ISO 16322-1:2005 specifies a method of measuring the percentage of wale spirality change in weft-knitted jersey garments produced on knitting machines, following laundering. The results obtained from different procedures may not be comparable. The change in spirality is calculated from measurements on knitted garments before and after laundering.

Overview
ISO 16322-1:2005, published by the International Organization for Standardization (ISO), specifies a standardized method for determining the percentage of wale spirality change in weft-knitted jersey garments following laundering. This part of the ISO 16322 series addresses the critical need to measure how much knitted fabrics, particularly those produced on knitting machines, twist or distort (spirality) after domestic or commercial washing procedures. Accurate assessment of spirality in textiles is essential for evaluating garment quality, appearance, and performance.
Key Topics
- Wale Spirality: The central focus is the distortion in which the vertical columns of knitted loops (wales) follow a spiral path, causing potential visual and structural issues in finished garments.
- Measurement Process: The standard outlines a procedure to measure the wale angle before and after laundering, using a calibrated straightedge and protractor for precise angle determination.
- Laundering Procedures: Specific washing scenarios are suggested, including simulated hand washing, machine washing per ISO 6330, or static soaking for dry-clean-only garments.
- Data Calculation: Results from measurements both before and after laundering are averaged and used to calculate the percentage change in spirality using a standard formula.
- Test Reporting: The standard prescribes clear and consistent reporting formats, including details of the sample, laundering method, and before-and-after spirality values.
Applications
ISO 16322-1:2005 has practical value across the apparel industry and laboratories specializing in textile testing. Typical applications include:
- Quality Assurance for Manufacturers: Ensures that knitted garments, such as T-shirts, sweaters, and sportswear, meet required spirality tolerance levels after washing, thereby reducing returns and complaints.
- Textile Research and Development: Provides a structured approach for evaluating new fabrics and garment constructions for performance after laundering.
- Compliance and Certification: Brands and retailers require compliance with ISO textile standards like ISO 16322-1 as a component of product specification and certification.
- Comparative Assessment: Enables benchmarking and comparison between different fabrics, finishes, or laundry processes, though direct comparisons between results obtained with different procedures are not valid due to potential methodological differences.
Related Standards
For comprehensive evaluation and consistency in textile testing, several other ISO standards interconnect with ISO 16322-1:
- ISO 139: Textiles - Standard atmospheres for conditioning and testing
- ISO 4921: Knitting - Basic concepts - Vocabulary
- ISO 6330: Textiles - Domestic washing and drying procedures for textile testing
- ISO 8388: Knitted fabrics - Types - Vocabulary
- ISO 16322-2 and ISO 16322-3: Extensions of the spirality determination addressing other garment and fabric types
Conclusion
ISO 16322-1:2005 provides a consistent, reliable, and internationally recognized method to assess the spirality change in knitted garments after laundering. By applying this standard, manufacturers and quality assurance professionals can maintain garment quality, ensure customer satisfaction, and meet industry requirements for textile performance and durability.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
