Black Color Fade in Patches on Shirts?

[Mungo Spike]

We use an expensive, premium grade detergent that contains an oxygenated bleach to do our WDF orders. The stuff works great, but we have one customer who complains that patches on her sweatshirts and sports shirts are being damaged.

I examined the shirts she's talking about; the black colors fade to brown on sewn-on patches that contain black fabric, or in lettering that contains black material. The black fabric sometimes makes up the trim around the patch and sometimes it is the letters in a sport's team's name, for example. Everything else on the shirts is fine.

Is there something about the oxygenated bleach that causes the damage? Is the fabric itself at fault? Or is there another problem?

Your thoughts?

Thanks ... Mungo

Which detergent is it exactly? I've personally seen Tide w/Bleach do this so I wonder if thats not what your using. I'd love to use a product with Bleach but I've not seen anything that doesn't cause the fading your describing. Maybe Gain w/Bleach? Anyone have anything that they don't have fading problems with?

I use a powdered product called Clean Sudz that I buy from my laundry supplies company (Richclean) in 50-lb bags. Drycleaners use this premium soap too.

Is Clean Sudz more expensive than Tide, more effective?

Only this one customer has the problem?

I pay $35.95 for a 50 lb bag, so I think it's less expensive than buying Tide.

I only have one customer who voiced the problem - don't know if there are others who haven't said anything.
