Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber spinning, in particular to a high-efficiency cooling device. Background Art

[0002] The fiber spinning process is to dissolve the fiber-forming polymer in a solvent into a solution, or heat and melt the fiber-forming polymer slices in a screw extruder into a melt, and then enter the spinning machine after the pre-spinning preparation process. The spinning solution or melt is quantitatively, continuously and evenly squeezed out from the fine holes of the spinneret by a metering pump. The melt stream enters a lower temperature and cooling blowing environment to cool, solidify and form primary fibers. The primary fibers are then oiled and networked and then wound into a tube. After subsequent secondary molding processes such as stretching and heat setting, the finished chemical fiber spinning with applicability is obtained.
