Abstract
Abstract The invention relates to a metallized textile material having a surface resistance as measured at 23° C./50% relative humidity in accordance with DIN 54 345 of at most 1×10 3 ohm. The invention also relates to a process for the production of such metallized textile material by currentless metal deposition, preferably at room temperature, thereon wherein the activation of the material is effected in a colloidal palladium solution, preferably at room temperature.

Claim 6
Dependent Claim
82 words
A process for the production of a metallised textile material having a surface resistance, as measured at 23° C./50% relative humidity in accordance with DIN No. 54345, of at most 1×10 3 ohms, which comprises introducing a textile material to be metallised into an acidic colloidal palladium solution containing tin(II)ions in excess, treating the material thus activated with an acid or alkali, and then coating the material in a metallising bath with metal by currentless deposition from an alkaline metal salt solution.

Dependent Claim
82 words
A process for the production of a metallised textile material having a surface resistance, as measured at 23° C./50% relative humidity in accordance with DIN No. 54345, of at most 1×10 3 ohms, which comprises introducing a textile material to be metallised into an acidic colloidal palladium solution containing tin(II)ions in excess, treating the material thus activated with an acid or alkali, and then coating the material in a metallising bath with metal by currentless deposition from an alkaline metal salt solution.
Claim 8
Dependent Claim
14 words
The process of claim 5, wherein said metallising bath is operated at room temperature.
Claim 9
Dependent Claim
16 words
The process of claim 5, wherein said metallising bath is an ammoniacal nickel or copper bath.
Claim 10
Dependent Claim
17 words
The process of claim 5, wherein said metallising bath is a copper bath alkalised with sodium hydroxide.
