Industrial Applications of BASIC BLUE 3
| Industry | Application | Process |
|---|---|---|
| Textile dyeing and printing industry | Dyeing of acrylic (polyacrylonitrile) fibers and their blended fabrics | Exhaust dyeing: Dye uptake via ionic bonding in an acidic bath (pH 4–5), followed by temperature ramping and holding; Pad dyeing: Suitable for continuous pad dyeing or jigger dyeing. |
| Textile dyeing and printing industry | Direct printing on acrylic fiber fabrics | Printing paste preparation: Dissolve dye and incorporate into printing thickener; fixation via atmospheric steaming, followed by rinsing and soaping. |
| Papermaking industry | Tinting and dyeing of cultural paper, decorative paper, and specialty papers | Wet-end dyeing: Direct addition to pulp suspension, leveraging cationic groups to bind with negatively charged fibers; Surface dyeing: Applied via coating or impregnation of paper surfaces. |
| Leather industry | Dyeing of leather, particularly chrome-tanned leather | Post-tanning dyeing: Conducted under acidic conditions, where dye cations bind to anionic sites in leather to enhance color appearance. |
| Chemical industry | Raw material for preparing compound dyes | Compounding process: Blended with other dye classes (e.g., acid dyes) to formulate one-bath dyeing auxiliaries. |
Manufacturing Quality Control of BASIC BLUE 3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic lambda-max in standardized solvent system. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| Ash Content | Gravimetric Analysis (Weight Loss on Ignition) | Determines inorganic residue after controlled high-temperature combustion and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal impurities after acid digestion using plasma-induced atomic emission. |
| Chloride Ion | Potentiometric Titration with AgNO3 | Measures Cl- concentration by titration with silver nitrate using silver indicator electrode. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of 1% w/v aqueous dye solution using calibrated glass electrode. |
| Water Solubility | Visual Inspection & Filtration | Assesses complete dissolution in distilled water at specified temperature and concentration; absence of residue confirms solubility. |
| Substantivity (Relative Affinity to Cotton) | Dyeing Test + Reflectance Measurement | Evaluates dye uptake on standard cotton fabric via K/S value comparison after standardized exhaustion dyeing. |
| Fastness to Light | ISO 105-B02 | Measures color change after exposure to xenon arc lamp under controlled irradiance and humidity per ISO standard. |
| Fastness to Washing | ISO 105-C06 | Evaluates color change and staining after laundering under specified conditions (AATCC/ISO reference fabrics). |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder using Mie scattering theory applied to laser beam diffraction pattern. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
