Description
Technical Field
The invention relates to a centrifugal spinning device, belongs to the field of textile machinery, and particularly relates to a backrest type fiber preparation tank.
Background
At present, the forming method of the filamentous fiber mainly comprises melt spinning, dry spinning, wet spinning, electrostatic spinning, blow spinning, centrifugal spinning and the like.
The melt spinning is that the high polymer is heated and melted to support the melt, the melt is pumped into a spinning nozzle through a spinning pump, and then is sprayed into fine flow through a spinning nozzle pore, and then the fine flow is condensed to form fiber; dry spinning refers to preparing a polymer into a spinning solution, feeding the spinning solution by using a spinning pump, then spraying a liquid trickle through a spinning nozzle, and finally entering a hot air sleeve, wherein the solvent in the trickle is evaporated by heating, steam is taken away by hot air, and the high polymer is solidified into fibers along with the solvent; the electrostatic spinning is a spinning method for obtaining nano-scale fibers by spraying polymer solution or melt under the electrostatic action; the blowing spinning is that an electric furnace is used as melting equipment to melt raw materials, the melting raw materials are blown and stretched into fibers by high-pressure air or steam, and the fibers are collected to form finished fibers after being subjected to deslagging by a deslagging device.
Centrifugal spinning refers to a method of spinning a liquid storage tank filled with spinning solution (or melt) at a high speed, ejecting the spinning solution from a spinneret orifice under the action of centrifugal force, and collecting the spinning solution after solvent evaporation or melt cooling to form fibers.
In comparison, centrifugal spinning can obtain fibers with different materials and diameters by changing the composition and properties of spinning solution and spinning process parameters. Compared with other existing spinning processes, the method has higher production efficiency and a safer production environment in the aspect of preparing the micro-nano fibers. However, the existing centrifugal spinning process is relatively innovative to the fiber structure, and generally only can prepare the fiber with a single structure, even if the fiber is of a skin-core structure, the fiber is a single fiber in appearance, and the existing requirements are difficult to meet, such as the preparation of a back-to-back type fiber (two different fibers are tightly attached together back-to-back).
