Description
Technical Field

At present, the effect of removing light components is a main method for solving the adhesion problem, namely, a layer of bundling agent is generally coated on the surface of fibers, silicone oil drops inside the bundling agent are blocked between the fibers and fiber monofilaments to form heat transfer and mass transfer gaps, excessive bundling of the fibers is prevented, and light components emitted from asphalt in the processes of spinning, pre-oxidation, carbonization and the like are prevented from volatilizing and diffusing in the gaps among the single fibers of the fiber bundles. However, the adhesion of the silicone oil droplets to the surface of the fibers causes the diffusion of substances and heat on the surface of the fibers in the adhesion area, as well as the aggregation of light components on the surface of the fibers, resulting in local non-uniformity and even defects of the fibers during the fiber treatment.
On the other hand, if a silk basket is adopted to collect the asphalt-based carbon fiber in the spinning process, namely, the silk bundles of the spinning asphalt from a spinning machine stretch forwards and fall into the silk collecting basket under the action of wind force, the silk bundles fall into a frame in a certain pattern in the plane two-way movement process of the airflow silk arranging and the silk basket, and due to the reciprocating steering movement of the fiber basket, the silk bundles can form a plurality of small bends and spirals; these small bends and spirals are not removed in time, and carbonization can solidify and shape, but when tension is applied to carry out drawing or large curvature turning in graphitization and post-treatment processes, the fibers are brittle broken at the small bends to generate fuzzing, even the brittle breakage of the whole bundle of fibers, so that the fibers must be removed before pre-oxidation.
