EN ISO 12945-2 Determination of fabric propensity to pilling Martindale method
The EN ISO 12945-2 standard is used to determine the fabric propensity to pilling using the Martindale method. This test evaluates the resistance of textile fabrics to pilling, which is a common issue in clothing and other textiles that can lead to an unsightly appearance and reduced durability.
Pilling refers to the formation of small balls or clumps on the surface of fabric due to rubbing against other surfaces. This phenomenon occurs more frequently with fabrics made from synthetic fibers like polyester, but it can also affect blends with natural fibers such as cotton or wool. The Martindale method is a standardized procedure that simulates real-world conditions by subjecting samples to repetitive friction.
The test involves placing the fabric specimen onto a rotating drum and rubbing it against a series of pins at specified pressures, cycles, and speeds. After reaching a predetermined number of cycles (typically 5000), the sample is visually inspected for pilled areas. The results are then compared to reference standards to determine compliance.
Understanding fabric pilling propensity is crucial for quality managers, compliance officers, R&D engineers, and procurement specialists working in sectors like clothing manufacturing, automotive interiors, and home textiles. By identifying fabrics with low pilling tendencies early in the development process, manufacturers can enhance product performance, reduce waste, and ensure regulatory compliance.
The Martindale method is widely recognized for its ability to replicate real-world wear and tear conditions accurately. This makes it an essential tool for evaluating fabric quality across various applications where aesthetics and durability are critical factors.
Scope and Methodology
| Parameter | Description |
|---|---|
| Fabric Type | The test applies to woven and knitted fabrics, including blends. |
| Sample Preparation | Cut the fabric into a 10 cm x 20 cm rectangle. Ensure the sample is free from defects. |
| Testing Machine | The Martindale machine must comply with EN ISO 12945-2 requirements, featuring specific dimensions and settings for the test drum and pins. |
| Pinning Pressure | Ranges from 80 to 160 grams per square centimeter (g/cm²) depending on fabric type and expected wear conditions. |
| Cycles | 5000 cycles are standard, but this may vary based on specific requirements or standards. |
| Speed | The drum rotates at a speed of 80 revolutions per minute (rpm). |
| Pin Size and Distribution | Standard pins are used to replicate real-world rubbing conditions. |
