Most of the superfine fibers obtained at present are solid fibers with homogeneous components and core-shell structures, the number of hollow superfine fibers is very small, and the conventional hollow superfine fibers have the disadvantages of high process cost, complex operation, low efficiency and low overall performance, and do not have the practical significance of industrial mass production.
