Slightly OT: Where do I find the black woven tape used in electronics?

[Dekatron42]

I've been trying to find the black woven tape used to tape connectors to each other to keep them connected and it is also use to tape cables down to the casing.

I am restoring some old electronics equipment where this tape has been used but the glue used on the tape has dried over the years and the tape has come loose.

There are thousands upon thousands of different tapes to be bought at places like Digikey and Mouser but I just don't know where to start and I hope that someone here can point me in the right direction.

Pictures of what you are talking about are always helpful. I can't quite imagine what it might be.

Gaffer's tape usually works well.

Maybe Tesa 51608 would do?

Pictures below from a new similar type of tape taken from my computer as I didn't have the old equipment available.

I remember a type of insulating tape from before PVC and more specialist tapes became common. 

It was a cloth tape impregnated with a black adhesive somewhat like tar. The adhesive went all through though maybe one side was a bit wetter than the other. The result when wound tightly was quite water resistant water would bead up on it, and there was enough free adhesive that you could smear it over and seal the surface completely.

This would have been about 1968 or so. 

I'm afraid I don't know where to get it but I'd search for cloth tape, cloth tar tape maybe.

Maybe this one ?

Search was 'cloth electrical tape waterproof' on duckduckgo.

What you describes sounds a lot like wiring harness tape.  It is impregnated with an adhesive, but it is not thick like in the pictures.  I used it on the wiring on my ancient MGB.

Search on Amazon for "car wiring tape" or "car harness tape"

It's sticky on one side, cloth on the other to stop all those rattles in cars!

good stuff.

You might also try searching for “friction tape”. I remember using that back in the days before PVC, and we also used it to wrap the paddle of our hockey sticks for better puck control!

Thank you for all suggestions, googling them all showed me photos of other tapes which finally led me to what I believe is the tape I am looking for and it is called acetate cloth electrical tape. 3M sells a type called "3M Acetate cloth electrical tape 11" https://www.3m.com/3M/en_US/p/d/b00017295/ which of course is quite expensive as it is 3M and I could only find it in stock in 6.3mm width (1/4"). However I found some other brands at transformer winding companies as it is also used to isolate between winding layers and also on top of the final winding layer. Since I won't be using it as an isolating tape I ordered a cheaper one from eBay (Chinese manufacturer used at a transformer winding company I know - if i just had thought about that first!).

The photo below shows one such tape from Amazon, unfortunately Amazon didn't have a single type of acetate tape in stock right now.
