Definitions
- the present invention relates to an improvement made to the oxidative bleaching processes carried out in an acid medium, by the action of hydrogen peroxide.
- bleaching in an alkaline medium is not suitable for certain fibers, such as synthetic fibers.
- other desiderata can rule out the use of an alkaline medium even with fibers, such as cellulosic fibers, which are not altered in such a medium. For example, we may want to keep the natural fats of fibers of vegetable or animal origin, fats which would be saponified in an alkaline medium.
- the Applicant has therefore looked into the problem of industrial improvement of bleaching in an acid medium, by the action of hydrogen peroxide.
- FR-A-2 471 437 describes a process for bleaching fibrous materials using hydrogen peroxide or alkaline peroxides in the presence of a stabilizing agent chosen from chlorites of alkali and alkaline earth metals.
- the pH of the bleaching bath can be between 4 and 13.
- the Applicant has experimentally found that the introduction of a chlorite and a small amount of a vanadate into an aqueous and acid dilution of hydrogen peroxide makes it possible to greatly increase the whitening activity of the acid oxidizing solution and of industrially perform bleaching under good pH and temperature conditions.
- the present invention therefore relates to a process for bleaching fibers using an acid solution of hydrogen peroxide, characterized in that the acid solution is activated using a chlorite and a vanadate chosen from vanadates of alkali metals and ammonium, present simultaneously in the acid solution, the chlorite being present in an amount of 0.1 to 10 g per liter of bath and the vanadate being present in the amount of 0.01 to 1 g per liter of bath .
- the acid pH range of the bath can be between 3 and 6 and the temperatures between 30 and 130 ° C, preferably between 60 and 90 ° C.
- the necessary amounts of sodium chlorite will preferably be between 1 and 4 g per liter of the bath.
- the necessary quantities of hydrogen peroxide will depend on the peculiarities of the bleaching process; these quantities could therefore be very variable and be, for example, between 1 and 100 g / l of a 35% hydrogen peroxide solution.
- the amounts of vanadate will preferably be between 0.1 and 0.4 g per liter of bleaching bath.
- An unbleached cotton fabric is treated by operating comparatively in baths respectively having the following composition:
- a fabric made up of cellulosic fibers, part of which has been dyed beforehand with reactive dyes in order to constitute a dyed fabric article, is treated in the respective bleaching baths having the following composition:
- a fabric consisting of unbleached cotton fibers and triacetate fibers is treated in the bleaching baths below, containing dispersed dyes, in order to dye the triacetate fiber at the same time as the bleaching of the cellulosic fiber.
- the following operating conditions are adopted: Bath ratio 1 to 10.
- the temperature of the baths is brought to 80 ° C., this temperature is maintained for 20 minutes, then the temperature is brought to 110 ° C.
- the sample from bath b has a weaker and duller coloration, the cellulosic fiber is not bleached and is heavily soiled by the dispersed dye.
