I chose Ian's original "Cyanotype Chemicals" thread for my post as it seems more appropriate than the latter thread on Cyanotype , given my general question concerns cyanotype chemicals but this time on fabric rather than paper

However if the mods feel it warrants a new thread by itself can they please move it and attach a new title. Thanks

I have been looking for any information I can find on whether a cyanotype print on, say, tee-shirt fabric can be washed and if so with what? Mild soap and by hand very gently or will it stand a machine wash and how many times, if at all,before it fades?

You'd think that as there are a few videos on cyanotype on fabric then someone would have covered washing such articles when dirty but if such videos or info exists out there then it has escaped me

The closest I came to an answer was from the Raychristofer who said that he wouldn't want to use bleach. OK by inference this suggests that it can be washed but nothing about what cleaning materials or washing method

Surely if you print cyanotype on a garment year then you are going to want to wash it at some stage?

There was one other video where the presenter used a brush to coat a tee-shirt and then covered all except that part exposed to the sun so that he could wash out the unexposed cyanotype soaked part to get a clean edge. So far so good except that once he had washed the unexposed fabric there still seemed to be a slight creamy stain where the cyanotype had been brushed on

Any info anyone else knows or has obtained is appreciated

Thanks

Mike

Hi Mike,

Not sure if you will have seen this article or not, but there's this one

http://www.alternativephotography.co...rics-or-cloth/

But other articles say no washing, however I did come across this product being mentioned
https://www.jacquardproducts.com/solarfast

which might be a substitute and give similar (?) results on fabric.

Right at the bottom of the instructions is this little paragraph

NOW YOU’RE DONE!
You’re print is soft to the touch, washable, lightfast and permanent



Hope it helps

Ian

Some interesting points in the articles Ian, so thanks for posting.

Also, from what I remember reading in the past, and I do know that it referred to paper cyanotypes, but it said if you cyanotype ever faded, then putting it back into the light again - i.e. a sunny day or with a UV light that you know works - and it will 'recharge' the image. Whether this would work with a washed fabric cyanotype, I don't know, but is worth checking out.

As for the four different prints, which have gone through various soaps etc. I like them ALL. They each have a different look and various images made on them, may suit each of these looks.

Also, Solarfast, I bought a bottle of the blue one some time back, but have only used it once or twice so far, using sunlight.

I noted that it said to put items on the surface coated with it, whilst still WET. When I tried it, I let it dry before putting various items, including a negative strip on it, as I didn't want to ruin any of the items and it came out fine.

Thanks. The 4 test fabrics turned out much as I might have expected. I suppose that any washing is bound to fade a cyanotype eventually. 10 washes sounds OK but for the life of a tee shirt isn't that long really

Clearly commercial style printing has to be the way to go. A pity but there we are. Still it was worth asking.

I decided a couple weeks ago to make a LED UV light source as I wanted to to get back to progressing some alt-photo ideas I had many years ago, including Cyanotypes. I have a Philips facial tan light which has worked successfully in times past however UV LED's are now available at reasonable cost so why not build one?

I got the idea from Matt Marash's utube video here.
See also Tim Laytons creation using the same devices.

It does not need to be this big but Matt and Tim use 8 strips available from Amazon. I suspect one could get away with 4 lamps if making smaller prints?

The 8 lamps cost me under £70 including shipping and taxes from the US. Just a little carpentry needed. Mine is in progress, I will post some images soon.

A great job Barry. I look forward to seeing some cyanotypes and other 'alts' from this soon.

Neil.
