Overview
ISO 9348:2026 defines a standard digital measurement method for assessing the anti-contamination propensity of textiles to particulate matter (PM). Developed by the International Organization for Standardization (ISO), this methodology is specifically tailored for woven fabrics, including those treated or untreated with anti-contamination finishes. It is particularly relevant for testing apparel textiles but is not suitable for fabrics that interact with UV light, allow PM penetration into fiber structure, or are designed for personal protective equipment.
Accurate measurement of how well fabrics resist particulate contamination is crucial for ensuring the cleanliness, durability, and comfort of textile products, especially in environments with high concentrations of ambient particulates.
Key Topics
- Particulate Matter Definition: Follows ISO 16890-1 for PM, focusing on solid airborne particles that adhere to fabric surfaces mainly due to electrostatic or surface interactions.
- Digital Measurement Method: Utilizes digital imaging under UV light and image analysis software to determine the area of particle adhesion, ensuring precise and reproducible results.
- Scope and Limitations:
- Suitable for woven fabrics intended for apparel
- Not suitable for UV-reactive fabrics, fabrics with significant PM penetration, or PPE textiles
- Sample Preparation and Test Procedure:
- Involves conditioning both test particles and textiles, using a rotary testing box and specimen canisters
- After exposure, specimen surfaces are imaged for analysis
- Result Expression: The proportion of surface area covered by PM is calculated and reported as a performance percentage, providing a quantitative assessment of anti-contamination effectiveness.
Applications
Implementation of ISO 9348:2026 enables:
- Quality Control in Textile Manufacturing: Textile producers and apparel brands can objectively evaluate and compare the anti-contamination performance of different fabric types and finishes.
- R&D for Advanced Textile Finishes: Research teams can assess the efficiency of new fabric treatments intended to minimize particulate adhesion.
- Compliance and Certification: Testing laboratories can use this standard to certify fabrics for specific requirements related to cleanliness and particulate resistance.
- Product Development for Apparel: Designers and manufacturers of garments for sensitive applications (e.g., medical, laboratory, or cleanroom environments) can ensure their fabrics meet rigorous standards for limiting particulate contamination.
- Environmental Impact Assessment: Organizations can monitor how textiles interact with airborne particulates, supporting sustainability initiatives and improved indoor air quality.
Related Standards
Several ISO standards complement and support ISO 9348:2026 in the field of textile testing and particulate analysis:
- ISO 139 - Textiles - Standard atmospheres for conditioning and testing: Outlines environmental conditions for reliable textile testing.
- ISO 16890-1 - Air filters for general ventilation - Technical specifications related to particulate matter.
- ISO 12945-1 - Fabric propensity for pilling tests, sharing apparatus similarities.
- ISO 13320 - Particle size analysis - Laser diffraction methods, relevant for PM characterization.
