Preparation method of functional fiber

Abstract

The invention relates to the technical field of preparation of functional fibers, and provides a preparation method of functional fibers, which comprises the following steps: according to the cross section structure of the functional fibers, manufacturing a preform rod consistent with the cross section structure of the functional fibers; and stretching the preform by adopting a hot drawing process to form the functional fiber. The preparation method of the functional fiber provided by the invention comprises the following steps: firstly, manufacturing a preform consistent with the cross section structure of the functional fiber according to the cross section structure of the functional fiber, and then stretching the preform by adopting a hot drawing process to form the functional fiber. Compared with the functional fiber prepared by the method in the prior art, the material on the surface of the functional fiber is not easy to fall off, the wear resistance is better, and the failure of the functional fiber is not easy to cause. Moreover, compared with the functional fiber, the size of the preform is larger, and the structural optimization design is more convenient in the stage of manufacturing the preform, so that the finally drawn functional fiber is stronger in applicability and higher in practical application value.

Description

technical field [0001] The invention relates to the technical field of preparation of functional fibers, in particular to a preparation method of functional fibers. Background technique [0002] Wearable products and portable devices have attracted widespread attention due to their various functions such as communication, health detection, and motion sensing. However, frequent battery replacement or charging can also be a huge inconvenience. And there is a lot of mechanical energy around the human body, such as motion, waves and wind. This also enables the fabric to continuously convert mechanical energy into electrical energy that can be used by wearable products and portable devices based on the principle of triboelectricity and electrostatic induction. [0003] In the prior art, a metal wire or polymer wire is used as the core, and then electrodes and dielectric layers are coated or deposited on the surface of the core layer to form functional fibers, and finally the fu...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention lies in the preparation method of functional fibers in the prior art. The coating material on the surface of the functional fibers made has poor wear resistance. The coating material on the surface of the fiber will fall off, resulting in the failure of the functional fiber, thus providing a preparation method for the functional fiber
