Fiber spun yarn preparation method

Abstract

The invention relates to the technical field of fiber spun yarns, in particular to a fiber spun yarn preparation method. Fiber spun yarn preparation equipment is used in the method and comprises a base, a cooling device, a transmission device and a drying device; the cooling device comprises a cooling box body, a first motor, a belt pulley, a belt, a first driving shaft, a baffle, a sleeve and a collecting mechanism; the cooling box body is fixedly connected to the left side of the upper end of the base; cooling liquid is arranged at the bottom of an inner cavity of the cooling box body; and a plurality of round holes are formed in the upper ends of the left side and the right side of the cooling box body and are linearly distributed. According to the invention, the first motor is started to drive the belt pulley and the belt to rotate, the first driving shaft is driven to rotate, the first driving shaft rotates to enable the collecting mechanism to rotate, and fiber spun yarn is driven to be transmitted, so that the stability of the fiber spun yarn is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fiber spinning, in particular to a fiber spinning preparation method. Background technique [0002] Fiber spinning is dissolved in a solvent to form a solution, or the fiber-forming polymer chips are heated and melted in a screw extruder to form a melt, and then enter the spinning machine after the pre-spinning preparation process, and the spinning pump (metering pump) is used to spin the spinning The solution or melt is quantitatively, continuously and uniformly extruded from the fine holes of the spinneret, and this fine flow is solidified in water, coagulation liquid or air to form primary fibers, and this process is called fiber forming. During the spinning process, the fiber-forming polymer undergoes geometric and physical changes, such as the dissolution or melting of the polymer, the flow and deformation of the spinning fluid, and the gelation, crystallization, and secondary transformation during t...

AI Technical Summary

Problems solved by technology

[0004] (1) When cooling the fiber spinning, the traditional cooling method cannot cool it well, and it is not convenient to ensure the stability of the fiber spinning during the cooling process;

[0005] (2) After the fiber spinning is cooled, it needs to be dried, and the drying method of the transmission directly dries the surface, which will easily make the fiber spinning very brittle, and it will be broken with a little force
