Overview

EN ISO 2313-2:2021 (ISO 2313-2:2021) specifies a standardized method for measuring crease recovery angle of textile fabrics using a vertically folded specimen. The procedure quantifies how well a fabric recovers from a crease by measuring the angle formed between the two limbs of a folded sample after removal of a creasing load. This part of the ISO 2313 series is applicable to all kinds of textile fabrics and is useful for quality control, product development and comparative testing.

Key topics and technical requirements

• Test principle: Folded specimen is creased under a specified load, load is removed, the specimen is rotated so the fold is vertical, and the crease recovery angle is measured.
• Load and contact area: A total load of 10.0 N ± 0.5 N applied on an area of 15 mm × 18 mm (weight-piece ≈ 1.019 kg).
• Specimen preparation:
  • Samples taken at least 150 mm from the selvedge.
  • Minimum 20 specimens (half oriented with short sides parallel to warp/wales/length; half parallel to weft/courses/right angles).
  • Folded face-to-face for half the specimens and back-to-back for the other half.
• Timing and measurement:
  • Load duration: 5 min ± 5 s.
  • Rapid crease recovery angle: read at 15 s ± 1 s after load removal.
  • Delay crease recovery angle: read at 5 min ± 5 s after load removal.
  • Measurement resolution: 0.5° (protractor or automatic tester).
• Apparatus: Loading device (weight-piece, specimen holder, pressure board), protractor or automatic tester (example in Annex A), timer, holder/rubber glove.
• Atmosphere: Conditioning and testing atmosphere per ISO 139 (standard atmospheres).
• Notes on variability: Fabric limpness, thickness or curl can affect measurement precision; use of interleaf (paper/foil) allowed if specimens tend to adhere.

Applications and who uses this standard

• Quality control laboratories in textile mills and finishing plants to monitor crease recovery performance.
• Apparel and home textile manufacturers for assessing suitability of fabrics for garments, shirts, dresses, linens and other end-uses where appearance after creasing matters.
• R&D and product development teams comparing treatments (finish, resin, mechanical processing) aimed at improving anti-crease properties.
• Third‑party testing and certification bodies performing standardized, reproducible crease recovery testing for specifications and claims.

Related standards

• ISO 139 - Standard atmospheres for conditioning and testing (referenced for conditioning).
• Other parts of the ISO 2313 series (see ISO website for the full list).
• EN ISO 2313-2:2021 is the CEN-adopted version; it supersedes EN 22313:1992.
