How can I change orange colored fabric to a beige or white color?  The
orange color was the color it was intended to be.  I tried bleach, it
didn't budge.

BestFoods makes RIT fabric Dyes- sold in USA grocery stores & ??? other countries

They make a Color Remover too

Strong bleach solutions can damage fabric

The Rit Color Remover mentioned by bobthedispatcher-ga works quite
well on cotton fabrics, as does a similar product called Spectralite.
I've used both these products on cottom denim and on cotton
tee-shirts, with good results and very little damage to the cloth.

If your fabric is anything other than 100% cotton, you are probably
out of luck. Many synthetic fabrics will dissolve completely before
they will yield up their color.

Please substitute "cotton denim" for "cottom denim" in my comment above.

hello
 can you let me know the type of fabric you have ? natural or
synthetic?The stripping of a color from a fabric will depend on this
 
Regards

The best people to ask about this are the people who deal with colours
every day. How about asking a fabric manufacturer, or perhaps the
fabric design department of an art college near you?

NB. I noted the title of this question was regarding the removal of
permanent colour from fabric. I can't help pointing out that if it
could be removed, it wouldn't be permanent!

This is a beautiful 100% cotton with a sheen to it, and so far, it
does appear to be a truly permanent color.  I will try the Rit and
Spectralite products, and if that doesn't work, I will look into other
options.  I got many many yards of this at an auction for $.33 and
want to get it into a more relaxing color so I can make curtains for
the concrete walls in the basement.

Hello Maroonbells
Removal of color from a fabric is called "stripping" or "discharge".A 
search string-- stripping + fabric + dye + cotton
was used and some of the important results is given.
   www.val-chem.com/.The company's address is Val Chem Co.Inc,P.O.Box
338,Sayre,PA 18840.
The company's catalogue has a product called Liquid Stripper and the
description reads---Liquid product to strip dye from cotton.
Directions on request.

site offers  ready to use textile chemicals.
You could be in touch with these companies .
   You mentioned that bleach was not effective.Bleaching solutions
work by the oxidising action of chlorine present in the bleach
solutions.This means that your dyed fabric will in all likelihood
respond to reducing agents(sort of opposite of oxidising).
  The commonly used reducing agent for discharging color on cotton
fabrics is sodium hydrosulphite called "hydros"in the trade
 and thiourea dioxide called thiox.Since you have large quantities of
fabric, I suggest you consult the above companies
before using these chemicals.

  I wish you luck.I am curious about the outcome of your problem.If it
is not inconvenient, I would like to know whether you
succeeded.
Good luck once again
