Abstract
A method for manufacturing a nylon 66 hollow fiber includes steps as follows. A plurality of nylon 66 particles are provided. A melting step is provided, wherein the nylon 66 particles are melted so as to form a spun liquid. A fiber spitting step is provided, wherein the spun liquid goes through a hollow spinneret plate so as to form hollow nascent fibers. An evacuating step is provided, wherein the hollow nascent fibers are preliminarily solidified so as to form hollow half-solidified fibers. A cooling step is provided, wherein the hollow half-solidified fibers are cooled and solidified so as to form solidified fibers. A collecting and oiling step is provided. A drawing step is provided. A winding step is provided so as to obtain the nylon 66 hollow fiber.
