Discharge on Triblend

[jvieira]

A few days ago I saw a picture on Instagram of a triblend tee with discharge printing. Having never done anything similar before, I ordered a pint of discharge ink and activator and tested it on a few shirts.

We tried on a triblend (sky blue), on a heather grey and on a 100% cotton black shirt.
Of all 3, only the black shirt came out discharged. Both other tees came out looking kind of burnt (oddly the blue shirt came out burnt in some places and still wet on others.

Does discharge not work on triblend and heathers or was our oven temperature too high (320º, 90 seconds)?

This is what we were looking for

You will have better luck getting that look by printing single pass Waterbased White versus trying to discharge.

Heather gray will not discharge as there is no dyestuff to displace. Many charcoal blends will however. It depends on fabric content and dyestuffs however many triblends work.

I would try out the CCI D-white.  We discharge triblends all the time.  We run our dryer at 340f with 2 mins in the dryer tunnel and have no problem.  We are running forced air gas dryer which makes a big difference and no flashing on the press.  I guess you have a IR dryer which sucks for water base discharge.  The same effect can be achieved also with a HSA white with one coat of ink.

 have had great luck with some of the bella/canvas triblend( berry and aqua worked real well ) and some of the next level triblends as well... gotta test , test , test

All anvil triblends will discharge nicely.

Is 320 the temp your dryer is set to or is that the actual temp of the ink when it's in there? We always try to keep the print at 320 for 2.5 min, but each ink manufacturer has its own specifications for curing.
We almost always use a mix of discharge white /discharge base with varying ratios depending on the the fabric and color. So with that, we get a good amount of blended shirts to discharge nicely including Next Level triblends and their CVC line, especially the heathered looking shirt colors. But the solid dark color blends usually don't work very well along with some blues and greens. Adding some white really can make a difference as long as the design permits and your customer is OK with it. But you should always wash test and keep good records of your process.
