Dispersant NNO used in dye grinding, standardization or dye-bath particle dispersion belongs to GreenAgrochem.net, the Green Agrochem Surface & Interface Technology Division. Performance must be qualified for the exact NNO grade, dye class, fibre, water, auxiliary package and temperature profile.
Use the complete Dispersant NNO for Dye Processing: Selection and Testing guide for dispersion-versus-wetting boundaries, dye/fibre screening, silk and silk/wool considerations, thermal evaluation, incoming control and wastewater review.
Former Specification and Process Data Status
| Former value | Evidence/status | Required treatment |
|---|---|---|
| CAS 36290-04-7. | Commonly associated with some commercial NNO/SNF condensation products, but identity can vary by supplier and jurisdiction. | Confirm the exact supplied product identity and registration information from its current SDS. |
| pH 7–9 for a 1% solution. | Possible grade property, but no current exact-grade TDS, method or product code was cited. | Do not publish as Green Agrochem specification until tied to the governing document and COA. |
| Approximately 130°C high-temperature dyeing. | Process example without dye, fibre, time, pH, water, NNO grade or stability method. | Reproduce the complete heating, hold and cooling profile; a temperature alone is not evidence of stability. |
| 25 kg lined woven bags. | Former packaging statement without a current exact-grade packaging specification. | Confirm net weight, liner, palletization and contract. |
Former Dosage and Reported-Result Status
| Former value | Evidence/status | Required treatment |
|---|---|---|
| Disperse/polyester 0.5–1.5 g/L; vat/acid dye 1–3 g/L; acid dye 1–2 g/L; naphthol base 2–5 g/L. | No exact grade, supplier source/revision, active-solids basis, liquor ratio or complete process was identified. | Not current supplier recommendations. Restore only as exact-grade starting trial ranges with defined basis and controlled validation. |
| Approximately 1.2% on fabric weight and up to/over 94% exhaustion for Disperse Red 177 in a waterless silicone system. | Unverified literature-style result without a primary citation, exact material, method or control. | Not Green Agrochem product data. Restore only after verifying the source and preserving the full experimental system beside the result. |
Claims Requiring Dye-System Evidence
| Former claim | Status | Correct approach |
|---|---|---|
| Universally soluble in any water, stable to acid/alkali/heat/salts and non-foaming. | Unsupported universal compatibility and performance. | Test actual water, pH, electrolyte, temperature curve, dye and auxiliary package; assess foam separately. |
| Guarantees dispersion, uptake, uniform colour, penetration, fastness, no cross-staining and fewer defects. | Unverified textile outcomes. | Measure particle size, filtration, deposits, shade, levelness, build-up, washing-off and fastness against a matched control. |
| Non-toxic, non-flammable, non-explosive, safe and environmentally preferable. | Absolute safety/environmental wording unsupported without exact-grade documents. | Use the current SDS, occupational controls, wastewater assessment and applicable regulations. |
Information Required for a Trial
- Dye identity/class and particle-size target.
- Fibre/blend, liquor ratio, water, pH, salts and auxiliaries.
- Temperature curve, shear/circulation and addition sequence.
- Current dispersant, target defect, filtration, shade and fastness methods.
- Exact-grade TDS, SDS, representative COA and sample requirements.
