Definitions
- the present invention relates to an improvement made to the oxidation and fixing of sulfur dyes, or vat dyes.
- the Applicant has on the other hand experimentally found that the presence in a bath of hydrogen peroxide, of small quantities of a metal salt, such as copper sulphate, quantities insufficient to increase the speed of oxidation and allow the development of the various colors, and simultaneously the presence in the bath of small quantities of a vanadate, makes it possible to quickly oxidize all the colors without having the disadvantage of modifying their tone.
- a metal salt such as copper sulphate
- the present invention therefore relates to a process for the oxidation of the dye of a fabric or fiber dyed with a sulfur dye or a vat dye using a solution of hydrogen peroxide in the presence of a salt.
- vanadate at a pH between 3 and 6 and at a temperature between 20 and 95 ° C, the proportions of hydrogen peroxide and vanadate salt being respectively between 0.1 and 30 g and between 0.05 and 0.5 g per liter of bath, characterized in that the oxidation is carried out in the simultaneous presence of a metal salt chosen from copper, iron, nickel, cobalt and manganese salts, the amount of this salt being between 0.01 and 1 g per liter of oxidizing bath.
- the oxidation is carried out at temperatures between 40 ° and 60 ° C.
- the vanadate can be chosen from the family comprising vandates of alkali metals and ammonium vanadate.
- the amount of hydrogen peroxide will be between 1 g and 5 g of hydrogen peroxide per liter of oxidation bath.
- the amount of vanadate will preferably be between 0.1 and 0.2 g / l.
- the amount of the metal salt will preferably be between 0.05 to 0.1 g per liter of bath.
- all the sulfur dyes or tank dyes can be oxidized whatever the dyeing process, the equipment used or the nature of the dyed fibers.
- a cotton fabric, previously bleached, is dyed with 10% sulfur red No. 10 (percentage expressed relative to the weight of the fiber).
- Oxidation is carried out on three separate portions of the f i-dyed fibers and rinsed, using the following baths respectively:
Landscapes
- Engineering & Computer Science (AREA)
- Textile Engineering (AREA)
- Coloring (AREA)
- Chemical Treatment Of Metals (AREA)
