Will fleece bleach successfully, or do bleaching chemicals react with the fabric? Answered

Will ordinary fleece fabrics de-colour if you use ordinary house-hold bleach?

Will the fabric survive intact?

Will ordinary hot water be sufficient to clean the bleach out of the fleece?

Fleece means wool or synthetic? Either way, wool would only suffer under concentrated bleach for a prolonged period, synthetic would be fine.

With regard to bleaching, it does depend upon the fibres. Wool would be surface-dyed and probably bleach quite easily. Synthetic is likely to be dyed throughout as a material so you'd not achieve it.

Hot water would remove domestic bleach.

If it's synthetic fleece, and bleach doesn't work, maybe excessive amounts of UV light would do the trick.

It's synthetic stuff I'm talking about, the sort of stuff that is often made from recycled plastic.

That's what I figured.  I've no experience bleaching it, but I hope it works for you!

With bleach, the important thing to know is:   is the material made of Cotton?   Any plant based fiber will break down fairly quickly when bleached ( I have some "spider-web thin" handkerchiefs to demonstrate this :-)

I'm heavily inclined to think that the plastic material is dyed throughout rather than surface-coated, so it would be an unfortunate "no".

By the same logic, it would be hard to dye as well...

I feel complications coming on...

Yes. Fibres such as cotton and wool will bleach and take dye, synthetics not so much so.

My sister's boyfriend (then) did have a go at turning his camo' jacket black with "motorbike-paint", it worked sort-of but not really...

Ach, a simple plan in my head is getting overly complicated.

I think I need to think it out again...

Lemonie's 100% right, but just for giggles and the love of the scientific method, I've put a swatch of black synthetic fleece in to soak in undiluted Clorox. I'll check on it when RavingChild and I get back from his Taekwondo class and let you know if it did anything at all.

If you don't mind my asking, what'cha making?

Gotcha. Say no more.
Anyway, the black fleece is still thoroughly black, and seems to have suffered no ill effects whatsoever from soaking in bleach for two hours. You'd never suspect that it had ever been bleached.
Hope this is helpful.

Oh yes, but you'd "bleach" it into dust trying.

Well, surely there's a midpoint before you get to that level of UV exposure!

Bleach will damage the fabric and possibly fade and/or drain the color out. But the fabric will definitely be damaged whether or not it is immediately apparent.

Lemonie seems to think no, could you try it on a small patch to prove him wrong? :p
