Embodiment Construction

[0023] specific implementation plan

[0024] Method 1: According to the composition and preparation method of the fiber textile material with conductive and magnetic properties and dual-function functions, we have prepared three batches of fiber textile materials with double-function functions, and the preparation process is based on carbonyl thermal decomposition method. Production Parcel Fe 3 o 4 ζ—Fe 2N·α-Fe double-complex functional nano powder, then put the mixture into a high-speed mixer and stir it, and then melt it in the reactor after the material is mixed evenly. The treatment process is shown in Table 1, and then spin-oiling -The winding-stretching process adopts the method of the existing technology, and the twin-screw extruder equipment is used to process and produce semi-finished products, and the materials are processed into test products, and then the precision electronic device workshop and the confidential room are processed. Aspects of the application tes...

Abstract

The dual function electrical conductive and magnetic conductive textile fiber consists of nanometer dual function powder in 2-15 wt% and polymer in 85-98 wt%, and features that the nanometer dual function powder is composite zeta-Fe2N.alpha-Fe powder of size 20-80 nm and coated with Fe3O4 film. Compared with available technology, the dual function electrical conductive and magnetic conductive textile fiber of the present invention has the features of high electrically and magnetically resisting performance, especially capacity of preventing the harm of low frequency magnetic field on human body.

Description

[0001] Field [0002] The invention belongs to the field of preparing textile fiber materials with double complex functions. In particular, the preparation of textile fiber materials with double complex nano-functions of conduction and magnetism. Background technique [0003] The chemical synthesis method has been used to prepare textile fibers for many years, but the use functions of this type of textile fibers are limited to keeping warm and beautifying people's daily life. [0004] In the prior art, a high-tech preparation method has been used to implant or incorporate material powder particles with single-phase function into textiles such as cotton fiber, polyester fiber, nylon fiber, and spandex fiber, so that the fiber fabric products Possess a single use function. [0005] With the continuous development of science and technology, electromagnetic technology is widely used today, it will also cause certain "electromagnetic pollution" to the human living environment. F...
