Textiles - Monofilaments - Determination of thermal shrinkage
This European Standard specifies three methods for the determination of shrinkage:
- Determination of shrinkage in hot air under tension;
- Determination of shrinkage in hot air without tension;
- Determination of shrinkage in hot water without tension.
