EN ISO 14419 Determination of oil repellency of treated fabrics
The EN ISO 14419 standard provides a method for determining the oil repellency of treated fabrics. This is achieved through the measurement of the contact angle between an oil droplet and the fabric surface. The test measures how water-repellent (hydrophobic) or oil-repellent (oleophobic) a textile material is after treatment.
The process involves placing a small amount of hexadecane on the fabric specimen, which simulates real-world conditions where oils such as cooking fats and greases might come into contact with fabrics. The fabric's resistance to these substances is then assessed by measuring the contact angle formed between the oil droplet and the fabric surface.
The higher the contact angle, the better the repellency of the fabric against hydrophobic liquids like water. For oils such as hexadecane, a lower contact angle indicates greater repellency. This method is widely used in sectors where fabrics are exposed to oil-based contaminants, such as in automotive interiors or industrial garments.
The test methodology involves several steps:
- Preparation of the fabric specimen according to EN ISO standards
- Application of a measured volume of hexadecane on a specific area of the fabric
- Measurement of the contact angle using optical techniques
- Evaluation and reporting based on the results
The test is particularly important for industries such as automotive, where fabrics are exposed to oil-based contaminants. The ability to repel oils can prevent the accumulation of dirt, which in turn extends the life of the fabric.
| Step | Description |
|---|---|
| 1 | Preparation of fabric specimens according to EN ISO 14419 standards. |
| 2 | Application of hexadecane oil droplets on the prepared specimen surface. |
| 3 | Measurement of contact angles using an optical device. |
| 4 | Evaluation and reporting based on the measured contact angle. |
Why It Matters
The determination of oil repellency is critical for several industries, particularly those dealing with harsh environments or where prolonged exposure to oils and greases is a concern. In the automotive sector, for example, fabrics are often exposed to engine oil and other hydrocarbons during use.
Repellency ensures that these materials remain clean and functional over their intended lifetime, reducing maintenance costs and improving overall product performance. This test also helps in quality control by ensuring that the products meet stringent industry standards and customer expectations.
The importance of this test extends beyond automotive applications to other sectors such as industrial wear, where workers may be exposed to oils and chemicals during their work. In these contexts, oil repellency can help protect workers from contamination, enhancing safety and comfort.
Industry Applications
- Automotive interiors: Ensuring fabrics remain clean and functional despite prolonged exposure to engine oil and other hydrocarbons.
- Industrial wear: Protecting workers from contamination by oils and chemicals, enhancing safety and comfort.
- Clothing for outdoor use: Maintaining the integrity of fabrics in harsh weather conditions where rainwater and oils may accumulate.
- Hospital textiles: Preventing the accumulation of contaminants that could lead to hygiene issues and increased cleaning costs.
