Description

Technical Field

[0001] The present invention relates to the technical field of fiber material processing, and more particularly to a novel fiber material and a stretching device thereof. Background Art

[0002] Fiber materials generally refer to three categories: natural fibers (including plant and animal fibers), inorganic fibers (such as asbestos and glass fibers), and synthetic fibers (such as polyester and polyaramid fibers). Fiber materials are widely used as insulation for superconducting and cryogenic winding wires due to their advantages: in superconducting magnet coils, they allow the coolant to penetrate all cross-sections, increasing the heat transfer area; and they ensure direct contact between the impregnating varnish or encapsulating adhesive and the superconducting fiber and composite layer.

[0003] Traditional plasticizing tanks rely on static immersion, the fiber speed is slow and the tank body needs to be extended, resulting in high energy consumption and high yarn breakage rate. In addition, the roller position is fixed during step-by-step stretching, which cannot adapt to materials of different fineness, resulting in uneven membrane yarn fineness. At the same time, the dry spinning process is prone to yarn breakage and increased hairiness due to insufficient humidity, and wet spinning has the problem of uneven atomization. Fiber threading relies on manual labor, and the cutting length consistency is poor. For this reason, we propose a new fiber material and its stretching device. Summary of the Invention
