Problems solved by technology

But obviously, it is extremely difficult to load a large amount of media into the fabric in both methods
[0005] 2. Excessive media loading on the fabric will inevitably lead to a decline in the textile performance of the fabric
And too much load medium will inevitably affect its textile performance, which is not conducive to the large-scale application of the product

Abstract

The invention relates to a preparation method of a polyamide textile material with good electromagnetic wave absorption ability in an ultra-wide frequency spectrum range. The preparation method comprises the following steps: selecting a nickel zinc ferrite nano-rod and nano-particle mixture as a wave absorption medium, wherein the diameter of the nano-rod is distributed in a gradient manner; adding the nickel zinc ferrite mixture to deionized water, and uniformly stirring with an ionic liquid as a dispersant to prepare a ferrite wave absorption medium source dispersion; carrying out surface pretreatment on polyamide long lines by adopting an anhydrous ethanol and acetone mixed liquid; putting the treated polyamide fiber long lines in the ferrite wave absorption medium source dispersion, and fully stirring and mixing above solution; and cleaning the polyamide fiber long lines adsorbed with the nanometer nickel zinc ferrite, and drying the cleaned polyamide fiber long lines adsorbed with the nanometer nickel zinc ferrite to obtain the polyamide texture material. The electromagnetic wave absorption rate of the texture material in an ultra-wide frequency spectrum range of 100MHz-10GHz is not lower than 30dB, so the polyamide textile material is especially suitable for some weak physique people, such as pregnant women, to use.

Description

technical field [0001] The invention belongs to the technical field of preparation of nanometer materials and functional textiles, and in particular relates to a preparation method of a polyamide-based textile material with good electromagnetic wave absorption capacity in an ultra-wide spectrum range. Background technique [0002] Electromagnetic wave pollution will seriously endanger human health, especially for some weak people, such as pregnant women. In addition, electromagnetic waves will cause serious harm to the normal operation of communication equipment and electrical and electronic equipment. In the military and communication fields, the leakage of electromagnetic waves can also cause leaks. Therefore, the development of various electromagnetic wave protection materials has always been a research hotspot, and it is also a market hotspot. Especially textile fabrics with anti-electromagnetic radiation function are in great demand in the market. Because in daily li...
