Industrial Applications of Fluorescent Brightener 220
| Industry | Application | Process |
|---|---|---|
| Textile Industry | Whitening treatment for polyester and polyester-blend fabrics | Added during high-temperature, high-pressure dyeing or thermosol dyeing to enhance fabric whiteness and brightness |
| Plastics Industry | Whitening of engineering plastics such as polyester and polyamide | Incorporated prior to plastic melt extrusion or injection molding to improve product whiteness |
| Coatings and Inks | Whitening additive for white coatings or light-colored inks | Dispersed into the coating/ink formulation to enhance hiding power and visual whiteness |
| Synthetic Fiber Manufacturing | Whitening in dope dyeing or post-treatment of fibers | Added to the spinning dope or applied via immersion during fiber heat-setting |
| Detergent Industry | Whitening agent in premium laundry powders/liquids (less common) | Formulated with other surfactants to deposit onto fabric surfaces during washing for whitening effect |
Manufacturing Quality Control of Fluorescent Brightener 220
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 345 nm, comparing peak area to calibrated standard. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration at 550-600 C and subsequent weighing. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a standardized 1% w/v aqueous dispersion using calibrated glass electrode. |
| Heavy Metals (as Pb) | AAS | Quantifies total heavy metals by atomic absorption spectroscopy after acid digestion and chelation. |
| Chloride Content | Potentiometric Titration | Determines chloride ions using silver nitrate titrant with silver/silver chloride indicator electrode. |
| Solubility in Water | Visual Inspection | Evaluates complete dissolution of 1 g sample in 100 mL distilled water at 25 C with mechanical stirring for 10 min. |
| Organic Impurities (Related Substances) | HPLC-DAD | Identifies and quantifies structurally related compounds using HPLC with diode-array detection and reference standards. |
| Bulk Density | ASTM D1895 | Measures mass per unit volume using a graduated cylinder and tapping method per ASTM standard procedure. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile residue after heating at 700 C for 30 min, expressed as percentage of original weight. |
| Color (APHA) | UV-Vis Spectrophotometry | Measures yellowness index in solution by comparing absorbance at 430 nm against APHA platinum-cobalt scale. |
