AI Technical Summary
Existing hollow fiber production processes are costly and lengthy. Core-sheath composite spinning using biodegradable materials as cores has low anisotropy and cannot achieve efficient and stable mass production.
The component structure for producing high-anisotropy hollow fibers using air-assisted production employs a precision control system and aerodynamic principles. By utilizing multiple sets of air nozzles and distribution channels, a "skin-core" structure is formed, controlling the flow and pressure of compressed air to achieve efficient and stable production of high-anisotropy hollow fibers.
It has achieved efficient and stable production of hollow fibers with high anisotropy, solving the problems of high cost and low anisotropy, and meeting the market demand for high-performance fiber materials.
