Description

Technical Field

[0001] The utility model relates to the technical field of spinning tube cleaning, in particular to an automatic cleaning device for a viscose filament horizontal spinning tube. Background Art

[0002] The viscose filament spinning tube is a slender tube part made of quartz glass. In the production of viscose filament spinning, the viscose thin stream is squeezed out from the spinneret hole and flows into the spinning tube together with the spinning bath liquid. The viscose thin stream and the unused fresh bath liquid undergo diffusion, neutralization, coagulation, decomposition and other reactions in the spinning tube. The main components of the spinning bath liquid are a mixture of sulfuric acid, zinc sulfate and sodium sulfate. In the process of reacting with the viscose thin stream, a variety of inorganic salts will precipitate. Such inorganic salts are easily deposited and attached to the inner wall of the spinning tube to form acid scale. Over time, the inner diameter of the spinning tube will be reduced, and the capacity of the fresh bath liquid will be reduced, which will affect the sufficiency of the reaction of the filament in the spinning tube. Therefore, in this process, high requirements are placed on the cleanliness of the inner wall of the spinning tube. The cleanliness of the spinning tube is a key factor affecting the later dyeing uniformity, spinnability, single fiber constant skin-core ratio and porosity index of the filament.
