Abstract

The invention relates to a method for preparing a light-colored conductive TiO2 whisker / superpolymer composite antistatic fiber and belongs to the technical field of functional textile materials. Themethod comprises the steps of taking a TiO2 whisker as matrix and a tin salt and an antimonium salt as raw materials, coating the surface of the TiO2 whisker with a layer of metal hydroxide by using aliquid-phase co-deposition method and transforming the metal hydroxide into a doped conductive metal oxide film under high-temperature treatment to obtain a light-colored conductive TiO2 whisker; fully mixing the prepared rod-like conductive TiO2 with a fiber-forming polymer and selecting corresponding spinning methods according to performance characteristics of different polymers; and finally obtaining a light-colored antistatic fiber. According to the method, the antistatic fiber is prepared by selecting the rod-like conductive whisker as a conductive filler; and due to the rod-like structure characteristic, the obtained fiber has a better corona discharge effect and excellent antistatic property besides the advantage of a whiteness value.

Description

technical field [0001] The invention relates to a light-colored conductive TiO 2 Preparation method of whisker / polymer composite antistatic fiber, specifically related to a light-colored conductive TiO based on corona discharge effect 2 The invention discloses a preparation method of whisker / high polymer composite antistatic fiber, which belongs to the technical field of functional textile materials. Background technique [0002] Static electricity, as a common physical phenomenon, has always been a major problem facing the textile industry. Its harm is not only reflected in the impact on people's clothing comfort and health, but also has hidden safety hazards in its processing and use. At present, there are many solutions to avoid these hazards, including antistatic finishing of fibers, blending or grafting of hydrophilic materials, and preparation of conductive fibers. However, these methods have irreparable defects and certain limitations. Specifically: (1) The cost of ...
