A kind of polypropylene polyethylene composite fiber spinning equipment

Abstract

The invention discloses a polypropylene polyethylene composite fiber spinning equipment, comprising: a constant temperature and constant humidity spinning and crystallization equipment, the constant temperature and constant humidity spinning and crystallization equipment comprises an inert gas storage device, a crystallizing device and a surface cooler. The air outlet of the inert gas storage device is connected with a refrigerator, and the air outlet on the refrigerator is connected to the surface cooler, which is driven by the air conditioner; One side of the crystallization tube is provided with an air inlet pipe which is connected to the air outlet of the surface cooler; the other side of the crystallization tube is connected to the return air outlet, and the end of the return air outlet is connected to the inert gas storage device; one end of the surface cooler is connected to the refrigerator through a pipeline , the other end is connected to the crystallization tube through the pipeline; the air pump and the reflux cooling device are installed on the return air outlet pipe. The invention solves the problem that the existing technology cannot accurately maintain constant temperature and humidity, cannot properly adjust the temperature, and has poor heat exchange efficiency and cannot be adapted to produce different types of composite fibers.

Description

technical field [0001] The invention relates to the field of rare earth electrolyte particle processing equipment, in particular to a polypropylene polyethylene composite fiber filamentation equipment. Background technique [0002] At present, in the spinning production process of the existing composite staple fibers, a spinning and crystallization equipment is first required to crystallize the plastic dope into the filament. In the whole process of composite polymer fibers, the stable crystallization point of filaments needs to be controlled. [0003] The spinning crystallization process needs to be crystallized in a stable environment created by an equipment. Since the density of polypropylene fiber is lower than that of water, the surface of the filament is not smooth, and the filament is easy to fly and break. The cooling method and the air-cooling method need to be cooled in a long and narrow air duct. The temperature in the air duct of the existing spinning crystalliz...
