Definitions
- the present invention relates to a process for fixing dyes produced with direct and reactive dyes on cellulosic fibers.
- the application of a fixing agent is carried out after dyeing according to the conventional methods of application carried out or by exhaustion in a long bath, or continuously or semi-continuously.
- the application of a fixing agent can also be carried out during a finishing operation, particularly during treatments carried out using thermosetting resins intended to modify the physical characteristics of an article.
- a strengthening of the fixing power of the fixatives introduced resulting in an improvement in the solidity of the colors produced.
- the improvement manifests with direct and reactive dyes.
- the conditions of the present invention make it possible to improve wet solidities, such as, for example, solidities in washing, in water, in sweat, etc.
- the present invention therefore relates to a process for fixing dyes produced in direct or reactive dyes on cellulosic fibers, according to which a zirconium salt is added to conventional fixatives.
- fixatives are those usually used to improve the solidities of direct or reactive dyes, for example the condensation products of formaldehyde with the compounds comprising in their molecule at least one amino group, such as the condensation products of formaldehyde with guanidine, the aminotriazine, aminoguanidine, dicyandiamidine biguanidine and dicyanodiamide.
- the zirconium salt is zirconium oxychloride.
- the fixing method according to the invention is, in the case of reactive dyes, advantageously carried out directly after dyeing, without an intermediate washing operation.
- the resins used are those currently known and used to achieve the permanent finishing of cellulosic articles, such as resins based on urea-formaldehyde, melamine-formaldehyde, glyoxal-carbamate, etc.
- the quantity of fixative used can vary according to the requirements of the article under consideration, this quantity possibly being between 0.1 and 50% relative to the weight of the fiber, and preferably between 1 and 5% by compared to fiber.
- the amount of zirconium salt is also introduced according to the desired results may be varied between 95% and with respect to the q uan- tity scavenger introduced, and is preferably between 20 and 40%.
- the dyeing of the cellulosic fibers is carried out according to conventional dyeing methods, currently known; fixing is carried out after dyeing according to the impregnation and drying processes
- a previously bleached and hydrophilized cotton fabric is dyed with a direct dye, the reference to the Color Index is Blue Direct 78.
- Dyeing is carried out by exhaustion according to the conventional process at a temperature of 95 ° C in the presence of sodium chloride.
- the impregnation is carried out at a temperature of 20 ° C., the quantity of bath absorbed is expressed between the rollers of a scarf so as to retain 80% of the impregnation bath relative to the weight of the fiber, then dried immediately the material impregnated on the oar for 2 minutes at the temperature of 120 ° C.
- a second sample is treated under identical conditions, after adding 2 g per liter of ziconium oxychloride in the previous impregnation bath.
- the fixing is carried out using a fixing agent resulting from the condensation of biguanidine with formaldehyde.
- a previously bleached and hydrophilized cotton fabric is dyed using a reactive dye, the reference to the Color Index is Blue Reactive 3.
- Dyeing is carried out according to the so-called conventional Pad-Therm process (padding-heat treatment).
- the impregnation is carried out at a temperature of 20 ° C., the sample is then expressed between the rolls of a scarf so as to retain 80% of the impregnation bath relative to the weight of the fiber, then dried on a ream for 2 minutes at 120 ° C.
- a previously bleached and hydrophilized cotton fabric is dyed using a reactive dye, the reference to the Color Index is Reactive Blue 137.
- Dyeing is carried out using the conventional Pad Steam process (padding, spraying).
- the washing fastness test at 60 ° C and 95 ° C also shows a higher resistance of the color having been treated in the presence of zirconium.
- Determining the nervousness of the articles obtained also makes it possible to highlight an improvement of the order of 15% in the nervousness of the fiber on the samples made in the presence of zirconium salts.
