Message: We got 3000 meter upholstery plain shaneel fabrics in verious colours we just like to black and brown dye

Is "shaneel" another name for chenille? Much more importantly, what fiber is your fabric made of? You should choose your dye based on the fiber content of the fabric. 

If it's made of polyester or acetate, it can be dyed only by boiling it with a type of dye called disperse dye; see "Dyeing Polyester with Disperse Dyes". 

If your fabric is made of nylon, it can be dyed with acid dyes or with disperse dyes. See "How can I dye nylon?".

If it is made of cotton or viscose rayon, it can be dyed with fiber reactive dyes, vat dyes, or direct dyes. See "About the Dyes: choosing the right dye for your fiber".

Black and brown are the easiest colors to obtain by overdyeing other colors. There should not be any difficulty, if your fabric is made of a dyeable material and is free of surface finishes that will resist the dye.

For disperse dyes, acid dyes, and direct dyes, you must cook your fabric in the dye; only cool water fiber reactive dyes allow for room temperature dyeing. For yards of fabric, this will require the use of an enormous cooking pot, or else professional dyeing equipment. It's not a small investment. It would make more sense for you to contact a local company that does custom dyeing, so that you do not have to invest in the equipment. Most custom dyers refuse to dye polyester, but are happy to dye cotton, rayon, or nylon. I have several custom dyers listed on my site on the following page:
Finding a Custom Dyer
Unfortunately, no dyers in the UK have registered for this page, so I cannot recommend someone in your area to do your dyeing for you. Good luck in finding someone.
