(e) carry out the electroless plating second time, with the fiber surface of metallic tin plating in base material;
(f) armor coated, the protection plating is in copper layer and the tin layer of substrate surface;
(g) obtain finished product.
The utility model provides a kind of shielding textiles, is made of several fibrous woven together, and this each bar fiber is in copper layer of a kind of textile fiber surface coverage, and covers in addition a tin layer form outside the copper layer.
Wherein, the material of this textile substrate is nylon or PET artificial fibre.
Wherein, this copper layer and tin layer form metal conducting layer.
Wherein, this copper layer is the electroless plating layer.
Wherein, this copper layer thickness scope is 10 * 10
-6～200 * 10
-6Between the inch.
Wherein, this tin layer is the electroless plating layer.
Wherein, this tin thickness scope is 10 * 10
-6～200 * 10
-6Between the inch.
Wherein, in textile surface coating one deck resin protective layer of this tool electro-magnetic screen function, to protect copper layer and the tin layer on this textiles.
The textiles of above-mentioned tool electro-magnetic screen function, to interdict isolated electromagnetic wave and overflow loose by be electroplate with copper layer and the formed metal conducting layer of tin layer in each bar non-metallic fibers outside, and the tin layer is coated on outside the copper layer can prevent the copper oxidation, and the electromagnetic wave of shielding CF.In addition, this shielding textiles is more possessed flexibility, gas permeability and the tensility that general textiles has, and increases convenience and range of application thereof that the shielding textiles uses.
