DNA counterfeit-proof fiber together with spinning nozzle and method used to produced thereof

Abstract

A spinning nozzle for producing the synthetic fibers and a method for producing a DNA counterfeit-proof fiber by the spinning nozzle are provided. The spinning nozzle includes a polymer solution inflow passage and a pair of water inflow passages located at the both sides of the polymer solution inflow passage, wherein the polymer solution inflow passage and the water inflow passages are converged into a mixing outflow passage and a synthetic fibers are produced at the outlet of the mixing outflow passage. A method for producing a DNA counterfeit-proof fiber by the spinning nozzle includes the steps as follows. First, mixing a plurality of the DNA microcapsules with a material solution to produce a polymer solution. Then, to form a converging interface between the polymer solution and the two streams of acid-hydrolysis waters. Afterwards, causing the flowing polymer solution to converge with the two streams of acid-hydrolysis waters for producing the DNA counterfeit-proof fiber.
