Grapefruit Discharge Base.... 11/17

[DCSP John]

Just had a large organic super market chain tell me that their  previous
printer was using  a 'grapefruit' discharge base for their discharge printing, therefore foregoing the need
to add any 'formaldahyde' activator...   My guess is the base smells like grapefruit, just like my Rutland smells
like bubble gum...

To the best of my knowledge.. no discharge base that can be used with out an activator....

Thoughts?

?Grapefruit?

Sound like BS.

Seems I remember hearing somthing about someone haveing a discharge that was per-activated, and it could be kept on the shelve for six month or so. But don't remember hearing of a no activator ink.

i just learned about magna ULF discharge. Their activator for this ink doesn't have formaldahyde.

You can enzyme discharge fabric I believe, but hilariously enough I've only seen horseradish peroxidase as the mechanism, not grapefruit.   

I believe hydrogen peroxide and a peroxide precursor are also used so the it might not be as versatile as ZFS but not sure though, I'm no chemist.  It certainly depends on the dyestuff as all dc printing does.  I'm sure it would generate a tonal look at a minimum.

Would love to know who's making an ink and/or activator that uses this.

Regarding the non ZFS magna, that's been around for years right?  And hasn't worked well and is a haz ship was my understanding.

I couldn't help nerding out on this....grapefruit does contain peroxidase so but horseradish peroxidase seems to be more popular in biochem.

interesting to know.
As much as I would like to land a big super market order,
re-building our discharge program to accommodate one customer
seems like a stretch.... Just when it seems like we got thing figured out, along comes
the curve ball...

the previous vendor dyes everything in house, but apparently can't use certified organic inks
(think discharge) when  printing on darks. Something fishy going on here.

Check out this link. first and only certified GOTS printer in the US.

That's the previous vendor? 

It might be that they are printing a dye resist and then dyeing the shirts, sidestepping the need to discharge.

Cert organic inks are stupid expensive I hear, and dyeing is already super expensive and resource intensive so maybe that's why they are avoiding it.

I like the passive water heating system though.  Sounds like a nice way to cool the shop and get their base water temp closer to where they need it for dyeing.

Yeah, trying to get a discharge agent delivered to you that does not use formaldehyde is a nightmare. At least my experience in the States anyway. Remember, everything you touch / drive / sit on / whatever has formaldehyde in it so yeah, they will ship that like no tomorrow.

Oh, and if you want to be GOTS use Permaset. Most of their ink is. We use it not for that (it's an extra add on!) but they are an awesome company and their Super Cover line does the job unlike any other water base ink out there. Just my opinion.

They will be at Long Beach. Talk to them. There are a few other print shops on here that use them but they remain silent....

You could take some grapefruit juice and see what happens, I have printed with tumeruc and beet juice

There is a process called REHANCE. TS designs in burlington nc developed it and the inks and process is totally organic. I think they print everything on white then dye afterwords.

this place looks interesting! is there a good term for the "opposite of greenwash"? I'd take the tour if i was closer.
(of course, the act of even just making t-shirts in bulk is inherently NOT-green - requires energy, trucking, infrastructure, etc etc all just to make t-shirts that are 99% convenience/branding/not exactly essential - just imagine how much demand for us there would be an all-Amish world...)

sorry, jumped on my soapbox there for a minute.

Yea, Its a pretty cool operation. Eric Henry the owner is a really really great guy

[ZooCity]

Yes, the rehance was what I was thinking of.  Did they patent that? 

[RICK STEFANICK]

I'm sure. I believe they are the only folks that have access to it and run it.
