Chemical fiber processing technology

Abstract

The invention discloses a chemical fiber processing technology. The chemical fiber processing technology comprises the following steps of S1, melting raw materials; S2, melt mixing; S3, filtering; S4, metering; S5, spinning; S6, cooling and forming; and S7, bundling and oiling. Through the arrangement of a heater, a stirring box and an extrusion device can be fully heated, and materials can be melted more quickly; through the arrangement of air outlet holes, hot air is diffused from the middle to the two sides, and the area, making contact with the hot air, of the middle of the materials is increased; and by virtue of the arrangement of air outlet holes in stirring blades, the area of hot air contacting with the outside of the material is increased, the hot air contacting with the middle and the outside of the material is uniform, working efficiency of the device is improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber production, and in particular relates to a chemical fiber processing technology. Background technique [0002] Chemical fibers are made of natural polymers or artificially synthesized polymers as raw materials, through the preparation of spinning dope, spinning and post-treatment processes, and are made of fibers with textile properties. The chemical fibers are soft and shiny, like cotton. As soft as fiber, as smooth as silk fiber, with good hygroscopicity and air permeability, etc., it is very popular among people. In the production of chemical fiber, it is necessary to extrude the raw material of chemical fiber, and process the raw material of chemical fiber into the silk or silk that people need. The strip shape is convenient for the production of the next process. In the process of extrusion, a chemical fiber extruder is needed, but now the general extruder has a single function, troubl...

Problems solved by technology

[0002] Chemical fibers are made of natural polymers or artificially synthesized polymers as raw materials, through the preparation of spinning dope, spinning and post-treatment processes, which have textile properties. Chemical fibers are soft and shiny, like cotton. As soft as fiber, as smooth as silk fiber, with good hygroscopicity and air permeability, etc., it is loved by people. In the production of chemical fiber, it is necessary to extrude the raw material of chemical fiber, and process the raw material of chemical fiber into the silk or silk that people need. The strip shape is convenient for the production of the next process. In the extrusion process, a chemical fiber extruder is required. However, the general extruder has a single function, troublesome feeding, relatively large power consumption, and time-consuming and labor-intensive increase in production. cost
