I lost another shirt this week. Have about 8 holes in the front of the shirt. First does activator powder eat holes in shirts? Teh only reason I ask is because I have been working on my pool lately too. Second how do you keep from this happening. I am looking into a flip top bottle to put the powder into. I think my problem is taking the lid off of the quart container I keep in the mixing area. When I take the lid off any powder from the lid always goes flying.
Thanks in advance

no one else has this happen. If you get activator powder on your shirt does it eat the shirt after you wash it.
-
I'd wager it's the pool chems.
-
Im going to do a test.

Science is totally rad.
-
well a quick test. Straight powder sprayed with water and then dried with a heat gun made the shirt in that area weak. I could easily rip it in that area. The powder did DC the area when heated with the heat gun. My shirt is not DC around the holes. I will let it sit on the fabric and dry normally and see if it still make the fabric weak with out DCing the area. (no heat gun).
-
Yeah, heat gun may be a factor. When we first started testing colors with it I was surprised at how easy it was
to scorch if not burn fabric.
-
Chlorine/bleach will do that if you were using it with your pool
-
Ok second test did nothing. I did a scoop of powder then sprayed it with water and let it sit all night. To day the fabric is as strong as normal.
-
we had a shirt we used for testing that was printed over and over again in the same place than sent through a very hot dryer (400+).
it started falling apart in the areas where we laid down a lot of ink.
so there is something to this story . . .

Well, ZFS is def doing a chemical bleaching action. Makes sense that too much would break down fibers. Perhaps this is, in part, where the recommended six percent limit comes from.
