Surface active agents - Determination of wetting power by immersion (ISO 8022:1990 modified)
This European Standard specifies a method for determining the wetting power of a surface active agent in solution by immersion of a disc of raw cotton cloth in the solution. The method is applicable to all surface active agents, whatever their ionic character, used as wetting agents in neutral, slightly acid or slightly basic baths for textile applications. The method is not applicable to mercerizing agents (baths highly basic) or to carbonizing assistants (baths highly acid).
Grenzflächenaktive Stoffe - Bestimmung des Tauchnetzvermögens (ISO 8022:1990 modifiziert)
Diese Europäische Norm legt ein Verfahren zur Bestimmung des Tauchnetz- vermögens von Lösungen grenzflächenaktiver Stoffe mit einem Netzplättchen aus Baumwollgewebe fest. Das Verfahren ist anwendbar für Lösungen grenz- flächenaktiver Stoffe, unhabhängig von ihrem ionischen Zustand, die in neutralen, schwach sauren oder schwach alkalischen Textilbädern verwendet werden. Das Verfahren ist für Mercerisiermittel (stark alkalische Bäder) oder für Carbonisiermittel (stark saure Bäder) nicht anwendbar.
Agents de surface - Détermination du pouvoir mouillant par immersion (ISO 8022:1990 modifié)
La présente norme européenne prescrit une méthode pour la détermination du pouvoir mouillant d'un agent de surface par immersion d'un disque de tissu de coton écru dans la solution. La méthode est applicable à tous les agents de surface, quel que soit leur caractère ionique et servant comme agents mouillants dans les bains neutres, légèrement acides ou légèrement basiques, utilisés dans les applications textiles. La méthode n'est pas applicable aux adjuvants de mercerisage (bains fortement basiques) ou aux adjuvants de carbonisage (bains fortement acides).

Overview
EN 1772:2000 (Surface active agents - Determination of wetting power by immersion) is a European adoption of ISO 8022:1990 (modified) published by CEN. The standard specifies a laboratory method to determine the wetting power of a surface active agent (surfactant) in solution by immersing a disc of raw cotton cloth into the test solution. It is intended for surfactants used as wetting agents in textile processing baths that are neutral, slightly acidic, or slightly basic.
Key topics and requirements
- Test principle: determination of wetting performance by immersion of a raw cotton cloth disc into a surfactant solution (qualitative/quantitative evaluation of wetting power).
- Specimen: use of a disc of raw cotton cloth as the standard test substrate to represent textile wetting behavior.
- Applicability: method applies to surfactants of any ionic character (anionic, cationic, non-ionic, amphoteric) when used as wetting agents in textile baths of neutral to slightly acidic or slightly basic pH.
- Limitations: not applicable to highly basic mercerizing agents or highly acidic carbonizing assistants - these process chemistries require different test methods.
- Test conditions (general): includes preparation of test solution, immersion procedure, observation/recording of wetting behavior and any required environmental or handling controls as specified by the standard (refer to the full text for procedural detail).
- Reproducibility and reporting: requires standardized specimen preparation and reporting of results to support comparability between labs and formulations.
Applications
- Quality control: routine QC testing of surfactant batches to ensure consistent wetting performance for textile finishing and pretreatment.
- Product development: formulation screening and optimization of wetting agents used in dyeing, scouring, and other wet-processing steps.
- Supplier validation: verification of raw-material performance claims for surfactant suppliers and purchasing specifications.
- Process troubleshooting: diagnosing poor wetting issues in textile processes by comparing product performance against the standard test.
