What is ISO 16322-2 about ?
ISO 163222 is a series on textiles. A textile is a flexible material made by creating an interlocking bundle of yarns or threads, which are produced by  spinning raw fibres (from either natural or synthetic sources) into long and twisted lengths. ISO 163222 specifies three procedures (diagonal marking, inverted-T marking, and mock-garment marking) to measure the spirality or torque of woven and knitted fabrics after domestic laundering. ISO 16322-2 is not intended to measure the spirality of fabrics as manufactured, but the spirality after laundering.
Who is ISO 16322-2 for ?
ISO 16322-2 on textiles is useful for:
- Textile laundering department
- Textile manufacturing industries
- Quality control personnel
Why should you use ISO 16322-2 ?
Textiles are then formed by weaving, knitting, crocheting, tatting, felting, bonding, or braiding these yarns together. Spirality or twisting in a garment is appeared after washing. As a result, one of the side seams comes at front of the garment when the wearer wears it. Spirality percentage depends on fabric torque and garment structure. ISO 16322-2 measures the spirality or torque of woven and knitted fabrics after domestic laundering.
Spirality has a definite influence on both the functional and aesthetic performance of knitted fabrics and their garments. Displacement or shifting of seams during the garment make-up mismatched patterns due to wale skewness, sewing difficulties, etc. are some important practical difficulties due to spirality. So, for better performance of the fabric, it is necessary to determine the spirality it will benefit the business for increase the performance of their business and goodwill. Using ISO 16322-2 you can specify three procedures to measure the spirality or torque of woven and knitted fabrics after domestic laundering.
What is changed since the last update ?
BS ISO 16322-2:2021 supersedes ISO 16322-2:2005. BS ISO 16322-2:2021 includes some technical changes with respect to ISO 16322-2:2005. These include:
- In normal assessment the absolute value of formula 1 has been specified
- Inverted-T marking (procedure B) after laundering and Mock-garment marking (procedure C) after laundering have been corrected
