yes. the difference between a physical change and a chemical change is this: physical change changes its looks but it can be changed back. a chemical change changes its state of form and it can't be changed back. ex: an ice cube melting into water. you can always put the water in the freezer and it comes back as ice. but if metal rusts, there is no way you can change it back. so you can get a perfessional or a special cleaning device to remove the dye plus its still a cloth; therefore, it is a physical change.
