SPINNING APPARATUS FOR SHEATH-CORE BICOMPONENT FIBERS

摘要

Improvements in the construction of apparatus for spinning double-component fibers of the core-shell type with a single row, comprising a vertical stack type distribution assembly, having spinning chamber feeding chamber plates and a surface of outlet for two fibrogenic spinning solutions, characterized in that a hole plate immediately adjacent to said outlet surface is provided and, separated therefrom, a spinneret with fiber-forming holes, where said fiber-forming holes are arranged in rows above the plates of supply chambers of spinning solution of the vertical stack that feeds one of the two spinning solutions, the holes being arranged in said plate of holes in rows so that; a set of rows is located directly above the plates of spinning chamber feeders, for a spinning solution, with each hole aligned with a corresponding fiber forming hole in said spinneret plate and another set of rows is directly located above the plates of spinning solution feeder chambers, for the second spinning solution, with the holes therein arranged at a mid-point between holes of said first set, whereby the spinning solution flowing through said first set of holes of said orifice plate, forms the core forming component of said fiber and the other spinning solution is directed by lateral flow through the space provided to exit as a sheath forming component of said fiber.
