example 1

[0033] The preparation of example 1 direct scarlet dye sol dyeing solution

[0034] 45 parts of ethanol, 6 parts of ethyl orthosilicate, 40 parts of water and 1 part of 3-glycidyl ether trimethoxysilane (GPTMS) were successively added into the three-necked flask. Stir on a magnetic stirrer (300r / min) for 20min. Under this condition, 2 parts of hydrochloric acid with a concentration of 0.01mol / L is added dropwise to the above-mentioned mixed solution at a speed of 40 drops / min, and then added to the mixed solution at 55 Add 6 parts of direct scarlet 4BS staining solution (concentration 2%) dropwise at a rate of drop / min. After the dropwise addition, the rotating speed of the magnetic stirrer was adjusted (400r / min), and the stirring was continued at room temperature for 24 hours to obtain a sol staining solution.

[0035] Direct Red 4BS (C.I.Direct Red 23) structural formula:

example 2

[0037] The preparation of example 2 reactive brilliant blue dye sol dyeing solution

[0038] 50 parts of ethanol, 9 parts of ethyl orthosilicate, 33 parts of water, and 2 parts of 3-glycidyl ether trimethoxysilane (GPTMS) were successively added to the three-necked flask. Stir on a magnetic stirrer (300r / min) for 20min. Under this condition, add 1 part of 0.01mol / L formic acid dropwise to the above mixed solution at a speed of 50 drops / min, and then add it to the mixed solution at a rate of 60 drops / min. Add 5 parts of Reactive Brilliant Blue KN-R dye solution (concentration 1%) dropwise at a speed of min. After the dropwise addition, the rotating speed of the magnetic stirrer was adjusted (400r / min), and the stirring was continued at room temperature for 24 hours to obtain a sol staining solution.

[0039] Reactive Brilliant Blue KN-R (C.I.Reactive Blue 19), the structural formula is:

[0040]

Embodiment 3

[0041] Embodiment 3 direct scarlet dye sol dyeing solution pad dyeing

[0042] Under the action of magnetic stirrer stirring (200r / min), directly add 5% sodium chloride to the dyeing liquid of scarlet dye sol. Using the colored sol solution as the dyeing solution, pad-dye the plain poplin cotton fabric (the dye concentration is 1%), dipping twice and padding, the excess rate is 80%, pre-baking at 50°C for 30min, and then baking at 150°C 5min. Finally, the fabric is washed, soaped, washed and dried to complete the dyeing.

[0043] The plain poplin cotton fabric dyed by the above has a soaping fading fastness of grade 3.5, a soaping staining fastness of 4 grades, a dry rubbing fastness of 3 grades, and a wet rubbing fastness of 2.5 grades. At the same time, the dyeing K / S value reaches Got 27.3.

Abstract

The invention discloses a method for preparing a sol dyeing solution and an application of the sol dyeing solution in dyeing of a textile, belonging to the spinning chemical technical field. The method directly adopts a dye or an active dye, a precursor, a coupling agent, a solvent, and a catalyst to prepare the sol dyeing solution. The dyeing by the method has simple technique, does not need the independent fixing agent to perform the fixing process, has small pollution and effectively increases the dyeing depth of the textile.

Description

technical field [0001] The invention belongs to the technical field of textile chemical industry, and in particular relates to the preparation and application of a sol dyeing solution. Background technique [0002] The sol-gel method refers to the method in which inorganic substances or metal alkoxides are solidified through solutions, sols, and gels, and then heat-treated to form oxides or other compound solids. Sol-gel methods are used in a variety of industries. In recent years, the sol-gel method has been increasingly used in the textile industry. [0003] At present, the fastness requirements of export textile fabrics and clothing are getting higher and higher, but many water-soluble dyes still have low fastness to friction, soaping, and sunlight, such as the soaping of direct lightfast emerald blue GL The fastness is only grade 1, the wet rubbing fastness is only grade 2, and the dry rubbing fastness is only grade 3. In addition, there is still the problem of low ut...
