Colorfastness and Shrinkage

SGS tests textiles for colorfastness and shrinkage, against national and international standards, to ensure the garment’s color quality, size and shape remain intact when washed, exposed to light or rubbed.

Gaining our independent verification of your product’s quality can help boost your reputation and add to your brand value. You also save time and money thanks to the geographical scope of our network, which allows us to provide an efficient and effective service in all the main textile manufacturing countries.

Our laboratories – recognized by reputable accreditation schemes – test according to the relevant industry standards. For example:

• BS EN ISO 105-B07 – Colorfastness to light, on textiles wetted with artificial perspiration, as designated by the British Standards Institute, European Union and International Organization for Standardization
• AATCC Test Method 125: Colorfastness to perspiration and light, as designated by the American Association of Textile Chemists and Colorists

Colorfastness to perspiration and light is a major issue in textile products, and concerns the resistance of dyestuffs to the influence of those factors. We perform the following physical tests, assessing colorfastness to:

• Chlorinated water
• Light
• Perspiration
• Phenolic yellowing
• Rubbing – dry and wet
• Sea water
• Washing
