Overview
SIST EN ISO 105-P02:2005 (ISO 105-P02:2002) defines a standardized method for determining the colour fastness of all types of textiles to the action of steam pleating. Colour fastness to pleating is a critical property for textiles that undergo finishing processes that impart durable creases or pleats using steam. This standard describes and specifies three different test procedures, each with varying levels of severity, to assess how well the colour of a textile resists alteration and staining from adjacent fabrics during steam pleating.

Key Topics
-
Scope of Application
- Assess the resistance of textile colours to steam pleating across fabrics, yarns, and fibers.
- Relevant for textiles in any form or composition, including blends of synthetic and natural fibers.
-
Test Methodologies
- Three distinct test severities (mild, intermediate, severe) to match the end-use requirements and expected finishing conditions.
- Use of a specimen holder and controlled steaming apparatus to simulate pleating conditions without actual mechanical pleating.
- Evaluation of both the alteration in the test specimen’s colour and potential staining of adjacent fabrics.
-
Assessment Tools
- Change in colour and staining measured and rated using internationally recognized grey scales.
- Standardized conditioning and drying procedures for specimen evaluation, ensuring consistent results.
-
Reporting Requirements
- Full documentation of test conditions, specimen details, ratings for colour change and staining, and identification of adjacent fabrics used.
Applications
The ISO 105-P02:2002 standard is highly relevant for:
- Textile Manufacturers: Ensures products maintain visual quality after steam pleating, helping minimize customer complaints related to colour change or staining.
- Textile Finishers: Offers guidance on evaluating materials before large-scale steam pleating processes, reducing the risk of production losses.
- Quality Control Laboratories: Provides a repeatable method for verifying the colour fastness of various textiles under steam exposure.
- R&D in Textile Industry: Assists in developing new fabrics or finishes with improved resistance to colour alteration due to heat and moisture.
- Importers and Exporters: Facilitates international trade by complying with recognized standards demanded by global supply chains.
Textile products that often undergo steam pleating include garments, home textiles (curtains, draperies), technical textiles, and decorative fabrics.

These related standards support the implementation of ISO 105-P02:2002 and help ensure consistency and comparability across various textile tests and applications.
Implementing SIST EN ISO 105-P02:2005 is a valuable step for any organization focused on textile quality assurance, product consistency, and international compliance in textile testing for colour fastness to steam pleating.
