A kind of method of making above-mentioned polyion anti-electromagnetic radiation fabric is characterized in that, the steps include:
(1) weighing
The weight of weighing acrylic fabric according to the weight of acrylic fabric, adds deionized water in the container by bath raio 1:40-50 then;
(2) chemical reaction is bathed
Under constantly stirring, in deionized water, add copper sulphate, reductant, vulcanized sodium, succinate sodium sulfonate, surfactant, again with acetic acid adjustment pH value 4-4.5; Add clean acrylic fabric then, heat up, the operation of insulation, cooling process;
(3) washing
Adopt deionized water to wash;
(4) repeating step (2) and step (3), dehydration and drying and shaping then.
Reductant in the said step (2) is a sodium thiosulfate.
Surfactant in the said step (2) is an AEO.
Can after manufacturing technique, further carry out the lifting technology of dried fastness to wet rubbing, its concrete steps are:
1. in deionized water, add dried wet friction fastness improving agent, softener, bleeding agent; The consumption of said dried wet friction fastness improving agent, softener, bleeding agent is respectively 1-2%, 2-3% and the 0.2%-0.3% of polyion anti-electromagnetic radiation fabric weight;
2. the polyion anti-electromagnetic radiation fabric that makes is immersed in the mixed solution and stir;
3. dry down at 140 ℃ and got final product in 1 minute.
Compared with prior art, the invention has the beneficial effects as follows: soft, the good permeability of polyion type textile for anti electromagnetic wave of preparation, water-fast washing; The electromagnetic wave shielding performance reaches 35 dB, and promptly shielding rate reaches 99.96%.
