Abstract

The invention discloses an annular blowing pipeline structure and an operation method thereof, and belongs to the technical field of spinning. The structure can provide specific circular blowing conditions, further improves filamentation performance, and is stable in spinning, simple in structure and convenient to use. The structure comprises a spinning equipment body, a yarn outlet pipeline is arranged under a spinneret plate on the spinning equipment body, the middle end of the yarn outlet pipeline is connected to an air outlet of an annular blowing pipeline, and an air inlet of the annular blowing pipeline is connected to an air source; and the air source comprises an air pump with a freezing dryer, and the air pump is connected to the air inlet of the annular blowing pipeline through the freezing dryer.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a ring blowing duct structure and an operation method thereof. Background technique [0002] Ring air blowing is an important cooling process of chemical fiber spinning, and it is a key process to ensure the performance index of fiber as-spun yarn. Uniform cooling can greatly increase the yield of high-quality yarn. During the spinning and forming process of PBO fiber, specific surrounding blowing conditions are required, otherwise normal spinning cannot be carried out, and if the surrounding blowing conditions do not meet the requirements, it will cause hairy filaments and broken filaments when PBO fibers are raw. [0003] Therefore, there is an urgent need to develop a surrounding air duct structure and its operation method to solve the problems in the prior art. Contents of the invention [0004] The purpose of the present invention is to provide a ring blowing pipeline st...
