fiber net. During the process of immersion, water rolling, and stacking, fiber web breakage and loose fiber shedding are also prone to occur. On the other hand, padding dyeing is used, which is similar to Compared with the dyeing of the dyeing vat, its dyeing effect is relatively poor, and it is prone to uneven dyeing. During the stacking process, we also found that there are some uneven dyeing, especially the phenomenon of discoloration at both ends.

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 ...

Abstract

The invention relates to a cooling stacking technology, and belongs to the technical field of loose stock dyeing. To-be-processed loose fibers, fiber webs or similar materials are subjected to immersion, liquid squeezing and rolling, after rolling, the loose fibers, the fiber webs or the similar materials are packaged in a closed environment, rotating and stacking are carried out, after the rotating and stacking are completed, unrolling is performed, and the loose fibers, the fiber webs or the similar materials are subjected to the next process. The technology is applied to the cooling stacking color fixation of the loose fibers, fiber webs or similar materials, and has the advantages of uniform dyeing, continuous processing and the like.

Description

technical field [0001] The application relates to a cold pile process, which belongs to the technical field of loose fiber dyeing. Background technique [0002] The traditional bulk fiber dyeing process is to put the bulk fiber to be dyed into the fiber cage, then put it in a cylindrical dyeing vat, add water, dyeing chemicals, auxiliaries, etc., and carry out pre-treatment, dyeing, post-treatment and other processes . The main disadvantages of this process are: 1. Each process requires a large amount of water and electricity, the production cost is high, and the dyed liquor after each tank must be discarded, the sewage treatment is difficult, the discharge is large, and the environmental protection is relatively low. Poor; 2, can only dye one cage by one cage, can't realize continuous industrial production, and production efficiency is lower. [0003] With the development of technology, at present, the continuous dyeing process of bulk fiber has been widely studied, such ...
