Message: How can I remove colour of polyester by chemical? and by which chemical I can do it, with water and heat?

Avoid using chlorine-based bleaches, such as sodium hypochlorite (which is the active ingredient in most household bleach). They cause permanent damage to polyester in the form of a dull yellowish stain that cannot be removed.

Any of the sulfur-based color removers would be suitable for removing color from dyed polyester. See the "Reductive Discharges" section of my page, "What chemicals can be used to remove dye?". The most popular include sodium hydrosulfite, also known as sodium dithionite, which is in Rit Color Remover; thiourea dioxide, also known as formamidine sulfinic acid, found in Jacquard Color Remover. There are links on my page to instruction sheets for dye removal using some of the individual chemicals listed. I also posted instructions for using sodium hydrosulfite as a color remover in the Dye Forum in May of 2006, titled "How to use sodium hydrosulfite to discharge dye".

Note that not all dye colors can be removed. Some dyes are easy to remove, but others cannot be removed, no matter what you do. Unless you know exactly what dye was used on your material, the only way to find out whether it can be removed is to try it.
