or orange component as a result of the differences in chemical structures in order to achieve the objects of the invention it is generally required to determine the type of dye or colorant that has been utilized in order to arrive at the proper parameters to oxidize the colorants without affecting either the fibers or the colorant within the fiber in the case of synthetic fibers such as polyesters the dye within the fiber is slightly affected by the ozone and the ozone has little effect in degrading the fibers the colorant or dye on the surface of the fiber is therefore exposed to the oxidation effects of the ozone generally temperatures between 50 u00b0 and 120 u00b0 f preferably between 50 u00b0 and 100 u00b0 f are sufficient to dissolve the oxidation components of the colorant or dye utilized cellulosic fibers because of the reactive dyes require higher temperatures generally about 80 u00b0 120 u00b0 f many dyes can also be treated at ambient temperatures black dyes are an exception because most black dyes comprise more than one dye and care must be taken so as to decolorize only the surface dye which causes the discoloration combination of yarns formed with polyester and cotton fibers many times are dye plated at the twists of the fibers in accordance with one embodiment of the invention ozone is produced according to u s pat nos 5 366 510 and 5 939 030 which are herein incorporated by reference for use either in a dye bath or after rinsing the dyed textile ozone may be.
