product details

Product Characteristics

Tracid Brilliant Blue 6B is a uniform powder of deep blue to blue-violet color with red light， without lumps or impurities.

Basic Physical and Chemical Properties

1. Color Characteristics： The aqueous solution of Tracid Brilliant Blue 6B shows extremely bright and vivid red light blue (colorful blue), with full and pure color light.

2. Dissolution Properties： Tracid Brilliant Blue 6B is insoluble in cold water， slightly soluble in hot water (80-90°C)， the aqueous solution is clear； it is slightly soluble in ethanol and appears bright blue； it is insoluble in organic solvents such as acetone， ether， and benzene.

3. Ion Nature： Strong anionic type， acid blue 83 combines with protein fibers through ionic bonds， suitable for weakly acidic baths (pH 4-6).

4. Acid-Base Stability： Stable in weakly acidic to neutral conditions； when exposed to concentrated alkali (NaOH)， it turns purple and precipitates.

5. Metal Ion Resistance： Acid blue 83 is sensitive to copper and iron ions； when exposed to iron， the color light becomes darker， and when exposed to copper， the color light becomes reddish.

6. Heat Stability： Good， stable at 90-95°C during dyeing， does not decompose at high temperatures.

7. Oxidation Resistance： Tracid Brilliant Blue 6B is resistant to common oxidants， but not to strong reducing agents.

Dyeing Performance and Application Points (Production Process Special)

1. Applicable Fibers： Suitable for dyeing and direct printing of wool， silk， and nylon (nylon)； mixed textiles of wool/silk and wool/nylon.

2. Dyeing Process： Weakly acidic bath (pH 4-6， adjusted with acetic acid / ammonium sulfate)， enter dyeing at 40-50°C， heat up to 90-95°C and maintain for 30-40 minutes.

3. Dyeing Characteristics：

1. Uniformity： Good， the dyeing process is gentle， and color bleeding is not likely.

2. Affinity： High， the dyeing rate on protein fibers is > 85%.

3. Color Matching： Acid blue 83 can be combined with acid yellow， orange to produce deep green， dark blue； with acid red to produce purple， black.

4. Wet Fastness： Excellent (water washing 4-5 grades， sweat staining 4-5 grades)， it is a mainstream product of Tracid Brilliant Blue 6B.

5. Cross-domain Applications：

1. Leather： Shoe leather， clothing leather， high-hardness bright blue coloring for fur.

2. Papermaking： Cultural paper， decorative paper， cigarette paper， card paper coloring.

3. Biological Dyeing： Karmasol Blue R250， used for protein electrophoresis gel staining (classic protein dyeing agent).

4. Others： Water-based ink， wood， bamboo products， soap， detergent coloring.

Common Precautions

1. Precise Color Light Distinction： Tracid Brilliant Blue 6B is a red light vivid blue color， significantly different from acid lake blue A (green light blue) and acid blue 9 (pure greenish blue). When purchasing， it is necessary to verify the C.I. number and color light samples.

2. Water Quality and Metal Ions： Tracid Brilliant Blue 6B must be used with soft water / deionized water. During dyeing， EDTA chelating agent must be added to prevent the color light from becoming darker and reddish due to copper and iron ions.

3. Dissolution Method： Acid blue 83 is fully dissolved in 80-90°C hot water and then added to the dye bath after cooling to the dyeing temperature to avoid lumps caused by direct cold water addition.

4. Compatibility and Fixation： Acid blue 83 can be combined with all weakly acidic / acid dyes； it is strictly prohibited to be in the same bath with cationic dyes (precipitation)； the wet fastness is excellent， generally no fixation is required， and the sunfastness is medium， which can be improved by adding UV absorbers.

5. Special for Biological Dyeing： For protein electrophoresis， a high-purity (HPLC ≥ 70%) reagent-grade product must be selected to avoid impurities affecting the clarity of dyeing.

6. Storage and Use： Seal and prevent moisture. After lumps form， crush and dissolve in hot water. This does not affect use； expired dyes should be tested for color light and solubility before use.

Packaging, Storage & Transportation

Standard package: 25kg woven bag / fibre drum. Store hermetically, keep dry. Do not store together with strong oxidants.
